Xian et al. have found that lncRNA HULC (hepatocellular carcinoma upregulated long noncoding RNA) and ZNFX1-AS1 (ZNFX1 antisense RNA 1) can distinguish gastric cancer patients from healthy controls and have proposed them as biomarkers for diagnosing gastric cancer [77]. Here, ZNFX1 is linked to hepatocellular carcinoma.
