2021-09-13
The central event eliciting insulin secretion is the production of ATP which leads to the inhibition of ATP-sensitive inwardly-rectifying K+ATP channels, a consecutive depolarization of the plasma membrane with opening of voltage-dependent Ca2+ channels and Ca2+ influx into the beta-cell. However, i

First identified in 1982 as the second mammalian glutathione peroxidase [23], we and Stockwell's group demonstrated in 2014 that the selenoperoxidase GPX4 is the key upstream regulator of ferroptosis [12], [13]. The role of GPX4 as the main regulator in the ferroptotic process is based on its unique

In principle, an ideal Fenton reaction element should have multiple oxidation states to form a redox cycle in the process of H2O2 decomposition to HO•. Although iron is very effective in catalyzing Fenton reaction, it requires a low pH value (pH 2-4) to reach the optimal catalytic efficiency, which

Recently, the classical view of the compartmentalization of the plant isoprenoid metabolism has been re-evaluated, following the demonstration of the partial peroxisomal localization of the mevalonic SGC 0946 (MVA) pathway, generally regarded as cytosolic. Using GFP-tagging approaches, the last two

Introduction As is now well known, obesity is major risk factor for various diseases such as nonalcoholic fatty liver disease, cardiovascular disease, some cancers (McWilliams and Petersen, 2009), type-2 diabetes mellitus (Jakobsen et al., 2007), and hypertension (Aneja et al., 2004), among other

GSTs have been originally named ‘ligandins’ because of their capacity to bind large ligand molecules (of molecular weight >400 Da) (Oakley et al., 1999). At least three separate AEBSF have been reported for xenobiotics within the H-site; only one is for CDNB (Ralat and Colman, 2004). Usually, the n

GPR35 detection by reverse transcription-polymerase chain reaction (RT-PCR). Total RNA of cultured DRG neurons was extracted using the RNAqueous kit (Ambion). Complementary DNA (cDNA) was synthesized from 1μg of isolated total RNA with SuperScript III reverse transcriptase (Invitrogen). An aliquot o

This evidence suggests that the human cochlea is equipped with antigen presenting macrophages as well as T lymphocytes that execute cytotoxic and immune mediation function. In an animal study, following acoustic overstimulation, Yang et al. (2015) found infiltration of macrophages into the region of

Cell origin The ontogeny of astrocytes in vitro has been investigated in detail; Raff et al. (1983) characterised two types of astrocytes: type 1 being fibroblast-like in morphology and poorly labelled with a monoclonal antibody (AB25), whereas type 2 exhibited oligodendrocyte or neuron-like morp

In addition to the increase of extracellular glutamate, ICH can also increase the levels of reactive oxygen species (ROS) and oxidative stress. Although the products of red blood cell lysis and plasma components, as well as the excitotoxic effect of glutamate have been to increase oxidative damage (

Traditional methods for HATs activity assays mainly depend on radioisotope labelling of histone substrates, which is limited by the complex procedures, hazards and wastes of radioactive materials. Hence, various alternative approaches such as electrochemical analysis, fluorescence and colorimetric a

Introduction Histamine stored in mast cells and basophils has been recognized as one of the most critical mediators in allergic reactions and plays an important role in eliciting the nasal symptoms of allergic rhinitis, such as sneezing, nasal itch, pain, rhinorrhea, and congestion [1], [2]. It i
