Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Molecular Mechanisms of the Whole DNA Repair System: A Comparison of Bacterial and Eukaryotic Systems

Journal of Nucleic Acids, 2010
DNA is subjected to many endogenous and exogenous damages. All organisms have developed a complex network of DNA repair mechanisms. A variety of different DNA repair pathways have been reported: direct reversal, base excision repair, nucleotide excision ...

Pluripotent cells display enhanced resistance to mutagenesis

Stem Cell Research, 2017
Pluripotent cells have been reported to exhibit lower frequencies of point mutations and higher levels of DNA repair than differentiated cells. This predicts that pluripotent cells are less susceptible to mutagenic exposures than differentiated cells. To

Mechanisms of glycosylase induced genomic instability. [PDF]

PLoS ONE, 2017
Human alkyladenine DNA glycosylase (AAG) initiates base excision repair (BER) to guard against mutations by excising alkylated and deaminated purines. Counterintuitively, increased expression of AAG has been implicated in increased rates of spontaneous ...

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

, 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.

[Base excision repair].

Postepy biochemii, 2005
Damage to DNA bases resulting from deamination, oxidation, and alkylation is mainly repaired by base-excision repair. BER is initiated by DNA glycosylases, which recognize damaged bases and excise them from DNA by hydrolyzing the N-glycosidic bond between the base and the sugar phosphate backbone of DNA to generate an abasic site. Different human and E.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.
