Cancer&Entry Information

Cancer Name	bladder cancer
ICD-0-3	C67
Methods	qPCR, Western blot, RIP
Sample	healthy bladder immortalized cell line (SV-HUC-1) and cancerous cell lines (J82, T24, SW780, TCC, EJ), BCa tissues and matched adjacent healthy ones
Expression Pattern	down-regulated
Function Description	lncRNA HLA complex group 22 (HCG22) was weakly expressed in BCa samples and lowly expressed HCG22 was closely correlated with low overall survival of the BCa patient. To verify the role of HCG22 in BCa progression, functional experiments were carried out in two representative BCa cells (J82 and T24) and the negative effects of HCG22 expression on the cell proliferation, migration, and epithelial-mesenchymal transition were identified. Mechanistically, polypyrimidine tract-binding protein 1 (PTBP1), which was highly expressed in BCa tissues and cell lines, was negatively regulated by HCG22 and the PTBP1-mediated Warburg effect was also obstructed by HCG22. Furthermore, HCG22 modulated the expression of PTBP1 through destabilizing human antigen R (HuR). And functional rescue assays confirmed that HCG22 functioned in bladder cancer through downregulating PTBP1.
