DNA damage induced during mitosis undergoes DNA repair synthesis. [PDF]

open access: yes, 2020
Understanding the mitotic DNA damage response (DDR) is critical to our comprehension of cancer, premature aging and developmental disorders which are marked by DNA repair deficiencies.

Niraparib in ovarian cancer. results to date and clinical potential [PDF]

open access: yes, 2017
Ovarian cancer is the first cause of death from gynaecological malignancy. Germline mutation in BRCA1 and 2, two genes involved in the mechanisms of reparation of DNA damage, are showed to be related with the incidence of breast and ovarian cancer, both ...

Enhanced radiosensitivity of head and neck cancer cells to proton therapy via hyperthermia-induced homologous recombination deficiency

open access: yesClinical and Translational Radiation Oncology
Background and purpose: Radiotherapy induces tumor cell killing by generating DNA double strand breaks (DSBs). The effectiveness of radiotherapy is significantly influenced by the repair of DSBs, which counteracts this lethal effect.

SMYD3 Promotes Homologous Recombination via Regulation of H3K4-mediated Gene Expression

open access: yesScientific Reports, 2017
SMYD3 is a methyltransferase highly expressed in many types of cancer. It usually functions as an oncogenic protein to promote cell cycle, cell proliferation, and metastasis.

A requirement for STAG2 in replication fork progression creates a targetable synthetic lethality in cohesin-mutant cancers. [PDF]

open access: yes, 2019
Cohesin is a multiprotein ring that is responsible for cohesion of sister chromatids and formation of DNA loops to regulate gene expression. Genomic analyses have identified that the cohesin subunit STAG2 is frequently inactivated by mutations in cancer.

Homologous recombination deficiency in triple negative breast cancer

open access: yesThe Breast, 2019
Triple negative breast cancer (TNBC) represents a heterogeneous subtype of breast cancer characterized by an unfavorable prognosis due to its aggressive biology. The median overall survival (OS) for patients with metastatic TNBC is around 9-12 months with conventional cytotoxic agents.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

ATR inhibition preferentially targets homologous recombination-deficient tumor cells [PDF]

open access: yesOncogene, 2014
Homologous recombination (HR) is required for faithful repair of double-strand DNA breaks. Defects in HR repair cause severe genomic instability and challenge cellular viability. Paradoxically, various cancers are HR defective and have apparently acquired characteristics to survive genomic instability.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Patient Assessment and Therapy Planning Based on Homologous Recombination Repair Deficiency

open access: yesGenomics, Proteomics & Bioinformatics, 2023
Defects in genes involved in the DNA damage response cause homologous recombination repair deficiency (HRD). HRD is found in a subgroup of cancer patients for several tumor types, and it has a clinical relevance to cancer prevention and therapies ...
