Eukaryotic Initiation Factor (eIF)
Eukaryotic initiation factors (eIFs) are proteins involved in the initiation phase of eukaryotic translation. These proteins help stabilize the formation of the functional ribosome around the start codon and also provide regulatory mechanisms in translation initiation.
Eukaryotic initiation factor 2B (eIF2B) is a guanine nucleotide-exchange factor which mediates the exchange of GDP (bound to initiation factor eIF2) for GTP, thus regenerating the active [eIF2.GTP] complex that is required for peptide-chain initiation. The activity of eIF2B is a key control point for eukaryotic protein synthesis and is altered in response to viral infection, hormones, nutrients, growth factors and certain stresses.
Eukaryotic translation initiation factor 4E (eIF4E) is best known for its function in the initiation of protein synthesis on capped mRNAs in the cytoplasm. Eukaryotic initiation factor (elF) 4A functions as a subunit of the initiation factor complex elF4F, which mediates the binding of mRNA to the ribosome.

1,2,4-Trihydroxybenzene
0 ImagesSynonyms: Hydroxyhydroquinone1,2,4-Trihydroxybenzene (Hydroxyhydroquinone) is an ER stress inducer that targets proteins such as PKR-like ER kinase PERK to induce cytotoxicity. 1,2,4-Trihydroxybenzene selectively activates eIF2α phosphorylation, activates the PERK-eIF2α signaling pathway and induces stress granule formation. 1,2,4-Trihydroxybenzene subsequently exacerbates oxidative stress and causes DNA double-strand breaks, destroying organelles such as mitochondria and ER, and inducing cell death. 1,2,4-Trihydroxybenzene also has the potential to exhibit anti-tumor effect, increase blood pressure, and relieve spasm.

TBPH
0 ImagesCat. No.: HY-W018587CAS No.: 26040-51-7TBPH is a brominated flame retardant. TBPH enhances hepatic steatosis, inflammation, and fibrosis in mice with nonalcoholic steatohepatitis (NASH). TBPH induces dysregulation of phospholipid metabolism, reducing cardiolipin (CL) and phosphatidylserine (PS) levels. TBPH leads to impaired endoplasmic reticulum-mitochondria (ER-Mito) contacts, subsequently causing mitochondrial dysfunction. TBPH induces lung injury through an inflammatory response mediated by mitochondria-derived ds-DNA. TBPH can be used to study the role of MFN2-mediated ER-mitochondria contacts in lipid metabolism homeostasis.

Flurochloridone decreases Akt, p-Akt, GSK3β, and p-GSK3β levels, and induces ROS, oxidative stress, γ-glutamyl cycle activation, and GSH accumulation. Flurochloridone inhibits mitochondrial respiration and ATP production while enhancing glycolysis and cell viability inhibition. Flurochloridone inhibits spermatogonial proliferation, spermatocyte meiosis, and sperm mitochondrial membrane potential, and induces Sertoli cell apoptosis and mitochondrial damage. Flurochloridone non-competitively binds phytoene desaturase, blocking phytoene desaturation and carotenoid synthesis, leading to leaf bleaching and phytotoxicity. Flurochloridone can be used for research on male reproductive toxicity, hepatotoxicity, and as a herbicide.
