Cruciferous vegetables may be considered as the next plants, processing pharmaceutical value in the extraction of single-ingredient chemo medicine of blocking the onset of prostate cancer, some scientists suggested
Prostate cancer is a condition characterized by irregular and uncontrollable growth of the cells of the prostate. In the advanced stage, the cancerous cells can spread to distant parts of the body through blood and fluid circulation.
Most prostate cancers are slow-growing and enlarged prostate and prostate cancer may be detected during physical (rectum) exams.
According to a statistic provided by the Canadian government, 1 in 7 men will develop prostate cancer during their lifetime, and 1 in 27 will die of it.
Sadly, out of 4 men diagnosed with prostate cancer, 1 will die of it. which is very similar to the ratio observed for breast cancer in women.
A diagnosis of prostate cancer carries a significant burden of induction of significant anxiety and depression.
Researchers do not know the exact causes of prostate cancer and can not explain why some men who do process inherited gene mutation are susceptible to the onset of prostate cancer while others do not.
But they do know that some risk factors such as age, family history, race, and diet are associated with the development of prostate cancer.
Early-diagnosed prostate cancer patients have a 5-year survival rate of nearly 100% with 98% of these patients still alive after 10 years compared to the 5-year survival rate of the advanced stage of 30%.
Therefore, if you are at a high risk of the prostate cancer development group, please make sure that you have your prostate gland checked every year.
Cruciferous vegetables are a group of vegetables including cauliflower, cabbage, cress, bok choy,..... and broccoli.
Broccoli is a mustard/cabbage plant, belongings to the family Brassicaceae.
The healthy veggie has large flower heads, usually green in color and a mass of flower heads, surrounded by leaves and evolved from a wild cabbage plant on the continent of Europe.
Epidemiologically, chemical constituents of cruciferous vegetables, such as broccoli have been shown to decrease the incidence of prostate cancer.
In the finding of broccoli effect in the genetic implication of risk of prostate cancer, researchers at the Institute of Food Research conducted a study that includes
volunteers with or without genetic mutation of glutathione S-transferase mu 1 (GSTM1) positive and null.
Glutathione S-transferase (GST) is a detox enzyme with a function involving the detoxification of many potentially carcinogenic compounds.
Participants were randomly assigned to six months of either a broccoli-rich or a pea-rich diet.
At the end of the study, researchers found that
* Pea-rich diet shows no differences in gene expression between glutathione S-transferase mu 1 (GSTM1) positive and null individuals
* Broccoli-rich diet group exerts significant differences between GSTM1 genotypes associated with transforming growth factor beta 1 (TGFbeta1) and epidermal growth factor (EGF) signaling pathways.
* Both diets demonstrate significant androgen signaling.
* Men on the broccoli diet had additional changes to mRNA processing, and TGFbeta1, EGF, and insulin signaling.
The growth factor beta (TGFbeta) signaling pathway is a key role in tumor suppression through modulating processes such as cell invasion, immune regulation, and microenvironment modification normally. However, the transforming growth factor-beta (TGF-beta) signaling pathway can cause tumor development with similar physio activity.
In healthy and malignant cells, epidermal growth factor receptor (EGFR) allows cells to grow and divide
These results suggested that broccoli interacts processed a strong anti-prostate cancer effect in patients with the GSTM1 genotype associated with inflammation and carcinogenesis in the prostate gland.
Dr. Traka M, the lead author after taking into account other factors, said, "Diets rich in cruciferous vegetables may reduce the risk of prostate cancer and another chronic disease".
Furthermore, in a population-based, case-control study of prostate cancer, including 428 men with incident prostate cancer and 537 community controls with genotyping for deletions in GSTM1 and GSTT1 performed in a subset of men who provided blood, researchers found that
* Intake of cruciferous vegetables, such as broccoli, the greatest source of sulforaphane, is associated with decreased prostate cancer risk at all levels compared to the lowest consumers.
* Intake of cruciferous vegetables also displays a significantly reduced risk of prostate cancer in men with a mutation of gene GSTM1. Particularly in the high broccoli intake group.
The finding suggested that 2 or more servings per month of cruciferous vegetables may reduce the risk of prostate cancer, especially among men with GSTM1-present alleles.
At the final of the experimental report, Dr. Joseph MA, the lead scientist, wrote, "(These results) are consistent with a role of dietary ITCs as chemopreventive agents against prostate cancer.
The depletion of the gene of the GSTM1 genotype of Glutathione S-transferase (GST) enzymes may be associated with an increased risk of cancer as this depletion reduced the function of GST in detoxifying most potentially carcinogenic compounds.
Taken altogether, cruciferous vegetables may be considered as a functional food in the promoted expression of detoxified enzymes to prevent the onset of prostate cancer, especially in men with the genetic mutation gene GSTM1.
