DDC feeding in

OPN and TNFR1 knock-out mice and respective WT controls resulted in comparable extent of liver injury, inflammatory response, ductular reaction and liver fibrosis. Our data indicate that genetic loss of neither OPN nor TNFR1 significantly effects on the pathogenesis of DDC-induced sclerosing cholangitis, ductular reaction and resulting biliary fibrosis.

“Intrathecal (i.t.) injection of AM251, a cannabinoid 1 (CB(1)) receptor antagonist, into the spinal lumbar space of mice elicited a behavioral response consisting of biting and licking with a few scratchings. In this study, we investigated to Ispinesib manufacturer determine whether i.t. AM251 could influence the activity of extracellular signal-regulated kinase-1 and -2 (ERK1/2), a mitogen-activated protein kinase (MAPK) in neuronal nitric oxide synthase (nNOS)

and inducible NOS (iNOS) activation. The CB(1) receptor agonist ACEA, neurokinin 1 (NK(1)) receptor antagonists and NMDA receptor antagonists, inhibited it. AM251-induced behavioral response in a dose-dependent manner. The CB(2) receptor agonist, JWH-133 gave no effect on response elicited by i.t. AM251. Both non-selective NOS inhibitors, L-NAME and 7-NI, and N(omega)-propyl-L-arginine, a selective inhibitor of nNOS resulted in a dose-dependent JQ1 price inhibition of i.t. AM251-induced

behavioral response. The selective iNOS inhibitor, 1400W, in relatively large doses, Cell Cycle inhibitor inhibited in a non dose-dependent manner. The i.t. injection of AM251 produced a definite activation of ERK1/2 in the lumbar dorsal spinal cord. Behavioral experiments showed that U0126, a MAPK/ERK kinase (MEK) inhibitor, dose-dependently attenuated the behavioral response to i.t. AM251. Spinal activation of ERK1/2 following i.t. AM251 was reduced clearly by N(omega)-propyl-L-arginine and U0126, while 1400W gave a significant effect on only ERK1 activation. These findings suggest that the nNOS-ERK pathway in spinal cord neurones plays an important role in AM251-induced nocifensive behavior and its inhibition may provide significant anti-nociception.
