Downregulation of PECAM1 and CXCR4 suppresses LPS-induced inflammation in HDPFs. (A,B) mRNA (A) and protein (B) expression of PECAM1 and CXCR4 in cells examined by RT-qPCR and western blot assays, respectively. (C–F) Levels of PGE2, TNF-α, IL-6, and IL-8 detected by ELISA kits. (G) Apoptosis of HDPFs determined by the TUNEL assay. Data were collected from three individual experiments and expressed as mean ± SD. Data were analyzed by one-way (C–G) or two-way ANOVA (A,B) followed by Tukey’s multiple comparison test. **p < 0.01 vs LPS + sh-NC; ##p < 0.01 vs. LPS + oe-NC.
