Homologous recombination repairs secondary replication induced DNA double-strand breaks after ionizing radiation
(Oxford University Press, 2012)
Ionizing radiation (IR) produces direct two-ended DNA double-strand breaks (DSBs) primarily repaired by non-homologous end joining (NHEJ). It is, however, well established that homologous recombination (HR) is induced and ...

Metabolic Disturbance of High-Saturated Fatty Acid Diet in Cognitive Preservation
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Aging continues to be the main cause of the development of Alzheimer’s, although it has been described that certain chronic inflammatory pathologies can negatively influence the progress of dementia, including obesity and ...

Arginine deprivation alters microglial polarity and synergizes with radiation to eradicate non-arginine-auxotrophic glioblastoma tumors
(American Society for Clinical Investigation, 2022)
New approaches for the management of glioblastoma (GBM) are an urgent and unmet clinical need. Here, we illustrate that the efficacy of radiotherapy for GBM is strikingly potentiated by concomitant therapy with the ...

The PARP inhibitor Olaparib disrupts base excision repair of 5-aza-2′-deoxycytidine lesions
(Oxford University Press, 2014)
Decitabine (5-aza-21-deoxycytidine, 5-azadC) is used in the treatment of Myelodysplatic syndrome (MDS) and Acute Myeloid Leukemia (AML). Its mechanism of action is thought to involve reactivation of genes implicated in ...

Selective cytotoxic activity and DNA damage by an epoxyalkyl galactopyranoside
(Wiley, 2018)
Several clinically useful anticancer drugs selectively kill cancer cells by inducing DNA damage; the genomic instability and DNA repair defects of cancer cells make them more vulnerable than normal cells to the cytotoxicity ...

The Cockayne syndrome protein B is involved in the repair of 5-AZA-2′-deoxycytidine-induced DNA lesions
(Impact Journals, 2018)
The Cockayne Syndrome Protein B (CSB) plays an essential role in Transcription-Coupled Nucleotide Excision Repair (TC-NER) by recruiting repair proteins once transcription is blocked with a DNA lesion. In fact, CSB-deficient ...

Hydroxyurea-Stalled Replication Forks Become Progressively Inactivated and Require Two Different RAD51-Mediated Pathways for Restart and Repair
(Elsevier, 2010)
Faithful DNA replication is essential to all life. Hydroxyurea (HU) depletes the cells of dNTPs, which initially results in stalled replication forks that, after prolonged treatment, collapse into DSBs. Here, we report ...

Zebularine induces replication-dependent double-strand breaks which are preferentially repaired by homologous recombination
(Elsevier, 2017)
Zebularine is a second-generation, highly stable hydrophilic inhibitor of DNA methylation with oral bioavailability that preferentially target cancer cells. It acts primarily as a trap for DNA methyl transferases (DNMTs) ...

A hydroalcoholic extract from the leaves of Nerium oleander inhibits glycolysis and induces selective killing of lung cancer cells
(Georg Thieme Verlag, 2013)
Recent evidence suggests that cardiac glycosides might be used for the treatment of cancer. The ornamental shrub Nerium oleander has been used in traditional medicine for treating several disorders including cancer, and ...

The Role of DNA Damage Response in Dysbiosis-Induced Colorectal Cancer
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
The high incidence of colorectal cancer (CRC) in developed countries indicates a predominant role of the environment as a causative factor. Natural gut microbiota provides multiple benefits to humans. Dysbiosis is characterized ...
