From: DAD3 targets ACE2 to inhibit the MAPK and NF-κB signalling pathways and protect against LPS-induced inflammation in bovine mammary epithelial cells

Figure 4

Effects of ACE2 silencing and DAD3 treatments on the transcriptional or expression levels of RAS members. A-E BMEC were treated with either control siRNA (scrambled) or ACE2-siRNA for 24 h, followed by treatment with 0.5 μg/mL LPS for 24 h. After washing with PBS, cells were treated with 20 μg/mL DA or 20 μg/mL DAD3 for 24 h. The ACE2, AT1R and AT2R relative mRNA levels (transcriptional levels) of RAS members were determined by RT-qPCR. The Ang II and Ang-(1–7) protein expression levels of RAS members were determined by ELISA. A Relative ACE2 mRNA levels. B Expression levels of Ang II. C Expression levels of Ang-(1–7). D Relative AT1R mRNA levels. E Relative AT2R mRNA levels. All data were represented as the mean ± SEM (n = 3). ns, represents no significant difference (p > 0.05); * represents p < 0.05; ** represents p < 0.01; and *** represents p < 0.001.
