Objective To investigate the effect of Ligustrazine on the expressions of FoXO3a, MAFbx, and MuRF1 in
denervated skeletal muscle atrophy rats. Methods Fifty-four 8-week-old female Sprague Dawley rats were randomly divided
into 3 groups: normal control group (group A, n=6), denervated control group (group B, n=24), and Ligustrazine intervention
group (group C, n=24). After the denervated gastrocnemius models were established in the rats of groups B and C, sal ine and
Ligustrazine [80 mg/(kg·d)] were given every day by intraperitoneal injection, respectively. However, no treatment was done
in group A. At 2, 7, 14, and 28 days after denervation, the wet weight of gastrocnemius was measured to calculate the ratio of
wet weight. The mRNA and protein expression levels of FoXO3a, MAFbx, and MuRF1 were detected by RT-PCR and Western
blot. Results The ratio of gastrocnemius wet weight decreased with time after denervation in groups B and C, showing
significant differences when compared with that of group A (P  lt; 0.05), and group C were significantly higher than that of group
B at 7, 14, and 28 days (P  lt; 0.05). The mRNA and protein expressions of FoXO3a, MAFbx, and MuRF1 in groups B and C
were significantly higher than those in group C at 7, 14, and 28 days (P  lt; 0.05), and group C was significantly lower than group
B (P  lt; 0.05). Conclusion Ligustrazine may postpone denervated skeletal muscle atrophy by reducing mRNA and protein
expressions of FoXO3a, MAFbx, and MuRF1.
