SSTR5 and urinary bladder carcinoma: We identified 8 lncRNAs of high level (LINC00221, UCA1, ZFHX4-AS1, LINC00284, LOC283731, LINC00698, CNTFR-AS1, and LOC284379) and 4 lncRNAs of low level (LINC00390, SSTR5-AS1, HECTD2-AS1, and LOC400696) were significantly related to the progression of muscle-invasive bladder cancer (Figure 2B).
