Regulation of Glycosylphosphatidylinositol-Anchored Protein (GPI-AP) Expression by F-Box/LRR-Repeat (FBXL) Protein in Wheat ( L.).

F-box proteins are substrate recognition components of the Skp1-Cullin-F-box (SCF) complex, which performs many important biological functions including the degradation of numerous proteins via the ubiquitin-26S proteasome system. In this study, we isolated the gene encoding the F-box/LRR-repeat (FBXL) protein from wheat ( L.) seedlings and validated that the TaFBXL protein is a component of the SCF complex.

Effects of Proton Irradiation on the Current Characteristics of SiN-Passivated AlGaN/GaN MIS-HEMTs Using a TMAH-Based Surface Pre-Treatment.

However, the relationship of HR and NHEJ in DNA damage stress is unknown in the radiation-resistant fungus .

Protective Effect of Polysaccharides Extracted from Fruit against Cisplatin-Induced Cytotoxicity in Macrophages and a Mouse Model.

Although cisplatin is one of most effective chemotherapeutic drugs that is widely used to treat various types of cancer, it can cause undesirable damage in immune cells and normal tissue because of its strong cytotoxicity and non-selectivity. This study was conducted to investigate the cytoprotective effects of fruit-derived polysaccharides (CTPS) against cisplatin-induced cytotoxicity in macrophages, lung cancer cell lines, and a mouse model, and to explore the possibility of application of CTPS as a supplement for anticancer therapy. Both cisplatin alone and cisplatin with CTPS induced a significant cytotoxicity in A549 and H460 lung cancer cells, whereas cytotoxicity was suppressed by CTPS in cisplatin-treated RAW264.

Investigation of Antifungal Mechanisms of Thymol in the Human Fungal Pathogen, .

Due to lifespan extension and changes in global climate, the increase in mycoses caused by primary and opportunistic fungal pathogens is now a global concern. Despite increasing attention, limited options are available for the treatment of systematic and invasive mycoses, owing to the evolutionary similarity between humans and fungi. Although plants produce a diversity of chemicals to protect themselves from pathogens, the molecular targets and modes of action of these plant-derived chemicals have not been well characterized.

Regulation of Dual Activity of Ascorbate Peroxidase 1 From by Conformational Changes and Posttranslational Modifications.

Ascorbate peroxidase (APX) is an important reactive oxygen species (ROS)-scavenging enzyme, which catalyzes the removal of hydrogen peroxide (HO) to prevent oxidative damage. The peroxidase activity of APX is regulated by posttranslational modifications (PTMs), such as S-nitrosylation, tyrosine nitration, and S-sulfhydration. In addition, it has been recently reported that APX functions as a molecular chaperone, protecting rice against heat stress.

Measurement of Genetic Mobility Using a Transposon-Based Marker System in Sorghum.

Transposable elements (TEs) are ubiquitous repetitive components of eukaryotic organisms that show mobility in the genome against diverse stresses. TEs contribute considerably to the size, structure, and plasticity of genomes and also play an active role in genome evolution by helping their hosts adapt to novel conditions by conferring useful characteristics. We developed a simple and rapid method for investigation of genetic mobility and diversity among TEs in combination with a target region amplification polymorphism (TE-TRAP) marker system in gamma-irradiated sorghum mutants.
