Long non-coding RNA UCA1 contributes to the progression of prostate cancer and regulates proliferation through KLF4-KRT6/13 signaling pathway.

Long non-coding RNAs (lncRNAs) UCA1 have been shown to paly an important regulatory roles in cancer biology, and UCA1 dysfunction is related to TNM stage, metastasis and postoperative survival in several cancers. However, the biological role and clinical significance of UCA1 in the carcinogenesis of prostate cancer (PC) remain largely unclear. Herein, we found that UCA1 was abnormally upregulated in tumor tissues from PC patients, and patients with high UCA1 levels had a significantly poorer prognosis.
