Project description:The goal of this experiment was to identify possible genes affected directly or indirectly by anti-miR-191. Hepatocellular carcinoma (HCC) is a fatal disease with currently very limited beneficial therapies. MicroRNAs (miRs), which are considered to be master regulators of gene expression, have significant influence on cellular pathways and phenotype, and are de-regulated in HCC, and hence are thought to be of great therapeutic potential as novel targets. We identified hsa-miR-191 as a potential target for HCC therapy. Inhibition of this miR causes decreased cell proliferation and induction of apoptosis in vitro as well as a significant reduction of tumor mass in vivo in an orthotopic liver xenograft model. This miR was also found to be up-regulated by a dioxin, a known liver carcinogen, and was found to be a key regulator of cancer related pathways. HCC cell line treated with anti-miR-191, and treated with negative control anti-miR. Treatment was done twice (duplicates) but in independent studies.

Project description:Transcriptional profiling of Homo sapiens inflammatory skin diseases (whole skin biospies): Psoriasis (Pso), vs Atopic Dermatitis (AD) vs Lichen planus (Li), vs Contact Eczema (KE), vs Healthy control (KO) In recent years, different genes and proteins have been highlighted as potential biomarkers for psoriasis, one of the most common inflammatory skin diseases worldwide. However, most of these markers are not psoriasis-specific but also found in other inflammatory disorders. We performed an unsupervised cluster analysis of gene expression profiles in 150 psoriasis patients and other inflammatory skin diseases (atopic dermatitis, lichen planus, contact eczema, and healthy controls). We identified a cluster of IL-17/TNFα-associated genes specifically expressed in psoriasis, among which IL-36γ was the most outstanding marker. In subsequent immunohistological analyses IL-36γ was confirmed to be expressed in psoriasis lesions only. IL-36γ peripheral blood serum levels were found to be closely associated with disease activity, and they decreased after anti-TNFα-treatment. Furthermore, IL-36γ immunohistochemistry was found to be a helpful marker in the histological differential diagnosis between psoriasis and eczema in diagnostically challenging cases. These features highlight IL-36γ as a valuable biomarker in psoriasis patients, both for diagnostic purposes and measurement of disease activity during the clinical course. Furthermore, IL-36γ might also provide a future drug target, due to its potential amplifier role in TNFα- and IL-17 pathways in psoriatic skin inflammation.

Project description:Background: MicroRNAs(miRNAs) are a class of non-coding small RNAs, which play important roles in many physiological processes by regulating gene expression. Previously studies show that the expression level of total miRNAs increased during the progression of mouse embryonic development, and some miRNAs control the regulatory network in the development progression. Results: In this study,the results showed that the sperm samples with high expression of miR-191 had higher fertilization rate (FR), blastocyst rate (EER) and high-quality embryo rate (HQER). Conclusions: These findings suggest that higher miR-191-5p expression with better human early embryonic development, and indicate that the miR-191-5p could be a potential marker to access the quality of IVF.
