Transcription factor CaPHR3 enhances phosphate starvation tolerance by up-regulating the expression of the CaPHT1;4 phosphate transporter gene in pepper.

Plants frequently encounter phosphate (Pi) starvation due to its scarce availability in soil, necessitating an adaptive phosphate starvation response (PSR). This study explores this adaptation in pepper (Capsicum annuum L.) under low-Pi stress, focusing on the PHOSPHATE STARVATION RESPONSE (PHR) gene family.

SHIP-1 regulates the differentiation and function of Tregs via inhibiting mTORC1 activity.

Cell metabolism is crucial for orchestrating the differentiation and function of regulatory T cells (Tregs). However, the underlying mechanism that coordinates cell metabolism to regulate Treg activity is not completely understood. As a pivotal molecule in lipid metabolism, the role of SHIP-1 in Tregs remains unknown.

High-Quality SnSe Thin Films for Self-Powered Devices and Multilevel Information Encryption.

As semiconductor technology advances toward miniaturization and portability, thin films with excellent thermoelectric performance have garnered increasing attention, particularly for applications in self-powered devices and temperature-responsive sensors. The high Seebeck coefficient of SnSe thin films makes them promising for temperature sensing, but their poor electrical conductivity limits their potential as thermoelectric generators. In this work, high-quality -axis oriented SnSe thin films were deposited on quartz substrates by using magnetron sputtering.

A prior-knowledge-guided dynamic attention mechanism to predict nocturnal hypoglycemic events in type 1 diabetes.

Ubiquitin-Proteasome System in Periodontitis: Mechanisms and Clinical Implications.

The progression of periodontitis, a bacteria-driven inflammatory and bone-destructive disease, involves myriad cellular and molecular mechanisms. Protein regulation significantly influences the pathogenesis and management of periodontitis. However, research regarding its regulatory role in periodontitis remains relatively limited.

4H-SiC Metalens: Mitigating Thermal Drift Effect in High-Power Laser Irradiation.

Enhancing energy density and efficiency in laser processing hinges on precise beam focusing, yet this often causes severe heat absorption and focus shifts in optical lenses. Traditional cooling methods increase cost and complexity, severely limiting versatility. Here, monolithic silicon carbide (SiC) metalens is introduced, which shows unparalleled thermal stability, integrated with a high-power laser.

ARID1A is a coactivator of STAT5 that contributes to CD8 T cell dysfunction and anti-PD-1 resistance in gastric cancer.

ARID1A deletion mutation contributes to improved treatment of several malignancies with immune checkpoint inhibitors (ICIs). However, its role in modulating of tumor immune microenvironment (TIME) of gastric cancer (GC) remains unclear. Here, we report an increase of CD8 T cells infiltration in GC patients with ARID1A-mutation (MUT), which enhances sensitivity to ICIs.

Endoscopic far-lateral supracerebellar infratentorial approach for resection of clival chordoma: case report.

Introduction: The surgery of clival chordoma remains one of the most formidable challenges for neurosurgeons because of its location at great depth in the cranium and proximity to critical neurovascular structures. Here, we describe the technique and feasibility of the purely endoscopic far-lateral supracerebellar infratentorial approach (EF-SCITA) for resection of an intradural clival chordoma.

Case Description: A 68-year-old women presented with sudden ptosis on the left side for two weeks.

Integrated analysis of transcriptome and proteome reveals a core set of genes involved in osteoblast under oxidative stress.

Osteoblasts dysfunction, induced by oxidative stress (OS), is a significant contributor to the pathogenesis of osteoporosis. However, the genes implicated in regulating osteoblast dysfunction remain unclear. Here, we employed the hydrogen peroxide (HO)-induced osteoblast dysfunction model to assess its impact on osteoblast phenotype and to conduct transcriptome and proteome analyses in osteoblasts under OS.

Role of the PGAM5-CypD mitochondrial pathway in methylglyoxal-induced bone loss in diabetic osteoporosis.

Diabetic osteoporosis (DOP) is a skeletal complication with a high rate of disability. It results in a great burden to the patient's family and society. Methylglyoxal (MG) is a toxic by-product of the glycolytic process that occurs during diabetic conditions.

Afadin mediates cadherin-catenin complex clustering on F-actin linked to cooperative binding and filament curvature.

The E-cadherin-β-catenin-αE-catenin (cadherin-catenin) complex couples the cytoskeletons of neighboring cells at adherens junctions (AJs) to mediate force transmission across epithelia. Mechanical force and auxiliary binding partners converge to stabilize the cadherin-catenin complex's inherently weak binding to actin filaments (F-actin) through unclear mechanisms. Here we show that afadin's coiled-coil (CC) domain and vinculin synergistically enhance the cadherin-catenin complex's F-actin engagement.

PD-L1 neutrophils induced NETs in malignant ascites is a potential biomarker in HCC.

Background: Since differentiating malignant ascites from benign ascites has always been a clinical difficult, recognition of novel biomarkers in malignant ascites of hepatocellular carcinoma (HCC) patients could be helpful for establishing a diagnosis for HCC patients with ascitic fluids.

Methods: Thirty-five HCC patients with malignant ascites and chronic liver diseases patients with benign ascites were enrolled. Serum and ascites specimens were collected to determine TAN subpopulations and NETs concentration.

/GRSF1/COX1 axis attenuates early brain injury via maintaining mitochondrial function after subarachnoid haemorrhage.

Background: Guanine-rich RNA sequence binding factor 1 (GRSF1) is an RNA-binding protein, which is eventually localised to mitochondria and promotes the translation of cytochrome C oxidase 1 (COX1) mRNA. However, the role of the p/GRSF1/COX1 axis has not been investigated in an experimental subarachnoid haemorrhage (SAH) model. Thus, we investigated the role of the p/GRSF1/COX1 axis in a SAH-induced early brain injury (EBI) course.

The kynurenine pathway regulated by intestinal innate lymphoid cells mediates postoperative cognitive dysfunction.

Postoperative cognitive dysfunction (POCD) is a prevalent neurological complication that can impair learning and memory for days, months, or even years after anesthesia/surgery. POCD is strongly associated with an altered composition of the gut microbiota (dysbiosis), but the accompanying metabolic changes and their role in gut-brain communication and POCD pathogenesis remain unclear. Here, the present study reports that anesthesia/surgery in aged mice induces elevated intestinal indoleamine 2,3-dioxygenase (IDO) expression and activity, which shifts intestinal tryptophan (TRP) metabolism toward more IDO-catalyzed kynurenine (KYN) and less gut bacteria-catabolized indoleacetic acid (IAA).

Causal relationships of infection with and herpesvirus on periodontitis: A Mendelian randomization study.

Background: To explore the causal association between () infection, herpesvirus infection and periodontitis (PD) from a genetic perspective using Mendelian randomization (MR).

Methods: The PD data were derived from genome-wide association study (GWAS) from the Dental Endpoints (GLIDE) consortium, and the FinnGen Biobank provided data on and herpesvirus infections. In addition, we examined GWAS data for subtypes of and herpesvirus infection.

Myosin forces elicit an F-actin structural landscape that mediates mechanosensitive protein recognition.

Cells mechanically interface with their surroundings through cytoskeleton-linked adhesions, allowing them to sense physical cues that instruct development and drive diseases such as cancer. Contractile forces generated by myosin motor proteins mediate these mechanical signal transduction processes through unclear protein structural mechanisms. Here, we show that myosin forces elicit structural changes in actin filaments (F-actin) that modulate binding by the mechanosensitive adhesion protein α-catenin.
