چکیده
Downlo atocellular carcinoma (HCC) is generally a fatal disease due to a paucity of effective treatment options. entification of oncogenic microRNAs that exert pleiotropic effects in HCC cells may offer new theratargets. In this study, we have identified the human microRNA miR-191 as a potential target for HCC y. Inhibition of miR-191 decreased cell proliferation and induced apoptosis in vitro and significantly d tumor masses in vivo in an orthotopic xenograft mouse model of HCC. Additionally, miR-191 was to be upregulated by a dioxin, a known liver carcinogen, and was found to be a regulator of a variety found of cancer-related pathways. Our findings offer a preclinical proof of concept for miR-191 targeting as a rational strategy to pursue for improving HCC treatment. Cancer Res; 70(20); 8077–87. ©2010 AACR.

Downlo roRNAs (miRNA), a class of natural RNA-interfering agents, have recently been identified as attractive s for therapeutic intervention. The rationale for developing miRNA therapeutics is based on the premise berrantly expressed miRNAs play key roles in the development of human disease, and that correcting miRNA deficiencies by either antagonizing or restoring miRNA function may provide a ...

Downlo DNA damage response (DDR) activates downstream pathways including cell cycle checkpoints. The D1 gene is overexpressed or amplified in many human cancers and is required for gastrointestinal, , and skin tumors in murine models. A common polymorphism in the human cyclin D1 gene is atively spliced, resulting in cyclin D1a and D1b proteins that differ in their carboxyl terminus. Cyclin erex...

Downlo cer vaccine feasibility would benefit from reducing the number and duration of vaccinations without ishing efficacy. However, the duration of in vivo studies and the huge number of possible variations cination protocols have discouraged their optimization. In this study, we employed an established model of preventive vaccination using HER-2/neu transgenic mice (BALB-neuT) to validate o–d...
