Long non-coding RNAs (lncRNAs) have been shown to have important regulatory roles in cancer biology, and the lncRNA UCA1 is upregulated in several cancers such as bladder cancer, breast cancer and colorectal cancer, however, the contributions of UCA1 to esophageal cancer remain largely unknown.
However, whether the aberrant expression of UCA1 in non-small cell lung cancer (NSCLC) is associated with malignancy, metastasis or prognosis has not been characterized.
Urothelial carcinoma associated 1 (UCA1) functions as an oncogene, which promotes cancer cell proliferation, invasion, and metastasis, and is responsible for drug resistance.
The lncRNA urothelial carcinoma associated 1 (UCA1) has been observed to be upregulated and to function as an oncogene in certain types of cancer; however, the role of UCA1 in RCC remains to be elucidated.
The strength of association between UCA1 and cancer prognosis was assessed by computing the hazard ratio (HR) with its corresponding 95% confidence interval (CI).
Urothelial Cancer Associated 1 (UCA1), an lncRNA, is reportedly upregulated in human bladder carcinoma and promotes cancer cell proliferation, migration, invasion, and drug resistance.
The result showed that high UCA1 expression was correlated with more LNM (OR=2.50, 95 %CI: 1.58-3.96, p<0.0001) in a random-effects model (I2=45 %, p=0.08) and could predict poor OS in cancer patients, with pooled hazard ratio (HR) of 1.65 [95% confidence interval (CI) 1.44-1.88, p<0.00001] indicated by a fixed-effects model (I2=35%, p=0.11).
According to recent studies, long noncoding RNA urothelial carcinoma associated 1 (UCA1) is involved in the development and progression of many malignant tumors, including gastric cancer (GC).
Mechanistically, we found that UCA1, one of the most important lncRNAs in malignancies of the urinary system, may be a potential mediator contributing to the tumor suppressor function of ART.
There was also a significantly negative association between high level of UCA1 and poor grade cancer (pooled OR = 2.74, 95% CI 2.04-3.70, p < 0.001) and positive lymphatic metastasis (pooled OR = 2.43, 95% CI 1.72-3.41, p < 0.001).
In the second part of this review, we focus on the role of lncRNA Urothelial Cancer Associated 1 (UCA1) to integrate research in different types of cancer in order to decipher its putative function and mechanism of regulation in colorectal cancer cells.
This study demonstrated that the NR2C2-uORF impaired the pivotal roles that UCA1-miR-627-5p-NR2C2 feedback loop had in regulating the malignancies of glioma cells by targeting NR2C2 directly.
In view of the poor prognosis of laryngeal squamous cell carcinoma (LSCC) and the functionality of long non-coding (lnc)RNA UCA1 in different types of cancer, the present study aimed to investigate the role of UCA1 in the development and progression of LSCC.
Here, we review the crosstalk between UCA1 and miRNAs during the pathogenesis of cancer, with a focus on cancer-cell proliferation, invasion, drug resistance, and metabolism.
Long non-coding RNA urothelial carcinoma-associated 1 (UCA1) has a role in various common types of human malignancy, including cholangiocarcinoma; however, the expression and function of UCA1 in intrahepatic cholangiocarcinoma (ICC) has remained elusive.
