Ovarian Cancer in B12 Points of View

  Kyle J. Norton

Ovarian cancer is defined as a condition of  abnormal cells growth of ovaries  It is one of most common cancer in US, according to the statistics adapted from the American Cancer Society's publication, Cancer Facts & Figures 2010, an estimated 21,880 women in the United States were diagnosed with ovarian cancer and 13,850 deaths.
Depending to the stage and grade of the cancer, chemotherapy such as cisplatin, carboplatin, paclitaxel, liposomal doxorubicin may be necessary to prevent the spread and recurrence of the cancer. Epidemiological studies focusing in vegetables and fruits in reduced risk and treatment of ovarian cancer have not been conclusive(a)(b)(c)(d), some vitamins have showed to inhibit the progression of cancer with little or no side effects.

Vitamin B12, also known as cobalamin, a water-soluble vitamin, found abundantly in a variety of foods, such as fish, shellfish, meat, eggs, dairy products, etc. plays an important role in regulating the functions of nervous system and formation of blood.

Epidemiological studies, linking vitamin B12 in reduced risk of ovarian cancer have drawn into inconclusive results. Suggestion of Folate, methionine, vitamin B(6) and vitamin B(12) may influence carcinogenesis due to their roles in the one-carbon metabolism pathway. In a study among 1910 women with ovarian cancer and 1989 controls from a case-control study conducted in eastern Massachusetts and New Hampshire from 1992 to 2008, have indicated that One-carbon metabolism(metabolic network of interdependent biosynthetic pathways) related nutrients,  may lower ovarian cancer risk(1). Nitrosylcobalamin (NO-Cbl), a chemotherapeutic pro-drug derived from vitamin B12 has been found effectively in antiproliferative activity against several human cancer cell lines, including ovarian carcinoma (NIH-OVCAR-3) cells, through induction of apoptosis via a death receptor/caspase-8 pathway(2). In patients with epithelial ovarian cancer under treatment of Paclitaxel (T) and Carboplatin (J) combination chemotherapy, vitamin B12 was effective in relieving symptoms of arthralgia and muscular pain(3).

Taking altogether, vitamin B12 may be effective in reduced riak and treatment of ovarian cancer, but large sample and multu centers studies to validate its effects are necessary. As always, all articles written by Kyle J. Norton are for information & education only, please consult your Doctor & Related field specialist before applying. Over doses of the vitamin may induce symptoms of toxicity, including headache, giddiness and abnormal heart functioning, etc., please make sure to follow the guideline of the Institute of Medicine of the National Academies.

Ovarian Cancer in Folate Points of View

 Kyle J. Norton

Ovarian cancer is defined as a condition of  abnormal cells growth of ovaries,  It is one of most common cancer in US, according to the statistics adapted from the American Cancer Society's publication, Cancer Facts & Figures 2010, an estimated 21,880 women in the United States were diagnosed with ovarian cancer and 13,850 deaths.
Depending to the stage and grade of the cancer, chemotherapy such as cisplatin, carboplatin, paclitaxel, liposomal doxorubicin may be necessary to prevent the spread and recurrence of the cancer. Epidemiological studies focusing in vegetables and fruits in reduced risk and treatment of ovarian cancer have not been conclusive(a)(b)(c)(d), some herbs have showed to inhibit the progression of cancer with little or no side effects.
Folate, also known as folic acid, vitamin B9, is a water soluble vitamin, found abundantly in leafy vegetables, citrus fruits, beans, whole grain, etc. The vitamin plays an important role in synthesize DNA, repair DNA, and methylate DNA as well as to act as a cofactor in certain biological reactions, production of red blood cells for anemia prevention.

