Vitamin a can prevent the spread of prostate cancerA new study confirmed that vitamin a can help in the treatment and prevention of the spread of prostate cancer. Scientists have discovered that carrots, green vegetables and liver-derived retinoic acid can reverse prostate cancer stem cell-specific genes, the ability to reduce cancer invade surrounding tissue.It is well-known that prostate cancer is the male prostate tissue cancer, prostate acinar cells abnormal growth disorder. The incidence of prostate cancer has obvious geographical and ethnic differences. The exact cause of prostate cancer has not yet been clear, may be associated with genetic changes. Changes in the androgen receptor gene lead to increased risk for prostate cancer, BRCA1 gene men suffering from prostate cancer, the risk is no BRCA1 gene men three times; exception of the P53 gene and high-level, high-invasion of prostate cancer are closely related. The genetic changes may also be related to diet and other environmental factors. More genetic changes, the greater the risk of prostate cancer. In a few cases, prostate cancer may be hereditary.The results show that the vitamin a is related compounds can be used to improve the clinical effect of treatment of prostate cancer. YCR Cancer Research Unit, Department of Biology, experts said that cancer arises from abnormal development of healthy cells. Some controls is turned off to allow cancer progression uncontrolled growth and the ability to invade surrounding tissue, such as normal cells. Researchers have found that the use of retinoic acid can turn off a lot of the malignant prostate cancer stem cells twin genes, cancer becomes less aggressive.All-trans retinoic acid is used to treat other types of cancer such as acute leukemia, a drug to improve survival and achieved great success. For prostate cancer, our work has shown that retinoic acid does not kill cancer stem cell
