Niacin, is also known as vitamin B3, nicotinic acid, an organic compound with the formula
C6H5NO2, found abundantly in chicken, beef, fish, cereal, peanuts and legumes.
It is best known for its effects in lowering cholesterol and
triglycerides and removing toxic from our body and promoting production
of steroid hormones.
Epidemiological studies, focused in niacin in reduced risk of breast
cancer have produced conflict results. In human breast cancer cell,
combination of niacin and butyrate
induced apoptosis, through activation of GPR109A, a G-protein-coupled
receptor in inhibition of genes, involved in cell survival and
anti-apoptotic signaling(1). But in the study of breast cancer risk among Chinese women, niacin was found to be associated with ER+/PR+ breast cancer
risk depending to the highest vs. lowest quartile of intake in
premenopausal women(2). Unfortunately, some researchers indicated that
regardless to the doses, even Mega-dose vitamins and minerals did not
improve the breast cancer-specific survival and disease-free survival times in breast cancer patients(2a).
The study of potent antioxidant Niacin (CoRN), co administration with
Tamoxifen (TAM) showed favorable impact on various blood chemistry
profiles and may be considered as a co-administrating antioxidants with
conventional chemotherapy but large scale randomized studies over a
longer time span are required to ascertain the safety and efficacy(3).
In tumour angiogenesis, the co administrations also decreased the levels
of pro-angiogenic factors which reduced the tumor burden in protection
from cancer metastases and
recurrence(4). Oral administration of daily supplement of 100 mg
co-enzyme Q10, 10 mg riboflavin and 50 mg niacin (CoRN), one dosage per d
along with 10 mg tamoxifen twice per day in breast caner patients
showed to reduce tumor burden by significant increase in
poly(ADP-ribose polymerase levels(Differentiation, proliferation, and
tumor transformation and Normal or abnormal recovery from DNA
damage) and disappearance of RASSF1A(involved in early tumorigenesis)
DNA methylation patterns(5). In postmenopausal women with breast cancer,
the above combination significantly increased the AO(antioxidants)
status, while decreasing lipid and lipid peroxides(free radical)(6).
Niacin is found effectively in reduced risk of breast cancer when co administrated. Combination with other vitamins and Tamoxifen (TAM) showed to
provide protection and management in the process of breast cancer
treatments, through exhibition of antioxidants status and decreased free
radical expression. Please make sure to follow the guideline of the
Institute of Medicine of the National Academies. Overdoses of vitamin B3 may induce symptoms of severe skin
flushing combined with dizziness, rapid heartbeat, itching, nausea,
vomiting, abdominal pain, etc.

Breast cancer in Vitamin B2's Points of view
Kyle J. Norton
Vitamin B2 also known as Riboflavin, is a water-soluble, yellow-orange organic compound found abundantly in milk, meat, eggs, nuts, enriched flour, green vegetables, etc. The vitamin is essential for normal cellular growth and function and best known for converting energy from protein, fat, and carbohydrates during metabolism and its antioxidant effects in oxidation-reduction reactions.
Breast cancer (malignant breast neoplasm) is a cancer that starts in the tissues of the breast either from the inner lining of milk ducts (Ductal carcinoma) or the lobules (Lobular carcinoma) suppled the ducts with milk. There is also rare cases that breast cancer starts in other areas of the breast. In 2010, over 250,000 new cases of breast cancer were expected to be diagnosed in women in the U.S. alone and the risk of getting invasive breast cancer during life time of a women is 1/8.
Epidemiological studies, focusing in the benefits of vitamin B2 in reduced risk and treatment of breast cancer have produced inconclusive results. Serum levels of riboflavin (RF) was found significantly be decreased in over-expressed of RF carrier protein women with breast cancer. Administration of RF-targeted MMC-conjugate (mitomycin C (MMC)-conjugated N-(2-hydroxypropyl) methacrylamide (HPMA) [used as macromolecular carriers to enhance therapeutic efficacy and limit side effects of anti-cancer chemotherapeutic agents] enabled an increase in MMC uptake and nuclear localization in cell cyle to induce cytotoxic activity in in both MCF-7 and SKBR-3 cells(1). In a follow-up of 20,756 women from the Melbourne Collaborative Cohort Study, including modification by age, hormone receptor status and alcohol consumption showed a insignificant evidence for an inverse association between breast cancer risk and riboflavin intake(2). Other in breast cancer risk among Japanese women, found no correlation of vitamin B2 intake and no overall association with breast cancer risk(3)(3a). Unfortunately, a 5-year survival rate study for in ER-/PR- breast cancers among Korean women, showed that a high intake of vitamin B2 and folate statistically elevated the HR of breast cancer progression compared to a low intake(4).
