Background: The effects of electromagnetic field (EMF) on reproductive system have been of critical concern for a long time. It has been shown that the EMF can adversely affect testicular cells and tissue and decrease male fertility. The most important determinants of male fertility are sperm development and motility, which are affected by changes in several factors including lipocalin 2 protei...

objective: micro-rnas (mirnas) are a class of posttranscriptional regulators that play crucial roles in various biological processes. emerging evidence suggests a direct link between mirnas and development of several diseases including type 2 diabetes (t2d). in this study, we aimed to investigate the effect of predicted mirna and target genes on insulin resistance. materials and methods: this e...

drought and salinity stress are adverse environmental factors that affect crop growth and yield. abiotic stress cause some reaction in plants such as change in gene expression, cell metabolism, growth and yield. moreover, stress condition resulted in increase of reactive oxygen species and disturbe macromolecules such as proteins, fatty acids, nucleic acid and pigments. in order to evaluate sal...

We have previously reported that NS-398, a cyclooxygenase-2 (COX-2)-selective inhibitor, inhibited replicative cellular senescence in human dermal fibroblasts and skin aging in hairless mice. In contrast, celecoxib, another COX-2-selective inhibitor, and aspirin, a non-selective COX inhibitor, accelerated the senescence and aging. To figure out causal factors for the senescence-modulating effec...

Aims: Our previous study demonstrated favorable changes in plasma protein levels such as adiponectin by fomentation healthy people. We also reported that the thermal stimulation caused of mRNA to prevent atherosclerosis human skeletal muscle-derived cell (SMDC). However, number decreased 74.6% heat stimulation. In order clarify this mechanism, we investigated whether affects related density or ...

Identification of all genes involved in the phytochrome (phy)-mediated responses of plants to their light environment is an important goal in providing an overall understanding of light-regulated growth and development. This article highlights and integrates the central findings of two recent comprehensive studies in Arabidopsis that have identified the genome-wide set of phy-regulated genes th...

Insulin regulates the expression of more than 150 genes, indicating that this is a major action of this hormone. At least eight distinct consensus insulin response sequence (IRSs) have been defined through which insulin can regulate gene transcription. These include the serum response element, the activator protein 1 ('AP-1') motif, the Ets motif, the E-box motif and the thyroid transcription f...

Major brassinosteroid (BR) effects such as BR-induced growth are mediated through genomic pathways because RNA synthesis inhibitors and protein synthesis inhibitors interfere with these processes. A limited number of BR-regulated genes have been identified hitherto. The majority of genes (such as BRU1, CycD3, Lin6, OPR3, and TRIP-1) were identified by comparisons of BR-treated versus control-tr...

ARPP-16, ARPP-19, and ENSA are inhibitors of protein phosphatase PP2A. ARPP-19 and ENSA phosphorylated by Greatwall kinase inhibit PP2A during mitosis. ARPP-16 is expressed in striatal neurons where basal phosphorylation by MAST3 kinase inhibits PP2A and regulates key components of striatal signaling. The ARPP-16/19 proteins were discovered as substrates for PKA, but the function of PKA phospho...

micrornas (mirnas) are short rna molecules which bind to target mrnas, resulting in translational repression and gene silencing and are found in all eukaryotic cells. approximately 2200 mirna genes have been reported to exist in the mammalian genome, from which over 1000 belong to the human genome. many major cellular functions such as development, differentiation, growth, and metabolism are kn...
