Further studies revealed that these neurochemical observations could be explained by increases in serotonin transporter (SERT) expression in the hippocampus driven by elevated neuroinflammation. Collectively, these results demonstrate that obesity-induced increases in neuroinflammation adversely affect SERT expression in the hippocampus of obese rats, thereby providing a potential synaptic mechanism for reduced SSRI responsiveness in obese subjects with co-morbid depressive illness.Cytomegalovirus (CMV) infection is usually inapparent in healthy adults but persists for life. Neural progenitor/stem cells are main CMV targets, and dentate gyrus (DG) a major neurogenic niche. Smaller DG volume has been repeatedly reported in severe mental illness (SMI). Considering the suggested immune system, blood-brain barrier and DG disturbances in SMI, we hypothesized that CMV exposure is associated with smaller DG volume in patients, but not healthy controls (HC). this website Due to the differential male and female immune response to CMV, we hypothesized sex-dependent associations. 381 adult patients with SMI (schizophrenia spectrum or bipolar spectrum disorders) and 396 HC were included. MRI scans were obtained with 1.5T Siemens MAGNETOM Sonata scanner or 3T General Electric Signa HDxt scanner, and processed with FreeSurfer v6.0. CMV immunoglobulin G antibody concentrations were measured by solid phase immunoassay. We investigated main and interaction effects of CMV status (antibody positivity/CMV + vs. negativity/CMV-) and sex on DG in patients and HC. Among patients, there was a significant CMV-by-sex interaction on DG (p = 0.009); CMV + male patients had significantly smaller DG volume than CMV- male patients (p = 0.001, 39 mm3 volume difference) whereas no CMV-DG association was found in female patients. Post-hoc analysis among male patients showed that the CMV-DG association was present in both hemispheres and in both patients with schizophrenia spectrum and bipolar spectrum disorders, and further, that higher CMV antibody titers were associated with smaller DG. No CMV-DG association was found in HC. The results indicate a DG vulnerability to CMV infection in men with SMI.Multidrug-resistant (MDR) Enterobacterales are a priority health issue with few treatment options. Recently, fosfomycin has been reconsidered for MDR bacterial infections. Zidovudine, licensed for the treatment of human immunodeficiency virus (HIV), has unexploited antibacterial properties and has been considered for drug repurposing. The aim of this study was to assess the effect of the combination of fosfomycin plus zidovudine against clinical MDR Enterobacterales isolates. Minimum inhibitory concentration (MIC) determination and checkerboard assays for 36 MDR Enterobacterales strains were performed. In addition, fosfomycin-resistant strains were evaluated using time-kill assay and in an in vivo Galleria mellonella infection model. Zidovudine and fosfomycin MICs ranged between 0.06 to >64 mg/L and 0.125 to >512 mg/L, respectively. A synergistic effect [fractional inhibitory concentration index (FICI) ≤0.5] was observed in 25 isolates and no antagonistic effect was observed in the remaining isolates. For 7 of 8 fosfomycin-resistant strains (MIC > 32 mg/L), zidovudine combination was able to restore fosfomycin susceptibility. These results were confirmed by time-kill assays. Fosfomycin + zidovudine presented greater larval survival (20-50%) than monotherapy. Synergistic activity was observed for fosfomycin + zidovudine in 69.4% of the tested strains. In vivo experiments confirmed the enhanced effectiveness of the combination. The zidovudine concentrations tested here can be reached in human serum using the actual licensed dosage, therefore this combination deserves further clinical investigation.Osteoporosis is a common disease in post-menopausal women. The increased risk of breast cancer and malignancy with hormone replacement, hampers its wide-usage. Phytoestrogens are known to have selective estrogen receptor modulator activity. The present study aims to determine how ferutinin affects unrestricted human Somatic Stem Cells (USSCs) osteogenic differentiation. The effect of ferutinin on USSCs proliferation was assessed by MTT assay while osteogenesis was evaluated using Alkaline Phosphatase Activity (ALP), calcium deposition and Alizarin Red Staining. Quantitative real-time PCR was applied to examine the expression of bone specific genes such as osteocalcin, Runx2, and BMP-2. Ferutinin (5-15 µg/mL) could positively impact on the proliferation of cells in a dose-dependent manner. Also, ALP enzyme activity and calcium deposition were enhanced in the presence of ferutinin. Based on real-time PCR results, ferutinin could increase the expression of bone marker genes. The pattern of ferutinin effect on gene expression is similar to standard synthetic estrogen, 17-β-estradiol. In the presence of the estrogen activity inhibitor (ICI), the effect of ferutinin on ALP and gene level was diminished. In conclusion, ferutinin may be considered as a potential candidate for the stem cell therapy in osteoporosis.Plant height is a fundamentally crucial agronomic trait to control crop growth and high yield cultivation. Several studies have been conducted on the understanding ofmolecular genetic bases of plant height in model plants and crops. However, the molecular mechanism underlying peanut plant height development is stilluncertain. In the present study, we created a peanut mutant library by fast neutron irradiation using peanut variety SH13 and identified a semi-dwarf mutant 1 (sdm1). At 84 DAP (days after planting), the main stem of sdm1 was only about 62% of SH13. The internode length of sdm1 hydroponic seedlings was found significantly shorter than that of SH13 at 14 DAP. In addition, the foliar spraying of exogenous IAA could partially restore the semi-dwarf phenotype of