Epidemiological studies, focusing folate in reduced risk of ovarian cancer have been inconclusive.
Folate, a member of B vitamin plays an important role in DNA synthesis and methylation, may process an anti proliferative effect in ovarain cancer cell lines. The Australian Ovarian Cancer Study (1363 cases, 1414 controls) self-completed risk factor and food-frequency questionnaires, showed a little evidence to support the effect of folate in reduced risk of ovarian cancer(1) and  ovarian cancer survival(2). Other researchers suggested that no specific dietary factors are consistently associated with ovarian cancer risk, including folate(3), neither folate intake, MTHFR C677T polymorphism(4) nor one-carbon metabolism(5)
A prospective case-control study of the effect of Folic acid and methylenetetrahydrofolate reductase (MTHFR) against ovarian cancers in 215 ovarian cancer patients and 218 controls (all Chinese) between Jan. 2004 and Jan. 2007, indicated a result of a 2.43-fold increased risk of ovarian cancer among MTHFR 677TT carriers, and a decreased risk of ovarian cancer in individuals with high folate intake(6). Intravenous administration of composition of  FA-NP showed more potent in anti proliferation than NP against both SKOV3 cells and SKOV3/TAX cells, but at the same dose failed to induce apoptosis and inhibit tumor nodule number. Of these results, researchers suggested that the combined use of both FN-NP locally and targetly might prolong the survival time in patients with drug-resistant ovarian cancer(6). The Brigham and Women's Hospital study also supported the evidence of one-carbon metabolism related nutrients, especially vitamin B(7) and methionine inlowering ovarian cancer risk, with a 1910 women with ovarian cancer and 1989 controls from a case-control study conducted in eastern Massachusetts and New Hampshire from 1992 to 2008(8).

Taking all together, there are either enough evidences supported or unsupported  the effectiveness of folate in reduced risk of ovarian cancer. Further studies with large sample size and mutli centers studies are necessary to clarify the effect of folate in ovarian cancer risk. At the mean time as always, all articles written by Kyle J.

Ovarian Cancer in Vitamin B6 Points of View

 Kyle J. Norton

Ovarian cancer is defined as a condition of  abnormal cells growth of ovaries. It is one of most common cancer in US, according to the statistics adapted from the American Cancer Society's publication, Cancer Facts & Figures 2010, an estimated 21,880 women in the United States will be diagnosed with ovarian cancer and 13,850 deaths.

Depending to the stage and grade of the cancer, chemotherapy such as cisplatin, carboplatin, paclitaxel, liposomal doxorubicin may be necessary to prevent the spread and recurrence of the cancer. Epidemiological studies focusing in vegetables and fruits in reduced risk and treatment of ovarian cancer have not been conclusive(a)(b)(c)(d), some vitamins have showed to inhibit the progression of cancer with little or no side effects.
Vitamin B6, also known as pyridoxine, is a water soluble vitamin found abundantly in green peas, yams, broccoli, asparagus and turnip greens,Peanuts, sunflower seeds, cashews and hazelnuts, meat, fish etc., with functions of amino acid, carbohydrate  metabolism, brain health, and liver detoxification, etc.

Epidemiological studies, linking vitamin B6 in reduced risk of ovarian cancer have been inconsistent. 
The study of the Brigham and Women's Hospital, Boston, indicated that intake of one-carbon metabolism related nutrients, especially vitamin B(6) and methionine, may lower ovarian cancer risk (1). In 80,254 Nurses' Health Study participants, during 22 years of follow-up (1980-2002), researchers found little evidence to support dietary folate, methionine, and vitamin B(6) in related ovarian cancer risk(2), But
in the study to compare the effectiveness of acupuncture plus vitamin B6 PC6 points injection of 142 patients, between March 1, 2006, and June 30, 2008 indicated that acupuncture plus vitamin B6 PC6 points injection relieved nausea and vomiting in patients with ovarian cancer, undergoing a highly emetogenic chemotherapy regimen(3). In a  total of 248 analyzable patients with Stages III-IV ovarian epithelial cancer (114 with and 134 without prior chemotherapy) conducted by the Albert Einstein Cancer Center, showed that although  administration of pyridoxine significantly reduced neurotoxicity, its adverse effect on response duration suggests that the agent should not be administered with  cisplatin (DDP) and hexamethylmelamine (HMM) regimens(4). In the assessed dietary intakes and factors associated with diet in women with family history of breast and/or ovarian cancer (FHBOC) study, suggest that women with FHBOC should be encouraged to meet dietary guidelines for cancer prevention, including intake of vitamin B6(5).

Taking altogether, vitamin B6 may be associated to reduced risk and treatment of ovarian cancer when it is used in conjunction with acupuncture, but further study with large sample and multi center studies are necessary to improve the validation. Over doses may induced the symptoms of difficulty coordinating movement, numbness, sensory changes, etc., please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Ovarian Cancer in Vitamin K Points of View

 Kyle J. Norton
Ovarian cancer is defined as a condition of  abnormal ovarian cells growth of ovaries,  It is one of most common cancer in US, according to the statistics adapted from the American Cancer Society's publication, Cancer Facts & Figures 2010, an estimated 21,880 women in the United States will be diagnosed with ovarian cancer and 13,850 deaths.
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.

