The expression changes of the BCL-2 family members after treatment with BDNFin NB cells. TB3 and TB8cells were treated with BDNF (100 ng/ml), and then cells were harvested at different time points, and Western blot was done to identify the expressions of BCL2 family members in protein level (a). b The expressions of PUMA, NOXA, MCL, and BCL-XL in mRNA level (treated with BDNF for 2 h) were tested by real-time PCR representatively. Bars, SD P-value were tested by Student’s t test. **P < 0.01
