Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

open access: yesMolecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

TP53 loss initiates chromosomal instability in fallopian tube epithelial cells

open access: yesDisease Models & Mechanisms, 2021
High-grade serous ovarian cancer (HGSOC) originates in the fallopian tube epithelium and is characterized by ubiquitous TP53 mutation and extensive chromosomal instability (CIN).

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Breast cancer risk and 6q22.33: combined results from breast cancer association consortium and consortium of investigators on modifiers of BRCA1/2 [PDF]

open access: yes, 2012
Recently, a locus on chromosome 6q22.33 (rs2180341) was reported to be associated with increased breast cancer risk in the Ashkenazi Jewish (AJ) population, and this association was also observed in populations of non-AJ European ancestry. In the present

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

open access: yesMolecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

H4K20me0 recognition by BRCA1-BARD1 directs homologous recombination in sister chromatids

open access: yesNature Cell Biology, 2019
Genotoxic DNA double-strand breaks (DSBs) can be repaired by error-free homologous recombination (HR) or mutagenic non-homologous end-joining1. HR supresses tumorigenesis1, but is restricted to the S and G2 phases of the cell cycle when a sister ...

Male Breast Carcinoma after Irradiation and Long-Term Phenothiazine Exposure: A Case Report

open access: yesCase Reports in Oncology, 2020
We present a young male patient with breast cancer having several risk factors likely acting in consort: irradiation of the breast for gynecomastia in adolescence and a life-long administration of phenothiazine for schizophrenia from the age of 16 years,

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

open access: yesAging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Genetic Epidemiology of BRCA1 [PDF]

open access: yesCancer Biology & Therapy, 2004
Since the identification of the BRCA1 gene 10 years ago much has been learned about the role of the BRCA1 protein in cancer development. In particular, genetic and epidemiological approaches have informed about the spectrum of mutations that occur in the gene and the prevalence, penetrance, and phenotype associated with these mutations in various ...

A Case of Triple-Negative Breast Cancer with Germline Pathogenic Variants in Both BRCA1 and BRCA2

open access: yesCase Reports in Oncology, 2021
We report a rare case of hereditary breast and ovarian cancer syndrome (HBOC) with pathogenic variants in both BRCA1 and BRCA2. The patient was a 78-year-old woman who visited the hospital after noticing a lump in her left breast 6 months before, which ...
