(COMT) Gene As a Candidate for Psychiatric Phenotypes
Molecular Psychiatry (2006) 11, 446–458 & 2006 Nature Publishing Group All rights reserved 1359-4184/06 $30.00 www.nature.com/mp FEATURE REVIEW The catechol-O-methyl transferase (COMT) gene as a candidate for psychiatric phenotypes: evidence and lessons N Craddock, MJ Owen and MC O’Donovan Department of Psychological Medicine, The Henry Wellcome Building for Biomedical Research in Wales, Cardiff University, School of Medicine, Heath Park, Cardiff, UK The enzyme catechol-O-methyl transferase (COMT), identified in the 1950s, is involved in catabolism of monoamines that are influenced by psychotropic medications, including neuroleptics and antidepressants. The COMT gene lies in a chromosomal region of interest for psychosis and bipolar spectrum disorder and a common polymorphism within the gene alters the activity of the enzyme. As a consequence, COMT has been one of the most studied genes for psychosis. On the basis of prior probabilities it would seem surprising if functional variation at COMT did not have some influence either on susceptibility to psychiatric phenotypes, modification of the course of illness or moderation of response to treatment. There is now robust evidence that variation at COMT influences frontal lobe function. However, despite considerable research effort, it has not proved straightforward to demonstrate and characterise a clear relationship between genetic variation at COMT and psychiatric phenotypes. It is of course, possible that COMT will turn out to be an unusually intractable case but it seems more likely that the experiences with this gene will provide a foretaste of the complexity of genotype–phenotype relationships that will be found for psychiatric traits. -

Hence, the mechanistic understanding of the tumor metastasis and chemotherapy resistance is quietly important. Methods: TCGA database and clinical samples are used for exploring the role of FHL3 in disease progression and prognosis. The roles of FHL3 in metastasis and chemotherapy resistance are explored in vitro and in vivo by siRNA or shRNA treatment. Finally, we explore the FHL3-mediated EMT and chemotherapy resistance. Results: mRNA and protein level of FHL3 is signicantly up-regulated in gastric cancer tissues when compares with it in adjacent tissue. -

Impaired efferocytosis drives the formation of clinically dangerous necrotic atherosclerotic plaques, the underlying etiology of coronary artery disease (CAD). An intron of the gene encoding PHACTR1 contains a common variant rs9349379 (A > G) associated with CAD. -

In the articles, the protein was referred to as ‘SAP130, a subunit of the histone deacetylase complex.’ However, the Mincle ligand the authors aimed to investigate is splicing factor 3b subunit 3 (SF3B3). This splicing factor is unrelated to SAP130 (Sin3A associated protein 130, a subunit of the histone deacetylase-dependent Sin3A corepressor complex). The conclusions in the three articles were formulated for SF3B3, Citation: Metselaar, P.I.; Hos, C.; while the researchers used qPCR primers and antibodies against SAP130. -

REPORT Germline Mutation of INI1/SMARCB1 in Familial Schwannomatosis
REPORT Germline Mutation of INI1/SMARCB1 in Familial Schwannomatosis Theo J. M. Hulsebos, Astrid S. Plomp, Ruud A. Wolterman, Els C. Robanus-Maandag, Frank Baas, and Pieter Wesseling Patients with schwannomatosis develop multiple schwannomas but no vestibular schwannomas diagnostic of neurofi- bromatosis type 2. We report an inactivating germline mutation in exon 1 of the tumor-suppressor gene INI1 in a father and daughter who both had schwannomatosis. Inactivation of the wild-type INI1 allele, by a second mutation in exon 5 or by clear loss, was found in two of four investigated schwannomas from these patients. All four schwannomas displayed complete loss of nuclear INI1 protein expression in part of the cells. Although the exact oncogenetic mechanism in these schwannomas remains to be elucidated, our findings suggest that INI1 is the predisposing gene in familial schwannomatosis. Schwannomatosis (MIM 162091) is characterized by the 10 Only two families with an INI1 germline mutation, an development of multiple spinal, peripheral, and cranial- exon 4 frameshift mutation,11 and an exon 7 donor splice nerve schwannomas in the absence of vestibular schwan- site mutation12 have been described in which multiple nomas.1 The presence of vestibular schwannomas is di- generations were affected by malignant (rhabdoid) tumors agnostic of neurofibromatosis type 2 (NF2 [MIM 101000]). in infancy.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

In this work we present a comprehensive study of quantitative anomalies at chromosome 17 by genomic array- most attention (6–10). Furthermore, DNA microarray studies have comparative genomic hybridization and of associated RNA expression revealed additional candidates, with some located outside current changes by cDNA arrays. We built a genomic array covering the entire regions of gains, thus suggesting the existence of additional amplicons chromosome at an average density of 1 clone per 0.5 Mb, and patterns of on 17q (8, 9). gains and losses were characterized in 30 breast cancer cell lines and 22 Our previous loss of heterozygosity mapping data pointed to the primary tumors. -
