For example, we found human lincRNAs NAG7, MEG3, PCAT1, CASC2 and LINC00032, which were involved in nasopharyngeal carcinoma [33], glioma and bladder cancer [34], [35], prostate cancer [36], endometrial cancer [37] and melanoma [38]. The gene discussed is PCAT1; the disease is central nervous system cancer.
