miR-411 regulated ITCH expression and promoted cell proliferation in human hepatocellular carcinoma cells.

In this study, we report that miR-411 expression is markedly upregulated in HCC cells and HCC tissues compared with normal control tissues and cells. Previous studies have shown that miR-411 plays a crucial role in a variety of biological processes in various human cancer cells. However, the specific function of miR-411 in HCC remains unclear. Ectopic expression of miR-411 promoted the proliferation and anchorage-independent growth of HCC cells, whereas inhibition of miR-411 reduced this effect. Bioinformatics analysis further revealed ITCH, a putative tumor suppressor as a potential target of miR-411. Data from luciferase reporter assays showed that miR-411 directly binds to the 3'-untranslated region (3'-UTR) of ITCH mRNA and repressed expression at both transcriptional and translational levels. In functional assays, miR-411 promoted HCC cell proliferation, which could be suppressed by miR-411-in. Taken together, our data provide convincing evidence that miR-411 functions as an onco-miRNA, which was associated with cell proliferation of HCC, and its oncogenic effect is mediated chiefly through direct suppression of ITCH expression.

Authors: Zhou S, Wei J, Wang Y, Liu X Abstract Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated mortality worldwide. Despite clinical advances, the survival rate of patients with HCC remains low, as most patients are diagnosed with HCC when they are already at the advanced stage. Certain circular RNAs (circRNAs) are closely associated with the development of liver cancer. In the present study, a circRNA array was performed to screen differentially expressed circRNAs in HCC tissues. The further analysis focused on the newly identified circRNA_101237, the host gene of which, cyclin-dependent kin...

Authors: Li L, Zheng Y, Zheng Q, Jiang J Abstract The present study aimed to investigate the antiproliferative effect of embryonic stem cell-conditioned medium (ESC-CM) on the mouse liver cancer Hepa1-6 cells in vitro. Furthermore, in order to elucidate the underlying molecular mechanism, the microRNAs (miRNAs) in ESC-CM associated with the inhibition of Hepa1-6 proliferation were identified. Following the co-culture of ESC-CM and Hepa1-6 in Transwell chambers, the proliferation, cell cycle, apoptosis and associated protein expression were determined in Hepal-6 cells. Moreover, miRNA array analysis was employed to ...

Conclusion The elucidation of the function of circRNAs is an emerging field of science with a tremendous potential after previously being dismissed as RNA artifacts. They are ubiquitously expressed and thousands of members have already been identified. This fact only expands their potential to possibly enhance our knowledge to understand the difference between health and disease. Owing to their structure stability and their presence in exosomes circRNAs may also exert their function in an autocrine, paracrine and possible endocrine fashion. In addition, the fact that circRNAs are widely distributed in the cellular compart...

Recent studies identified that circ-ITCH Suppresses mutiple cancers proliferation via inhibiting the Wnt/beta-Catenin pathway. In current study, conducted a genetic association study together with epidemiological follow-up study to delineate the role of circ-ITCH in the development and progression of HCC. we found rs10485505 (adjusted OR =1.18; 95% CI=1.06-1.31; P value =3.1×10-3) ...

In this study, we showed that Dvl3 was significantly overexpressed in human hepatocellular carcinomas (HCCs) and promoted cancer stemness both in vitro and in vivo. We found that the non-phosphorylated (NP)-Dvl3 was more stable than the phosphorylated form, more active in activating β-catenin transcriptional activity, and more potent in enhancing self-renewal ability in HCC cells. Mechanistically, we confirmed that the homeodomain-interacting protein kinase-2 (HIPK2) and E3 ubiquitin ligase ITCH were able to physically bind to Dvl3 protein. Knockdown of HIPK2 and the protein phosphatase regulatory unit C-alpha (PP1C&a...

By Stacy SimonThe US Food and Drug Administration (FDA) has approved Keytruda (pembrolizumab) to treat people with head and neck squamous cell carcinoma that has spread or come back after previous chemotherapy treatment. It’s the first immunotherapy drug approved for head and neck cancer. Keytruda is already approved for melanoma and non-small cell lung cancer.The FDA based its approval on a clinical trial of 174 people with head and neck squamous cell carcinoma that had spread or come back after they were treated with platinum-based chemotherapy. Tumors shrank or disappeared in 16% of the participants who were given...

By Stacy SimonResults of a small clinical trial show that more than half the patients with Merkel cell carcinoma, a rare but aggressive type of skin cancer, improved when they took the immunotherapy drug Keytruda (pembrolizumab). And the improvement appears to be lasting longer than would be expected with standard treatment. This is a significant finding because there are currently no drugs that have been approved by the US Food and Drug Administration (FDA) to treat Merkel cell carcinoma. Researchers studying Keytruda and other drugs are trying to provide more treatment options for people with this type of skin cancer.Whi...
