مستخلص: The origins and evolution of higher cognitive functions, including complex forms of learning, attention and executive functions, are unknown. A potential mechanism driving the evolution of vertebrate cognition early in the vertebrate lineage (550 million years ago) was genome duplication and subsequent diversification of postsynaptic genes. Here we report, to our knowledge, the first genetic analysis of a vertebrate gene family in cognitive functions measured using computerized touchscreens. Comparison of mice carrying mutations in each of the four Dlg paralogs showed that simple associative learning required Dlg4, whereas Dlg2 and Dlg3 diversified to have opposing functions in complex cognitive processes. Exploiting the translational utility of touchscreens in humans and mice, testing Dlg2 mutations in both species showed that Dlg2's role in complex learning, cognitive flexibility and attention has been highly conserved over 100 million years. Dlg-family mutations underlie psychiatric disorders, suggesting that genome evolution expanded the complexity of vertebrate cognition at the cost of susceptibility to mental illness.

مستخلص: We conducted a genome-wide association study for primary open-angle glaucoma (POAG) in 1,263 affected individuals (cases) and 34,877 controls from Iceland. We identified a common sequence variant at 7q31 (rs4236601[A], odds ratio (OR) = 1.36, P = 5.0 × 10−10). We then replicated the association in sample sets of 2,175 POAG cases and 2,064 controls from Sweden, the UK and Australia (combined OR = 1.18, P = 0.0015) and in 299 POAG cases and 580 unaffected controls from Hong Kong and Shantou, China (combined OR = 5.42, P = 0.0021). The risk variant identified here is located close to CAV1 and CAV2, both of which are expressed in the trabecular meshwork and retinal ganglion cells that are involved in the pathogenesis of POAG.

مستخلص: Disrupted-in-Schizophrenia-1 (DISC1), identified by positional cloning of a balanced translocation (1;11) with the breakpoint in intron 8 of a large Scottish pedigree, is associated with a range of neuropsychiatric disorders including schizophrenia. To model this mutation in mice, we have generated Disc1
tr transgenic mice expressing 2 copies of truncated Disc1 encoding the first 8 exons using a bacterial artificial chromosome (BAC). With this partial simulation of the human situation, we have discovered a range of phenotypes including a series of novel features not previously reported. Disc1tr transgenic mice display enlarged lateral ventricles, reduced cerebral cortex, partial agenesis of the corpus callosum, and thinning of layers II/III with reduced neural proliferation at midneurogenesis. Parvalbumin GABAergic neurons are reduced in the hippocampus and medial prefrontal cortex, and displaced in the dorsolateral frontal cortex. In culture, transgenic neurons grow fewer and shorter neurites. Behaviorally, transgenic mice exhibit increased immobility and reduced vocalization in depression-related tests, and impairment in conditioning of latent inhibition. These abnormalities in Disc1tr transgenic mice are consistent with findings in severe schizophrenia.

مستخلص: Breen G, Harwood AJ, Gregory K, Sinclair M, Collier D, St Clair D, Williams RSB. Two peptidase activities decrease in treated bipolar disorder not schizophrenic patients. Bipolar Disord 2004: 6: 156–161. © Blackwell Munksgaard, 2004 Inhibition of prolyl oligopeptidase (PO) in primary neuronal cultures has been shown to reverse the effect of the common mood-stabilizers lithium, valproic acid and carbamazepine. In clinical studies, abnormal plasma PO activity has been associated with bipolar disorder (BD) and schizophrenia. However, this association is complicated by the discovery in bovine plasma of a Z-Pro-prolinal-insensitive peptidase (ZIP), a novel enzyme that cleaves the same substrate as PO. We developed an assay to distinguish between ZIP and PO and measured both activities in plasma from 48 BD and 50 schizophrenic patients undergoing treatment and compared them with 50 control subjects. ZIP activity is restricted to blood plasma, whereas PO activity is present in the cytosol of lymphocytes, but can also be detected in blood plasma. Significant decreases in their plasma activities were found between treated BD (p = 0.007 and 0.03 respectively) but not schizophrenic (p > 0.05) patients and controls. We have found that the enzyme activity previously reported as plasma PO actually comprises two enzymes, PO and ZIP. This study shows a statistically significant decrease of both enzymes in BD patients undergoing lithium treatment. No statistically significant change in PO or ZIP activity is observed in schizophrenic patients. [ABSTRACT FROM AUTHOR]
