Hide Abstract
MicroRNAs were reported to be involved in the modulation of tumor development. The aim of our study was to investigate the effect of miR-205 on proliferation and apoptosis of laryngeal squamous cell carcinoma (LSCC) and seek associations between miR-205 and Bcl-2 using in vitro and in vivo methods. Real-time qPCR was used to analyze the expression of miR-205 in LSCC samples and Hep-2 cell line. Apoptosis, cell cycle, and proliferation (MTT) assays were performed to test the apoptosis and proliferation of LSCC cells after miR-205 transfection. Bcl-2 expression in cells was assessed with Western blotting. The tumorigenicity of LSCC cells was evaluated in nude mice model. MiR-205 was significantly down-regulated in LSCC tissues compared to adjacent normal tissues. Lower expression of miR-205 was indicated to be statistically related with advanced clinical stage and T3-4 grades. We found that restoration of miR-205 down-regulated the proliferative markers of dihydrofolate reductase and proliferating cell nuclear antigen and apoptotic regulator of Bcl-2. The findings in vitro and in vivo showed miR-205 could suppress cell proliferation and induce cell apoptosis. In addition, Bcl-2 was identified as one of the direct targets of miR-205 in LSCC cells. These results suggest that miR-205 may play as a tumor suppressor in LSCC, probably by targeting Bcl-2 and serve as a potential target for therapeutic intervention.

Down-regulation of miR-129-5p inhibits growth and induces apoptosis in laryngeal squamous cell carcinoma by targeting APC.

Hide Abstract
miRNAs regulate gene expression and are key mediators of tumourigenesis. miR-129 has diverse effects in tumours, but its role in laryngeal squamous cell carcinoma (LSCC) remains unknown. This article focuses on the role of miR-129-5p in LSCC. We show miR-129-5p is upregulated in primary LSCC tumours and correlated with advanced disease. Down-regulating miR-129-5p suppressed cell proliferation and migration, and caused cell cycle arrest in Hep-2 cell lines. Downregulation of miR-129-5p alone is sufficient to induce apoptosis both in vivo and in vitro. Moreover, the growth of LSCC xenograft exposed to miR-129-5p antisense oligonucleotides (ASO) in BALB/c mice was markedly inhibited. In addition, we found that miR-129-5p targeted adenomatous polyposis coli (APC) to release inhibition of Wnt signalling causing cell growth and tumourigenesis. Our results suggest miR-129-5p functions as an oncogene in LSCC by repressing APC and is a potential therapeutic target for LSCC.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
