Summary of "RhTyrRS (Y341A), a novel human tyrosyl-tRNA synthetase mutant, stimulates thrombopoiesis through activation of the VEGF-R II/NF-κB pathway."

Tumor chemotherapy and radiotherapy induces hematopoietic cell damage, resulting in thrombocytopenia. Conventional platelet transfusion strategies or drug therapies are used to treat thrombocytopenia. However, these therapies may result in a several side effects, including heightened susceptibility to infectious diseases and the formation of anti-TPO-antibodies. Therefore, a more secure strategy should be explored to overcome and compensate for the shortcomings of conventional strategies.

Medical and Biotech [MESH] Definitions

A dioxygenase and alkylation repair homolog that catalyzes the methylation of 5-carboxymethyl URIDINE to 5-methylcarboxymethyl uridine at the wobble position of the ANTICODON loop in TRANSFER RNA (tRNA) via its methyltransferase domain. It has a preference for tRNA (ARGININE) and tRNA (GLUTAMATE), and does not bind tRNA (LYSINE).

A modified nucleoside which is present in the first position of the anticodon of tRNA-tyrosine, tRNA-histidine, tRNA-asparagine and tRNA-aspartic acid of many organisms. It is believed to play a role in the regulatory function of tRNA. Nucleoside Q can be further modified to nucleoside Q*, which has a mannose or galactose moiety linked to position 4 of its cyclopentenediol moiety.

An RNA-containing enzyme that plays an essential role in tRNA processing by catalyzing the endonucleolytic cleavage of TRANSFER RNA precursors. It removes the extra 5'-nucleotides from tRNA precursors to generate mature tRNA molecules.

A test used to determine whether or not complementation (compensation in the form of dominance) will occur in a cell with a given mutant phenotype when another mutant genome, encoding the same mutant phenotype, is introduced into that cell.

Intermediates in protein biosynthesis. The compounds are formed from amino acids, ATP and transfer RNA, a reaction catalyzed by aminoacyl tRNA synthetase. They are key compounds in the genetic translation process.