In postmenopausal women with breast cancer, Tamoxifen (TAM) co administration with Coenzyme Q(10), Riboflavin and Niacin (CoRN) exhibited a favorable impact on various blood chemistry profiles in reducing side effect of Tamoxifen causes of oxidative stress with various biochemical derangements(5), through increased the antioxidants status, while decreasing lipid and lipid peroxides(6)(7). In an 84 breast cancer patients randomized to receive a daily supplement of CoQ(10) 100 mg, riboflavin 10 mg and niacin 50 mg (CoRN), one dosage per day along with tamoxifen (TAM) 10 mg twice a day, supplementing CoRN decreased the levels of pro-angiogenic factors, increased the levels of anti-angiogenic factors and enhanced the efficacy of the treatment and might even offer protection from cancer metastases and recurrence(8)(9)(10). Energy-modulating vitamins, riboflavin (45 mg/kg body weight per d), niacin (100 mg/kg body weight per d) and coenzyme Q10 (40 mg/kg body weight per d) for 28 days in the experiment against mammary carcinoma induced by the oral administration of 7,12-dimethylbenz[a]anthracene (25 mg/kg body weight), showed an decreasing of the Krebs cycle and oxidative phosphorylation enzymes and may be considered as a major therapeutic value in breast cancer(11).
Taking altogether, vitamin B2 used conjunction with other energy vitamins and in co administration with Tamixofen showed to enhance the efficacy of the chemo-agent by exerting its antioxidant effects. In fact, risk of breast cancer are associated to nutrient deficiency of vitamin B-12, thiamin, folacin, iron, and riboflavin(12). Over doses for a prolong period may cause symptoms of skin rashes, hypersensitivity, high blood pressure etc., please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Breast cancer in Vitamin K's Points of View
By Kyle J. Norton
Vitamin K(K1, phylloquinone; K2, menaquinones), is a fat soluble vitamin, found abundantly in leafy green vegetables, broccoli, and Brussels sprouts, etc. It is best known for promotion of coagulation and bone health.
Epidemiological studies focused in the synthetic version of vitamin K(Vk3) in reduced risk and treatment of breast cancer have proven successful in certain extents. In comparison of the anti cancer effects of Vitamin K (VK) congeners, vitamin K3(Menadione ), a synthetic analogue with the same properties as provitaminis was found to be most potent in treating various types of cancer, including breast cancer(1) In comparison the inhibition effects of vitamin K, K3 and warfarin in human cancer cell lines, the combination of 3 Completely inhibited of L1210 growth in flask culture at concentrations of 200 micrograms/ml of warfarin, 75 micrograms/ml of vitamin K1, and 4 micrograms/ml of vitamin K3. The combination K3 and warfarin enhanced cytotoxicity at doses depending manner. Vitamin K3 alone was also cytotoxic in a concentration of 1 micrograms/ml, including breast cancers(1a). Synthesized VK2 derivatives (MQ-1, MQ-2 and MQ-3, also in the comparison of the antitumor activities of vitamin K1, K2, and K3 against a panel of human cancer cell lines, vitamin K3 showed inhibition of various cancers and radioresistant cancers including breast cancer cell lines (BC-M1)( in doeses of 26, 15, 25, and 33 microM: VK1 ranged from 6 to 9 mM, and VK2 ranged from 1 to 2 mM in ID50 values(1b).
In breast cancer, vitamin K3 analogue plumbagin exerted its inhibitor effect in osteoclastogenesis induced by tumor cells and breast cancer-induced osteolytic metastasis through suppression of RANKL signaling to alter tumor progression(2). In breast cancer cell line MCF-7, VK(3), it exhibited cytotoxicity through DNA fragmentation (separation or breaking of DNA strands into pieces) and mitochondrial dysfunction(3).
