TNF-α mediated the upregulation of p-STAT3 following L5-VRT. a The upregulation of p-STAT3 was induced by L5-VRT. n = 5 per group, **P < 0.01 versus the sham group. b Representative blots and histogram showed the effect of thalidomide on the p-STAT3 upregulation in the rats with L5-VRT. n = 5 per group, **P < 0.01 versus the sham group, ##P < 0.01 versus the corresponding L5-VRT group. c The immunofluorescence staining showed the colocalization of TNF-α with p-STAT3. n = 3 per group, Scale bar, 50 μm
