RBP2

BACKGROUND: Acute Respiratory Distress Syndrome (ARDS) is a common condition in the intensive care unit (ICU) with a high mortality rate, yet the diagnosis rate remains low. Recent studies have increasingly highlighted the role of aging in the occurrence and progression of ARDS. This study is committed to investigating the pathogenic mechanisms of cellular and genetic changes in elderly ARDS patients, providing theoretical support for the precise treatment of ARDS. METHODS: Gene expression profiles for control and ARDS samples were obtained from the Gene Expression Omnibus (GEO) database, while aging-related genes (ARGs) were sourced from the Human Aging Genomic Resources (HAGR) database...

A lysine-specific demethylase is an enzyme that selectively eliminates methyl groups from lysine residues. KDM5A, also known as JARID1A or RBP2, belongs to the KDM5 Jumonji histone demethylase subfamily. To identify novel molecules that interact with the LSD5A receptor, we created a quantitative structure-activity relationship (QSAR) model. A group of 435 compounds was used in a study of the quantitative relationship between structure and activity to guess the IC50 values for blocking LASD5A. We used a genetic algorithm-multilinear regression-based quantitative structure-activity connection model to forecast the bioactivity (P IC50 ) of 1615 food and drug administration pharmaceuticals from the zinc database with the goal of repurposing clinically used medications...

As an important edible mushroom, morel mushroom (Morchella spp.) has been widely spread and cultivated in China. However, between 2022 and 2023, a rot disease with a natural incidence of 28% occurred in morel mushroom farms in the Qingpu district of Shanghai (N30°97', E121°06'), China. High temperatures (>20℃) and high humidity (>70%) provide conditions conducive to the spread of this disease. First, a small white mold-like symptoms appeared on the surface or the pinnacle of pileus. The tissues in the infected parts stop growing and developing...

Chile leads cherry exports in the southern hemisphere with a total of 415.315 t exported in the 2022 to 2023 season (IQonsulting, 2023). Cytospora canker, produced by Cytospora spp., causes destructive infections and limit the productivity of sweet cherry orchards (Luo et al. 2019). This study was focused on isolating Cytospora strains to identify and characterize the species present in sweet cherry. During the period 2019-2022, ten samples of stem or branch presenting canker, dieback, gummosis or dead buds, were collected from sweet cherry cultivars 'Skeena', 'Lapins', 'Santina', 'Sweetheart', and 'Regina', in the regions Ñuble and O'Higgins, Chile...

Biobased and biodegradable polymeric materials are a sustainable alternative to the conventional plastics used in food packaging. This study investigated the possible effect of biobased cling films derived from renewable and circular and sustainable sources on key cheese sensory parameters (appearance and odor) able to influence consumer acceptance or rejection of a food product over time. For this purpose, a semi-hard cheese was selected as food model and stored for 14 days at 5 °C wrapped with five cling films: two bio-plastic materials from renewable circular and sustainable sources (R-BP1 and R-BP2), one bio-plastic film from a non-renewable source (NR-BP), and two conventional cling films (LDPE and PVC)...

BACKGROUND: Retinol-binding protein 2 (RBP2) is an intracellular carrier for vitamin A in the absorptive enterocytes. Mice lacking RBP2 (Rbp2-/- ) display an unexpected phenotype of obesity, glucose intolerance, and elevated glucose-dependent insulinotropic polypeptide (GIP) levels. GIP and glucagon-like peptide 1 (GLP-1) are incretin hormones secreted by enteroendocrine cells (EECs). We recently demonstrated the presence of RBP2 and other retinoid-related proteins in EECs. OBJECTIVES: Given RBP2's role in intracellular retinoid trafficking, we aimed to evaluate whether dietary vitamin A affects incretin-secreting cell function and gene expression...

The cyanobacterial circadian oscillator, consisting of KaiA, KaiB, and KaiC proteins, drives global rhythms of gene expression and compaction of the chromosome and regulates the timing of cell division and natural transformation. While the KaiABC posttranslational oscillator can be reconstituted in vitro, the Kai-based oscillator is subject to several layers of regulation in vivo. Specifically, the oscillator proteins undergo changes in their subcellular localization patterns, where KaiA and KaiC are diffuse throughout the cell during the day and localized as a focus at or near the pole of the cell at night...

In this study, a fungal strain KNUF-22-025 belonging to the genus Botryotrichum was isolated from the soil in Korea. The cultural and morphological characteristics of this strain differed from those of closely related species. On malt extract agar, strain KNUF-22-025 showed slower growth than most of the related species, except B. domesticum . The conidia size (9.6-21.1 × 9.9-18.4 µm) of strain KNUF-22-025 was larger than those of B. piluliferum , B. domesticum , and B. peruvianum but smaller than those of B...

Several elements have an impact on COVID-19, including comorbidities, age and sex. To determine the protein profile changes in peripheral blood caused by a SARS-CoV-2 infection, a proximity extension assay was used to quantify 1387 proteins in plasma samples among 28 Finnish patients with COVID-19 with and without comorbidities and their controls. Key immune signatures, including CD4 and CD28, were changed in patients with comorbidities. Importantly, several unreported elevated proteins in patients with COVID-19, such as RBP2 and BST2, which show anti-microbial activity, along with proteins involved in extracellular matrix remodeling, including MATN2 and COL6A3, were identified...

