Synonyms: GTP tritris solution (100 mM)
Research Areas:  

Cancer

Guanosine triphosphate tritris (GTP tritris) (100 mM) serves as a vital enhancer of myogenic cell differentiation and plays a critical role in modulating miRNA-myogenic regulator factors. It also facilitates the release of exosomes enriched with guanosine and guanosine-derived molecules, and is regarded as an activated precursor for RNA synthesis. In mitochondrial function, GTP participates in the import of proteins into the matrix, which is essential for various regulated pathways, and is involved in initiating peptide synthesis through the binding of formylmethionyl-tRNA to the ribosome, as well as polypeptide chain elongation. Additionally, GTP acts as a phosphate and pyrophosphate carrier that channels chemical energy into specific biosynthetic pathways. It activates signal transducing G proteins that regulate cellular processes such as proliferation and differentiation, and its hydrolysis by small GTPases, including Ras and Rho, is integral to both proliferation and apoptosis. Furthermore, the small GTPase Rab is instrumental in vesicle docking, fusion, and formation. Beyond signal transduction, GTP is an energy-rich precursor in the enzymatic biosynthesis of DNA and RNA.

Synonyms: Neuropeptide Q
Spexin (Neuropeptide Q) is a selective agonist of galanin receptors GAL2 and GAL3, and is a conserved peptide that functions as a neurotransmitter/neuromodulator and endocrine factor. Spexin can function through both central and peripheral actions. Spexin upregulates Beclin 1 to inhibit ferroptosis induced by excessive autophagy, reduces the uptake of long-chain fatty acids by adipocytes, and regulates energy metabolism by increasing lipid oxidation (e.g., reducing the respiratory exchange ratio in rodents). Spexin improves cardiac function in the Doxorubicin hydrochloride (HY-15142)-induced cardiotoxicity model, protects mitochondrial membrane potential, and reduces iron accumulation and lipid peroxidation. Spexin can be used to study obesity and its related metabolic disorders, cardiovascular diseases (e.g., cardioprotection), and side effects of tumor chemotherapy .
