  • EFFECT OF LIGUSTRAZINE ON EXPRESSIONS OF FoXO3a, MAFbx, AND MuRF1 IN DENERVATED SKELETALMUSCLE ATROPHY RATS/

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