sdm1. Transcriptome data indicated that the differentially expressed genes (DEGs) between sdm1 and SH13 significantly enriched in diterpenoid biosynthesis, alpha-linolenic acid metabolism, brassinosteroid biosynthesis, tryptophan metabolism and plant hormone signal transduction. The expression trend of most of the genes involved in IAA and JA pathway showed significantly down- and up- regulation, which may be one of the key factors of the sdm1 semi-dwarf phenotype. Moreover, several transcription factorsand cell wall relatedgenes were expressed differentially between sdm1 and SH13. Conclusively, this research work not only provided important clues to unveil the molecular mechanism of peanut plant height regulation, but also presented basic materials for breeding peanut cultivars with ideal plant height.Cluster bean (Guar) is the major source of industrial gum. Knowledge on the molecular events regulating galactomannan gum accumulation in guar will pave way for accelerated development of gummy guar genotypes. RNA Seq analysis in the immature seeds of contrasting cluster bean genotypes HGS 563 (gum type) and Pusa Navbahar (vegetable type) resulted in the generation of 19,855,490 and 21,488,472 quality reads. Data analysis identified 4938 differentially expressed genes between the gummy vs vegetable genotypes. A set of 2241 genes were up-regulated and 2587 genes were down-regulated in gummy guar. Significant up-regulation of genes involved in the biosynthesis of galactomannan and cell wall storage polysaccharides was observed in the gummy HGS 563. Genes involved in carotenoids, flavonoids, non mevalonic acid, terpenoids, and wax metabolism were also up-regulated in HGS 563. Mannose and galactose were the major nucleotide sugars in Pusa Navbahar and HGS 563 immature seeds. Immature seeds of HGS 563 showed high concentration of mannose and galactose accumulation compared to Pusa Navbahar. qRT-PCR analysis of selected genes confirmed the findings of transcriptome data.The 14-3-3 family genes are highly conserved regulatory factors in eukaryotes with involvement in multiple important cellular processes. However, detailed investigations of this family in fishes are very limited. Here, a comparative genomic and transcriptomic survey were performed to investigate the 14-3-3 family in fishes. We confirmed that the numbers of 14-3-3 genes ranged from 5 to 7 in non-teleost fishes, as well as additional 14-3-3 genes (9 to 11) in teleost fishes. In addition, some special teleost fishes possess 17 to 25 14-3-3s, which undergone the fourth whole-genome duplication (WGD). We also found that six pairs of fish 14-3-3 genes were clustered with mammalian ε, γ, ς, η, τand β isotypes, respectively, while σ was absent with a potential specificity within mammals, on the basis of their phylogenetic and synteny analyses. According to our results, we inferred that the diversity of 14-3-3 genes in fishes seems to be generated from a combination of WGD and gene loss. Comparative transcriptomic analysis revealed that there are differences in tissue distribution, and we speculated that 14-3-3 genes may contribute to terrestrial adaptations in mudskippers. In addition, protein sequence alignments of 14-3-3s supported their differential roles in fishes. In summary, our present comparative genomic and transcriptomic survey will benefit for further functional investigations of these fish genes.Ankyrin repeat domain 1 (ANKRD1) is a functionally pleiotropic protein found in the nuclei and sarcomeres of cardiac and skeletal muscles, with a proposed role in linking myofibrilar stress and transcriptional regulation. Rapid upregulation of its expression in response to both physiological and pathological stress supports the involvement of ANKRD1 in muscle tissue adaptation and remodeling. However, the exact role of ANKRD1 remains poorly understood. To begin to investigate its function at higher resolution, we have generated and characterized a TgBAC(ankrd1aEGFP) zebrafish line. This reporter line displays transgene expression in slow skeletal muscle fibers during development and exercise responsiveness in adult cardiac muscle. To better understand the role of Ankrd1a in pathological conditions in adult zebrafish, we assessed ankrd1a expression after cardiac ventricle cryoinjury and observed localized upregulation in cardiomyocytes in the border zone. We show that this expression in injured hearts is recapitulated by the TgBAC(ankrd1aEGFP) reporter. Our results identify novel expression domains of ankrd1a and suggest an important role for Ankrd1a in the early stress response and regeneration of cardiac tissue. This new reporter line will help decipher the role of Ankrd1a in striated muscle stress response, including after cardiac injury.Traditional herbal medicine (THM) comprises a vast number of natural compounds. Most of them are metabolized into different structures after administration, which makes the clarification of THM's mode of action more complicated. To evaluate the biological activities of those components and metabolites, in silico simulation technology is helpful. We focused on mixed-solvent molecular dynamics (MD) simulation for druggability assessment of natural products. Mixed-solvent MD is an in silico simulation method for the exploration of ligand-binding sites on target proteins, which uses water and an organic molecule mixture. The selection of organic small molecules is an important factor for predicting the characteristics of natural products. In this study, we used the known crystal structure of estrogen receptors with genistein as a test case and explored fragments reflecting the characteristics of natural products. We found that structures with a 4-pyrone structure are more often included in the natural products database compared with the DrugBank database, and we selectively detected the known-binding sites of estrogen receptor α and β.
