Abstract

The widely used plasticiser di(2-ethylhexyl)phthalate (DEHP) has been reported to have some toxicological effects on pulmonary tissue. Inhalation of DEHP may cause pulmonary edema and bronchial asthma. Moreover intravenous injection of DEHP induces pulmonary inflammation and hemorrhage of the lungs. We now report that DEHP might cause bronchial hyperresponsiveness. The metabolite of DEHP mono(2-ethylhexyl)phthalate (MEHP) induces in vitro a dose-dependent increase in -log EC50 for methacholine dose response curves in rat tracheal tissue. Moreover MEHP induces a decrease in maximal effect of the methacholine dose response curve. We concluded that DEHP due to the formation of MEHP in vivo, may cause bronchial hyperresponsiveness.

Rho kinase activation plays a major role as a mediator of irreversible injury in reperfused myocardium.

Intracellular signal transduction events in reperfusion following ischemia influence myocardial infarct development. Here we investigate the role of Rho kinase (ROCK) activation as a specific injury signal during reperfusion via attenuation of the reperfusion injury salvage kinase (RISK) pathway phosphatidylinositol 3-kinase (PI3K)/Akt/endothelial nitric oxide (NO) synthase (eNOS). Rat isolated hearts underwent 35 min of left coronary artery occlusion and 120 min of reperfusion. Phosphorylation of the ROCK substrate protein complex ezrin-radixin-moesin, assessed by immunoblotting and immunofluorescence, was used as a marker of ROCK activation. Infarct size was determined by tetrazolium staining, and terminal dUTP nick-end labeling (TUNEL) positivity was used as an index of apoptosis. The ROCK inhibitors fasudil or Y-27632 given 10 min before ischemia until 10 min after reperfusion reduced infarct size (control, 34.1 +/- 3.8%; 5 microM fasudil, 18.2 +/- 3.1%; 0.3 microM Y-27632, 19.4 +/- 4.4%; 5 microM Y-27632, 9.2 +/- 2.9%). When 5 microM Y-27632 was targeted specifically during early reperfusion, robust infarct limitation was observed (14.2 +/- 2.6% vs. control 33.4 +/- 4.4%, P<0.01). The protective action of Y-27632 given at reperfusion was attenuated by wortmannin (29.2 +/- 6.1%) and N(omega)-nitro-L-arginine methyl ester (30.4 +/- 5.7%), confirming a protective mechanism involving PI3K/Akt/NO. Ezrin-radixin-moesin phosphorylation in risk zone myocardium confirmed early and sustained ROCK activation during reperfusion and its inhibition by Y-27632. Inhibition of ROCK activation at reperfusion reduced the proportion of TUNEL-positive nuclei in the infarcted region. In conclusion, ROCK activation occurs specifically during early reperfusion. Inhibition of ROCK at reperfusion onset limits infarct size through an Akt/eNOS-dependent mechanism, suggesting that ROCK activation at reperfusion may be deleterious through suppression of the RISK pathway.

Post-translational synaptic protein modification as substrate for long-lasting, remote memory: an initial test.

The current view of the molecular basis for information storage is that post-translational modification (PTM) of brain proteins is important for the early stages of memory storage and that protein synthesis is necessary for long-lasting memory. This view has been challenged by the proposal that PTM of synaptic proteins is the critical instructive mechanism underlying both recent as well as long-lasting memories (Routtenberg and Rekart, 2005). As an initial test, a broad spectrum serine/threonine kinase inhibitor (H-7) was delivered bilaterally to rat anterior cingulate cortex 1 h before a 3 week retention test of contextual fear conditioning. This significantly blocked 21-Day retention. In the second experiment evaluating extinction of a 21-Day remote memory, H-7 injected into mouse medial prefrontal cortex blocked fear extinction. As the H-7-induced impairment in 21-Day retention was indexed by a decrease in freezing, while the extinction blockade by no decrease in freezing, the results could not be ascribed to a direct effect of the drug on behavioral performance. This represents the first demonstration, to our knowledge, that PTM inhibition, here serine/threonine kinase activity, interferes with long-lasting memory, providing initial support for the PTM model.

Diverse signaling pathways regulate fibroblast differentiation and transformation through Rho kinase activation.

This study examined the role of agonist-induced Rho kinase (ROCK) involvement in the morphological outcome of pulmonary-derived fibroblasts. Normal human lung fibroblasts (NHLF) spontaneously differentiate into network-like structures in a two-dimensional growth factor reduced Matrigel matrix-based assay. Sphingosine 1-phosphate (SPP), a bioactive phospholipid that regulates angiogenesis, inhibited fibroblast morphogenesis in a dose-dependent manner, virtually eliminating the presence of multi-cellular structures at 500 nM. Pretreatment with the Rho kinase-specific inhibitor, H1152, eradicated the high dose SPP-induced inhibition. Similarly, NHLFs transfected with Rho kinase siRNA prevented SPP-induced inhibition of the fibroblast morphogenesis. Alternatively, transforming growth factor-beta1 (TGF-beta1), a cytokine recognized as a key mediator of wound healing, terminally differentiates NHLF into myofibroblasts as evidenced by the expression of the smooth muscle cell isoform of alpha-actin (alpha-SMA). H1152 suppressed TGF-beta1-induced alpha-SMA expression in a dose-dependent manner. Similarly, treatment with Rho kinase siRNA reduced alpha-SMA expression by greater than 50%. SPP treatment had no effect on TGF-beta1-induced transformation into myofibroblasts, and TGF-beta1 treatment did not alter fibroblast morphogenesis. This study suggests a dual regulatory role for Rho kinase in cellular regulation of fibroblasts in which SPP-induced Rho kinase activation via a G-protein coupled receptor suppresses fibroblast morphogenesis while TGF-beta1-induced Rho kinase activation through a serine/threonine kinase receptor culminates in transformation into myofibroblasts.
