Association between transcriptional activity, local chromatin structure, and the efficiencies of both subpathways of nucleotide excision repair of melphalan adducts.
The repair of melphalan-induced N-alkylpurine monoadducts and interstrand cross-links was examined in different repair backgrounds, focusing on four genes (beta-actin, p53, N-ras, and delta-globin) with dissimilar transcription activities. Adducts were found to be substrates for both global genome repair (GGR) and transcription-coupled repair (TCR), with TCR being less efficient than GGR. In nu...
متن کاملEfficient Realization of Givens Rotation through Algorithm-Architecture Co-design for Acceleration of QR Factorization
We present efficient realization of Generalized Givens Rotation (GGR) based QR factorization that achieves 3-100x better performance in terms of Gflops/watt over state-of-the-art realizations on multicore, and General Purpose Graphics Processing Units (GPGPUs). GGR is an improvement over classical Givens Rotation (GR) operation that can annihilate multiple elements of rows and columns of an inp...
متن کاملConstructing tailored isoprenoid products by structure-guided modification of geranylgeranyl reductase.
The archaeal enzyme geranylgeranyl reductase (GGR) catalyzes hydrogenation of carbon-carbon double bonds to produce the saturated alkyl chains of the organism's unusual isoprenoid-derived cell membrane. Enzymatic reduction of isoprenoid double bonds is of considerable interest both to natural products researchers and to synthetic biologists interested in the microbial production of isoprenoid d...
متن کاملImpact of global genome repair versus transcription-coupled repair on ultraviolet carcinogenesis in hairless mice.
The nucleotide excision repair (NER) system is comprised of two subpathways, i.e., transcription-coupled repair (TCR) and global genome repair (GGR). To establish the relative importance of TCR and GGR for UV effects on the skin, we have used hairless knockout mouse strain lacking either TCR (CSB -/-) or GGR (XPC -/-). In single exposure experiments, we found that CSB -/- mice have a 7-16 times...
متن کاملNon-transcribed strand repair revealed in quiescent cells.
Stem cells, one of the progenitors of cancer, exist predominately in a quiescent state. Thus, understanding the mechanisms of DNA repair and mutagenesis in such arrested cells may help unravel the complex process of tumorigenesis. Two major nucleotide excision repair (NER) pathways are known to remove bulky physical or chemical lesions from DNA. Transcription-coupled repair (TCR) acts solely on...
