Expression of genes related to the regulation of muscle protein turnover in Angus and Nellore bulls1 (original) (raw)

2016, Journal of Animal Science

AI-generated Abstract

The study investigates the expression of genes involved in muscle protein turnover (MPT) in Angus and Nellore bulls, focusing on 13 genes linked to the IGF-1 and myostatin pathways. A factorial design was employed, with varying feeding levels impacting gene expression. Significant findings included increased expression of IGF-1 receptor, MuRF1, and Smad3 under feed restriction conditions, while correlations between gene expression and performance traits were analyzed, suggesting potential genetic factors influencing muscle growth.
