اعمال قاعدۀ خرق حجاب شخصیت حقوقی بر مدیران، به طلبکاران شرکت های تجاری اجازه می دهد بدون درخواست ورشکستگی یا انحلال شرکت، خسارت های مازاد بر سرمایۀ وارد بر خود را از مدیران مطالبه کنند. قاعدۀ خرق حجاب خود سبب دعوای مجزایی نیست و تنها دادگاه را مجاز می سازد در حالی که شخصیت حقوقی شرکت باقی است، مدیران را مسئول جبران خسارت های جبران نشده قرار دهد. بنابراین، مراجعه به مدیران سبب مستقلی نیاز دارد و...
It has been reported that miRNAs is deregulated in diverse human cancers, involving human cervical cancer. However, the clinical significances and potential mechanisms of miR-142 in the development and progression of cervical cancer were not elucidated completely till now. In this study, we found that the expression of miR- 142 was obviously down-regulated in human cervical cancer tissues and a...
Differential effects of natriuretic peptides and NO on LV function in heart failure and normal dogs.
beta-Adrenergic hyporesponsiveness in congestive heart failure (CHF) is mediated, in part, by nitric oxide (NO). NO and brain natriuretic peptide (BNP) share cGMP as a second messenger. Left ventricular (LV) function and inotropic response to intravenous dobutamine (Dob) were assessed during sequential intracoronary infusion of saline, HS-142-1 (a BNP receptor antagonist), and HS-142-1 + N(G)-m...
MicroRNAs are differentially expressed in cells and regulate multiple biological processes. We have been analyzing comprehensive expression patterns of microRNA in human and mouse embryonic stem and induced pluripotent stem cells. We determined microRNAs specifically expressed in these pluripotent stem cells, and miR-142-3p is one of such microRNAs. miR-142-3p is expressed at higher levels in i...
Canonical Wnt signaling is critical for the control of osteoblast differentiation in human mesenchymal stem cells. MicroRNAs (miRs) are essential regulators of cell differentiation by post‑transcriptional regulation of target gene expression. The aim of the present study was to investigate the molecular mechanism by which miR‑142‑3p promotes osteoblastic differentiation using the human fetal os...
Neutrophils play critical roles in vertebrate innate immune responses. As an emerging regulator in normal myelopoiesis, the precise roles of microRNA in the development of neutrophils have yet to be clarified. Using zinc-finger nucleases, we have successfully generated heritable mutations in miR-142a and miR-142b and showed that hematopoietic-specific miR-142-3p is completely deleted in miR-142...
An increase in cardiac workload, ultimately resulting in hypertrophy, generates oxidative stress and therefore requires the activation of both survival and growth signal pathways. Here, we wanted to characterize the regulators, targets and mechanistic roles of miR-142, a microRNA (miRNA) negatively regulated during hypertrophy. We show that both miRNA-142-3p and -5p are repressed by serum-deriv...
Aberrant expression of microRNAs (miRs) has been implicated in the pathogenesis of several neurodegenerative disorders. In HIV-associated neurocognitive disorders (HAND), miR-142 was found to be upregulated in neurons and myeloid cells in the brain. We investigated the downstream effects of chronic miR-142 upregulation in neuronal cells by comparing gene expression in stable clones of the human...
