Figure Lengend Snippet: p65 translocation is not inhibited by CERT knockdown. A: Mechanism of NF-κB pathway activation. B: HASTR/ci35 cells were transfected with control siRNA (siCTRL) or siRNA against CERT (siCERT) and incubated for 48 h. TNF receptor 1 protein expression levels were analyzed by western blotting (n = 3). C: The cells were further incubated with 3 ng/ml IL-1α and 50 ng/ml TNF-α for 15 min to 6 h. The protein levels of IκBα and phospho-IκBα (p-IκBα) were examined by western blotting (n = 3). D: The cells were further incubated with 3 ng/ml IL-1α and 50 ng/ml TNF-α for 15 min. The cells were fixed and immunostained for p65. Typical images were shown (n = 3). B, Student’s t test. C, Tukey’s test. All data are presented as mean ± SEM. ns, not significant.
