ABCA1-Super Enhancer RNA Promotes Cholesterol Efflux, Reduces Macrophage-Mediated Inflammation and Atherosclerosis.

We describe a previously uncharacterized ATP-binding cassette A1 super enhancer RNA (ABCA1-seRNA)-mediated cholesterol efflux. In addition, it promoted macrophage inflammatory cytokine release, and was causally correlated with coronary artery disease severity. Mechanistically, ABCA1-seRNA upregulated cholesterol efflux by interacting with mediator complex subunit 23 and recruiting retinoid X receptor-alpha and liver X receptor-alpha to promote ABCA1 transcription in a manner.

Immune Microenvironment in Breast Cancer Metastasis.

Metastatic disease is the final stage of breast cancer that accounts for vast majority of patient death. Mounting data over recent years strongly support the critical roles of the immune microenvironment in determining breast cancer metastasis. The latest single-cell studies provide further molecular evidence illustrating the heterogeneity of this immune microenvironment.

Structure Characterization and Antioxidant Properties of a Triple Helix Galactoglucomannan from the Fruiting Bodies of Russula virescens (Agaricomycetes).

RVP, a water-soluble triple-helix galactoglucomannan, was successfully extracted from the fruiting body of Russula virescens using an alkali extraction method. Physicochemical properties analysis showed that the protein content of RVP was low (0.95%).

Electrospun nanofibers as controlled release systems for the combined pheromones of Grapholita molesta and Cydia pomonella.

Background: As sex pheromones are environmentally friendly and specific, they are often used to monitor and control oriental fruit moths (OFMs). Currently, non-biodegradable polymers are commonly employed as carriers to prepare controlled sex pheromone release systems for plant protection. Electrospinning is a relatively simple technique for preparing biodegradable nanofibers that allows for the controlled release of sex pheromones.

Chloroplast antioxidant reactions associated with zinc-alleviating effects on iron toxicity in wheat seedlings.

This study aimed to explore the mechanism by which Zn retards Fe toxicity by analyzing the morphological, photosynthetic, and chloroplast physiological parameters of wheat seedlings treated with either single or combined Zn and Fe. Different behavior of the seedlings was observed under untreated and treated conditions. The most discriminating quantitative traits were associated with leaf area, biomass dry mass and fresh mass, net photosynthetic rate, intercellular CO concentration, stomatal conductance, transpiration rate of seedlings, Hill reaction, Mg-ATPase and Ca-ATPase activities, malondialdehyde and O contents, and glutathione reductase, ascorbate peroxidase, peroxidase, and superoxide dismutase activities and their gene expression in the seedling chloroplast.