Researchers at the Showa University indicated that vitamin K may process the anti wide array of human cancer cell lines properties through differentiation and apoptosis(1). DR. Shibayama-Imazu, the leader of the research team said that these inductions may be through interruption of the morphological changes and DNA fragmentation via the loss of mitochondrial membrane potential (DeltaPsim caused by superoxide(1).  Vitamin K2 also induced apoptosis of human ovary cancer cells (TYK-nu cells), through the process of production of superoxide, induced oxidative stress in mitochondria might damage mitochondrial membranes(2). In PA-1 ovarian cancer cells, vitamin exhibited apoptosis through increased in the synthesis of TR3 and the accumulation of TR3 in mitochondria and in nuclei via a JNK signaling pathway(3). Against human ovarian carcinoma cell line (MDAH 2774), the composition of VC (ascorbic acid) and VK3 (menadione), inhibited cell proliferation through DNA degradation(4) and exposure to the composition also expressed the anti proliferation of cell death through autoschizis (43%), apoptosis (3%), and oncosis (1.9%)(5). In the comparison of the effect of vitamin K(2) (menaquinone 4) and  geranylgeraniol (GGO)inhuman cancer cell line, showed that GGO inhibited the growth of all eight cell lines derived from solid tumors, while vitamin K(2) selectively inhibited the proliferation and induced apoptosis in both ovarian cell lines(6). Study of the cytotoxic effect and mechanism of action of vitamins C (VC) and K3 (VK3) on ovarian carcinoma, indicated a positive effects of the composition in induced cell death  (displayed characteristics of both apoptosis and necrosis), through cycle arrest and degradation of chromosomal DNA(7).

Taking all together, vitamin VK2 and VK3 are found effectively in reduced risk and treatment of ovarian cancer through activation of cell death mechanism, via activation of RSO, cell cycle arrest,  and inhibition of cell proliferation via degradation of DNA. Large sample and multi centers studies to validate this effectiveness are necessary. 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

Ovarian Cancer in Vitamin E Points of View


By Kyle J. Norton

Ovarian cancer is defined as a condition of  abnormal ovarian cells growth of ovarian cells,  It is one of most common cancer in US. According to the statistics adapted from the American Cancer Society's publication, Cancer Facts & Figures 2010, an estimated 21,880 women in the United States were diagnosed with ovarian cancer and 13,850 deaths.

Depending to the stage and grade of the cancer, chemotherapy such as cisplatin, carboplatin, paclitaxel, liposomal doxorubicin may be necessary to prevent the spread and recurrence of the cancer. Epidemiological studies focusing in vegetables and fruits in reduced risk and treatment of ovarian cancer have not been conclusive(a)(b)(c)(d), some herbs have showed to inhibit the progression of cancer with little or no side effects.

 Vitamin E,  a fat soluble vitamin, consisting eight different variants (alpha-, beta-, gamma-, and delta-tocopherol and alpha-, beta-, gamma-, and delta-tocotrienol) with varying levels of biological activity(2), found abundantly in corn oil, soybean oil, margarine, wheat germ oil, sunflower,safflower oils, etc. plays an important role in neurological functions and inhibition of platelet aggregation, regulation of enzymatic activity, free radical scavenger, etc.

Epidemiological studies, linking serum of vitamin E in the risk of ovarian cancer have produced inconsistent results.  Serum levels of vitamin are not associated to ovarian cancer risk, according to Tampere University Central Hospital and (1) but the study by Johns Hopkins University School of Hygiene and Public Health, indicated that the higher serum alpha-tocopherol levels are associated with an increased risk of ovarian cancer but diminished after adjustment for cholesterol(2). Other study suggested that lower alpha-tocopherol concentrations may be associated with the toxicity of  chemotherapy(3).

