Grapevine red blotch-associated virus (GRBaV) is a major threat to the wine industry in the USA. GRBaV infections (aka red blotch disease) compromise crop yield and berry chemical composition, affecting the flavor and aroma properties of must and wine. In this study, we combined genome-wide transcriptional profiling with targeted metabolite analyses and biochemical assays to characterize the impact of the disease on red-skinned berry ripening and metabolism. Using naturally infected berries collected from two vineyards, we were able to identify consistent berry responses to GRBaV across different environmental and cultural conditions...

Sensing of extracellular calcium(Ca2+)levels involves the Ca-sensing receptor(CaSR), its downstream signaling molecule Gα11, and the adaptor-related protein complex 2(AP2)that plays a role in clathrin-dependent endocytosis of CaSR. Inactivating mutations in CaSR cause familial hypocalciuric hypercalcemia type 1(FHH1)and neonatal severe hyperparathyroidism(NSHPT), while activating mutations lead to autosomal dominant hypocalcemia type 1(ADH1)and Bartter syndrome type Ⅴ. Recent studies have identified that inactivating mutations in Gα11 and σ-subunit of AP2(AP2σ)also cause FHH, and these conditions have been classified as FHH2 and FHH3, respectively...

Seed development in dicots undergoes an early endosperm proliferation, followed by the growth of embryo to replace the endosperm. Endosperm proliferation in dicots not only provides nutrient supplies for subsequent embryo development but also enforces a space limitation to influence the final seed size. Overexpression of Arabidopsis SHORT HYPOCOTYL UNDER BLUE1::GUS (SHB1:GUS) in canola produced large seeds. We performed global analysis of canola genes that were expressed and influenced by SHB1 during early endosperm proliferation at 8 days after pollination (DAP) and late embryo development at 13 DAP...

BACKGROUND: Adipocyte fatty acid-binding protein, also known as aP2 or fatty acid-binding protein 4 (FABP4), plays an important role in inflammatory and metabolic responses in adipocytes and macrophages. Recent work has demonstrated that macrophage FABP4 integrates inflammatory and lipid metabolic responses, thereby contributing to the development of insulin resistance and atherosclerosis. However, it is not known whether FABP4 in human pulmonary artery endothelial cells(HPAECs) modulates inflammation...

Phytophthora root and stem rot of soybean caused by the oomycete Phytophthora sojae, is a destructive disease worldwide. Ethylene response factors (ERFs) play important roles in regulating plant biotic and abiotic stress tolerance. In this study, a new ERF gene, GmERF113, was isolated from the highly resistant soybean 'Suinong 10.' Sequence analysis suggested that the protein encoded by GmERF113 contained a conserved AP2/ERF domain of 58 amino acid and belonged to the B-4 subgroup of the ERF subfamily. Expression of GmERF113 was significantly induced by P...

Transcription factors of the AP2/ERF family play important roles in plant growth, development, and responses to biotic and abiotic stresses. In this study, a physic nut AP2/ERF gene, JcDREB2, was functionally characterized. Real-time PCR analysis revealed that JcDREB2 was expressed mainly in the leaf and could be induced by abscisic acid but suppressed by gibberellin (GA) and salt. Transient expression of a JcDREB2-YFP fusion protein in Arabidopsis protoplasts cells suggested that JcDREB2 is localized in the nucleus...

WRINKLED1 (WRI1), a member of the APETALA2 (AP2) class of transcription factors, positively regulates glycolysis and lipid biosynthesis in Arabidopsis thaliana. Here we identify mechanistic links between KIN10, the major SUCROSE NON-FERMENTATION-1 (SNF1)-RELATED KINASE 1 (SnRK1) involved in sugar/energy homeostasis and the posttranslational regulation of WRI1. Transient expression of WRI1 with OLEOSIN1 (OLE1) in Nicotiana benthamiana stimulates triacylglycerol (TAG) accumulation, but their coexpression with KIN10 abrogates this effect by inducing proteasomal degradation of WRI1...

BACKGROUND: To understand the changes of gene regulation in carcinogenesis, we explored signals of DNA methylation - a stable epigenetic mark of gene regulatory elements - and designed a computational model to profile loss and gain of regulatory elements (REs) during carcinogenesis. We also utilized sequencing data to analyze the allele frequency of single nucleotide polymorphisms (SNPs) and detected the cancer-associated SNPs, i.e., the SNPs displaying the significant allele frequency difference between cancer and normal samples...

Invariant natural killer T (iNKT) cells are innate T cells with powerful immune regulatory functions that recognize glycolipid antigens presented by the CD1D protein. While iNKT-cell-activating glycolipids are currently being explored for their efficacy to improve immunotherapy against infectious diseases and cancer, little is known about the mechanisms that control CD1D antigen presentation and iNKT cell activation in vivo. CD1D molecules survey endocytic pathways to bind lipid antigens in MHC class II containing compartments (MIICs) before recycling to the plasma membrane...

The Rab protein family is the largest family of the small GTP-binding proteins. Among them, the RabG genes are known to be responsive to abiotic stresses, but the molecular mechanisms of the stress responses mediated by RabG genes in plants is poorly understood. To investigate the molecular mechanism of AhRabG gene in peanut, transgenic plants overexpressing the AhRabG gene (S6) with relatively higher salinity resistance than the non-transgenic plants (S7) were obtained. Digital gene expression (DGE) sequencing was performed with the leaves of S6 and S7 plants before and after salinity-stress treatment...

Sepsis is defined as the host's deleterious systemic inflammatory response to microbial infections. Herein, we report an essential role of the fatty acid binding protein 4 (FABP4; alias adipocyte protein 2 or aP2), a lipid-binding chaperone, in sepsis response. Bioinformatic analysis of the Gene Expression Omnibus data sets showed the level of FABP4 was higher in the nonsurvival sepsis patients' whole blood compared to the survival cohorts. The expression of Fabp4 was induced in a liver-specific manner in cecal ligation and puncture (CLP) and lipopolysaccharide treatment models of sepsis...

The highly conserved eukaryotic WD40 repeat protein, Receptor for Activated C Kinase 1 (RACK1), is involved in the abscisic acid (ABA) response in Arabidopsis. However, the regulation of RACK1 and the proteins with which it interacts are poorly understood. Here, we show that RACK1B is sumoylated at four residues, Lys50, Lys276, Lys281 and Lys291. Sumoylation increases RACK1B stability and its tolerance to ubiquitination-mediated degradation in ABA response. As a result, sumoylation leads to enhanced interaction between RACK1B and RAP2...

Multiple environmental stresses affect growth and development of plants. Plants try to adapt under these unfavorable condition through various evolutionary mechanisms like physiological and biochemical alterations connecting various network of regulatory processes. Transcription factors (TFs) like APETALA2/ETHYLENE RESPONSE FACTORS (AP2/ERFs) are an integral component of these signaling cascades because they regulate expression of a wide variety of down stream target genes related to stress response and development through different mechanism...
