However, Peng et al. showed that CAMK2NA is a 1p36 tumor suppressor gene, and silencing and ectopic expression of CAMK2N1 enhanced and inhibited cell proliferation, colony formation, and xenograft tumor growth, respectively, in HCC nude mice (Peng et al., 2021). Here, CAMK2N1 is linked to hepatocellular carcinoma.
