Fig. 7From: Local application of rapamycin reduces epidural fibrosis after laminectomy via inhibiting fibroblast proliferation and prompting apoptosisThe expression levels of cleaved-PARP, Bax, and Bcl-2 in fibroblasts after treatment with different concentrations of RAPA (0.01 μg/ml, 0.1 μg/ml, and 1 μg/ml) for 48 h. When the dose of RAPA increased, the levels of the pro-apoptotic proteins cleaved-PARP and Bax increased; however, the levels of the anti-apoptotic protein Bcl-2 decreasedBack to article page
