H19 and diabetes mellitus: Both lncRNA H19 and HDAC 4, 5 and 6 are crucial in skeletal muscle physiology (Zhang et al. 2020a; Ratti et al. 2015; Lu et al. 2000) and such inverse patterns of expression between the lncRNA, H19 and HDAC 4, 5 and 6 indicated towards a potential regulatory axis between them that might be correlated to aberrant skeletal muscle metabolism during diabetes.
