CASC19 and cancer: While exploring the deregulated lncRNA profile in pancreatic cancer, we found a cardinal lncRNA, Cancer Susceptibility Candidate 19 (CASC19) which has been shown to be deregulated in several other cancer types such as gastric cancer, colorectal cancer, non-small cell lung carcinoma, cervical cancer and nasopharyngeal carcinoma (Liu et al. 2020, 2021; Qu et al. 2019; Wang et al. 2019a, b, 2020, 2023a, b, c; Zhao et al. 2019).
