Characterisation of XPD from Sulfolobus acidocaldarius : an iron-sulphur cluster containing DNA repair helicase [PDF]
, 2007 DNA is constantly damaged by a variety of exogenous and endogenous sources. To maintain the integrity of the genome, different DNA repair mechanisms have evolved, which deal with different kinds of DNA damage.

PANoptosis in the pathogenesis of myelodysplastic syndromes
Molecular Oncology, EarlyView.PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Current role of mammalian sirtuins in DNA repair
, 2019 Cellular DNA is constantly challenged by damage-inducing factors derived from exogenous or endogenous sources. Thus, to protect against DNA damage, cells have evolved complex and finely regulated mechanisms collectively known as DNA-damage response (DDR).

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Enhancement of therapeutic transgene insertion for treatment of murine phenylketonuria
Molecular Therapy: Nucleic AcidsLow in vivo transgene integration frequency limits the therapeutic efficacy of homology-directed repair (HDR) as a treatment for genetic disorders. This study demonstrates improved efficacy of HDR-mediated gene insertion for the treatment of murine ...

Molecular 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 ...

Recruitment kinetics of DNA repair proteins Mdc1 and Rad52 but not 53BP1 depend on damage complexity. [PDF]
, 2012 The recruitment kinetics of double-strand break (DSB) signaling and repair proteins Mdc1, 53BP1 and Rad52 into radiation-induced foci was studied by live-cell fluorescence microscopy after ion microirradiation.

Molecular Oncology, EarlyView.Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Biochemical characterization and DNA repair pathway interactions of Mag1-mediated base excision repair in Schizosaccharomyces pombe [PDF]
, 2005 The Schizosaccharomyces pombe mag1 gene encodes a DNA repair enzyme with sequence similarity to the AlkA family of DNA glycosylases, which are essential for the removal of cytotoxic alkylation products, the premutagenic deamination product hypoxanthine ...
