For example, knocking down BZRAP1-AS1 in hepatocellular carcinoma (HCC) cells inhibits HUVEC proliferation, migration, and angiogenesis, the lncRNA tends to be an oncogene (Wang et al., 2019b); however, the conclusions are opposite in cervical cancer, prostate cancer, and lung adenocarcinoma (Tan, Jin & Wang, 2019; Zheng et al., 2020b; Tang et al., 2021). This evidence concerns the gene TSPOAP1 and hepatocellular carcinoma.
