Covalent Inhibitor Screening for Targeting LOXL2: Studied by Virtual Screening and Experimental Validation.

Background: Lysyl oxidase-like 2 (LOXL2) is a metalloenzyme that catalyzes oxidative deamination ε-amino group of lysine. It has been found that LOXL2 is a promotor for the metastasis and invasion in kinds of tumors. Previous studies show that disulfide bonds are important components in LOXL2, and their bioactivity can be regulated by those bonds.

Gibberellin promotes xylem expansion and cell lignification by regulating sugar accumulation and the expression of JcMYB43 and JcMYB63 in the woody plant Jatropha curcas.

Gibberellins (GAs) are a group of diterpene plant hormones that regulates various plant developmental processes, including wood formation. Nevertheless, the regulatory pattern and the downstream targets of GA in the regulation of xylem expansion and cell lignification in woody plants remains unclear. In transgenic Jatropha curcas with significantly increased or decreased bioactive GA content via separate overexpression of JcGA20ox1 or JcGA2ox6, comparative transcriptomic, metabolomic and physiological investigations were conducted on the young stems.

Disrupted methionine cycle triggers muscle atrophy in cancer cachexia through epigenetic regulation of REDD1.

The essential amino acid methionine plays a pivotal role in one-carbon metabolism, facilitating the production of S-adenosylmethionine (SAM), a critical supplier for DNA methylation and thereby a modulator of gene expression. Here, we report that the methionine cycle is disrupted in skeletal muscle during cancer cachexia, leading to endoplasmic reticulum stress and DNA hypomethylation-induced expression of the DNA damage inducible transcript 4 (Ddit4) gene, encoding the regulated in development and DNA damage response 1 (REDD1) protein. Targeting DNA methylation by depletion or pharmacological inhibition of DNA methyltransferase 3A (DNMT3A) exacerbates cachexia, while restoring DNMT3A expression or REDD1 knockout alleviates cancer cachexia-induced skeletal muscle atrophy in mice.

Effects of refrigeration and freezing on milk fat globule membrane lipids in stored breast milk: Insights from non-targeted lipidomics.

Breast milk storage provides flexibility for working mothers, though its effects on milk fat globule membrane (MFGM) lipids are not fully understood.

Microstructured Liquid Metal-Based Embedded-Type Sensor Array for Curved Pressure Mapping.

Human hands can envelop the surface of an object and recognize its shape through touch. However, existing stretchable haptic sensors exhibit limited flexibility and stability to detect pressure during deformation, while also solely achieving recognition of planar objects. Inspired by the structure of skin tissue, an embedded construction-enabled liquid metal-based e-skin composed of a liquid metal microstructured electrode (LM-ME) array is fabricated for curved pressure mapping.

Therefore, this study selected recombinant human H-chain ferritin (rHuHF), rHuHF encapsulated with resveratrol (rHuHF-Res), and rHuHF-dextran glycoconjugates loaded with resveratrol (Dex-rHuHF-Res) as emulsifiers to investigate their interfacial adsorption properties.

Combined transcriptomic, metabolomic and physiological analysis reveals the key role of nitrogen, but not phosphate and potassium in regulating anthocyanin biosynthesis induced by nutrient deficiency in Eucalyptus.

Anthocyanin biosynthesis in Eucalyptus plants can be flexibly and rapidly modulated in response to hormones or environmental stimuli, including nutrient deprivation (ND). However, the underlying mechanism of ND in inducing anthocyanin biosynthesis in plants remains largely elusive. In this study, we discovered that anthocyanin levels in leaves and stems could well reflect nitrogen availability in Eucalyptus.
