Fig. 4. Corylin induced the expression of lncRNA RAD51-AS1 to downregulate the RAD51 protein.

a, b Huh7 and HepG2 cells were treated with 30 μM corylin for 48 h, and the expression of RAD51-AS1 and RAD51 was analyzed by quantitative real-time RT-PCR. GAPDH served as an internal control. ***p < 0.001. c Huh7 cells were transfected with siRNA against lncRNA RAD51-AS1 (siRAD51-AS1) or non-targeting siRNA (si-CTR) at 50 nM, and then co-treated with corylin (30 μM). After 48-h treatment, cells were harvested and lysates were subjected to western blotting to detect the level of RAD51. β-Actin served as an internal control (left panel). The quantitative results are shown in the right panel. ***p < 0.001. d Huh7 and HepG2 cells were transfected with 1 μg pcDNA-RAD51-AS1 expressing plasmid or empty vector for 48 h. The protein level of RAD51 was analyzed by western blotting (left panel). The quantitative results are shown in the right panel. ***p < 0.001. e, f Real-time PCR analysis shows the mRNA levels of RAD51-AS1 and RAD51 during the above-mentioned two treatments. GAPDH served as an internal control. All data were expressed as the mean ± S.D. of three independent experiments. **p < 0.01, ***p < 0.001
