Differential release of extracellular vesicle tRNA from oxidative stressed renal cells and ischemic kidneys

open access: yesScientific Reports, 2022
While urine-based liquid biopsy has expanded to the analyses of extracellular nucleic acids, the potential of transfer RNA (tRNA) encapsulated within extracellular vesicles has not been explored as a new class of urine biomarkers for kidney injury. Using

Maf1, repressor of tRNA transcription, is involved in the control of gluconeogenetic genes in Saccharomyces cerevisiae [PDF]

open access: yesGene, 2013
Maf1 is a negative regulator of RNA polymerase III (Pol III) in yeast. Maf1-depleted cells manifest elevated tRNA transcription and inability to grow on non-fermentable carbon source, such as glycerol. Using genomic microarray approach, we examined the effect of Maf1 deletion on expression of Pol II-transcribed genes in yeast grown in medium containing

An Adaptive Reference Vector Adjustment Strategy and Improved Angle-Penalized Value Method for RVEA

open access: yesComplexity, 2021
Decomposition-based evolutionary multiobjective algorithms (MOEAs) divide a multiobjective problem into several subproblems by using a set of predefined uniformly distributed reference vectors and can achieve good overall performance especially in ...

maf1 mutation alters the subcellular localization of the Mod5 protein in yeast.

open access: yesActa Biochimica Polonica, 1994
Two forms of Mod5p, a tRNA modification enzyme, are found in three intracellular compartments, mitochondria, cytoplasm and nucleus, but are encoded by a single MOD5 gene. The two forms of the enzyme, Mod5p-I and Mod5p-II differ at the N-termini and are produced by initiation of translation at different start codons. Mod5p-I does contain a mitochondrial

Maf1 Is an Essential Mediator of Diverse Signals that Repress RNA Polymerase III Transcription [PDF]

open access: yesMolecular Cell, 2002
Maf1 is a putative repressor of RNA polymerase (pol) III transcription that is conserved from yeast to humans. Here we show that Maf1 is a common component of multiple signaling pathways in S. cerevesiae that sense changes in the cellular environment and repress pol III transcription.

TORC2 and the AGC kinase Gad8 regulate phosphorylation of the ribosomal protein S6 in fission yeast

open access: yesBiology Open, 2012
Summary TOR (Target Of Rapamycin) signalling coordinates cell growth and division in response to changes in the nutritional environment of the cell. TOR kinases form two distinct complexes: TORC1 and TORC2.

Engineering Saccharomyces cerevisiae for the production of the valuable monoterpene ester geranyl acetate

open access: yesMicrobial Cell Factories, 2018
Background Geranyl acetate is widely used in the fragrance and cosmetic industries, and thus has great economic value. However, plants naturally produce a mixture of hundreds of esters, and geranyl acetate is usually only present in trace amounts, which ...

Fabrication and characterization of solid lipid nano-formulation of astraxanthin against DMBA-induced breast cancer via Nrf-2-Keap1 and NF-kB and mTOR/Maf-1/PTEN pathway

open access: yesDrug Delivery, 2019
In the current experimental study, we scrutinized the chemoprotective effect of astraxanthin against the 7,12-dimethylbenz(a)anthracene (DMBA)-induced breast cancer via Nrf-2-Keap1 and NF-kB and mTOR/Maf-1/PTEN pathway.

Characterization of a MAF1 knockout mouse model [PDF]

open access: yes, 2015
L'ARN polymérase 3 transcrit un petit groupe de gènes fortement exprimés et impliqués dans plusieurs mécanismes moléculaires. Les ARNs de transfert ou ARNt représentent plus ou moins la moitié du transcriptome de l'ARN polymérase 3. Ils sont directement impliqués dans la traduction des protéines en agissant comme transporteurs d'acides aminés qui sont ...

Robust repression of tRNA gene transcription during stress requires protein arginine methylation

open access: yesLife Science Alliance, 2019
This work examines how protein arginine methylation of Rpc31, a subunit of RNA Pol III, promotes negative regulation of tRNA biogenesis in the context of cellular stress. Protein arginine methylation is an important means by which protein function can be