In MCF-7, estrogen receptor-positive breast cancer cells, vitamin K3 (menadione) inhibited the transcriptional activity of 17beta-estradiol in a reporter gene assay(4). CR108, a novel vitamin K3 derivative, (S)-2-(2-hydroxy-3-methylbutylthio)naphthalene-1,4-dione, exhibited apoptosis in both the non-HER-2-overexpressed MCF-7 and HER-2-overexpressed BT-474 breast cancer cells, through induced the loss of mitochondrial membrane potential, leading to cytochrome c released from mitochondria to cytosol and and cleaved PARP(activate CNS immune responses) proteins(5). Menadione, also known as VK3, its reduction-oxidation, generated by ascorbate-driven menadione redox cycling inhibited MCF7 breast cancer cells, through glycolysis(metabolic pathway for generation of energy) inhibition, loss of calcium homeostasis(maintains adequate calcium levels), DNA damage and changes in mitogen activated protein kinases (MAPK)(regulate proliferation, gene expression, differentiation, mitosis, cell survival, and apoptosis ) activities(6). Also, in MCF 7 breast cancer cells, Fluorinated Cpd 5, an arylating K-vitamin derivative, showed growth inhibition probably via conjugation of cellular thiols, by suppressing the activity of thiol containing cellular protein tyrosine phosphatase (PTP) enzyme(play critical roles in fundamental biological processes), with consequent induction of various tyrosine phosphoproteins(involved in a number of metabolic and signalling pathways) in promoting mutation cell proliferation(7).
Vitamin K although was found effectively in decreased risk and treatment for breast cancers by exhibition of its effects in cytotoxicity, apoptosis and anti proliferation through DNA fragmentation, mitochondrial dysfunction, cell death pathway, overdoses can induce symptoms of Skin rash, Diarrhea, Nausea, Vomiting, Anemia, etc. Please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Breast cancer in Vitamin D's Points of View
Kyle J. Norton
Vitamin D is a fat-soluble secosteroids found in small amount in few foods, including salmon, mackerel, sardines and tuna. The vitamin plays an important role in modulation of cellular proliferation, apoptosis induction, tumor growth suppression and promotion in absorption of minerals, including calcium, iron, magnesium, phosphate and zinc.
Breast cancer (malignant breast neoplasm) is a cancer started in the tissues of the breast either from the inner lining of milk ducts (Ductal carcinoma) or the lobules (Lobular carcinoma) which supply the ducts with milk. There is also rare cases of breast cancer started in other areas of the breast.
Epidemiological studies, linking vitamin D in reduced risk of breast caner focused in levels and plasma levels of vitamin D are still on debates. It may be due to age of subjects, menstrual stage, race, etc.. But the prevalence and wide spread of breast cancer have caused some concerns in the governments and researched community. Every year, over 250,000 new cases of breast cancer were expected to be diagnosed in women in the U.S. alone and the risk of getting invasive breast cancer during life time of a women is 1/8.
Levels of free circulation of vitamin D are correlated with risk of Breast cancer
Suggestions of levels of plasma 25-hydroxyvitamin D (25(OH)D) in a breast cancer risk differentiation by menopause, showed an inverse association beyond a threshold of 27 ng/mL, but with flattening of effects above 35 ng/mL(1)and low levels of 25(OH)D are at higher risk of breast cancer(1). In Chinese breast cancer patients low vitamin D status was found to be associated to increased risk of breast cancer(2). In breast cancer risk in an Australian population, in differentiation of plasma vitamin D levels indicated that 25(OH)D concentration below 75 nmol/L was associated with a significantly higher risk of breast cancer(3). In progesterone receptor negative breast cancer, restricted to premenopausal women only, plasma 25(OH)D concentrations. significant inverse association in breast cancer risk(4) In post postmenopausal breast cancer risk, Circulating 25(OH)D3 and 25(OH)D were found to associated with a reduced risk among whites, but not in other ethnic groups(5). In Genetic factor study, some vitamin D receptor (VDR) gene polymorphisms, such as Bsm1, poly(A), Taq1, Apa1 are associated to risk of breast cancer(6). 2,000 IU vitamin D-3 intake inhibited breast cancer proliferation through reduced COX2 expression(correlated with primary tumor size)(6a). Unfortunately, some suggested that vitamin D, regardless to dosage do not significantly affect breast cancer risk, treatment efficacy depending to highest dosage of vitamin D and in combination with calcium(6b).
