In this study, global miRNA expression profiling was performed across a panel of nine human immune cell subsets (neutrophils, eosinophils, monocytes, B cells, NK cells, CD4 T cells, CD8 T cells, mDCs and pDCs) to identify cell-type specific miRNAs. mRNA expression profiling was performed on the same samples to determine if miRNAs specific to certain cell types (…) text/html http://www.ncbi.nlm.nih.gov NCBI PubMed 08.01.2012 | NCBI PubMed: Simple and rapid genetic testing for citrin deficiency by screening 11 prevalent mutations in SLC25A13. http://www.lsis.com/channels/?query=3 Citrin deficiency is an autosomal recessive disorder caused by mutations in the SLC25A13 gene and has two disease outcomes: adult-onset type II citrullinemia and neonatal intrahepatic cholestasis caused by citrin deficiency. The clinical appearance of these diseases is variable, ranging from almost no symptoms to coma, brain edema, and severe liver failure. Genetic testing for SLC25A13 mutations is essential for the diagnosis of citrin deficiency because chemical diagnoses are prohibitively (…) text/html http://www.ncbi.nlm.nih.gov NCBI PubMed 21.01.2012 | NCBI PubMed: A gene variation (rs12691) in the CCAT/enhancer binding protein ? modulates glucose metabolism in metabolic syndrome. http://www.lsis.com/channels/?query=3 BACKGROUND AND AIMS: CCAAT/enhancer-binding protein alpha (CEBPA) is a transcription factor involved in adipogenesis and energy homeostasis. Caloric restriction reduces CEBPA protein expression in patients with metabolic syndrome (MetS). A previous report linked rs12691 SNP in CEBPA to altered concentration of fasting triglycerides. Our objective was to assess the effects of rs12691 in glucose metabolism in Metabolic Syndrome (MetS) patients. METHODS AND RESULTS: Glucose metabolism was (…) text/html http://www.ncbi.nlm.nih.gov NCBI PubMed 19.01.2012 | NCBI PubMed: RAS mutations in cutaneous squamous-cell carcinomas in patients treated with BRAF inhibitors. http://www.lsis.com/channels/?query=3 Cutaneous squamous-cell carcinomas and keratoacanthomas are common findings in patients treated with BRAF inhibitors. |-| N Engl J Med. |-| Su F, Viros A, Milagre C, Trunzer K, Bollag G, Spleiss O, Reis-Filho JS, Kong X, Koya RC, Flaherty KT, Chapman PB, Kim MJ, Hayward R, Martin M, Yang H, Wang Q, Hilton H, Hang JS, Noe J, Lambros M, Geyer F, Dhomen N, Niculescu-Duvaz I, Zambon A, Niculescu-Duvaz D, Preece N, Robert L, Otte NJ, Mok S, Kee D, Ma Y, Zhang C, Habets G, Burton EA, Wong B, Nguyen (…) text/html http://www.ncbi.nlm.nih.gov NCBI PubMed 01.02.2012 | NCBI PubMed: Prognostic Factors in Central Neurocytomas: A Multicenter Study of 71 Cases. http://www.lsis.com/channels/?query=3 Central neurocytoma (CN) is a rare intraventricular tumor presenting a benign histologic appearance and favorable prognosis after surgery. In contrast, "atypical" CN is defined by a high MIB1 proliferation index and/or histologic features of malignancy, which are associated with a poorer outcome. This variant of CN remains somewhat controversial. To better characterize CN and its "atypical" variant, a retrospective multicenter study was conducted on 71 patients presenting with CN. A (…)
