Yeast Sen1 helicase protects the genome from transcription-associated instability
(Elsevier, 2011-01-06)
Sen1 of S. cerevisiae is a known component of the NRD complex implicated in transcription termination of nonpolyadenylated as well as some polyadenylated RNA polymerase II transcripts. We now show that Sen1 helicase possesses ...

EXOSC10 is required for RPA assembly and controlled DNA end resection at DNA double-strand breaks
(Nature Research, 2019)
The exosome is a ribonucleolytic complex that plays important roles in RNA metabolism. Here we show that the exosome is necessary for the repair of DNA double-strand breaks (DSBs) in human cells and that RNA clearance is ...

Regulation of bistability in the std fimbrial operon of Salmonella enterica by DNA adenine methylation and transcription factors HdfR, StdE and StdF
(Oxford Academic, 2019-09-05)
Bistable expression of the Salmonella enterica std operon is controlled by an AND logic gate involving three transcriptional activators: the LysR-type factor HdfR and the StdE and StdF regulators encoded by the std operon ...

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, ...

DNA Double Strand Breaks and Chromosomal Translocations Induced by DNA Topoisomerase II
(Frontiers Media, 2019)
DNA double strand breaks (DSBs) are the most cytotoxic lesions of those occurring in the DNA and can lead to cell death or result in genome mutagenesis and chromosomal translocations. Although most of these rearrangements ...

A genome-wide function of THSC/TREX-2 at active genes prevents transcription–replication collisions
(Oxford University Press, 2014)
The THSC/TREX-2 complex of Saccharomyces cerevisiae mediates the anchoring of transcribed genes to the nuclear pore, linking transcription elongation with mRNA export and genome stability, as shown for specific reporters. ...

CYK4 inhibits Rac1-dependent PAK1 and ARHGEF7 effector pathways during cytokinesis
(Rockefeller University Press, 2012)
In mitosis, animal cells lose their adhesion to the surrounding surfaces and become rounded. During mitotic exit, they reestablish these adhesions and at the same time physically contract and divide. How these competing ...

Molecular Pathways Leading to Induction of Cell Death and Anti-Proliferative Properties by Tacrolimus and mTOR Inhibitors in Liver Cancer Cells
(1421-9778, 2020)
Background/Aims: Orthotopic liver transplantation (OLT) is the recommended treatment for patients at early stages of hepatocarcinoma (HCC) with portal hypertension and/or increased bilirubinemia, but without ...

Roles of human POLD1 and POLD3 in genome stability
(Nature, 2016)
DNA replication is essential for cellular proliferation. If improperly controlled it can constitute a major source of genome instability, frequently associated with cancer and aging. POLD1 is the catalytic subunit and POLD3 ...
