Article Title: Dextran sulfate sodium-induced chronic colitis attenuates Ca 2+ -activated Cl − secretion in murine colon by downregulating TMEM16A
doi: 10.1152/ajpcell.00328.2017
Figure Lengend Snippet: Effect of dextran sulfate sodium (DSS)-colitis on Cl− channel protein expression in murine colon. A: representative images of protein expression of the different characterized Cl− channels from epithelial lysates. BEST2, bestrophin-2. B: transmembrane protein 16A (TMEM16A) protein expression normalized to β-actin for quantification of control and DSS-colitis groups. TMEM16A expression (closed bar) is significantly decreased in DSS-colitis mice as compared with control. C and D: summarized data of Western blot quantification of BEST2 and CFTR normalized to β-actin in control and DSS-colitis mice. Neither protein was significantly altered from the control cohort. Bar graphs of summarized data represent means ± SE of 5 different animals from each respective group. *P < 0.05, compared with their respective control.
Article Snippet: PVDF membranes were then incubated in primary antibody: TMEM16A 1:500, CFTR 1:200, bestrophin-2 (BEST2) 1:500, muscarinic 3 (M 3 ) receptor 1:200 (Alomone Laboratories), inositol (1,4,5)-trisphosphate (IP 3 ) receptor 1:500, β-actin 1:1,000 (Cell Signaling, Danvers, MA) overnight at 4°C.
