Fig. 4From: Role of ghrelin in the pancreatic exocrine secretion via mitogen-activated protein kinase signaling in ratsLevel of pancreatic extracellular-signal-regulated kinases (ERK), phosphorylated extracellular-signal-regulated kinases (pERK) and c-Jun N-terminal kinase (JNK) expression by using western blotting. Protein sample from pancreatic tissue of rats treated with ghrelin (10.0 μg/kg BW) was analyzed by western blot (a) and their bands were determined by pixel intensity analysis using NIH Image J (b). The values are expressed as the average with SEM (n = 4). Asterisk shows significant difference with the ghrelin-untreated group (*p < 0.05, **p < 0.01)Back to article page
