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.
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.
In addition, lncRNA-UCA1 overexpression attenuated the inhibitory effects of miRNA-124 overexpression on cancer cell proliferation, migration and invasion.
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.
In the present review, we summarized current studies on UCA1 to explore its prognostic value and underlying regulation mechanisms in the development of multiple cancers in order to provide a glimmer of hope for the prevention and treatment of malignant tumors.
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.
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.
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).
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).
Urothelial carcinoma associated 1 (UCA1) functions as an oncogene, which promotes cancer cell proliferation, invasion, and metastasis, and is responsible for drug resistance.
Urothelial Cancer Associated 1 (UCA1), an lncRNA, is reportedly upregulated in human bladder carcinoma and promotes cancer cell proliferation, migration, invasion, and drug resistance.
