Figure 1. Inflammatory cytokines and p-Stat3 are elevated in muscles of patients with CKD.
A. Immunostaining of muscle sections for IL-6 and TNFα(brown color) from biopsies of age- and gender matched, healthy control subjects (left panel) and CKD patients (middle panel). Staining quantification is calculated as the percentage of muscle fibers that are immunostained (right panel; n=3 control subjects; n=4 CKD patients; ruler =50µm). B. Representative western blots for p-Stat3 in control subjects and CKD patients (upper panel) and the ratio of the intensity of p-Stat3 to total Stat3 (lower panel) (n=6 control subjects; n=6 CKD patients). C. Muscle sections from control subjects and CKD patients were immunostained for p-Stat3 (upper panel). Brown nuclei are p-Stat3 positive (arrows). Percentage of p-Stat3 positive nuclei in a total of 550 nuclei (lower panel; n=4 control subjects; n=6 CKD patients). Values are means±SEM. *p<0.05 vs. control subjects. (see also Figure S1, Table S1)
