(Submitter supplied) Purpose: Patients with advanced soft-tissue sarcomas (STSs) exhibit a poor prognosis and have few therapeutic options. DNA-dependent protein kinase catalytic subunit (DNA-PK) is a multifunctional serine—threonine protein kinase that plays a crucial role in DNA double-strand damage repair via nonhomologous end joining (NHEJ). Experimental design: To investigate the therapeutic potential of DNA-PK targeting in STS, we first evaluated the prognostic value of DNA-PK expression in two large cohorts of patients with STS. more...

(Submitter supplied) The non-homologous end-joining (NHEJ) pathway is a major DNA double-strand break repair pathway in mammals and is essential for lymphocyte development. Ku70 and Ku80 heterodimer (KU) initiates NHEJ, thereby recruiting and activating the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs). While DNA-PKcs deletion only moderately impairs end-ligation, the expression of Kinase-dead DNA-PKcs completely abrogates NHEJ. more...

(Submitter supplied) The DNA-dependent protein kinase (DNA-PK), which is composed of the KU heterodimer and the large catalytic subunit (DNA-PKcs), is a classical non-homologous end-joining (cNHEJ) factor. Naïve B cells undergo class switch recombination (CSR) to generate antibodies with different isotypes by joining two DNA double-strand breaks at different switching regions via the cNHEJ pathway. DNA-PK and the cNHEJ pathway play important roles in the DNA repair phase of CSR. more...

(Submitter supplied) In order to identify pathways affected by inhibition of the DNA-dependent protein kinase, catalytic subunit in osteoblasts, we performed a whole genome gene expression profiling using the Affymetrix mouse GeneChip system (MoGene-2.0 gene ST arrays). The osteoblastic cell line MC3T3-E1 was grown in osteogenic medium and treated with DMSO (vehicle) or NU7441, an inhibitor of DNA-dependent protein kinase, for 14 days. more...

(Submitter supplied) The DNA-dependent protein kinase (DNA-PK), composed of the KU heterodimer and the catalytic subunit (DNA-PKcs), is a classical non-homologous end-joining (cNHEJ) factor1. KU binds to DNA ends, initiates cNHEJ, and recruits and activates DNA-PKcs. Beyond DNA, KU also binds to RNA, with unknown significance in mammals. Using mouse models, we uncovered an unexpected role for DNA-PK in ribosomal RNA (rRNA) biogenesis and hematopoiesis. more...

(Submitter supplied) The αNAC (alpha chain of the Nascent polypeptide-Associated Complex) transcriptional coregulator is developmentally expressed in osteoblasts and regulates osteoblast differentiation in vitro and in vivo. αNAC can activate or repress gene transcription, a function that is dynamically regulated by post-translational modification. Phosphorylation of residue Ser132 stimulates the sumoylation of αNAC on Lys127 to repress gene expression. more...

(Submitter supplied) The classical non-homologous end-joining (cNHEJ) pathway is a major DNA double-strand break repair pathway in mammalian cells and is required for lymphocyte development and maturation. The DNA-dependent protein kinase (DNA-PK) is a cNHEJ factor that encompasses the Ku70-Ku80 (KU) heterodimer and the large catalytic subunit (DNA-PKcs). In mouse models, loss of DNA-PKcs (DNA-PKcs-/-) abrogates end-processing (e.g., hairpin-opening), but not end-ligation, while expression of the kinase-dead DNA-PKcs protein (DNA-PKcsKD/KD) abrogates end-ligation, suggesting a kinases-dependent structural function of DNA-PKcs during cNHEJ. more...

(Submitter supplied) The catalytic subunit of DNA-dependent protein kinase (DNA-PKcs) is a classical nonhomologous end-joining (cNHEJ) factor. Loss of DNA-PKcs diminished mature B cell class switch recombination (CSR) to other isotypes, but not IgG1. Here, we show that expression of the kinase-dead DNA-PKcs (DNA-PKcsKD/KD) severely compromises CSR to IgG1. High-throughput sequencing analyses of CSR junctions reveal frequent accumulation of nonproductive interchromosomal translocations, inversions, and extensive end resection in DNA-PKcsKD/KD, but not DNA-PKcs-/- B cells. more...

(Submitter supplied) Hutchinson-Gilford progeria syndrome (HGPS) is a rare and fatal human premature aging disease1-5, characterized by premature atherosclerosis and degeneration of vascular smooth muscle cells (SMCs)6-8. HGPS is caused by a single-point mutation in the LMNA gene, resulting in the generation of progerin, a truncated mutant of lamin A. Accumulation of progerin leads to various aging-associated nuclear defects including disorganization of nuclear lamina and loss of heterochromatin9-12. more...

Analysis of iPSCs generated from fibroblasts from patients with Hutchinson-Gilford progeria syndrome (HGPS), a rare and fatal premature aging disease. Premature aging was recapitulated by differentiation of the HGPS-iPSCs. Results provide insight into molecular mechanisms underlying premature aging.

(Submitter supplied) Full title: Altered levels of MOF (member of MYST family histone acetyl transferase) and decreased levels of H4K16ac correlate with a defective DNA damage response (DDR). The human MOF gene encodes a protein that specifically acetylates histone H4 at lysine 16 (H4K16ac). Here we show that altered levels of H4K16ac correlate with a defective DNA damage response (DDR) to ionizing radiation (IR). The defect however is not due to altered expression of proteins involved in DDR. more...
