(A) Total Cx43 levels under basal (−) and decidual hormone (E/P/c)-treated (+) conditions in ESC derived from subjects with endometriosis (E) and controls (C) (top panel). Two isoforms (arrows) correspond to putative phosphorylated (upper) and unphosphorylated (lower) species. Antisera selective for phospho-Ser 368 Cx43 (second panel), non-phospho-Ser 368 Cx43 (third panel), Cx26 (fourth panel), Cx32 (fifth panel) and β-actin (sixth panel). (B) Digitized western blots analyzed as integrated Cx43/β-actin density ratios without versus with 7 days of decidualizing hormones in control versus endometriosis ESC.
