Identification the Cellular Senescence Associated lncRNA LINC01579 in Gastric Cancer.

Cellular senescence is a key promoter of tumorigenesis and malignant progression. This study aimed to develop a predictive model for assessing cellular senescence in gastric cancer (GC) outcomes. We identified senescence-related genes and lncRNAs from 375 stomach adenocarcinoma (STAD) patients and established a prognostic senescence score using multivariate Cox regression, validated in testing, TCGA-STAD and the combined TCGA-COAD and READ cohorts.

[Mining, characterization, and expression of a fructan sucrase for efficient conversion of soybean oligosaccharides].

The high content of sucrose and raffinose reduces the prebiotic value of soybean oligosaccharides. Fructan sucrases can catalyze the conversion of sucrose and raffinose to high-value products such as fructooligosaccharides and melibiose. To obtain a fructan sucrase that can efficiently convert soybean oligosaccharides, we first mined the fructan sucrase gene from microorganisms in the coastal areas of Xisha Islands and Bohai Bay and then characterized the enzymatic and catalytic properties of the enzyme.

Comprehensive analysis of the transcriptome-wide m6A Methylome in sheep testicular development.

N6-methyladenosine (m6A) modification of RNA is a critical post-transcriptional modification, that dynamically contributes to testicular development and spermatogenesis. Nevertheless, the investigation into the role of m6A in testicular development of sheep remains insufficient. Herein, we conducted a comprehensive analysis of the m6A transcriptome landscape in the testes of F1 hybrid Southdown × Hu sheep across M0 (0 months old, newborn), M3 (3 months old, sexually immature), M6 (6 months old, sexually mature), and Y1 (1 years old, adult).

Protease activity of NIa-Pro determines systemic pathogenicity of clover yellow vein virus.

Clover yellow vein virus (ClYVV), a potyvirus that infects various dicotyledonous plants, poses a significant threat to the cultivation of legumes.

Selenium-Chondroitin Sulfate Nanoparticles Inhibit Angiogenesis by Regulating the VEGFR2-Mediated PI3K/Akt Pathway.

Chondroitin sulfate (CS), a class of glycosaminoglycans covalently attached to proteins to form proteoglycans, is widely distributed in the extracellular matrix and cell surface of animal tissues. In our previous study, CS was used as a template for the synthesis of seleno-chondroitin sulfate (SeCS) through the redox reaction of ascorbic acid (Vc) and sodium selenite (NaSeO) and we found that SeCS could inhibit tumor cell proliferation and invasion. However, its effect on angiogenesis and its underlying mechanism are unknown.

Comparing International Guidelines for the Remission of Hypertension After Bariatric Surgery.

Background/objectives: Obesity remains a global health concern and is associated with increased risk of type 2 diabetes, hypertension, and cardiovascular disease overall. Dissimilar hypertension guidelines are available for clinicians, namely those prepared by the American Heart Association (AHA) and the European Society of Cardiology (ESC), which may lead to distinctive appreciation of health outcomes of patients with obesity after bariatric and metabolic surgery, such as hypertension remission. The main goal of this study was to compare the effects of applying stricter (AHA) versus looser (ESC) blood pressure criteria on hypertension diagnosis pre-bariatric surgery and remission assessment one year post-op.

Blockade of TIPE2-Mediated Ferroptosis of Myeloid-Derived Suppressor Cells Achieves the Full Potential of Combinatory Ferroptosis and Anti-PD-L1 Cancer Immunotherapy.

Although immune checkpoint blockade (ICB) therapy has attained unprecedented clinical success, the tolerance and immune suppression mechanisms evolved by tumor cells and their tumor microenvironment (TME) hinder its maximum anti-cancer potential. Ferroptosis therapy can partially improve the efficacy of ICB, but it is still subject to immune suppression by myeloid-derived suppressor cells (MDSCs) in the TME. Recent research suggests that an MDSC blockade can unleash the full therapeutic potential of the combined therapy of ferroptosis and ICB in liver cancer treatment.
