Regulation of kindling epileptogenesis by hippocampal galanin type 1 and type 2 receptors: The effects of subtype-selective agonists and the role of G-protein-mediated signaling.[Pubmed:16699066]

J Pharmacol Exp Ther. 2006 Aug;318(2):700-8.

The search for antiepileptic drugs that are capable of blocking the progression of epilepsy (epileptogenesis) is an important problem of translational epilepsy research. The neuropeptide galanin effectively suppresses acute seizures. We examined the ability of hippocampal galanin receptor type 1 (GalR1) and type 2 (GalR2) to inhibit kindling epileptogenesis and studied signaling cascades that mediate their effects. Wistar rats received 24-h-long intrahippocampal infusion of a GalR1/2 agonist galanin(1-29), GalR1 agonist M617 [galanin(1-13)-Gln14-bradykinin(2-9)-amide], or GalR2 agonist galanin(2-11). The peptides were administered alone or combined with an inhibitor of Gi protein pertussis toxin (PTX), Gi-protein activated K+ channels (GIRK) inhibitor tertiapin Q (TPQ), G(q/11) protein inhibitor [D-Arg1,D-Trp(5,7,9),Leu11]-substance P (dSP), or an inhibitor of intracellular Ca2+ release dantrolene. Sixteen hours into drug delivery, the animals were subjected to rapid kindling-60 electrical trains administered to ventral hippocampus every 5 min. M617 delayed epileptogenesis, whereas galanin(1-29) and galanin(2-11) completely prevented the occurrence of full kindled seizures. TPQ abolished anticonvulsant effect of M617 but not of galanin(2-11). PTX blocked anticonvulsant effects of M617 and inversed the action of galanin(1-29) and galanin(2-11) to proconvulsant. dSP and dantrolene did not modify seizure suppression through GalR1 and GalR2, but eliminated the proconvulsant effect of PTX + galanin(1-29) and PTX + galanin(2-11) combinations. We conclude that hippocampal GalR1 exert their disease-modifying effect through the Gi-GIRK pathway. GalR2 is antiepileptogenic through the Gi mechanism independent of GIRK. A secondary proconvulsant pathway coupled to GalR2 involves G(q/11) and intracellular Ca2+. The data are important for understanding endogenous mechanisms regulating epileptogenesis and for the development of novel antiepileptogenic drugs.

DUB-2 is a member of a novel family of cytokine-inducible deubiquitinating enzymes.[Pubmed:8995226]

J Biol Chem. 1997 Jan 3;272(1):51-7.

Cytokines regulate cell growth by inducing the expression of specific target genes. We have recently identified a cytokine-inducible, immediate-early gene, DUB-1, that encodes a deubiquitinating enzyme with growth regulatory activity. In the current study, we have isolated a highly related gene, DUB-2, that is induced by interleukin-2. The DUB-2 mRNA was induced in T cells as an immediate-early gene and was rapidly down-regulated. Like DUB-1, the DUB-2 protein had deubiquitinating activity in vitro. When a conserved cysteine residue of DUB-2, required for ubiquitin-specific thiol protease activity, was mutated to serine (C60S), deubiquitinating activity was abolished. DUB-1 and DUB-2 proteins are highly related throughout their primary amino acid sequence except for a hypervariable region at their COOH terminus. Moreover, the DUB genes co-localize to a region of mouse chromosome 7, suggesting that they arose by a tandem duplication of an ancestral DUB gene. Additional DUB genes co-localize to this region, suggesting a larger family of cytokine-inducible DUB enzymes. We propose that different cytokines induce specific DUB genes. Each induced DUB enzyme thereby regulates the degradation or the ubiquitination state of an unknown growth regulatory factor, resulting in a cytokine-specific growth response.
