TNF and glomerulosclerosis: Podocyte injury or apoptosis has been suggested to initiate various glomerulosclerosis diseases.2, 15 lncRNAs, such as CCAT1, can participate in the regulation of cell proliferation, migration, and apoptosis by controlling the downstream pathways.13 Therefore, we studied the role of CCAT1 in podocyte injury induced by TNF‐α and investigate the underlying mechanism.
