Role of long non-coding RNA urothelial carcinoma associated antigen 1 as a competing endogenous RNA in the regulation of the initiation and progression of tumor / 国际肿瘤学杂志

Long non-coding RNA urothelial carcinoma associated antigen 1 (UCA1) is highly expressed in multiple types of tumors,such as bladder cancer,breast cancer,colorectal cancer and so on.Recent studies show that UCA1 can interact with the microRNAs as a competing endogenous RNA (ceRNA),to indirectly regulate the expression of target genes,and then participates in the regulation of the initiation and progression of tumor.Therefore,using the mechanism of ceRNA to intervene the expression of UCA1 will provide new ideas for tumor treatment.

Expressions and roles of long non-coding RNA UCA1 in tumors / 国际肿瘤学杂志

Urothelial carcinoma associated antigen 1(UCA1)is a highly bladder cancer-specific long non-coding RNA(lncRNA),and it does not have the function of encoding protein. UCA1 differentially expre-sses in various fetal tissues,but its expression is turned off in most adult tissues. It reactivates during tumori-genesis. Researches indicate that UCA1 may regulate cell proliferation,apoptosis,metastasis and chemoresis-tance of tumors,such as bladder cancer,breast cancer and hepatocellular cancer.
