Figure 1. The expression of Sesns in atrium of patients and cells.
(A) The location of Sesns proteins expressed in atria detected by immunofluorescence. Sesns proteins stained with red fluorescence. Nuclei stained with blue fluorescence. Magnification: ×100. The location of Sesns proteins expressed in HL-1 cells and cardiac fibroblasts detected by immunofluorescence. Sesns proteins stained with green fluorescence. Nuclei stained with blue fluorescence. Magnification: ×400. (B) The expression of Sesns protein detected with western blot. Lane1: Molecular weight standards; Lane 2: Left atrium in SR group; Lane 3: Right atrium in SR group; Lane 4: Left atrium in PmAF group; Lane 5: Right atrium in PmAF group. Quantification of relative immunoreactivity for bands, SR group n = 23, PmAF group n = 19 *P < 0.05, **P < 0.01 compared with the SR group; #P < 0.05, ##P < 0.01 compared with the LA in the PmAF group. SR = Sinus rhythm; PmAF = Permanent AF; LA = left atrium, RA = right atrium.
