Prostaglandin endoperoxide synthase (PGHS; cyclooxygenase), the rate-limiting enzyme in the conversion of arachidonic acid to prostanoids, has two isoforms. PGHS-1 is constitutively expressed and involved in homeostasis, whereas PGHS-2 is inducible in monocytes in response to proinflammatory agents. Using freshly
The signaling pathways that may modulate the pathogenesis of diseases induced by expanded polyglutamine proteins are not well understood. Herein we demonstrate that expanded polyglutamine protein cytotoxicity is mediated primarily through activation of p38MAPK and that the atypical PKC iota
The elucidation of the molecular mechanisms governing the transition from a nonangiogenic to an angiogenic phenotype is central for understanding and controlling malignancies. Viral oncogenes represent powerful tools for disclosing transforming mechanisms, and they may also afford the possibility of
Activation of the Na+/H+ exchanger isoform-1 (NHE-1) by angiotensin II is an early signal transduction event that may regulate vascular smooth muscle cell (VSMC) growth and migration. Many signal transduction events stimulated by angiotensin II are mediated by the mitogen-activated
p38 MAPK has been implicated in the response to cancer therapy. To determine whether the activation of p38 MAPK could be specific to cancer therapy, we investigated the activation of p38 MAPK in response to several chemotherapeutic agents, such as