The benefits
In a few randomized clinical trials (RTC) assessing whether either vitamin D intake or serum levels of 25 hydroxyvitamin D (25OHD) correlate (inversely) with cancer development, suggested that the vitamin D intake or serum levels of 25 hydroxyvitamin D (25OHD) reduced risk of cancers by exhibiting its anticancer effects, through the impact in a number of cellular mechanisms(7). In triple negative/basal-like breast cancer, 1,25-dihydroxyvitamin D3 (1,25D) suppressed multiple proteins that are required for survival of triple-negative/basal-like breast cancer cells through VDR in down regulated breast cancer invasion and metastasis and up regulated anti-profilaerative and apoptic expression(8). In Two VDRKO (KO240, KO288) and two WT (WT145, WT276) cell lines, 1,25-Dihydroxyvitamin D(3) (1,25D(3)), the active metabolite of vitamin D(3), inhibited the protein expression of VDR through induced G(0)/G(1) arrest and apoptosis in knockout (VDRKO) and wild type (WT) mice(9). In ER negative, invasive human breast cancer cell line SUM-159PT, 1,25(OH)(2)D(3) (1,25D(3)) and EB1089, a novel vitamin D analogue, reduced SUM-159PT cell growth subsequent to elevation of p27(regulator of cell cycle progression at G1 and S phase) and p21(cell cycle inhibitor) levels and inhibited SUM-159PT cell invasion through an 8 microM Matrigel (extract in measurement of the invasive activity of tumor cells)(10). In human breast cancer cell line MCF-7, Calcitriol, calcipotriol (PRI-2201) and tacalcitol (PRI-2191), the synthetic version of vitamin D, showed the antiproliferative activity. At higher doses of PRI-2202 or PRI-2205, the analog expressed their anti breast cancer activity similar to Tamoxifen through diminished mitochondrial membrane potential( in cell proliferation), as well as the increased phosphatidylserine (cell death) expression with increase in VDR expression in PRI-2201, but not PRI-219,(11). In MCF-7 breast cancer cells, 19-nor-2α-(3-hydroxypropyl)-1α,25-dihydroxyvitamin D3 (MART-10), a vitamin D analog(1000-fold more active than 1α,25(OH)2D3) suppressed MCF-7 cells growth through cell cycle arrest and apoptotic induction through the upregulation of E-cadherin(tumor suppressors), and the downregulation of Snail, Slug, and Twist, the transcription in regulate the expression of tumor suppressors such as E-cadherin(12). In BRCA1-deficient(loss of the DNA repair protein 53BP1) breast cancer cells, 1α,25(OH)2D3, an active form of vitamin D, stabilized 53BP1 levels in tumor cells and restored the levels of 53BP1, resulting in increased genomic instability in response to PARPi or radiation, and reduced proliferation(13). GcMAF, the vitamin D-binding protein-derived macrophage activating factor exhibited its anti breast cancers effects through stimulation of macrophages(a large white blood cell )in induction of apoptosis and eventually phagocytize them(14). HER2, accounted for approximately 20% of human breast cancer cases, Gemini vitamin D analog BXL0124, decreased activation of ErbB2 as well as other ErbB receptors, ErbB1 and ErbB3, through repression of activated-Erk1/2(cell regulation), activated-Akt(multiple cellular processes, including apoptosis), c-Myc(a regulator gene), CycD1(regulating cell cycle progression), and Bcl2(family of regulator proteins that regulate cell death)(15). In ER+ BCa., vitamin D suppressed the ER expression and estrogen-mediated signaling in BCa cells(16). In MCF-7 and MCF-7/VD(R) breast cancer cells, insulin-like growth factor I (IGF-I) in 1, 25-dihydroxyvitamin D3 (1, 25-D3)inhibited IGF-I/Akt pathways to cause apoptosis(17). In MCF10DCIS cells, Gemini vitamin D BXL0124 is found to decrease CD44 protein level(a transmembrane glycoprotein, is a major receptor for extracellular proteins involved in invasion and metastasis of human cancers), suppressed STAT3 (development, progression, and maintenance of many human tumors)signaling, and inhibited invasion and proliferation(18) and inhibited the growth of ErbB2 overexpressing mammary tumors through regulating the ErbB2/AKT/ERK(proliferation) signaling pathways in ErbB2-positive mammary tumor growth(18). In MCF-7 breast cancer cells, L-buthionine-S,R-sulfoximine, a glutathione-depleting drug enhanced inhibition of 1,25(OH)(2)D(3) in all transformed breast cell lines through ROS mediation induced apoptosis(19).
