3-(4-Hydroxy-3-methoxyphenyl) propionic acid mitigates dexamethasone-induced muscle atrophy by attenuating Atrogin-1 and MuRF-1 expression in mouse C2C12 skeletal myotubes.

ABSTRACT: 3-(4-Hydroxy-3-methoxyphenyl) propionic acid is an in vivo metabolite of 4-hydroxy-3-methoxycinnamic acid which is abundantly found in coffee bean, rice bran, fruits, and vegetables. Previous studies reported that polyphenols and their metabolites exhibit positive effects on muscle health. Thus, the effect of 3-(4-hydroxy-3-methoxyphenyl) propionic acid on muscle atrophy induced by dexamethasone was investigated using mouse C2C12 skeletal myotubes. Dexamethasone treatment (10 ‍μM) reduced the diameter and myosin heavy chain protein expression in C2C12 myotubes; it also increased muscle atrophy-associated ubiquitin ligases, such as muscle atrophy F-box protein 1/Atrogin-1 and muscle ring finger protein-1, along with their upstream regulator Krüppel-like factor 15.