Tobacco (Nicotiana tabacum L.) is an important economic crop belonging to family Solanaceae and is widely cultivated in China (Basit 2021). From April to July in 2022, a foliar disease with symptoms similar to grey spot was extensively observed on tobacco in Guangxi Province (24°52' N, 111°23' E), China. Field surveys were conducted in 18 towns and the disease incidence was 0.89% to 6.95%. Symptomatic leaves displayed irregular, dark brown lesions surrounded by yellow halos and accompanied with black conidiomata in gray centers (Fig 1A-E)...

To explore whether a probiotic complex composed of Lactobacillus rhamnosus , Lactobacillus plantarum , and Lactobacillus casei can prevent or inhibit the inflammatory response caused by the invasion of Plesiomonas shigelloides in the southern catfish, we screened differentially expressed genes and enriched inflammation-related pathways among a control and three experimental groups and conducted analysis by transcriptome sequencing after a 21-day breeding experiment. Compared with those in the PS ( Plesiomonas shigelloides ) group, southern catfish in the L-PS ( Lactobacillus-Plesiomonas shigelloides ) group had no obvious haemorrhages or ulcerations...

In November 2018, symptoms of brown rot were observed on chayote ( Sechium edule ) var. nigrum spinosum with a 20% disease incidence of 120 harvested fruits in the National Germplasm Bank of Sechium edule , located in the Centro Regional Universitario Oriente (CRUO) from the Chapingo Autonomous University (Huatusco, Veracruz, Mexico). For fungal isolation, pieces from symptomatic fruits were surface disinfected by immersion in a 1.5% NaClO solution for 2 min, rinsed in sterile distilled water, placed in Petri plates containing potato dextrose agar (PDA) amended with kanamycin sulfate, and incubated at 25ºC...

Background: Crohn's Disease (CD) is an inflammatory disease of the gastrointestinal tract that affects millions of patients. While great strides have been made in treatment, namely in biologic therapy such as anti-TNF drugs, CD remains a significant health burden. Method: We conducted two meta-analyses using our STARGEO platform to tag samples from Gene Expression Omnibus. One analysis compares inactive colonic biopsies from CD patients to colonic biopsies from healthy patients as a control and the other compares colonic biopsies from active CD lesions to inactive lesions...

Common bean ( Phaseolus vulgaris L.), is a grain legume widely cultivated worldwide for its edible dry seeds and pods. In February 2021, root rot symptoms were observed in two common bean (cv. Azufrado Higuera) fields located in Ahome (25º96´19¨N, 109º33´42¨W) and Guasave (25º71´85¨N, 108º78´50¨W) municipalities in Sinaloa, Mexico. Diseased plants showed reduced growth, dark brown canker at the base of the stem, root rot, as well as the absence of secondary roots. The disease incidence was estimated up to 35%...

Background: Immune-related genes (IRGs) are closely connected to the occurrence and development of tumors. Their influence on the prognosis of patients with HCC, however, remains unclear. Methods: From the TCGA database, we integrated 365 liver cancer tissues and 50 normal tissues to identify differential immune genes related to prognosis. Multivariate COX analysis was used to establish a new prognostic index on account of IRGs, whereby risk score = (Expression level of HSPA4*0...

Retinol-binding protein 2-deficient (Rbp2-/-) mice are more prone to obesity, glucose intolerance, and hepatic steatosis than matched controls. Glucose-dependent insulinotropic polypeptide (GIP) blood levels are dysregulated in these mice. The present studies provide new insights into these observations. Single cell transcriptomic and immunohistochemical studies establish that RBP2 is highly expressed in enteroendocrine cells (EECs) that produce incretins, either GIP or glucagon-like peptide-1 (GLP-1). EECs also express an enzyme needed for all-trans-retinoic acid (ATRA) synthesis, ALDH1A1, and retinoic acid receptor-α (RARα), which mediates ATRA-dependent transcription...

Retinol-binding protein 2 (RBP2, also known as cellular retinol-binding protein 2 (CRBP2)) is a member of the fatty acid-binding protein family and has been extensively studied for its role in facilitating dietary vitamin A (retinol) uptake and metabolism within enterocytes of the small intestine. RBP2 is present in highest concentrations in the proximal small intestine where it constitutes approximately 0.1-0.5% of soluble protein. Recent reports have established that RBP2 binds monoacylglycerols (MAGs) with high affinity, including the canonical endocannabinoid 2-arachidonoylglycerol (2-AG)...

Pinus thunbergii Parl. (Japanese black pine), an evergreen species, is distributed along the seacoasts of China. In addition, this species has been planted along seacoasts as a windbreak to prevent soil erosion due to its resistance to salt and various environmental stresses. It can also be found in public parks and gardens due to its exquisite appearance and toughness. In August 2020, needle blight symptoms were found on several black pine trees in Sichuan Province, China. Further surveys showed that these symptoms are common...

Plant mitoviruses belong to Mitoviridae family and consist of positive single-stranded RNA genomes replicating exclusively in host mitochondria. We previously reported the biological characterization of a replicating plant mitovirus, designated Chenopodium quinoa mitovirus 1 (CqMV1), in some Chenopodium quinoa accessions. In this study, we analyzed the mitochondrial proteome from leaves of quinoa, infected and not infected by CqMV1. Furthermore, by protein-protein interaction and co-expression network models, we provided a system perspective of how CqMV1 affects mitochondrial functionality...
