Fig. 5From: Transcriptional activation of USP16 gene expression by NFκB signalingEnhancement of USP16 transcription in response to p65, LPS and TNFα. (a) HEK293 Cells were transfected with either empty vector (pMTF) or the p65 expression plasmids (pMTF-p65) for 24 h, and USP16 mRNA levels were determined by qRT-PCR. (b) SH-SY5Y cells were exposed to LPS at 50 ng/ml for 24 h. Total RNA was extracted. The mRNA levels of USP16 were determined by qRT-PCR and normalized against the levels of GAPDH. HEK293 cells (c) and SH-SY5Y cells (d) were exposed to TNFα at 10 ng/ml for 24 h. The mRNA levels of endogenous USP16 gene were determined by qRT-PCR and normalized against the levels of GAPDH. All data are presented as mean ± SEM. n = 3, *p < 0.01, by analysis of variance with Student’s t-test. MEF WT and p65 KO cells (e) were exposed to TNFα at 5 ng/ml for 24 h, and mRNA levels of USP16 and GAPDH were examined by RT-PCR. (f) The endogenous mRNA levels of USP16 were normalized against the levels of GAPDH and analyzed by two-way ANOVA test followed by post-hoc Turkey’s test. The values represent means ± SEM. n = 3, ***p < 0.001Back to article page
