A-B: Murine BSM strips devoid of urothelium and submucosa were
transduced with an adenovirus encoding GFP, desmin and vimentin for 48 h and the
total proteins from GFP, desmin and vimentin overexpressing murine BSM strips
were immunoprecipitated with JNK2 antibody. The resulting immunoprecipitate was
separated on a SDS-PAGE and subsequently probed with either anti-desmin and
anti-JNK2 antibodies (A) or anti-vimentin and anti JNK2 antibodies (B). The
input served as a loading control in both (A) and (B). C-F: Increased levels of
phospho JNK following desmin and vimentin overexpression. Total proteins
extracted from GFP, desmin and vimentin overexpressing murine BSM strips were
subjected to immunoblot analysis using phosphorylated JNK and total JNK2
antibodies. GAPDH was used as a loading control. D & F: Quantification of
immunoblots (C & E). Data are expressed as means ± SD, n = 5 mice in
each group. **, P < 0.01 versus GFP expressing murine BSM strips.
