Figure 4From: Low-Dose T3 Replacement Restores Depressed Cardiac T3 Levels, Preserves Coronary Microvasculature and Attenuates Cardiac Dysfunction in Experimental Diabetes MellitusDiabetes leads to reexpression of fetal genes in adult cardiac tissue. (A) MHC isoform mRNA distribution shown as % of total MHC mRNAs as measured by qPCR. (B) Protein expression of β-MHC isoform and total MHC detected by Western blot. Expression represented as ratio of β-MHC to total MHC expression. (C) Cardiac protein expression of sarcoplasmic reticulum proteins detected by Western blot. (D) Quantitative summary of normalized protein expression. MHC, myosin heavy chain; SERCA2a, sarcoplasmic/endoplasmic reticulum calcium ATPase 2; PLB, phospholamban; p-PLB, phosphorylated phospholamban (site of phosphorylation); n = 4–8/group. *p < 0.05 versus control; †p < 0.05 versus STZ/N.Back to article page
