A1BG and hepatocellular carcinoma: In this study, we found for the first time that A1BG-AS1 was low-expressed in PCa, and its overexpression inhibited cancer cell malignancy, which was similar to the results of Bai et al. [11] in hepatocellular carcinoma, suggesting that A1BG-AS1 is a class of antioncogene in PCa.
