Urothelial carcinoma associated 1 (UCA1) functions as an oncogene, which promotes cancer cell proliferation, invasion, and metastasis, and is responsible for drug resistance.
Upregulated lncRNA-UCA1 contributes to metastasis of bile duct carcinoma through regulation of miR-122/<i>CLIC1</i> and activation of the ERK/MAPK signaling pathway.
This study thus reveals a new mechanism by which a hypoxic microenvironment promotes tumor metastasis, and highlights UCA1 as a potential biomarker for predicting the metastasis of gastric cancer to guide clinical treatment.
The UCA1-miR-204-CXCR4 regulatory network regulated the growth and metastasis of PCa, providing new insight in the management of patients with such malignancy.
Taken together, UCA1 might promote proliferation and migration of glioma, to regulate the tumor growth and metastasis via miR-182 dependent iASPP regulation.
Our findings provide the convincing evidence that the UCA1 plays an important role in the metastasis of EC and may serve as a novel molecular marker to predict the aggressive tumor progression and unfavorable prognosis of EC patients.
Long noncoding RNA urothelial carcinoma associated 1 (UCA1) has been implicated in the growth and metastasis of colorectal cancer (CRC), and autophagy contributes to tumorigenesis and cancer cell survival.
Long noncoding RNA UCA1 promotes osteosarcoma metastasis through CREB1-mediated epithelial-mesenchymal transition and activating PI3K/AKT/mTOR pathway.
In this review, I plan to place a special emphasis on HA/CD44-induced signaling pathways and the presence of several novel miRNAs (e.g., miR-10b/miR-302/miR-21) and lncRNAs (e.g., UCA1) together with their target functions (e.g., tumor cell migration, invasion, and chemoresistance) during cancer development and progression.
In the present work, we revealed that UCA1 silencing suppressed proliferation and metastasis and induced apoptosis of OSCC cell lines in vitro and in vivo, which might be related to the activation level of the WNT/β-catenin signaling pathway.
In the present study, we identified differential expression of UCA1 in colorectal cancer (CRC) and paired peritumoral tissues using gene expression microarray analyses. qPCR analysis confirmed that UCA1 was upregulated in CRC (p<0.001) and the expression of UCA1 was statistically correlated with lymph node metastasis (P=0.040), distant metastasis (P=0.043) and tumor stage (P=0.010).
In the present study, we found that UCA1 was aberrantly upregulated in gastric cancer tissues and gastric cancer cell lines, and was associated with TNM stage and metastasis.
In addition, UCA1 could reverse the inhibitory effect of miR-216b on the growth and metastasis of HCC cells, which might be involved in the derepression of fibroblast growth factor receptor 1 (FGFR1) expression, a target gene of miR-216b, and the activation of ERK signaling pathway.
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.