The disagreement of amount of vitamin D intake and plasma level in reduced risk and treatment of breast cancer may still need further studies, but the effective of vitamin D may not be denied. Over doses of vitamin D supplement may cause excessive calcium absorption, calcification, Urinary stones etc. please make sure to follow the guideline of the Institute of Medicine of the National Academies.

Vitamin D is a fat-soluble secosteroids found in small amount in few foods, including salmon, mackerel, sardines and tuna. The vitamin plays an important role in modulation of cellular proliferation, apoptosis induction, tumor growth suppression and promotion in absorption of minerals, including calcium, iron, magnesium, phosphate and zinc.
Breast cancer (malignant breast neoplasm) is a cancer started in the tissues of the breast either from the inner lining of milk ducts (Ductal carcinoma) or the lobules (Lobular carcinoma) which supply the ducts with milk. There is also rare cases of breast cancer started in other areas of the breast.
Epidemiological studies, linking vitamin D in reduced risk of breast caner focused in levels and plasma levels of vitamin D are still on debates. It may be due to age of subjects, menstrual stage, race, etc.. But the prevalence and wide spread of breast cancer have caused some concerns in the governments and researched community. Every year, over 250,000 new cases of breast cancer were expected to be diagnosed in women in the U.S. alone and the risk of getting invasive breast cancer during life time of a women is 1/8.
Levels of free circulation of vitamin D are correlated with risk of Breast cancer
Suggestions of levels of plasma 25-hydroxyvitamin D (25(OH)D) in a breast cancer risk differentiation by menopause, showed an inverse association beyond a threshold of 27 ng/mL, but with flattening of effects above 35 ng/mL(1)and low levels of 25(OH)D are at higher risk of breast cancer(1). In Chinese breast cancer patients low vitamin D status was found to be associated to increased risk of breast cancer(2). In breast cancer risk in an Australian population, in differentiation of plasma vitamin D levels indicated that 25(OH)D concentration below 75 nmol/L was associated with a significantly higher risk of breast cancer(3). In progesterone receptor negative breast cancer, restricted to premenopausal women only, plasma 25(OH)D concentrations. significant inverse association in breast cancer risk(4) In post postmenopausal breast cancer risk, Circulating 25(OH)D3 and 25(OH)D were found to associated with a reduced risk among whites, but not in other ethnic groups(5). In Genetic factor study, some vitamin D receptor (VDR) gene polymorphisms, such as Bsm1, poly(A), Taq1, Apa1 are associated to risk of breast cancer(6). 2,000 IU vitamin D-3 intake inhibited breast cancer proliferation through reduced COX2 expression(correlated with primary tumor size)(6a).

Breast cancer in Vitamin C's Point of View
By Kyle J. Norton
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin, found in fresh fruits, berries and green vegetables. It is best known for its free radical scavengers activity and regenerating oxidized vitamin E for immune support.
Epidemiological studies linking vitamin C in reduced risk of breast cancer may be inconclusive(1)(1a)(1b), but no doubt in acceptance of improved quality of life(2).
Macro nutrients intake may form an important parts in breast cancer patients in providing vital support for treatment.(3). There was a report of intake of supplementation of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer(3a).
Women with breast cancer in the Indian population, were found to have a lower levels of mean vitamin C, vitamin E and selenium than controls. if the levels of mean vitamin C, vitamin E and selenium increased by 1 unit, the risk of breast cancer was reduced by 7%(3b).
