3%, 50/53) single nucleotide variations (SNVs) and three (5.7%, 3/53) long insertions/deletions. SNVs of MUC16 were the most common, and occurred in three cases (75%). Moreover, SNVs of EPHA8, FANCA, TRIO, and USP6 were detected in two out of four cases (50%). These 53 mutated genes were involved in 13 functional pathways based on enrichment analysis, especially in the PI3K-Akt signaling pathway. Finally, none of the cases showed obvious copy number variations, and had low tumor mutational burden and stable microsatellite sites.Long-term and mild confinement or isolation in an enclosed environment can occur in situations such as disasters, specific political, economic or social events, nuclear shelters, seabed exploration, polar expeditions, and space travel. To investigate the effects of stress caused by long-term confinement in an enclosed environment in mammals, we divided 8-week-old C57BL/6J mice into four groups that were housed in a closed environment with a narrow metabolic cage (stress group), normal metabolic cage (control group), conventional cage (conventional group) or conventional cage with wire mesh floor (wire mesh group). The phenotypes of the mice were examined for four weeks, followed by behavioral tests. Weight gain suppression was observed in the stress group. Continuous analysis of these mice every two minutes for four weeks using an implanted measuring device showed a significantly decreased amount of spontaneous activity and subcutaneous temperature in the stress group. After housing in each environment for four weeks, the behavioral tests of mice in the stress group also revealed a shorter latency to fall off in the rotarod test and shorter stride length and interstep distance in the footprint test. Interestingly, the lower spontaneous activity of mice in the stress group was rescued by housing in conventional cages. These results suggest a temporary effect of long-term confinement in an enclosed environment as a chronic and mild stress on homeostasis in mammals.Chronic ethanol exposure can increase the risk of depression. The α-amino-3‑hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptor is a key factor in depression and its treatment. The study was conducted to investigate the depressive-like behavior induced by chronic ethanol exposure in mice and to explore the mechanism in cells. To establish the chronic ethanol exposure mouse model, male C57BL/6 N mice were administered 10% (m/V) and 20% (m/V) ethanol as the only choice for drinking for 60 days, 90 days and 180 days. Depressive-like behavior in mice was confirmed by the forced swimming test (FST). Ethanol-induced changes in the mouse hippocampus were indicated by Western blotting, qPCR and Fluoro-Jade C (FJC) staining. We confirmed that 90- and 180-day ethanol exposure can lead to depressive-like mouse behavior, cell apoptosis, neuronal degeneration, a reduction in GluA1 and brain-derived neurotrophic factor (BDNF) expression, and an increase in IL-6 and IL-1β in the mouse hippocampus. GluA1 silencing and overexpression models of SH-SY5Y cells were established for further investigation. The cells were treated with 100 mM and 200 mM ethanol for 24 h. Ethanol exposure decreased cell viability and the expression of BDNF and increased the cell apoptosis rate and the expression of BAX, cleaved caspase-3, IL-1β and IL-6. GluA1 silencing aggravated ethanol-induced changes in cell viability and apoptosis and the expression of BDNF, BAX and cleaved caspase-3, and GluA1 overexpression attenuated these changes. Neither the silencing nor overexpression of GluA1 had an effect on ethanol-induced increases in IL-1β and IL-6. Our results indicated that chronic ethanol exposure induced depressive-like behavior in male C57BL/6 N mice by downregulating GluA1 expression.
The Dubin Johnson Syndrome (DJS) occurs mostly in young adults but an early-onset of the disease has been reported in less common forms (Neonatal DJS and Infantile DJS). In this case, the clinical findings are of limit for the DJS diagnosis. Hence, the genetic testing remains the method of choice to provide an accurate diagnosis. CB5083 In our study, we aimed to perform a genetic analysis for two siblings presented with an intrahepatic cholestasis before the age of 1year to provide a molecular explanation for the developed phenotype.
A Tunisian family, having two siblings, manifesting signs of a hepatopathy, was enrolled in our study. A molecular analysis was performed, using a panel-based next generation sequencing, supplying results that were the subject of computational analysis. Then, a clinical follow-up was carried out to assess the evolution of the disease.
The genetic analysis revealed the presence of a novel missense c.4179G>T, (p.M1393I) mutation in ABCC2 gene associated with a substitution c.2789G>A (R930Q) in ATP8B1 gene. Predictive results consolidated the pathogenic effect of both variants. These results confirmed the DJS diagnosis in the studied patients. The clinical course of both patients fit well with the benign nature of DJS.
We described here a novel ABCC2 mutation associated with a putative ATP8B1 modifier variant. This finding constituted the first report of a complex genotype in DJS. Hence, genetic analysis by a panel-based next generation sequencing permits an accurate diagnosis and the identification of putative variants that could influence the developed phenotype.

Where conventional blood sampling is challenging, dried blood spots (DBS) provide a practical sample alternative for measuring vitamin D levels. Our study aimed to develop and evaluate a clinical pathology service-based assay suitable for measuring vitamin D in batches of DBS samples collected remote to the testing site.
A high throughput liquid chromatography-tandem mass spectrometry (LC-MS/MS) method with derivatisation was developed to measure 25-hydroxyvitamin D metabolites (25OHD3, 25OHD2 and 3-epi-25OHD3) in DBS samples. The assay was validated using paired DBS and plasma samples from 37 healthy adults.
The assay reproducibly (<11.5% coefficient of variation) quantified 25OHD3 (range 1-300nmol/L), 25OHD2 (range 2-300nmol/L) and 3-epi-25OHD3 (range 1-200nmol/L) in DBS samples. The 25OHD3 metabolite was detected in all DBS samples, 3-epi-25OHD3 in six plasma (range 2.1-6.3nmol/L) and paired DBS samples, and 25OHD2 was not detected. Concentrations of 25OHD3 were highly correlated between paired samples capillary DBS and venous plasma (r=0.
