Collagen dynamics were not involved in Golgi stress signaling.

<p>(A) NIH3T3 cells treated with GalNAc-bn for the indicated periods were examined by western blot analysis using antibodies against type I collagen. (B) NIH3T3 cells were stained with anti-type I collagen antibodies and anti-type IV collagen antibodies at 24 h after GalNAc-bn stimulation. Cont, untransfected cells; Scr, scrambled siRNA-transfected cells; siRNA, HSP47 siRNA-transfected cells. Scale bar: 50 µm.