Alpha-TEA , a novel vitamin E analogue found to induce apoptosis a wide variety of epithelial cancer cell types, including breast, prostate, lung, colon, ovarian, cervical, and endometrial in cell culture and inhibit tumor burden and metastasis in a syngeneic mouse mammary tumor model,(4). Other study suggested that vitamin E derivative, vitamin E succinate (VES; RRR-alpha-tocopheryl succinate), and a vitamin E analogue alpha-TEA can induce A2780 and subline A2780/cp70 ovarian cancer cells to undergo DNA synthesis arrest within 24 h of treatment, excluding normal human mammary epithelial cells(5). In SK-OV-3 human ovarian adenocarcinoma along with its multi-drug resistant version SK-OV-3-paclitaxel-resistant (TR) cells, combination treatment of vitamin E co-loaded with curcumin and paclitaxel(a mitotic inhibitor) exhibited  a three-fold tumor inhibition with each of these cell lines(6). According to the University of Strathclyde, intravenous administration tocotrienol-rich fraction (TRF), showed to exhibit tumor regression and improved animal survival in a murine xenograft model(7). In MDAH2774 human ovarian cancer cells combined treatment of Adenovirus-mediated mda-7 (Ad-mda7) plus VES inhibited tumor progression through activation of two apoptotic extrinsic and intrinsic pathways (specifically Fas expression and cleavage of Bid and caspase-8 and disruption of mitochondrial in activation of downstream capase-9 and caspase-3 via cytochrome C releasE) but not the normal fibroblasts(8). and treatment with Ad-mda7-mediated alone induced apoptosis of  human ovarian cancer cells via activation of the Fas-FasL signaling pathway(9).

Taking altogether,  vitamin E succinate and analogue may be effective in reduced risk and treatment of ovarian cancer. Large sample size and multi center studies to validate the claims are necessary. Over doses of vitamin E supplement can cause symptoms of blurred vision, weakness, dizziness, nausea, diarrhea, etc., please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Ovarian cancer in vitamin A points of view

Kyle J. Norton
Ovarian cancer is defined as a condition of  abnormal ovarian cells growth of ovaries.  It is one of most common cancer in US,  According to the national cancer institute, in 2013 Us alone, 22,240 women were diagnosed with the incidence of the disease with death of 14030.
Depending to the stage and grade of the cancer, chemotherapy such as cisplatin, carboplatin, paclitaxel, liposomal doxorubicin may be necessary to prevent the spread and recurrence of the cancer. 
Recommended intakes of vitamin A, according to  the Institute of Medicine of the National Academies (formerly National Academy of Sciences) is 600 µg daily as extremely high doses (>9000 mg) can be toxicity as causes of dry, scaly skin, fatigue, nausea, loss of appetite, bone and joint pains, headaches, etc.
Epidemiological studies, linking vitamin A in reduced risk and treatment of ovarian cancer have been inclusive(a)(b)(c)(d)(e)(f).
1. Retinols
According to Temple University School of Medicine, retinols, the natural and synthetic derivatives of vitamin A, showed to inhibit the growth of human ovarian cancer cells both in vivo and in culture, suppressed ovarian carcinoma cell growth and induced apoptosis in ovarian tumor cells(1). All-trans-retinoic acid (ATRA) has shown to inhibit the growth of several ovarian tumor cell lines, other ovarian carcinoma cell lines, and its synthetic version AHPN/CD437 induced apoptosis through at least in part via an RAR(retinoic acid receptor) pathway(2)(3). Other study suggested that a novel combination of ATRA and zoledronic acid significantly induced apoptosis of related cell death in both OVCAR-3 and MDAH-2774 ovarian cancer cell lines with fewer side effects as compared to conventional cytotoxic agents(4).
 Some researchers suggested that ovarian cancer may be as a result of impaired conversion of retinol to RA in ovarian cancer cells and decreased CRBP1(Cellular Retinol Binding Protein 1) protein expression in prophylactic oophorectomies(surgery that reduces risk of breast cancer and ovarian cancer) causing concomitant losses of vitamin A metabolism and CRBP1 expression of which contribute to ovarian oncogenesis(5). Rb2/p130, a  tumor suppressor protein with function in regulation of  cell cycle progression, treatment of ATRA in sensitive ovarian carcinoma CA-OV3 cells, showed a dramatic increase in Rb2/p130 protein mediated growth arrest at G0/G1, but not growth arrest, although with a Rb2/p130 expressed at high levels in SK-OV3 cells(6)(7).

