Mathematical modeling of kinetic processes with different time scales allows a reduction of the governing equations using quasi-steady-state approximations (QSSA). A QSSA theorem is applied to a modified mathematical model of the microRNA-mediated protein translation process. By an appropriate normalized procedure the system of seven nonlinear ordinary differential equations is rewritten in a f...

MicroRNAs are an important class of gene expression regulators that are involved in many biological processes including embryogenesis. miR-125b is a conserved microRNA that is enriched in the nervous system. We have previously reported the function of miR-125b in neuronal differentiation of human cell lines. We also discovered the function of miR-125b in regulating p53 in human and zebrafish. H...

Objective(s): The aim of the present study was to investigate the effects of genistein and exercise on the spatial memory and expression of microRNA-132, BDNF, and IGF-1 in the hippocampus of ovariectomized rats. Materials and Methods: Sixty animals were divided into six groups of control, sham, ovariectomy (OVX), ovariectomized with 8 weeks of genistein administration (OVX.G), with 8 weeks of ...

We designed a new SVM for microRNA identification, whose novelty is two-folded: firstly many of its features incorporate the base-pairing probabilities provided by McCaskill’s algorithm, and secondly the classification performance is improved by using a certain similarity (“profile”based) measure between the training and test microRNAs and a set of carefully chosen (“pivot”) RNA sequences. Comp...

Colon cancer constitutes a major challenge all over the world, which has fourth highest incidence and third mortality rate of cancers. Although therapeutic modalities have been improved in recent years, 5 y survival remains low. Oxymatrine is one main active compounds extracted from roots Sophora flavescens was found with effect for colon Recently, microRNAs recognized as type diagnostic progno...
