LPCAT1 and posterior cortical atrophy: They showed that, when fecal microbiota transplant (FMT) derived from men with castrate-resistant prostate cancer (CRPC) were transferred to the transgenic adenocarcinoma of the mice prostate (TRAMP), high levels of gut Ruminococcus was induced and concomitantly PCa growth increased, probably due to the increase in lysophosphatidylcholine acyltransferase 1 (LPCAT1) (since Ruminococcus is correlated with phospholipid metabolism), given that its upregulation has been described in several types of cancers and is associated with a poor prognosis [124,125,126].
