Human embryonic stem (hES) cells with the capacity of self-renewal and multilineage differentiation are promising sources for generation of pancreatic islet cells for cell replacement therapy in diabetes. Here we induced hES cells into insulin-producing cells (IPCs) in a stepwise process which recapitulated islet organogenesis by directing cells through the stages resembling definitive endoderm...
مقدمه: سرطان معده، از متداول ترین سرطان ها در جهان و دومین عامل مرگ انسان در اثر سرطان است. micrornas گروهی از rnaهای درون زاد کوچک غیر کد کننده با طول 23-21 نوکلئوتید هستند. افزایش بیان 372-mir در برخی سرطان ها، با کاهش بیان هدف آن (2lats) نقش انکومیری دارد. کاهش بیان 2lats منجر به عدم تنظیم چرخه ی سلولی، آپوپتوز و تکثیر سلولی می گردد. روش ها: در این مطالعه، با استفاده از ترانسداکشن لنتی ویروس...
MicroRNAs (miRNAs) are small non-coding RNAs that regulate translation of mRNA into protein and play a crucial role for almost all biological activities. However, the identification of miRNAs from mesenchymal stem cells (MSCs), especially from dental pulp, is poorly understood. In this study, dental pulp stem cells (DPSCs) were characterized in terms of their proliferation and differentiation c...
The tonalness spectrum shows the likelihood of a spectral bin being part of a tonal or non-tonal component. It is a non-binary measure based on a set of established spectral features. An easily extensible framework for the computation, selection, and combination of features is introduced. The results are evaluated and compared in two ways. First with a data set of synthetically generated signal...
Response 4: The introduction will be changed to contain: Sussmann et al. 2013 did a similar study on the inter-comparison of methane from MIR and NIR retrievals. They used a Tikhonov-L1 regularized profile retrieval scheme with the standard NDACC retrieval package SFIT2 for the MIR and the standard TCCON retrieval (GFIT) for the NIR spectra. They conclude that the obtainable information from th...
AIMS Endothelial cell injury induced by inflammatory factors plays a critical role in the pathogenesis of numerous vascular diseases. MicroRNAs are well known to be implicated in cell proliferation and apoptosis in inflammatory responses; however, it remains to be determined whether microRNAs are associated with tumour necrosis factor (TNF)-α-mediated endothelial cell injury. The aim of the pre...
TO THE EDITOR: Several recent studies investigated the role of microRNAs (miRNAs) in liver regeneration. These studies are typically based on microarray analyses of whole liver tissue, followed by quantitative real-time PCR or Northern blot confirmation. So far, nine studies have been published in this field (1– 4, 6, 7, 9 –11), of which five studies (1, 2, 7, 9, 11) show a similar design in re...
Breast cancer is the second leading cause of cancer mortality in women worldwide. Molecular therapy is needed to improve the outcome in patients with breast cancer. miR-203 participates in cancer cell proliferation, transformation, and apoptosis. This study showed that miR-203 was upregulated in breast cancer tissues and the MCF-7 cell line. miR-203 knockdown suppressed colony formation and tra...
Hundreds of circular RNAs (circRNAs) are highly abundant in the mammalian brain, often with conserved expression. Here we show that the circRNA Cdr1as is massively bound by the microRNAs (miRNAs) miR-7 and miR-671 in human and mouse brains. When the Cdr1as locus was removed from the mouse genome, knockout animals displayed impaired sensorimotor gating-a deficit in the ability to filter out unne...
