Cohesin causes replicative DNA damage by trapping DNA topological stress [PDF]

, 2020
DNA topological stress inhibits DNA replication fork (RF) progression and contributes to DNA replication stress. In Saccharomyces cerevisiae, we demonstrate that centromeric DNA and the rDNA array are especially vulnerable to DNA topological stress ...

DNA Repair in Humans [PDF]

Annual Review of Genetics, 1995
DNA repair is an important molecular defense system against agents that cause cancer, degenerative diseases, and aging. Several repair systems in humans protect the genome by repairing modified bases, DNA adducts, cross links, and double strand breaks.

Compensatory metabolic networks in pancreatic cancers upon perturbation of glutamine metabolism

Nature Communications, 2017
Glutaminase inhibition (GLSi) has promising activity against certain cancers. Here, the authors show that GLSi has no effect on multiple mouse models of pancreatic cancer and characterize the metabolic pathways activated in response to GLSi whose ...

Human Holliday junction resolvase GEN1 uses a chromodomain for efficient DNA recognition and cleavage

eLife, 2015
Holliday junctions (HJs) are key DNA intermediates in homologous recombination. They link homologous DNA strands and have to be faithfully removed for proper DNA segregation and genome integrity.

NBS1 lactylation is required for efficient DNA repair and chemotherapy resistance

Nature
The Warburg effect is a hallmark of cancer that refers to the preference of cancer cells to metabolize glucose anaerobically rather than aerobically1,2.

deconstructSigs: delineating mutational processes in single tumors distinguishes DNA repair deficiencies and patterns of carcinoma evolution

Genome Biology, 2016
Analysis of somatic mutations provides insight into the mutational processes that have shaped the cancer genome, but such analysis currently requires large cohorts.

Oncogenic KRAS supports pancreatic cancer through regulation of nucleotide synthesis

Nature Communications, 2018
Pancreatic ductal adenocarcinoma (PDAC) cells display varying degrees of reliance on oncogenic KRAS. Here the authors show that KRAS-resistant PDAC cells maintain nucleotides synthesis through a KRAS-independent upregulation of the non-oxidative pentose ...

Ribonucleolytic resection is required for repair of strand displaced nonhomologous end-joining intermediates [PDF]

, 2013
Nonhomologous end-joining (NHEJ) pathways repair DNA double-strand breaks (DSBs) in eukaryotes and many prokaryotes, although it is not reported to operate in the third domain of life, archaea. Here, we describe a complete NHEJ complex, consisting of DNA

Putative Role of the Futile Repair Initiated by Human Thymine-DNA Glycosylase in Formation of Programmed Strand Breaks in Neuronal Enhancers [PDF]

BIO Web of Conferences
Enhancers are regulatory DNA elements that play a crucial role in controlling gene expression in specific cell types, including neurons. Enhancer activity is tightly regulated and involves the recruitment of various proteins and enzymes to facilitate the

Functional and conformational impact of cancer-associated SF3B1 mutations depends on the position and the charge of amino acid substitution

Computational and Structural Biotechnology Journal, 2021
The hotspot mutations of SF3B1, the most frequently mutated splicing gene in cancers, contribute to oncogenesis by corrupting the mRNA splicing. Further SF3B1 mutations have been reported in cancers but their consequences remain unclear.
