Effects of FSH treatment and withdrawal during proestrus on uterine proliferation and steroid hormone receptor expression in beef heifers.

abstract：:Muscle-fiber type in livestock skeletal muscles influences meat quality, but the underlying mechanisms remain unclear. We previously showed that Homeobox A11 (Hoxa11) and Homeobox A13 (Hoxa13) are differentially expressed in fast- and slow-twitch muscles, but their effects on the formation of muscle-fiber types and in...
