To verify this possibility, we first collected HOTAIR-regulated genes annotated in different cancer types, including cervical cancer cells (Zheng et al, 2015), hepatocellular carcinoma (Wu et al, 2018), pancreatic cancer cells (Kim et al, 2012), gastrointestinal stromal tumors (Niinuma et al, 2012), and small-cell lung cancer (Ono et al, 2014). Here, HOTAIR is linked to gastrointestinal stromal tumor.
