Evidence suggests that the overexpression of CASC19 in Clear Cell Renal Cell Carcinoma (ccRCC) might play an oncogenic role in cancer progression [19], and knockdown of CASC19 suppressed cell proliferation, migration, and invasion in nonsmall cell lung carcinoma (NSCLC) [20,21]. Here, CASC19 is linked to non-small cell lung carcinoma.
