Our study was aimed at exploring the roles of lncRNA RP11-400K9.4 (RP11-400K9.4) on hypoxia/reoxygenation (H/R) -induced cardiomyocytes apoptosis. H/R model constructed in rat primary (PC) and H9c2 cells. In this study, results showed that significantly induced apoptosis PC The expression upregulated H/R-induced cells, but miR-423 downregulated. Silencing could attenuate We also found a potenti...
The decline of many amphibian species could be caused by their susceptibility to environmental pollutants that cause cellular stress and cell death. A variety of intracellular signal transduction pathways are activated by environmental stress factors, which result in cell death. Mitogen-activated protein kinases are intracellular signaling molecules that include the extracellular signal-regulat...
Extracellular signal-regulated kinase (ERK) 1/2, a well known regulator of gene expression, is likely to contribute to signaling events underlying enduring neural adaptations. Phosphorylated (phospho)-ERK was examined immunohistochemically after both single and repeated (i.e., sensitizing) doses of the partial D1-dopamine (DA) receptor agonist SKF-38393 (2,3,4,5-tetrahydro-7,8-dihydroxy-1-pheny...
MAPKs (mitogen-activated protein kinases) are key components in cell signalling pathways. Under optimal growth conditions, their activity is kept off, but in response to stimulation it is dramatically evoked. Because of the high degree of evolutionary conservation at the levels of sequence and mode of activation, MAPKs are believed to share similar regulatory mechanisms in all eukaryotes and to...
Mutations in RAS oncogenes are frequently observed in human cancers, and the mutations result in activation of the RAS-RAF-MEK-ERK pathway, leading to cell proliferation and survival. The pathway is, therefore, a potent therapeutic target in the RAS-mutant cancers. MEK inhibitors can specifically block the pathway and are one of the key types of drugs for the treatment of the RAS-mutant cancers...
Drugs that inhibit the MAPK pathway have therapeutic benefit in melanoma, but responses vary between patients, for reasons that are still largely unknown. Here we aim at explaining this variability using pre- and post-MEK inhibition transcriptional profiles in a panel of melanoma cell lines. We found that most targets are context specific, under the influence of the pathway in only a subset of ...
Introduction: Human exfoliated deciduous teeth–derived stem cells (SHEDs) have been shown as an excellent source of bone regeneration. Interleukin-17A (IL-17A) facilitates differentiation in various cell types, including SHEDs. In this study, we demonstrated IL-17A’s stimulating effect on SHEDs osteogenic and further evaluated the role ERK/MAPK signaling pathway process. Methods: The function I...
We devise hybrid high-order (HHO) methods for the acoustic wave equation in time domain. first consider second-order formulation time. Using Newmark scheme temporal discretization, we show that resulting HHO-Newmark is energy-conservative, and this also amenable to static condensation at each step. then of as a first-order system together with singly-diagonally implicit explicit Runge-Kutta (SD...
Glutamine (GLN) has many types of biological activity in rats, including anti-inflammatory, antioxidative stress, and anti-apoptosis effects. However, little is known about the effects GLN on bovine mammary epithelial cells (BMEC). γ-d-Glutamyl-meso-diaminopimelic acid (iE-DAP) a cell wall peptidoglycan component gram-negative bacteria that can be recognized by intracellular receptor nucleotide...
We have shown previously in the developing cerebral cortex that estrogen elicits the rapid and sustained activation of multiple signaling proteins within the mitogen-activated protein (MAP) kinase cascade, including B-Raf and extracellular signal-regulated kinase (ERK). Using estrogen receptor (ER)-alpha gene-disrupted (ERKO) mice, we addressed the role of ER-alpha in mediating this action of e...
