Predicted targets of these miRNAs were involved in focal adhesion/integrin pathway and in actin cytoskeleton regulation. The identified miRNAs might contribute to molecular regulation of reverse remodeling and heart recovery mechanisms.”
“Background:

Long-acting reversible contraception (LARC) is underused in many countries in sub-Saharan Africa. Many previous attempts to increase uptake of this important class of contraception have not been successful.\n\nStudy Design: This program in Zambia employed 18 dedicated providers of LARC, placed them in high volume public sector facilities and collected routine, anonymous information over a 14-month period. We tallied uptake of LARC, analyzed user characteristics to see what populations were reached by the program and compared this to nationally representative data. We also estimated HIF activation costs per couple-year of protection of the program.\n\nResults: In a 14-month period, 33,609 clients chose MLN8237 either a subdermal implant (66%) or an intrauterine device (34%). The program reached a younger and lower parity population compared to nationally representative surveys of Zambian women using contraception. The estimated program costs, including the value of donated commodities, averaged $13.0 per couple-year of protection.\n\nConclusion: By having the necessary time, skills and materials – as well as a mandate

to both generate informed demand and provide quality services – dedicated providers of LARC can expand contraceptive choice. This new approach shows what can be achieved in a short period and in a region of the world where uptake of LARC is limited. (C) 2011 Elsevier Inc. All rights reserved.”
“Mouse models can provide useful information to understand molecular mechanisms of human tumorigenesis. In this study, the conditional thyroid mutagenesis of Pten and Ras genes in the mouse, which induces very aggressive follicular carcinomas (FTCs), has been used to identify genes differentially expressed among human normal thyroid tissue Epigenetics inhibitor (NT), follicular adenoma (FA), and FTC. Global gene expression of mouse FTC was compared

with that of mouse normal thyroids: 911 genes were found deregulated +/- 2-fold in FTC samples. Then the expression of 45 deregulated genes in mouse tumors was investigated by quantitative RT-PCR in a first cohort of human NT, FA, and FTC (discovery group). Five genes were found significantly down-regulated in FA and FTC compared with NT. However, 17 genes were found differentially expressed between FA and FTC: 5 and 12 genes were overexpressed and underexpressed in FTC vs FA, respectively. Finally, 7 gene products, selected from results obtained in the discovery group, were investigated in a second cohort of human tumors (validation group) by immunohistochemistry. Four proteins showed significant differences between FA and FTC (peroxisomal proliferator-activated receptor-gamma, serum deprivation response protein, osteoglycin, and dipeptidase 1).
