CDK4 and cancer: ANGPTL4 was recently described in the SASP of hepatic stellate cells during replicative senescence (Odagiri et al. 2019), of prostate fibroblasts during DNA damage‐induced senescence (Zhang et al. 2018), of epithelial cells during centrosome amplification‐induced senescence (Wu et al. 2023), or of cancer cells during CDK4/6 inhibitor‐induced senescence (Gleason et al. 2023), confirming its induction in many cellular senescence models.
