BBOX1 and cancer: As indicated in Table 1, high expression of BBOX1-AS1 was found to predict poor overall survival in four types of cancers: non-small cell lung cancer [39, 40], esophageal squamous cell carcinoma [41, 43, 44], hepatocellular carcinoma [46, 47], and cervical cancer [53], as well as inferior disease-free survival in hepatocellular carcinoma [47].
