DNA REPAIR. Drugging DNA repair.
Inhibiting DNA repair can have a positive outcome on therapeutic interventions All the cells in our bodies suffer many thousands of DNA lesions every day ( 1 ). The vast majority of these lesions are safely dealt with by cellular DNA repair and associated DNA damage response (DDR) activities that are, as a consequence, vital for life.

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.

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.

Oncogenic KRAS supports pancreatic cancer through regulation of nucleotide synthesis
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 ...

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

Homologous recombination (HR)-mediated repair of DNA double-strand break (DSB)s is restricted to the post-replicative phases of the cell cycle. Initiation of HR in the G1 phase blocks non-homologous end joining (NHEJ) impairing DSB repair.

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia
ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.

Targeting DNA Repair, Cell Cycle, and Tumor Microenvironment in B Cell Lymphoma
The DNA double-strand break (DSB) is the most cytotoxic lesion and compromises genome stability. In an attempt to efficiently repair DSBs, cells activate ATM kinase, which orchestrates the DNA damage response (DDR) by activating cell cycle checkpoints ...

Organoids in pediatric cancer research
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.
