Progressive increase of GRP78 and GRP94 in EAM hearts. A. The sample blot was probed with antibodies specific to GRP94, GRP78, and GAPDH. B. The amount of GRP78 was normalized to the loading control, GAPDH. Significantly more GRP78 was present in EAM day 16 and EAM day 20 rats than in the controls. C. The amount of GRP94 was normalized with the loading control, GAPDH. A significantly increased amount of GRP94 was detected in EAM day 9 rats. * indicates p < 0.05., *** indicates p < 0.001.