In breast cancer survival, dietary vitamin C intake before breast cancer diagnosis may be associated with breast cancer survival. but not in post-diagnosis(4). High intake of ascorbic acid was in associated to reduce risk of breast cancer incidence in overweight women and women with high consumption of linoleic acid (average consumption of more than 6 grams of linoleic acid per day)(5) and insignificant risk in other breast cancer patients(6). On inflammation in cancer patients, high dose intravenous ascorbic acid therapy, decreased the levels of C-reactive protein thus reduced inflammation correlated with decreases in tumor marker levels(7). Vitamin C supplements and Anthocyanin (Ixor®) at a dose of 2 tablets/day, starting from 10 days before the radiation treatment until 10 days after the end of treatment was found to be protective against skin damage to patient undergoing adjuvant chemotherapy(8).
In estrogen-induced breast carcinogenesis, vitamin C (Vit C) and butylated hydroxyanisole (BHA) found to be effective in inhibition of 17β-estradiol (E2)-mediated oxidative stress and oxidative DNA damage by preventing the decreasing NRF2(antioxidant response pathway) and OGG1(base excision repair.) levels(9). In the study of the same but in MCF-10A cells, the combination also decreased E2-mediated increase in 8-OHdG(Marker detected in cancer patients) levels in the mammary tissues, induced SOD3 (Extracellular superoxide dismutase [Cu-Zn]) through NRF2 Pathway to defense against oxidative stress and in the prevention of estrogen-mediated breast cancer(10).
An increased expression of the miR-93(Regulate Expression of Tumor Suppressor Gene) was found in 17β-estradiol (E2)-treated mammary tissues and in human breast cell lines, treatment with vitamin C reverted E2-mediated increase in miR-93 levels by upregulating expression NRF2 antioxidant response pathway(11). In 4T1 breast cancer cells in vitamin C-deficient mice, Ascorbic acid delayed the progress of metastasis, tumor growth and inflammatory cytokine secretion (decreased serum inflammatory cytokine interleukin (IL)-6) as well as enhanced encapsulation of tumors(12). In L-ascorbate (L-ascorbic acid, vitamin C), increasing the concentration exhibited the autophagic damage to functional SVCT-2(antibody) sensitizes breast cancer cells(13). In B16F10, L-ascorbate also caused induction of a prooxidant state, subsequent reduction in mitochondrial membrane potential to induced apoptosis in a caspase-8(Cell apoptosis)-independent manner(14). In the usage of glucan, resveratrol and vitamin C, the combination showed the strongest activator of phagocytosis (immune cell activation) and antibody formation to suppress the growth of breast and lung tumors, through stimulation of apoptosis(15). In 4T1 cancer cell line, combined with ascorbate, Mn(III)N-alkylpyridylporphyrins (MnPs) inhibited cancer cells via peroxide produced outside of the cell through enhancing tumour oxidative stress and tumor growth suppression(16). In Ataxia telangiectasia mutated (ATM) diplotype on the breast cancer, vitamin C enhanced the increase of ATM to reduce the risk of breast cancer.(17). In E(2) metabolism and oxidant stress in involved in estrogen-induced breast cancer development, vitamin C reducesd the incidence of estrogen-induced mammary tumors, increased tumor latency and decreases oxidative stress in vivo(18). In SK-BR3 and Hs578T breast cancer cell lines, Vitamin C treatment induced AIF(apoptosis-inducing factor) mediation of cell death pathway of the breast cancer cell lines independent to caspase pathway(19).
In human breast cancer cell line MCF-7, combination of Retinoic acid and ascorbic acid inhibited the proliferation of human breast cancer cells through altering their gene expression related to antioxidation processes and the proliferation inhibitory pathway(20).
Taking all together, without going into reviews, vitamin C is found to be effective in reduced risk and a potent agent for treatment of breast cancer. Daily ingestion of high-dose vitamin C may be considered safe, but in rare incidence, overdoses in a prolonged period of time, may cause intra-renal oxalate crystal deposition, a fatal nephrotoxicity(21)(22).

