Egr-1 protein is markedly induced in skeletal muscle of wasted pancreatic cancer patients. Protein levels of skeletal muscle EGR-1 and β-tubulin (loading control) were determined by Western immunoblotting showing aberrant upregulation of Egr-1 in skeletal muscle of patients with cancer cachexia. Western immunoblotting of Egr-1 (green band, 82 kDa) and β-tubulin (red band, 55 kDa) compares (A) two non-cachectic with two cachexia-associated biopsy protein extracts and (B) one non-cachectic probe with three cachexia-associated skeletal muscle biopsy samples. Similar results were obtained in three independent experiments. M – coomassie-blue prestained protein marker. Full-length blots/gels are presented in Additional file 3: Figure S2. (C) Densitometric analysis of Egr-1 protein expression. Median rate = 10.23, P-value ≤ 0.005 according to Student’s t-test.
