For example, linc-UBC1 (LCAL6) was discovered in bladder cancer [32]; UCA1 (LCAL52) in bladder [33], ovarian [46] and breast cancer [47]; LINC00261 (LCAL62) in gastric cancer [31]; ESCCAL-1 (LCAL80) [30] and ENST00000547963 (LCAL84) [34] in esophageal squamous cell carcinoma; CCAT1 (LCAL85) in colon cancer [29]; and PART1 (LCAL92) in prostate cancer [35] and glioblastoma multiforme [48].
