Evaluation of fatty acid amide hydrolase (FAAH) as a target for osteoarthritic pain in humans, using an integrated systems pharmacology model.
The SBML version of the model is obtained from the supplementary material of the corresponding paper (see below).

Abstract:
The level of the endocannabinoid anandamide is controlled by fatty acid amide hydrolase (FAAH). In 2011, PF-04457845, an irreversible inhibitor of FAAH, was progressed to phase II clinical trials for osteoarthritic pain. This article discusses a prospective, integrated systems pharmacology model evaluation of FAAH as a target for pain in humans, using physiologically based pharmacokinetic and systems biology approaches. The model integrated physiological compartments; endocannabinoid production, degradation, and disposition data; PF-04457845 pharmacokinetics and pharmacodynamics, and cannabinoid receptor CB1-binding kinetics. The modeling identified clear gaps in our understanding and highlighted key risks going forward, in particular relating to whether methods are in place to demonstrate target engagement and pharmacological effect. The value of this modeling exercise will be discussed in detail and in the context of the clinical phase II data, together with recommendations to enable optimal future evaluation of FAAH inhibitors.

Project description:FAAH expresson is induced in Sle2 splenic B cells. Increased peripheral B cell receptor revision, or selective peripheral expansion of BCR-revised B-cells, may lead to systemic autoimmunity, and FAAH is a lupus susceptibility gene that could regulate this process in Sle2 mice.

Project description:FAAH expresson is induced in Sle2 splenic B cells. Increased peripheral B cell receptor revision, or selective peripheral expansion of BCR-revised B-cells, may lead to systemic autoimmunity, and FAAH is a lupus susceptibility gene that could regulate this process in Sle2 mice. To determine the gene expression profile in peripheral B cells from Sle2 mice (compared to B6 mice), we isolated splenic B cells from these two strains of mice, extracted the total mRNA and performed the microarray analysis Please note that Sle2 mouse is a congenic strain that harbors the Sle2 locus from Chromosome 4 of NZM2410 strain in a B6 background and Sle2 is the name of the lupus susceptibility locus.

Project description:We evaluated cutaneous contact hypersensitivity (CHS) in Cnr1-/-/Cnr2-/- animals using the obligate contact allergen 2,4-dinitrofluorobenzene (DNFB), which generates a specific cutaneous T-cell mediated allergic response upon repeated allergen contact. Allergic contact dermatitis affects about 5% of men and 11% of women in industrialized countries and is one of the leading causes for occupational diseases. In an animal model for cutaneous contact hypersensitivity we show that mice lacking both known cannabinoid receptors display exacerbated allergic inflammation. In contrast, fatty acid amide hydrolase deficient mice, which have increased levels of the endocannabinoid anandamide, displayed reduced allergic responses in the skin. Cannabinoid receptor antagonists exacerbated whereas receptor agonists attenuated allergic inflammation. These results demonstrate a protective role of the endocannabinoid system in contact allergy in the skin, and suggest a novel target for therapeutic intervention. Experiment Overall Design: Three wildtype mice (Wt) and three Cnr1-/-/Cnr2-/- (Ko) mice were used. Contact hypersensitivity was determined always at the right ears, which therefore were treated with DNFB (Tr). Left ears of mice were kept untreated and served as control ears (C). A total of 12 hybridizations were performed (2 strains x 2 treatments X 3 biological replicates) in this experiment.

Project description:Fatty acid amide hydrolase (FAAH) is an important enzyme for lipid metabolism and an interesting pharmacological target, given its role in anandamide breakdown. The FAAH-/- genotype is the most widely used mouse model to achieve complete abolition of this enzyme. In this paper we explore, by means of label-free SWATH proteomics, the changes in protein expression occurring in the liver of FAAH-/- mice. We identified several altered biological processes and pathways, like fatty acid synthesis and glycolysis, which explain the observed phenotype of this mouse. We also observed the alteration of other proteins, like carboxylesterases and S-methyltransferases, apparently not immediately related to FAAH, but known to have important biological roles.

Project description:The endocannabinoid system is considered to be an endogenous protective system in various neurodegenerative diseases. Niemann-Pick Type C is a neurodegenerative disease in which the role of the endocannabinoid system has not been studied yet. Here, we report the endocannabinoid hydrolase activity in brain proteomes of a Niemann-Pick type C mouse model as measured by activity-based protein profiling. Diacylglycerol lipase α, α/β-hydrolase domain-containing protein 4 (ABHD4), ABHD6, ABHD12, fatty acid amide hydrolase and monoacylglycerol lipase activities were quantified. Chemical proteomics showed no difference in endocannabinoid hydrolase activity in the brain of wildtype compared to Niemann-Pick C1 protein (NPC1) knockout mice. Three lysosomal serine hydrolases were identified with increased activity in NPC1 knockout mouse brain: retinoid-inducible serine carboxypeptidase, cathepsin A and palmitoyl-protein thioesterase 1, and we conclude that these might be interesting therapeutic targets for future validation studies.
