[MAFbx and MuRF1 mRNA expression and its relationship with muscular contractility following free muscle transfer].

Objective: To study muscle atrophy F-box (MAFbx) and muscle ring finger 1 (MuRF1) mRNA expression and its relationship with muscular contraction following free muscle transfer.

Methods: The gracilis muscle was orthotopic transferred in adult rat to establish the animal model. The muscle at the unoperated side was used as control.
