STX12 and urinary bladder cancer: To further evaluate how LINC00857 contributes to platinum‐based chemotherapy response in bladder cancer, we evaluated the expression levels of LINC00857 target genes that were identified in lung cancer.20 In MIBC, the expression of DIAPH3, EMR2, MMP1, STX12, and UHMK1 was found to be significantly associated with response to Gem/Cis (Figure 4A) and other platinum‐based chemotherapy (Figure 4B).
