Bacterial Synthesis of p-Aminobenzoic Acid.

open access: yesExperimental Biology and Medicine, 1943
SummaryRepresentative cultures of many bacterial genera were grown in culture media of known composition free of p-aminobenzoic acid. Culture filtrates and hydrolized whole cultures were assayed for p-aminobenzoic acid content employing the Acetobacter suboxydans microbiological method.

Gut Metabolite Indole‐3‐Propionic Acid Regulates Macrophage Autophagy Through PPT1 Inhibiting Aging‐Related Myocardial Fibrosis

open access: yesAdvanced Science, EarlyView.
IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...
