Germline variants in CDKN2A wild‐type melanoma prone families

Molecular Oncology, EarlyView.
Among melanoma‐prone families, wild‐type for CDKN2A and CDK4, some have pathogenic variants in genes not usually linked to melanoma. Furthermore, rare XP‐related variants and variants in MC1R are enriched in such families. Germline pathogenic variants in CDKN2A are well established as an underlying cause of familial malignant melanoma. While pathogenic

Spectral Excision and Descent for Almost Perfect Complexes [PDF]

arXiv, 2022
We show that almost perfect complexes of commutative ring spectra satisfy excision and $v$-descent. These results generalize Milnor excision for perfect complexes of ordinary commutative rings and $v$-descent for almost perfect complexes of locally noetherian derived stacks by Halpern-Leistner and Preygel, respectively.

Nucleotide Excision Repair in the Third Kingdom [PDF]

Journal of Bacteriology, 1998
ABSTRACT Nucleotide excision repair, a general repair mechanism for removing DNA damage, is initiated by dual incisions bracketing the lesion. In procaryotes, the dual incisions result in excision of the damage in 12- to 13-nucleotide-long oligomers, and in eucaryotes they result in excision of the damage in the form of 24- to 32-

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

Molecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Mismatch Repair Error Implies Chargaff's Second Parity Rule [PDF]

arXiv, 2007
Chargaff's second parity rule holds empirically for most types of DNA that along single strands of DNA the base contents are equal for complimentary bases, A = T, G = C. A Markov chain model is constructed to track the evolution of any single base position along single strands of genomes whose organisms are equipped with replication mismatch repair ...

Nucleotide Excision Repair in Mammalian Cells [PDF]

Journal of Biological Chemistry, 1997
is found throughout thenatural world in organisms ranging from mycoplasma to mam-mals. In humans, NER is a major defense against the carcino-genic effects of ultraviolet light from the sun. This repair path-way acts with varying efficiencies on a wide variety of DNAalterations and is especially important for bulky, helix-distort-ing lesions.

Involvement of human DNA polymerase kappa in nucleotide excision repair [PDF]

, 2011
Nucleotide excision repair is one of the major repair pathways responsible for identifying and removing lesions in the DNA double helix. In higher eukaryotes, nucleotide excision repair is a coordinated response of over 30 proteins recruited in an ...

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential

Molecular Oncology, EarlyView.
In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

Detecting homologous recombination deficiency for breast cancer through integrative analysis of genomic data

Molecular Oncology, EarlyView.
This study develops a semi‐supervised classifier integrating multi‐genomic data (1404 training/5893 validation samples) to improve homologous recombination deficiency (HRD) detection in breast cancer. Our method demonstrates prognostic value and predicts chemotherapy/PARP inhibitor sensitivity in HRD+ tumours.

Mapping Hsp104 interactions using cross‐linking mass spectrometry

FEBS Open Bio, EarlyView.
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...