2. Carotenoids(beta-carotene, alpha-carotene, gamma-carotene and beta-cryptoxanthin) Carotenoids, plant pigments, converted to vitamin A after intake, play an important role in prevention and treatment of some diseases through it antioxidant effects. Fenretinide (4-HPR), a synthetic retinoid, showed to induce apoptosis through a signaling cascade starting from reactive oxygen species (ROS) generation and involving endoplasmic reticulum (ER) stress response, inducing apoptosis(8) and may be used as a preventive agent in genetic mutation, such as BRCA-1 and 2 mutation carriers causes of ovarian cancer(9). According to the Medical University of Białystok, in the study of vitamin A variants in association with ovarian cancer risk, among vitamin A family compounds retinol and carotenoids, but not retinoids, inhibited the growth of cancer cells in dose dependent manner on human ovary endometrioid cancer cell line CRL-11731(10). Other researchers suggested to use antioxidants, including vitamin A variants) with first-line chemotherapy in treatment for ovarian cancer. In 2 case of women with ovarian cancer treatment, antioxidants showed to improve the efficacy of chemotherapy when used in conjunction with first-line chemotherapy(11)(12).

Taking altogether, Vitamin A and its variants may be effective in reduced risk and treatment of ovarian cancer, especially when use conjunction with chemotherapy. As always, overdoses can lead to toxic symptoms. Please make sure you follow the guideline of the Institute of Medicine of the National Academies.

Ovarian Cancer in Vitamin D Points of View

Kyle J. Norton

According to the information of national cancer institute, in 2013 Us alone. 22,240 women were diagnosed with the incidence of the disease with death of 14030.
Depending to the stage and grade of the cancer, chemotherapy such as cisplatin, carboplatin, paclitaxel, liposomal doxorubicin may be necessary to prevent the spread and recurrence of the cancer. Epidemiological studies focusing in vegetables and fruits in reduced risk and treatment of ovarian cancer have not been conclusive(a)(b)(c)(d), some herbs have showed to inhibit the progression of cancer with little or no side effects.
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.

1. Serum of vitamin D and genes mutation
Suggestion of epidemiological studies, linking people who live in higher attitude or carry vitamin D receptor VDR rs2228570 and ApaI polymorphism are associated to the incidence of ovarian cancer and related motility rate(1)(2)(3)(4). These may be due to vitamin D deficiency and genes mutation. According to Uniwersytet Mikołaja Kopernika w Toruniu, [1.25(OH)2D3, the active form of vitamin D showed to inhibit cancer cell growth, induced cancer cell maturation, apoptosis, and decreased angiogenesis. People with lower levels of  serum 25-hydroxyvitamin D (25[OH]D) are associated to risk of ovarian cancer development(6)(7), lower overall survival rate and severe deficiency in more aggressive course of ovarian cancer(5). But the Vanderbilt University School of Medicine, in association between circulating 25(OH)D and ovarian cancer risk, in logistic regression models used to estimate odds ratios and 95% confidence intervals among 516 cases and 770 matched controls, do not support an overall association between circulating 25(OH)D and ovarian cancer risk, except possibly among overweight women(8).

The efficacy
Epidemiological studies focusing in vitamin D in reduced risk of ovarian cancer have been inclusive. The study of Brigham and Women's Hospital and Harvard Medical School, in a total of 1,225 incident epithelial ovarian cancer cases (NHS: 970, NHSII: 255) over 4,628,648 person-years of follow-up, indicated no evidence to support intake of vitamin D from food or supplements or predicted 25(OH)D levels are associated to risk of ovarian cancer(9) neither Plasma 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D(10), nor vitamin D supplementation(11).  But according to Dr. Holick MF., Improved vitamin D status is associated to decreased risk for developing several deadly cancers including colon, breast, pancreatic and ovarian cancers(12) and Uniwersytet Mikołaja Kopernika w Toruniu, Vitamin D3 supplementation in moderate doses, many be benefits in decreased risk of developing cancer, including ovarian cancer(13). Some researchers suggested that 1,25-Dihydroxyvitamin D3 suppressed telomerase (a an essential enzyme that counteracts the telomere attrition accompanying DNA replication during cell division) expression and decreased in malignant human ovarian tumors as well as human ovarian cancer cell lines through microRNA(short (20-24 nt) non-coding RNAs are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs.)-498(14)(15). In ovarian epithelial cancers (OCa), 1,25-dihydroxyvitamin D(3) (1,25(OH)(2) VD)(3) induced OCa cell apoptosis through down-regulating telomerase(16). Adding to above findings, The study by University of Hawaii Cancer Center suggested that lifetime vitamin D exposure may be inversely associated with risk of ovarian carcinoma(17).

Taking altogether, serum levels of vitamin D and vitamin D may be associated to reduced risk and treatment of  ovarian cancer, through regulation of genes and suppression telomerase expression. 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.
