Oncogenic functions of lncRNA-UCA1 have been reported in several cancer types, including colon cancer, breast cancer, and melanoma moreover, it is interesting to note that, as well demonstrated by Xue et al., this lnc can be transported by exosomes released by hypoxic bladder cancer, prompting tumour growth once internalized by normoxic cells [119]. This evidence concerns the gene UCA1 and urinary bladder cancer.
