For example, UCA1, LncRNA human ovarian cancer-specific transcript 2 (HOST2) and LncRNA nuclear enriched abundant transcript1 (NEAT1) are associated with lung cancer, ovarian cancer and prostate cancer, respectively (Chakravarty et al., 2014; Gao et al., 2015; Nie et al., 2016). Here, UCA1 is linked to ovarian cancer.
