Adaptive response of saccharomyces hosts to totiviridae L-A dsRNA viruses Is achieved through intrinsically balanced action of targeted transcription factors
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Totiviridae L-A virus is a widespread yeast dsRNA virus. The persistence of the L-A virus alone appears to be symptomless, but the concomitant presence of a satellite M virus provides a killer trait for the host cell. The ...

Expression of human RECQL5 in Saccharomyces cerevisiae causes transcription defects and transcription-associated genome instability
(Springer Nature, 2024-05-26)
RECQL5 is a member of the conserved RecQ family of DNA helicases involved in the maintenance of genome stability that is specifically found in higher eukaryotes and associates with the elongating RNA polymerase II. To ...

Physical interactions between specifically regulated subpopulations of the MCM and RNR complexes prevent genetic instability
(Public Library of Science, 2024-05-22)
The helicase MCM and the ribonucleotide reductase RNR are the complexes that provide the substrates (ssDNA templates and dNTPs, respectively) for DNA replication. Here, we demonstrate that MCM interacts physically with RNR ...

BRCA1/BARD1 ubiquitinates PCNA in unperturbed conditions to promote continuous DNA synthesis
(Nature Research, 2024-05-20)
Deficiencies in the BRCA1 tumor suppressor gene are the main cause of hereditary breast and ovarian cancer. BRCA1 is involved in the Homologous Recombination DNA repair pathway and, together with BARD1, forms a heterodimer ...

NR5A2/LRH-1 Regulates the PTGS2-PGE2-PTGER1 Pathway Contributing to Pancreatic Islet Survival and Function
(Elsevier, 2022)
LRH-1/NR5A2 is implicated in islet morphogenesis postnatally, and its activation using the agonist BL001 protects islets against apoptosis, reverting hyperglyce- mia in mouse models of Type 1 Diabetes Mellitus. Islet ...

Roles of Extracellular Vesicles Associated Non-coding RNAs in Diabetes Mellitus
(Frontiers Media SA, 2022)
Extracellular vesicles (EVs), especially exosomes (50 to 150 nm), have been shown to play important roles in a wide range of physiological and pathological processes, including metabolic diseases such as Diabetes Mellitus ...

Enzyme-Responsive Zr-Based Metal-Organic Frameworks for Controlled Drug Delivery: Taking Advantage of Clickable PEG-Phosphate Ligands
(American Chemical Society, 2023)
We report for the first time the controlled drug release from a nanoscale Zr-based metal-organic framework (MOF), UiO-66, in the presence of the enzyme alkaline phosphatase (ALP). This unprecedented reactivity was possible ...
