Fluorescent calixarene-schiff as a nanovehicle with biomedical purposes
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-07-14)
Gene therapy is a technique that is currently under expansion and development. Recent advances in genetic medicine have paved the way for a broader range of therapies and laid the groundwork for next-generation technologies. ...

The Total mRNA Concentration Buffering System in Yeast is Global Rather than Gene-specific
(Cold Spring Harbor Laboratory Press, 2021)
Gene expression in eukaryotes does not follow a linear process from transcription to translation and mRNA degradation. Instead it follows a circular process in which cytoplasmic mRNA decay crosstalks with nuclear transcription. ...

Controlled Transcription of Regulator Gene carS by Tet-on or by a Strong Promoter Confirms Its Role as a Repressor of Carotenoid Biosynthesis in Fusarium fujikuroi
(MDPI, 2020-12)
Carotenoid biosynthesis is a frequent trait in fungi. In the ascomycete Fusarium fujikuroi, the synthesis of the carboxylic xanthophyll neurosporaxanthin (NX) is stimulated by light. However, the mutants of the carS gene, ...

Single cell analysis of bistable expression of pathogenicity island 1 and the flagellar regulon in Salmonella enterica
(MDPI, 2021-01)
Bistable expression of the Salmonella enterica pathogenicity island 1 (SPI-1) and the flagellar network (Flag) has been described previously. In this study, simultaneous monitoring of OFF and ON states in SPI-1 and in the ...

Topoisomerase IIα represses transcription by enforcing promoter-proximal pausing
(Elsevier, 2021)
Accumulation of topological stress in the form of DNA supercoiling is inherent to the advance of RNA polymerase II (Pol II) and needs to be resolved by DNA topoisomerases to sustain productive transcriptional elongation. ...

Functional Characterization of Lysophosphatidylcholine: Acyl-CoA Acyltransferase Genes From Sunflower (Helianthus annuus L.)
(MDPI, 2020)
Lysophosphatidylcholine acyltransferase (LPCAT, EC 2.3.1.23) is an evolutionarily conserved key enzyme in the Lands cycle that catalyzes acylation of lysophosphatidylcholine (LPC) to produce phosphatidylcholine (PC), the ...

Transcription-driven DNA supercoiling counteracts H-NS-mediated gene silencing in bacterial chromatin.
(Nature Research, 2024-03-30)
In all living cells, genomic DNA is compacted through interactions with dedicated proteins and/or the formation of plectonemic coils. In bacteria, DNA compaction is achieved dynamically, coordinated with dense and ...

Transcriptional regulation by the velvet protein VE-1 during asexual development in the fungus neurospora crassa.
(American Society for Microbiology, 2022)
Asexual reproduction in fungi facilitates the dispersal and colonization of new substrates and, in pathogenic fungi, allows infection of plants and animals. The velvet complex is a fungus-specific protein complex that ...

Specificities and Redundancies in the NEL Family of Bacterial E3 Ubiquitin Ligases of Salmonella Enterica Serovar Typhimurium
(Frontiers Media, 2024)
Salmonella enterica serovar Typhimurium expresses two type III secretion systems, T3SS1 and T3SS2, which are encoded in Salmonella pathogenicity island 1 (SPI1) and SPI2, respectively. These are essential virulent factors ...

Calmodulin in Paramecium: Focus on Genomic Data
(MDPI, 2022)
Calcium (Ca2+) is a universal second messenger that plays a key role in cellular signaling. However, Ca2+ signals are transduced with the help of Ca2+-binding proteins, which serve as sensors, transducers, and elicitors. ...