An increased expression of the miR-93(Regulate Expression of Tumor Suppressor Gene) was found in 17β-estradiol (E2)-treated mammary tissues and in human breast cell lines, treatment with vitamin C reverted E2-mediated increase in miR-93 levels by upregulating expression NRF2 antioxidant response pathway(11). In 4T1 breast cancer cells in vitamin C-deficient mice, Ascorbic acid delayed the progress of metastasis, tumor growth and inflammatory cytokine secretion (decreased serum inflammatory cytokine interleukin (IL)-6) as well as enhanced encapsulation of tumors(12). In L-ascorbate (L-ascorbic acid, vitamin C), increasing the concentration exhibited the autophagic damage to functional SVCT-2(antibody) sensitizes breast cancer cells(13). In B16F10, L-ascorbate also caused induction of a prooxidant state, subsequent reduction in mitochondrial membrane potential to induced apoptosis in a caspase-8(Cell apoptosis)-independent manner(14). In the usage of glucan, resveratrol and vitamin C, the combination showed the strongest activator of phagocytosis (immune cell activation) and antibody formation to suppress the growth of breast and lung tumors, through stimulation of apoptosis(15). In 4T1 cancer cell line, combined with ascorbate, Mn(III)N-alkylpyridylporphyrins (MnPs) inhibited cancer cells via peroxide produced outside of the cell through enhancing tumour oxidative stress and tumor growth suppression(16). In Ataxia telangiectasia mutated (ATM) diplotype on the breast cancer, vitamin C enhanced the increase of ATM to reduce the risk of breast cancer.(17). In E(2) metabolism and oxidant stress in involved in estrogen-induced breast cancer development, vitamin C reducesd the incidence of estrogen-induced mammary tumors, increased tumor latency and decreases oxidative stress in vivo(18). In SK-BR3 and Hs578T breast cancer cell lines, Vitamin C treatment induced AIF(apoptosis-inducing factor) mediation of cell death pathway of the breast cancer cell lines independent to caspase pathway(19).
In human breast cancer cell line MCF-7, combination of Retinoic acid and ascorbic acid inhibited the proliferation of human breast cancer cells through altering their gene expression related to antioxidation processes and the proliferation inhibitory pathway(20).
Taking all together, without going into reviews, vitamin C is found to be effective in reduced risk and a potent agent for treatment of breast cancer. Daily ingestion of high-dose vitamin C may be considered safe, but in rare incidence, overdoses in a prolonged period of time, may cause intra-renal oxalate crystal deposition, a fatal nephrotoxicity(21)(22).

Phytochemical Piperine and Immunity
Piperine is a phytochemical alkaloid in the class of organosulfur compound, found abundantly in white and black pepper, long pepper, etc.
The immune system is the set of cells and their activity against antigens or infectious agents that comprises of the body's defense system against diseases. The immune system does a great job of keeping people healthy and preventing infections. Beside foods and nutritional supplements, herbs also play a important role in helping the immune system defend against viruses and bacteria attacks.
The effects
Ethanolic extract of fruits of Piper longum L.(PLE) and piperine was found to inhibit the lethal action of venom both in the in vitro lethality neutralization assay and in vivo lethality neutralization assay against Russell's viper venom in mice by enhancing production of antigen and antibodies response.
In the study of the same subject, administration of PLE and piperine significantly (p<0.01) inhibited venom induced lethality, haemorrhage, necrosis, defibrinogenation and inflammatory paw edema in mice in a dose dependent manner, reduced venom induced mast cell degranulation in rats.

Phytochemical Allicin and hyper cholesterol
Allicin is phytochemical containing sulfur in the class of organosulfur compound, found abundantly in onion and garlic.
Cholesterol is needed for our body to build cell walls, make hormones and vitamin D, and create bile salts that help you digest fat. However too much of it can be dangerous because cholesterol cannot dissolve in your blood. The special particle called lipoprotein moves this waxy, soft substance from place to place. If you have too much low density lipoprotein LDL that is known as bad cholesterol, overtime cholesterol can build up in your arterial walls causing blockage and leading to heart attack and stroke.
The health benefits
Evidences emerging that allicin may not only benefit in preventing and treating cardiovascular disease but also lower the blood cholesterol. In the study of the effect of allicin on hypercholesterolemia in male ICR mice, the chemical constituent of garlic showed a positive effect not in reducing blood cholesterol, triglycerides, and glucose levels , as well as lowering the hepatic cholesterol storage, but also decreasing appetite daily. Other in the study of the same but woth rat fed with high cholesterol diet, showed a reduction of blood cholesterol, triglycerides levels and systolic blood pressure in hypercholesterolemic rats. These result showed that allicin may be considered as a potent agent in treating hypercholesterol in the future.
