doi: 10.2147/JIR.S542033
Figure Lengend Snippet: IFIT3 knockdown relieved the intestinal inflammatory response and inhibited the activation of the STAT1/2 pathway in DSS-induced UC mice. ( A and B ) Comparison of colon transduction efficacy in mice between intraperitoneal injection of saline and AAV9 using paraffin sections ( A ) and the IVIS Lumina III imaging system ( B ). Scale bar = 100 µm. ( C ) Comparison of colon length between AAV9-shNC- and AAV9-shIFIT3-treated UC mice. ( D ) Weight changes in the two mouse groups. ( E ) Representative images and histological score of H&E staining in colon tissues from the two mouse groups. Scale bar = 100 µm (top) and 25 µm (bottom). ( F ) mRNA levels of IFIT3, TNF-α, IL-1β and IL-6 in colon tissues from the two mouse groups. ( G ) Protein expressions of STAT1, pSTAT1, STAT2, pSTAT2 and IFIT3 in colon tissues from the two mouse groups. Data was presented as mean ± SD (n = 5). * p < 0.05, ** p < 0.01, *** p < 0.001.
Article Snippet: The PVDF membranes were incubated with primary antibodies against IFIT3 (1:3000; #15201-1-AP, Proteintect), STAT1 (1:1000; # R25799 , Zenbio, Chengdu, China), pSTAT1 (1:1000; #bsm-52209R, Bioss, Beijing, China), STAT2 (1:1000; #R381419 Zenbio), pSTAT2 (1:1000; #bs-3428R, Bioss), and GAPDH (1:1000; #GB15002-100, Servicebio) overnight at 4 °C and then incubated with HRP-labeled secondary antibodies at room temperature for 1 hour.
