Group I metabotropic glutamate receptors (mGluR1 and mGluR5 subtypes) are regulated by protein kinases. A recent focus is mitogen-activated protein kinases (MAPK). A prototypic subclass of MAPKs, extracellular signal-regulated kinases (ERK), is densely expressed in adult brain postmitotic neurons. This kinase resides in not only the cytoplasm around the nucleus, also the neuronal peripheral str...
Lipopolysaccharide (LPS) induces acute lung injury (ALI) via Toll-like receptor 4 (TLR4)-mediated MAPK activation. The lipid A fraction of LPS is considered to be the active moiety, but whether the lipid A-TLR4 interaction accounts completely for ALI-associated MAPK activation in vivo has not been determined. The lipid A fraction of LPS induces a discrete MAPK activation pattern in murine ALI. ...
Pressure overload-induced cardiac hypertrophy results in a pathological type of hypertrophy with activation of signaling cascades like the extracellular signal-regulated kinase (ERK) pathway, which promotes negative cardiac remodeling and decreased contractile function. In contrast, thyroid hormone mediates a physiological type of hypertrophy resulting in enhanced contractile function. In addit...
Fear-conditioned analgesia (FCA) is the reduction in pain responding which is expressed upon re-exposure to a context previously paired with an aversive stimulus. Projections along the prefrontal cortex (PFC)-amygdala-dorsal periaqueductal grey (dPAG) pathway may mediate FCA. However, there is a paucity of studies measuring both molecular and electrophysiological changes in this pathway in rats...
Psychologic distress is associatedwith increased lung cancer incidence andmortality.Wehave shown that non–small cell lung cancer (NSCLC) cells in vitro are stimulated by the cyclic AMP (cAMP)-dependent activation of cAMP-responsive element binding protein (CREB) and extracellular signal–regulated kinase (ERK) downstream of b-adrenergic receptors and that this pathway is inhibited by the neurotr...
BACKGROUND We demonstrated that oxidative stress plays a crucial role in cognitive impairment in klotho mutant mice, a genetic model of aging. Since down-regulation of melatonin due to aging is well documented, we used this genetic model to determine whether the antioxidant property of melatonin affects memory impairment. METHODS First, we examined the effects of melatonin on hippocampal oxid...
Recent studies suggest that aldosterone-mediated sulfenic acid modification of the endothelin B receptor (ETB) promotes renal injury in an ischemia/reperfusion model through reduced ETB-stimulated nitric oxide production. Similarly, aldosterone inactivation of ETB signaling promotes pulmonary artery hypertension. Consequently, we asked whether aldosterone inhibits collecting duct ETB signaling;...
Tanshinone IIA (Tan-IIA) is extracted from Danshen (Salviae miltiorrhizae radix). It possesses antitumor activity against a variety of human cancer cells and its induction of apoptosis and inhibition of proliferation of gastric cancer cells are well-documented. However, the molecular mechanisms by which Tan-IIA inhibits gastric cancer have not been well-elucidated. In the present study, we eval...
Psychologic distress is associated with increased lung cancer incidence and mortality. We have shown that non-small cell lung cancer (NSCLC) cells in vitro are stimulated by the cyclic AMP (cAMP)-dependent activation of cAMP-responsive element binding protein (CREB) and extracellular signal-regulated kinase (ERK) downstream of β-adrenergic receptors and that this pathway is inhibited by the neu...
