Angiotensin II-induced Apoptosis in Vascular Smooth Muscle Cells: Differential Effects in Human Saphenous Vein and Human Internal Mammary Artery
… Protein expression of Bax, Bcl-2, and phospho-p38 MAP kinase was examined by Western Blot. The data revealed three major findings: (1) Angiotensin II induced significant apoptosis in VSMCs of the SV following 8 hours of treatment, whereas there was no pro- apoptotic effect of angiotensin II on …

The effects of statins on hypoxia-induced proliferation and cell signalling pathways in pulmonary artery fibroblasts
… specific and dependant on phosphorylation of p38 mitogen-activated protein (MAP) kinase, the cell signalling pathway(s)underlying this are incompletely characterised. Hypoxic activation of PAFs is a potential therapeutic target but, as p38 MAP kinase inhibitors are not established for clinical …

Regulation Of Apoptotic Alkalinization Through Phosphorylation Of Sodium Hydrogen Exchanger Via P38 Mitogen Activated Protein Kinase
… whose activity is regulated by the stress kinase p38 MAPK. In previous studies, upon cytokine withdrawal from cytokine-dependent lymphocytes induced the activity of the p38 MAP kinase which then phosphorylated the C-terminus of NHE1. To identify the p38 MAPK phosphorylation sites on NHE1, …

Intramyokardiale Expression von COX-2 und TNF[alpha] in Abhängigkeit von der Kerntemperatur bei Herzoperationen mit extrakorporalem Kreislauf : eine tierexperimentelle Untersuchung
… This was associated with a lower activation of p38-MAP-kinase and AP-1 in hypothermic treated animals. NFkB acts completely different by showing no distinction between the both testing groups. The results of this investigation show that by means of moderate hypothermia during the cardiopulmonary …

TIMP-1: Zelluläre Funktion und Beeinflussung der Genexpression von Matrix-Metalloproteinasen in humanen Hepatomzellen
… by TIMP-1. For this purpose both certain kinases as well as their phosphorylated form (STAT 1, P-STAT 1, STAT 3, P-STAT-3, JAK 1, P-JAK 1, JAK 2, P-JAK 2, Ras GAP and JNK 1) were investigated by means of western blot analysis and western blot analysis after immunoprecipitation in wild type …

Expression of Human Estrogen Receptor and Studies of Estrogen-Mediated Transcription and Apoptosis
… transfections and a reporter system to measure p38 activity, we show that E2 induces the p38 activity 12--36 fold in several ER positive cell lines, while OHT induces p38 activity 2--5 fold. A selective inhibitor of p38 MAP kinase, S13 203580, partially protects HeLa-ER5 cells against apoptosis …

Regulation of mRNA expression through 3’ UTR sequences of IL6 gene in amino acid-deprived HeLa cells
… of p65, NF-κB subunit. Finally, treatments of p38 MAP kinase inhibitor, SB203580 markedly blocked mRNA stabilization through 3’UTR as well as IL6 induction after amino acid-starvation, suggesting that p38-MK2/3-TTP pathway is evidently activated and implicated in stabilization of IL6 mRNA …

HIV Tat Protein Activates Endothelial Cells through NFκB and MAP Kinase Pathways.
… TNFα). Cell lysate fractions were analyzed for MAP Kinase activity and NFκB activation, and culture supernatants were assayed for inflammatory cytokines (IL-6 and IL-8). The production of IL-6 and IL-8 was significantly enhanced by tat but not by gp120. Both gp120 and tat, however, induced …

Influences of nutrition and pathogenicity from a microbial diet on immunity and longevity in Caenorhabditis elegans
… response to pathogenic bacteria downstream of p38 MAP Kinase signaling. In Chapter Four, I present ideas for exploring the future directions of these two projects that focus on untangling how C. elegans respond to a changing microbial environment.
