Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

open access: yesMolecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

SPHINX31 acts as a SRPK1 inhibitor targeting the ATR/DNA‐PKcs/CHK1 replicative checkpoint to inhibit cell growth in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Fertility preservation in women with BRCA1/2‑related cancers: contemporary strategies, international recommendations, and a multidisciplinary approach

open access: yesЮжно-Российский онкологический журнал
Inherited mutations in the BRCA1/BRCA2 genes significantly increase the risk of breast and ovarian cancer in women of reproductive age, posing a clinical and socioeconomic challenge due to loss of fertility during cancer treatment and preventive ...

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).

Treatment with KCL‐286, a first‐in‐class retinoic acid receptor‐β (RARβ) agonist, ameliorates neuronal DNA damage and inflammation in a mouse model of Alzheimer's disease

open access: yesFEBS Open Bio, EarlyView.
Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

BRCA1 and BRCA2 mutations in Scotland and Northern Ireland [PDF]

open access: yes, 2003
BRCA1 and BRCA2 mutations have been identified in 107 families in Scotland and Northern Ireland. Ninety-seven of these families had been referred to regional cancer genetics centres and a further 10 were identified from a sequential series of male breast

Spectrum of pathogenic variants associated with hereditary breast and ovarian cancer in the Republic of Dagestan

open access: yesСибирский онкологический журнал
Background. A significant proportion of patients with breast cancer (BC) and ovarian cancer (OC) are carriers of pathogenic variants in the genes of hereditary cancer syndromes. Most often, hereditary forms of BC and OC are associated with alterations in

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

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
