Question: Cadherin-mediated cell-cell adhesion is required for epithelial tissue integrity in homeostasis, during development, and in tissue repair. E-cadherin stability depends on F-actin, but the mechanisms regulating actin polymerization at cell-cell junctions remain poorly understood. Here we investigated a role for formin-mediated actin polymerization at cell-cell junctions. We identify mDia1 and Fmnl3 as major factors enhancing actin polymerization and stabilizing E-cadherin at epithelial junctions. Fmnl3 localizes to adherens junctions downstream of Src and Cdc42 and its depletion leads to a reduction in F-actin and E-cadherin at junctions and a weakening of cell-cell adhesion. Of importance, Fmnl3 expression is up-regulated and junctional localization increases during collective cell migration. Depletion of Fmnl3 or mDia1 in migrating monolayers results in dissociation of leader cells and impaired wound repair. In summary, our results show that formin activity at epithelial cell-cell junctions is important for adhesion and the maintenance of epithelial cohesion during dynamic processes, such as wound repair.

Answer: Formin-mediated actin polymerization at cellcell junctions stabilizes E-cadherin and maintains monolayer integrity during wound repair

Question: BackgroundBy comparing the quail genome with that of chicken, chromosome rearrangements that have occurred in these two galliform species over 35 million years of evolution can be detected. From a more practical point of view, the definition of conserved syntenies helps to predict the position of genes in quail, based on information taken from the chicken sequence, thus enhancing the utility of this species in biological studies through a better knowledge of its genome structure. A microsatellite and an Amplified Fragment Length Polymorphism (AFLP) genetic map were previously published for quail, as well as comparative cytogenetic data with chicken for macrochromosomes. Quail genomics will benefit from the extension and the integration of these maps. ResultsThe integrated linkage map presented here is based on segregation analysis of both anonymous markers and functional gene loci in 1,050 quail from three independent F2 populations. Ninety-two loci are resolved into 14 autosomal linkage groups and a Z chromosome-specific linkage group, aligned with the quail AFLP map. The size of linkage groups ranges from 7.8 cM to 274.8 cM. The total map distance covers 904.3 cM with an average spacing of 9.7 cM between loci. The coverage is not complete, as macrochromosome CJA08, the gonosome CJAW and 23 microchromosomes have no marker assigned yet. Significant sequence identities of quail markers with chicken enabled the alignment of the quail linkage groups on the chicken genome sequence assembly. This, together with interspecific Fluorescence In Situ Hybridization (FISH), revealed very high similarities in marker order between the two species for the eight macrochromosomes and the 14 microchromosomes studied. ConclusionIntegrating the two microsatellite and the AFLP quail genetic maps greatly enhances the quality of the resulting information and will thus facilitate the identification of Quantitative Trait Loci (QTL). The alignment with the chicken chromosomes confirms the high conservation of gene order that was expected between the two species for macrochromosomes. By extending the comparative study to the microchromosomes, we suggest that a wealth of information can be mined in chicken, to be used for genome analyses in quail.

Answer: Integrated maps in quail (Coturnix japonica) confirm the high degree of synteny conservation with chicken (Gallus gallus) despite 35 million years of divergence

Question: OBJECTIVE Mitochondrial disorders are caused by gene mutations in mitochondrial or nuclear DNA and affect energy-dependent organs such as the brain. Patients with psychiatric illness, particularly those with medical comorbidities, may have primary mitochondrial disorders. To date, this issue has received little attention in the literature, and mitochondrial disorders are likely underdiagnosed in psychiatric patients.
DATA SOURCES This article describes a patient who presented with borderline personality disorder and treatment-resistant depression and was ultimately diagnosed with mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) 3271. We also searched the literature for all case reports of patients with mitochondrial disorders who initially present with prominent psychiatric symptoms by using MEDLINE (from 1948-February 2011), Embase (from 1980-February 2011), PsycINFO (from 1806-February 2011), and the search terms mitochondrial disorder, mitochondria, psychiatry, mental disorders, major depression, anxiety, schizophrenia, and psychosis. STUDY SELECTION Fifty cases of mitochondrial disorders with prominent psychiatric symptomatology were identified.
DATA EXTRACTION Information about the psychiatric presentation of the cases was extracted. This information was combined with our case, the most common psychiatric manifestations of mitochondrial disorders were identified, and the important diagnostic and treatment implications for patients with psychiatric illness were reviewed.
RESULTS The most common psychiatric presentations in the cases of mitochondrial disorders included mood disorder, cognitive deterioration, psychosis, and anxiety. The most common diagnosis (52% of cases) was a MELAS mutation. Other genetic mitochondrial diagnoses included polymerase gamma mutations, Kearns-Sayre syndrome, mitochondrial DNA deletions, point mutations, twinkle mutations, and novel mutations.
CONCLUSIONS Patients with mitochondrial disorders can present with primary psychiatric symptomatology, including mood disorder, cognitive impairment, psychosis, and anxiety. Psychiatrists need to be aware of the clinical features that are indicative of a mitochondrial disorder, investigate patients with suggestive presentations, and be knowledgeable about the treatment implications of the diagnosis.

Answer:
The psychiatric manifestations of mitochondrial disorders: a case and review of the literature.
