Danggui Sini decoction alleviates oxaliplatin-induced peripheral neuropathy by regulating gut microbiota and potentially relieving neuroinflammation related metabolic disorder.

Background: Danggui Sini decoction (DSD), a traditional Chinese medicine formula, has the function of nourishing blood, warming meridians, and unblocking collaterals. Our clinical and animal studies had shown that DSD can effectively protect against oxaliplatin (OXA)-induced peripheral neuropathy (OIPN), but the detailed mechanisms remain uncertain. Multiple studies have confirmed that gut microbiota plays a crucial role in the development of OIPN.

GALNT3 protects against vascular calcification by reducing oxidative stress and apoptosis of smooth muscle cells.

Vascular calcification (VC) is the pathological deposition of calcium and phosphate minerals in blood vessels, which is a common complication of atherosclerosis. Polypeptide N-acetylgalactosamine transferase 3 (GALNT3) initiates O-glycosylation of proteins through addition of GalNAc to specific serine or threonine residues. Our previous studies revealed the potent role of GALNT3 in atherosclerosis, whereas the precise mechanisms remain obscure.
