On the contrary, upregulation of ALDH1B1 at the transcriptional level was significantly associated with higher overall survival in gastric cancer [211], while Yang et al. (2017) demonstrated that high expression levels of ALDH1B1 were correlated with a favorable prognosis in the case of hepatocellular carcinoma [210]. Here, ALDH1B1 is linked to hepatocellular carcinoma.
