Gene-regulator Therapy Could Help Keep Prostate Cancer from Spreading, Study Says
Researchers have pinpointed a naturally occurring molecule that limits the invasive capacity of prostate cancer, suggesting that treating patients with a man-made version of the factor could prevent the cancer from spreading. The study, MicroRNA-141 suppresses prostate cancer stem cells and metastasis by targeting a cohort of pro-metastasis genes,” was published in the journal Nature Communications. The molecule, miR-141, is a microRNA (miRNA) that helps control gene activity. To learn more about processes that govern the cancer’s ability to spread, or mestastacize, researchers at Roswell Park Cancer Institute screened for miRNA activity in prostate cancer stem cells. They used both animals and humans in their work. To their surprise, they found only a few miRNAs in lower levels than normal. When they manipulated the cells to produce more of the missing factors, miR-141 was the only one that could prevent cancer growth. Testing the molecule in a number of prostate cancer models, the team showed the factor also prevented metastases. Earlier studies have yielded conflicting findings about whether the miRNA family to which miR-141 belongs have anticancer and antimetastatic properties. Some research showed it did, but others indicated it actually promotes metastasis in certain cancers. The Roswell Park researchers explored miRNAs in cancer stem cells, which constitute only a small proportion of the cells in a tumor. That led them to hypothesize that the different results in earlier studies may mirror differences in cell characteristics. "This study re

    I dont know about this therapy but I will for sure research more info about it; I believe natural treatmens are better. I have been dealing with prostate problems for a couple of years, I am on my 50s already so I guess it’s pretty normal, I spent many time on internet researching for ways to cure it and I tried many things but it was so frustrating because they didnt help me, my urologist recommended me some medicaments and I tried some but it was such a waste of money I gave up, I was frustrated until my friend told me about his experience and how a natural supplement named alpharise helped him so I decided to try it and its really good, it helped me so much, I am happy with the results now i am trying to complement it with a healthy alimentation and avoiding alcohol and smoking.
