Microbiome‑Gerogene Axis Links Gut Health to Cellular Longevity
A new review in Frontiers in Aging outlines a microbiome‑gerogene axis, positioning gut microbes as upstream regulators of cellular aging. Age‑related dysbiosis cuts production of key metabolites, leading to leaky gut, chronic inflammation and epigenetic drift that accelerate organ decline. The authors suggest precision interventions such as ellagitannin‑derived urolithin A and fermentable fibers to restore microbial balance.
Research Reveals Exactly How Everyday Chemicals Disrupt Your Hormones
A recent study in Basic & Clinical Pharmacology & Toxicology uncovers a PXR‑SHBG‑testosterone pathway that explains how common chemicals alter hormone balance. In a week‑long rifampicin trial, participants’ SHBG levels doubled, raising total testosterone but reducing biologically active testosterone and lowering thyroid hormones in men. The researchers link this effect to everyday PXR‑activating substances found in pesticides, flame retardants and plastic additives. The finding offers a concrete mechanism for the endocrine‑disrupting properties of everyday plastics.
