Erasure coding is widely used for massive storage in data centers to achieve high fault tolerance and low storage redundancy. Since the cross-rack communication cost is often high, it is critical to design erasure codes that minimize the cross-rack repair bandwidth during failure repair. In this paper, we analyze the optimal trade-off between storage redundancy and cross-rack repair bandwidth s...
Chronic inflammation is a driving force for gastric carcinogenesis. Reactive oxygen species (ROS) generated during the inflammatory process generates DNA damage that is processed through the DNA repair pathways. In this study, we profiled key DNA repair proteins (single-strand-selective monofunctional uracil-DNA glycosylase 1 [SMUG1], Flap endonuclease 1 [FEN1], X-ray repair cross-complementing...
The forkhead box M1 (FoxM1) transcription factor regulates expression of cell cycle genes essential for DNA replication and mitosis during organ repair and cancer progression. Here, we demonstrate that FoxM1-deficient (-/-) mouse embryonic fibroblasts and osteosarcoma U2OS cells depleted in FoxM1 levels by small interfering RNA transfection display increased DNA breaks, as evidenced by immunofl...
X-ray repair cross-complementing group 1 (XRCC1) and xeroderma pigmentosum group D (XPD) are mainly involved in base excision repair (BER) and nucleotide excision repair (NER) of DNA repair pathways, respectively. Polymorphisms of DNA repair gene XRCC1 and XPD has recently been identified, and there is a growing body of evidence that these polymorphisms may have some phenotypic significance. To...
OBJECTIVES Coronary artery disease (CAD) is the leading cause of death in both male and female worldwide. The main cause of CAD is the atherosclerosis of coronary arteries, which is, mostly caused by genetic alteration. 50% of such cases occur in mitotic cells where single-strand breaks occur spontaneously or due to ionizing radiation. X-ray repair cross-complementing protein 1 (XRCC1) as a key...
Cisplatin is a crucial agent in the treatment of many solid tumors, yet many tumors have either acquired or intrinsic resistance to the drug. We have used the homozygous diploid deletion pool of Saccharomyces cerevisiae, containing 4728 strains with individual deletion of all nonessential genes, to systematically identify genes that when deleted confer sensitivity to the anticancer agents cispl...
BACKGROUND Suture pretension during tendon repair is supposed to increase the resistance to gap formation. However, its effects on the Bunnell suture technique are unknown. The purpose of this study was to determine the biomechanical effects of suture pretension on the Bunnell and cross-lock Bunnell techniques for tendon repair. METHODS Eighty porcine hindlimb tendons were randomly assigned t...
SV40-transformed normal, xeroderma pigmentosum (XP) and Fanconi's anemia (FA) fibroblasts have distinct repair capacities for monoadducts and DNA interstrand cross-links produced by exposure to near-UV (320-400 nm) light in the presence of 8-methoxypsoralen or angelicin. Excision repair of monoadducts occurred rapidly in normal and FA cells after exposure but not in XP cells. Cross-links were r...
a better understanding of the mechanism of chromosomal aberration formation could be obtained by using dna repair inhibitors. immortalized normal human (mrc 5 svi) and ataxia telangiectasia ( at 5 biv a ) fibroblastic cell lines were treated with adenosine arabinoside (ara-a) and cytosine arabinoside (ara-c), both potent inhibitors of dna dsb repair, alone or in combination with x-rays at g2 or...
