Suppression of TGA2-Mediated Salicylic Acid Defence by Tomato Yellow Leaf Curl Virus C2 via Disruption of TCP7-Like Transcription Factor Activity in Tobacco.

Tomato yellow leaf curl virus (TYLCV) is a significant threat to tomato cultivation globally, transmitted exclusively by the whitefly Bemisia tabaci. While previous research suggests that the TYLCV C2 protein plays a role in fostering mutualistic interactions between the virus and its insect vectors, the specific mechanisms remain unclear. In this study, we show that the C2 protein interferes with the salicylic acid (SA) defence pathway by disrupting TCP7-like transcription factor-mediated regulation of TGA2 expression.

Strawberry anthocyanin pelargonidin-3-glucoside attenuated OA-induced neurotoxicity by activating UPR.

In this study, network pharmacology analysis revealed that strawberry anthocyanins mainly interfered with lipid metabolism and nerve-related signaling pathways. Pelargonidin-3-glucoside (Pg3G), one of the main anthocyanins in strawberry, was screened as the most effective anthocyanin for attenuating excess lipid accumulation. Moreover, Pg3G decreased lipid levels, relieved oxidative stress, and restored abnormal behavioral activities in under oleic acid (OA) exposure.

Intensive and Persistent Chemiluminescence from Orderly Arranged Ligands within Metal-Organic Frameworks for Inflammation Imaging.

Chemiluminescence offers ultrasensitive imaging for the diagnosis of a variety of diseases by removing the interference from excitation light sources. Here, we prepared two chemiluminescent metal-organic frameworks (Mn-ADA and Zn-ADA) by using (2,2')-3,3'-(anthracene-9,10-diyl)diacrylic acid (ADA) as a ligand. In Mn-ADA and Zn-ADA, the Mn atoms and Zn atoms are six-coordinated and eight-coordinated, respectively, and their frameworks are different in spatial structure.

Impacts of condensable particulate matter on atmospheric organic aerosols and fine particulate matter (PM) in China.

Condensable particulate matter (CPM) emitted from stationary combustion and mobile sources exhibits high emissions and a large proportion of organic components. However, CPM is not generally measured when conducting emission surveys of PM in most countries, including China. Consequently, previous emission inventories have not included emission rates for CPM.

Advances of research in diabetic cardiomyopathy: diagnosis and the emerging application of sequencing.

Diabetic cardiomyopathy (DCM) is one of the most prevalent and severe complications associated with diabetes mellitus (DM). The onset of DCM is insidious, with the symptoms being obvious only in the late stage. Consequently, the early diagnosis of DCM is a formidable challenge which significantly influences the treatment and prognosis of DCM.

The complex landscape of immune dysregulation in multisystem inflammatory syndrome in children with COVID-19.

The immune responses following SARS-CoV-2 infection in children are still under investigation. While coronavirus disease 2019 (COVID-19) is usually mild in the paediatric population, some children develop severe clinical manifestations or multisystem inflammatory syndrome in children (MIS-C) after infection. MIS-C, typically emerging 2-6 weeks after SARS-CoV-2 exposure, is characterized by a hyperinflammatory response affecting multiple organs.

Comparative dissection of transcriptional landscapes of human iPSC-NK differentiation and NK cell development.

Clinical and preclinical research has demonstrated that iPSC-derived NK (iNK) cells have a high therapeutic potential, yet poor understanding of the detailed process of their differentiation and their counterpart cell development has hindered therapeutic iNK cell production and engineering. Here we dissect the crucial differentiation of both fetal liver NK cells and iNK cells to enable the rational design of advanced iNK production protocols. We use a comparative analysis of single-cell RNA-seq (scRNA-seq) to pinpoint key factors lacking in the induced setting which we hypothesized would hinder iNK differentiation and/ or functionality.

Synergistic inhibition of colorectal cancer progression by silencing Aurora A and the targeting protein for Xklp2.

Background: Unraveling the pathogenesis of colorectal cancer (CRC) can aid in developing prevention and treatment strategies. Aurora kinase A (AURKA) is a key participant in mitotic control and interacts with its co-activator, the targeting protein for Xklp2 (TPX2) microtubule nucleation factor. AURKA is associated with poor clinical outcomes and high risks of CRC recurrence.

Evaluation of surgical strategy for low anterior resection syndrome using preoperative low anterior resection syndrome score in China.

Background: Despite improved survival rates in rectal cancer treatment, many patients experience low anterior resection syndrome (LARS). The preoperative LARS score (POLARS) aims to address the limitations of LARS assessment by predicting outcomes preoperatively to enhance surgical planning.

Aim: To investigate the predictive accuracy of POLARS in assessing the occurrence of LARS.

Monkey multi-organ cell atlas exposed to estrogen.

Awareness of estrogen's effects on health is broadening rapidly. The effects of long-term high levels of estrogen on the body involve multiple organs. Here, we used both single-cell chromatin accessibility and RNA sequencing data to analyze the potential effect of estrogen on major organs.

Apolipoprotein A-IV and its derived peptide, T55-121, improve glycemic control and increase energy expenditure.

It is crucial to understand the glucose control within our bodies. Bariatric/metabolic surgeries, including laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB), provide an avenue for exploring the potential key factors involved in maintaining glucose homeostasis since these surgeries have shown promising results in improving glycemic control among patients with severe type 2 diabetes (T2D). For the first time, a markedly altered population of serum proteins in patients after LSG was discovered and analyzed through proteomics.

Myokines: metabolic regulation in obesity and type 2 diabetes.

Skeletal muscle plays a vital role in the regulation of systemic metabolism, partly through its secretion of endocrine factors which are collectively known as myokines. Altered myokine levels are associated with metabolic diseases, such as type 2 diabetes (T2D). The significance of interorgan crosstalk, particularly through myokines, has emerged as a fundamental aspect of nutrient and energy homeostasis.

Neural innervation in adipose tissue, gut, pancreas, and liver.

Efficient communication between the brain and peripheral organs is indispensable for regulating physiological function and maintaining energy homeostasis. The peripheral nervous system (PNS) in vertebrates, consisting of the autonomic and somatic nervous systems, bridges the peripheral organs and the central nervous system (CNS). Metabolic signals are processed by both vagal sensory nerves and somatosensory nerves.

A deep learning framework for screening of anticancer drugs at the single-cell level.

Tumor heterogeneity plays a pivotal role in tumor progression and resistance to clinical treatment. Single-cell RNA sequencing (scRNA-seq) enables us to explore heterogeneity within a cell population and identify rare cell types, thereby improving our design of targeted therapeutic strategies. Here, we use a pan-cancer and pan-tissue single-cell transcriptional landscape to reveal heterogeneous expression patterns within malignant cells, precancerous cells, as well as cancer-associated stromal and endothelial cells.
