No isoform shift (dominance of the /1 myosin heavy chain) in ventricular myocardium.24 In contrast, isoform shift from a myosin heavy chain to ,B myosin heavy chain in atrial tissue.2' Altered Increased ventricular expression of atrial light chain 1 in DCM26; decreased light chain 2 in DCM.27 Unaltered No change in a skeletal to a cardiac ratio mRNA in DCM and 1CM.2' Altered Increased expression of isoform TnT2.20
