The CCDC55 couples cannabinoid receptor CNR1 to a putative DISC1 schizophrenia pathway.
Stockholm, Sweden. In Neuroscience, 03 Jan 2016
PRINCIPAL FINDINGS: (i) CCDC55 is expressed as a nuclear protein in human neuronal cells; (ii) Protein-protein interaction analyses showed CCDC55 physically interacted with Ran binding protein 9 (RanBP9) and disrupted in schizophrenia 1 (DISC1); (iii) CCDC55 and RanBP9 co-localized in the nucleus of human neuronal cells; (iv) CCDC55 also interacted with the cannabinoid receptor 1 (CNR1), and with the brain cannabinoid receptor-interacting protein 1a (CNRIP1a); (v) CNR1 activation in differentiated human neuronal cells resulted in an altered RanBP9 localization.
Schizophrenia and Depression Co-Morbidity: What We have Learned from Animal Models.
Toronto, Canada. In Front Psychiatry, Dec 2014
Current models which demonstrate endophenotypes of both schizophrenia and depression are reviewed here, including models of CUB and SUSHI multiple domains 1, PDZ and LIM domain 5, glutamate Delta 1 receptor, diabetic db/db mice, neuropeptide Y, disrupted in schizophrenia 1, and its interacting partners, reelin, maternal immune activation, and social isolation.
Synaptic dysregulation in a human iPS cell model of mental disorders.
Baltimore, United States. In Nature, Dec 2014
Here we generated induced pluripotent stem (iPS) cells from four members of a family in which a frameshift mutation of disrupted in schizophrenia 1 (DISC1) co-segregated with major psychiatric disorders and we further produced different isogenic iPS cell lines via gene editing.
