Figure Lengend Snippet: DAPT-treatment of human lens B3 cells induces changes in endogenous JAG1 protein processing. (A) Endogenous JAG1, NOTCH2 and PSEN1 expression in B3 cell lysates. Each lane/strip blot contains 50 µg of B3 cell total protein that was separately probed with rabbit anti-Jag1, rabbit anti-Psen1 (N-terminus), or rat anti-Notch2 to reveal expression of FL-JAG1, PSEN1 and NOTCH2 proteins. The JAG1-CTF isoform was observable in longer exposures (not shown, see control lanes in Fig. 3 B,C). The NOTCH2 full length and N2-ICD isoforms were clearly detectable. (B–C) B3 cells treated with different concentrations of Epoxomicin versus DMSO (B), or 10 µM DAPT versus DMSO (C) for 24 h and cell lysates analyzed for JAG1 protein isoforms via western blot using rabbit anti-Jag1 antibody.
