Cleveland Clinic research study links gut microbiome and aggressive prostate cancer.
Cleveland Clinic scientists have actually revealed for the very first time that diet-associated particles in the gut are related to aggressive prostate cancer, recommending dietary interventions might help in reducing threat. Findings from the research study were released in Cancer Epidemiology, Biomarkers & &Prevention
(******************************************************* )more research study will be needed, the research study’s lead author Nima Sharifi, M.D., states findings from the group’s analysis of almost 700 clients might have scientific ramifications for identifying and avoiding deadly prostate cancer.
“We found that men with higher levels of certain diet-related molecules are more likely to develop aggressive prostate cancer,” statedDr Sharifi, director of Cleveland Clinic’s Genitourinary Malignancies ResearchCenter “As we continue our research in this area, our hope is that one day these molecules can be used as early biomarkers of prostate cancer and help identify patients who can modify their disease risk by making dietary and lifestyle changes.”
In this research study,Dr Sharifi and his partners– consisting of Stanley Hazen, M.D.,Ph D., and Eric Klein, M.D.– evaluated information from clients formerly registered in the National Cancer Institute’s Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial.
They studied standard levels of specific dietary nutrients and metabolites (by-products produced when a compound is broken down in the gut) discovered in clients’ blood serum prior to prostate cancer medical diagnosis. They compared serum levels in between healthy clients and those who later on got a prostate cancer medical diagnosis and passed away from the illness.
The scientists discovered that males with raised levels of a metabolite called phenylacetylglutamine (PAGln) were roughly 2 or 3 times most likely to be identified with deadly prostate cancer. This metabolite is produced when microorganisms in the gut break down phenylalanine, an amino acid discovered in numerous plant- and animal-based protein sources like meat, beans, and soy.
In addition to PAGln, scientists likewise found that raised levels of 2 nutrients plentiful in animal items, consisting of red meat, egg yolks, and high-fat dairy items, called choline and betaine, likewise were related to increased threat for aggressive prostate cancer.
While these nutrients and gut metabolites have actually been studied formerly in heart problem and stroke, this is the very first time that gut microbiome metabolites have actually been studied medically in relation to prostate cancer results.
Dr Hazen was the very first to determine PAGln’s association with increased heart disease threat. The findings were released in 2020 in Cell “Interestingly, we found that PAGln binds to the same receptors as beta blockers, which are drugs commonly prescribed to help lower blood pressure and subsequent risk of cardiac events,” statedDr Hazen, director of Cleveland Clinic’s Center for Microbiome & &(****************************************************************************************************** )(********************************************************************************************************* )and chair of Lerner Research Institute’s Department of Cardiovascular & &(************************************************************************************** )Sciences“This suggests that part of beta blockers’ potent efficacy may be due to blocking the metabolite’s activity.”
“New insights are emerging from large-scale clinical datasets that show use of beta blockers is also associated with lower mortality due to prostate cancer,” statedDr(**************************************************************** )who is a personnel doctor inLerner(********************************************************************* )Institute’s Department of CancerBiology “We will continue to work together to investigate the possible mechanisms linking PAGln activity and prostate cancer disease processes in hopes of identifying new therapeutic targets for our patients.”
The research study group likewise will continue to check out the dependability of utilizing choline, betaine and PAGln as biomarkers of aggressive prostate cancer and how dietary interventions can be utilized to regulate their levels and lower clients’ subsequent illness threat.
