c‐Rel–dependent Chk2 signaling regulates the DNA damage response limiting hepatocarcinogenesis
In response to genotoxic injury, c‐Rel upregulates ATM‐Chk2‐p53 pathway DNA damage proteins to limiting hepatocarcinogenesis. Abstract Background and Aims Hepatocellular carcinoma (HCC) is a leading cause of cancer‐related death. The NF‐κB transcription factor family subunit c‐Rel is typically protumorigenic; however, it has recently been reported as a

Residual Ataxia Telangiectasia Mutated Protein Function in Cells from Ataxia Telangiectasia Patients, with 5762ins137 and 7271T→G Mutations, Showing a Less Severe Phenotype [PDF]
We have assessed several ataxia Telangiectasia mutated (ATM)-dependent functions in cells derived from ataxia telangiectasia patients, carrying either an ATM 5762ins137 splice site or a 7271T-->G missense mutation, with a less severe phenotype compared with the classical disorder.

Selective human inhibitors of ATR and ATM render Leishmania major promastigotes sensitive to oxidative damage. [PDF]
All cellular processes, including those involved in normal cell metabolism to those responsible for cell proliferation or death, are finely controlled by cell signaling pathways, whose core proteins constitute the family of phosphatidylinositol 3-kinase ...

The versatile functions of ATM kinase
Ataxia-telangiectasia mutated (ATM) kinase, the mutation of which causes the autosomal recessive disease ataxia-telangiectasia, plays an essential role in the maintenance of genome stability.

ATM modulates the loading of recombination proteins onto a chromosomal translocation breakpoint hotspot. [PDF]
Chromosome translocations induced by DNA damaging agents, such as ionizing radiation and certain chemotherapies, alter genetic information resulting in malignant transformation. Abrogation or loss of the ataxia-telangiectasia mutated (ATM) protein, a DNA

Somatic role of SYCE2: an insulator that dissociates HP1α from H3K9me3 and potentiates DNA repair
This study reveals that the synaptonemal complex protein SYCE2 potentiates ataxia telangiectasia mutated–mediated DNA double-strand break repair by dissociating HP1α from trimethylated histone H3 lysine 9 in somatic cells.

Dexamethasone Partially Rescues Ataxia Telangiectasia-mutated (ATM) Deficiency in Ataxia Telangiectasia by Promoting a Shortened Protein Variant Retaining Kinase Activity [PDF]
Ataxia telangiectasia (AT) is a rare genetic disease, still incurable, resulting from biallelic mutations in the ataxia telangiectasia-mutated (ATM) gene. Recently, short term treatment with glucocorticoid analogues improved neurological symptoms characteristic of this syndrome. Nevertheless, the molecular mechanism involved in glucocorticoid action in

Spinocerebellar Ataxia Type 1 protein Ataxin-1 is signalled to DNA damage by Ataxia Telangiectasia Mutated kinase [PDF]
ABSTRACT Spinocerebellar Ataxia Type 1 (SCA1) is an autosomal dominant neurodegenerative disorder caused by a polyglutamine expansion in the ataxin-1 protein. Recent genetic correlational studies have implicated DNA damage repair pathways in modifying the age at onset of disease symptoms in SCA1 and Huntington’s ...

Progress towards a clinically-successful ATR inhibitor for cancer therapy
The DNA damage response (DDR) is now known to play an important role in both cancer development and its treatment. Targeting proteins such as ATR (Ataxia telangiectasia mutated and Rad3-related) kinase, a major regulator of DDR, has demonstrated ...

Ataxia‐telangiectasia‐mutated protein expression with microsatellite instability in gastric cancer as prognostic marker [PDF]
The prognostic significance of ataxia‐telangiectasia‐mutated (ATM) expression in gastric cancer remains unclear. The functional loss of ATM gene exhibits a biologic correlation with microsatellite instability (MSI). In this study, we investigated the significance of ATM expression with MSI by evaluating gastric cancer patients who had underwent ...
