Suppression of Epidermal Growth Factor Receptor by Erlotinib Attenuates Carvacrol-induced Skin Inflammation.

Epidermal growth factor receptors (EGFRs) regulate the growth and repair process of epithelia, as well as carcinogenesis. Activation of TRPV3 by carvacrol stimulates skin inflammation and epidermal hyperplasia; the latter can be suppressed by EGFR inhibition. However, whether EGFR signalling is responsible for skin inflammation remains elusive.

NIR-II Image-Guided Wound Healing in Hypoxic Diabetic Foot Ulcers: The Potential of Ergothioneine-Luteolin-Chitin Hydrogels.

Hypoxic diabetic foot ulcers (HDFUs) pose a challenging chronic condition characterized by oxidative stress damage, bacterial infection, and persistent inflammation. This study introduces a novel therapeutic approach combining ergothioneine (EGT), luteolin (LUT), and quaternized chitosan oxidized dextran (QCOD) to address these challenges and facilitate wound healing in hypoxic DFUs. In vitro, assessments have validated the biosafety, antioxidant, and antimicrobial properties of the ergothioneine-luteolin-chitin (QCOD@EGT-LUT) hydrogel.

Near-Infrared II Fluorescence Imaging and Image-Guided siRNA Therapy of Atherosclerosis.

Targeting Ca/calmodulin-dependent protein kinase γ (CaMKIIγ) in macrophages using RNAi nanotechnology represents an innovative and promising strategy in the diagnosis and treatment of atherosclerosis. Nevertheless, it remains elusive because of the current challenges associated with the systemic delivery of siRNA nanoparticle (NP) to atheromatous plaques and the complexity of atherosclerotic plaques. Here, we demonstrate the potential of a thienothiadiazole-based near-infrared-II (NIR-II) organic aggregation-induced emission (AIE) platform encapsulated with the Camk2g siRNA to effectively target CaMKIIγ in macrophages for dynamic imaging and image-guided gene therapy of atherosclerosis.

Simultaneous production of high-frequency synthetic apomixis with high fertility and improved agronomic traits in hybrid rice.

The current apomixis system used in fixing heterozygosity suffers from the problems of low fertility and limited apomixis induction rate. This study implies that egg-cell-specific expression of dandelion's PAR combined with MiMe in hybrid rice can efficiently trigger highly fertile synthetic apomixis for effective clonal propagation of hybrids.

TRPV3: Structure, Diseases and Modulators.

Transient receptor potential vanillin 3 (TRPV3) is a member of the transient receptor potential (TRP) superfamily. As a Ca-permeable nonselective cation channel, TRPV3 can recognize thermal stimulation (31-39 °C), and it plays an important regulatory role in temperature perception, pain transduction, skin physiology, inflammation, cancer and other diseases. TRPV3 is not only activated by the changes in the temperature, but it also can be activated by a variety of chemical and physical stimuli.

Biological characterization and fungicide screenings of a new causal agent of wheat Fusarium head blight in Tibet, China.

Wheat ( L.) is an important cereal crop, widely grown throughout the temperate zones, and also suitable for cultivation at higher elevations. Fusarium head blight (FHB) is a highly destructive disease of wheat throughout the globe.

Two distinct Ras genes from Puccinia striiformis exhibit differential roles in rust pathogenicity and cell death.

Ras genes have been shown to regulate a variety of cellular processes in higher eukaryotes. However, much less is known about their function(s) in fungi, especially plant pathogenic fungi. Here, we report the identification and functional analysis of Ras genes from Puccinia striiformis f.

Characterization of protein kinase PsSRPKL, a novel pathogenicity factor in the wheat stripe rust fungus.

As in other eukaryotes, protein kinases (PKs) are generally evolutionarily conserved and play major regulatory roles in plant pathogenic fungi. Many PKs have been proven to be important for pathogenesis in model fungal plant pathogens, but little is currently known about their roles in the pathogenesis of cereal rust fungi, devastating pathogens in agriculture worldwide. Here, we report on an in planta highly induced PK gene PsSRPKL from the wheat stripe rust fungus Puccinia striiformis f.
