  Then what is the solution to tackle DNA damage-induced metabolic decline? The culprit here may be not DNA damage signaling per se, but rather the persistent activation of the DNA damage signaling pathways due to age-related accumulation of DNA damage. DNA repair, including repair by NHEJ, is an esse

  In the present work, we ask whether rNMP incorporation is an evolutionarily conserved property of DNA synthesis in Archaea. For this purpose, we used the best characterized hyperthermophilic anaerobe, Pyrococcus abyssi GE5 [47]. This strain duplicates its genome as fast as Bacteria, supported by euk

  The occurrence of three Ag-NORs per metaphase and/or a maximum of three nucleoli per nucleus in most of the varieties may be explained by chromosomal rearrangements or unequal crossing-over events that induce the deletion of the fourth active rDNA loci. Also, the chromosome pair that showed less int

  Several single nucleotide polymorphisms (SNPs) in humans affect CYP3A expression and activity (Lamba et al., 2002). The CYP3A4 SNP rs2740574 (also referred to as CYP3A4*1B, by The Human Cytochrome P450 (CYP) Allele Nomenclature Database, http://www.cypalleles.ki.se/) is a change in the promoter regi

  Atypical collagen glycosylation The disaccharide Glc(α1-2)Gal(β1-O) decorating collagens is strongly conserved across the animal kingdom, yet for every rule, nature provides exceptions. The deep-sea worm Riftia pachyptila of the phylum Annelida represents an intriguing exception. R. pachyptila is

  Perturbations in 3,4-DAA are known to induce apoptosis. Our results show that a fraction of the DT40YB-1b+/− cells, in addition to becoming tetraploids, undergo apoptotic cell death. Similar observations linking polyploidy and apoptosis have been made in the past [23], [30], [31], [32], [33], [34].

  Human neutrophil elastase (HNE) is a serine protease central to the pathology in a wide range of diseases including chronic wounds, cystic fibrosis, and acute respiratory distress syndrome (Owen, 2008). Although neutrophil proteases are necessary for completion of wound healing, HNE is secreted in h

  Some natural products, such as curcumin, resveratrol, and sulforaphane, are known to activate Nrf2 in both in vivo and in vitro experimental models where Nrf2-mediated gene Cyanine 5-dCTP plays a crucial protective role [8]. Under basal conditions, Nrf2 binds to Kelch-like ECH-associated protein 1

  Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In

  The modification of proteins with the small 76-amino 939 protein ubiquitin (Ub) plays a central role in many key cellular processes. Ubiquitylation of a target protein requires the concerted action of a cascade of three enzymes (Figure 1). The ubiquitin-activating enzyme (E1) catalyzes the formatio
