Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Transient receptor potential melastatin 7 (TRPM7), a magnesium (Mg) -regulated chanzyme possessing both ion channel and kinase activities, has a much stronger affinity to Mg2+ than calcium (Ca)2+. We previously reported that individuals with the TRPM7 GA/AA genotype and consumed diets high in Ca:Mg ratio had an increased risk of colorectal polyps. The TRPM7 gene was also observed to possess "driver" mutations that contribute to developing multiple cancers. However, the molecular mechanism remains unclear. To identify if the gut microbiota plays a role in this association, we will investigate whether optimizing Ca:Mg intake ratios to 2.3 altered the abundance of the microbes (e.g. associated with TRPM7 genotype and the risk of metachronous polyps) at the genus level in at least one sample type among stool, swab and tissue in a double-blind 2x2 factorial (TRPM7 genotype and Ca:Mg ratios) randomized trial (Personalized Prevention of Colorectal Cancer Trial, NCT01105169).
