Skeletal muscle lncRNAs upregulated by aging included HCCAT5, a hepatocellular carcinoma‐associated transcript (Liu et al., 2010, 2013), and MIR503HG, which has been implicated in endothelial‐to‐mesenchymal transition in vascular disease (Monteiro et al., 2021) (Figure 1b). The gene discussed is HCCAT5; the disease is hepatocellular carcinoma.
