Purpose: To investigate the protective effect of aspirin against preeclampsia and involvement p38MAPK signaling pathway in process.Methods: Sixty pregnant women who underwent antenatal care delivery at Chancheng Central Hospital from September 2020 to 2022 were selected equally assigned control group (CG) experimental (EG). From 12th week gestation, EG was administered 100 mg 1000 calcium carbo...

The present study investigated whether there is an interaction between reactive oxygen species (ROS) and p38 mitogen-activated protein kinase (MAPK) during chemical hypoxia-induced injury in PC12 cells. The results of the present study showed that cobalt chloride (CoCl₂), a chemical hypoxia agent, markedly induced ROS generation and phosphorylation of p38MAPK, as well as neuronal injuries. N-ac...

BACKGROUND AND OBJECTIVES Endothelial cell migration is essential for tumor angiogenesis, and interleukin-8 (IL-8) has been shown to play an important role in tumor growth, angiogenesis, and metastasis. The objective of this study was to investigate the molecular mechanism of IL-8 induced endothelial cell migration in vitro. MATERIAL AND METHODS Fluorescence microscope was used to study the d...

Cellular senescence suppresses cancer by forcing potentially oncogenic cells into a permanent cell cycle arrest. Senescent cells also secrete growth factors, proteases, and inflammatory cytokines, termed the senescence-associated secretory phenotype (SASP). Much is known about pathways that regulate the senescence growth arrest, but far less is known about pathways that regulate the SASP. We pr...

V79 lung fibroblasts were subjected to repetitive oxidative stress in culture through exposures to 30 microM H(2)O(2) for 4 weeks. Repetitively stressed cells were found to be significantly resistant to apoptosis-inducing agent such as ultraviolet radiation (UVR). Concurrent treatment with Resveratrol completely restored the normal apoptotic response after UVR. p38MAPK became dually phosphoryla...

p38MAPK (MAPK14) is a well-studied stress kinase that transmits numerous extracellular signals and is involved in multiple cellular processes. The role of p38MAPK has been rigorously investigated in many pathophysiological conditions including cancer. Originally proposed as a potential cancer suppressor [1, 2], the role of p38MAPK in tumorigenesis however remained controversial. Among the reaso...

BACKGROUND Endothelial nitric oxide synthase (eNOS)-uncoupling links obesity-associated insulin resistance and type-II diabetes to the increased incidence of cardiovascular disease. Studies have indicated that increased arginase is involved in eNOS-uncoupling through competing with the substrate L-arginine. Given that arginase-II (Arg-II) exerts some of its biological functions through crosstal...

Immunological mediators that originate outside the nervous system can affect neuronal health. However, their roles in neurodegeneration remain largely unknown. Here, we show that the p38MAPK-mediated immune pathway activated in intestinal cells of Caenorhabditis elegans upon mitochondrial dysfunction protects neurons in a cell-non-autonomous fashion. Specifically, mitochondrial complex I dysfun...

BACKGROUND The signaling pathways that may modulate the pathogenesis of diseases induced by expanded polyglutamine proteins are not well understood. METHODOLOGIES/PRINCIPAL FINDINGS Herein we demonstrate that expanded polyglutamine protein cytotoxicity is mediated primarily through activation of p38MAPK and that the atypical PKC iota (PKCiota) enzyme antagonizes polyglutamine-induced cell dea...

Hydrogen sulfide (H(2)S) has been proposed as a novel neuromodulator and neuroprotective agent. Cobalt chloride (CoCl(2)) is a well-known hypoxia mimetic agent. We have demonstrated that H(2)S protects against CoCl(2)-induced injuries in PC12 cells. However, whether the members of mitogen-activated protein kinases (MAPK), in particular, extracellular signal-regulated kinase1/2(ERK1/2) and p38MA...
