The long noncoding RNA (lncRNA) LN-associated transcript 1 (ELNAT1) could induce Ubc9 overexpression, which would then mediate the SUMOylation of hnRNPA1 and promote packaging of ELNAT1 into the extracellular vesicles (EVs) secreted by bladder cancer cell. This evidence concerns the gene SNHG16 and urinary bladder cancer.
