  In the present study, cells were exposed to a low level of arsenite and a low cytotoxic concentration of BaP. Thus, γ-H2AX loss correlated with repair of DNA damage in cells co-exposed to arsenite and BaP. These results show that arsenite inhibits repair of BaP-induced DNA damage. In a previous stud

  In SLO-permeabilized human sperm, the AR elicited by calcium, persistently active Arf6 [41] and Rab3A, 8-pCPT-2′-O-Me-cAMP [8], diacylglycerol and a non-hydrolyzable analog [35], is sensitive to the PLC blocker U73122. Furthermore, 8-pCPT-2′-O-Me-cAMP elicits a calcium signal in non-permeabilized sp

  There are two types of DDRs, DDR1 and DDR2, which are type I transmembrane RTKs characterized by an N-terminal extracellular discoidin domain containing a collagen binding site [8]. DDR1 expression is somewhat restricted to epithelial cells, while DDR2 is often expressed in cells of mesenchymal orig

  Moving forward, the new mathematical model opens doors for understanding the SCF network, where activity of a component is blunted through mutation or altered in expression in diseased states, and during therapeutic intervention. Computational modeling could reveal underappreciated secondary or tert

  2020-03-27

  

  How does APC/C recognize its substrates and catalyze their ubiquitylation? How are the outcomes and timing of these activities regulated? These questions have driven a decade of structural studies that begin to explain how APC/C interacts with coactivators, substrates, and E2s, and how these interac

  E3–E2 backside interaction The E2 possesses an important regulatory interface which is termed its backside as it is opposite to the catalytic cleft that bears the active-site cysteine forming the thioester with SUMOD. This backside site interacts noncovalently with a scaffold SUMOB and was origin

  p27Kip1 is a critical component of the cell cycle machinery [15]. As an inhibitor of cyclin E-Cdk2, p27Kip1 plays a pivotal role in controlling cell proliferation, S-phase entry, and G1-phase exit during development and tumorigenesis [16]. p27Kip1 is predominantly regulated via posttranslational mod

  Although the control group and tinnitus group do not significantly differ based on age, gender or hearing loss, a limitation of this study is that the control group is only group-matched, and not individually matched. Furthermore, we only tested hearing acuity in tinnitus patients via standard pure

  Organ fibrosis is thought to be initiated by repeated or chronic epithelial injury. The current belief is that damaged epithelial Boc-D-Asp(OtBu)-OH.DCHA induce an aberrant and unresolved wound repair process by activating fibroblasts via various profibrotic cues. Upon injury, epithelial cells acti

  Nuclear estrogen receptors: Indirect genomic signaling As mentioned earlier, the transcription of several genes that do not contain EREs in their promoter regions can also be regulated by estradiol, without direct binding of the estrogen receptors to the DNA. According to the most recent reports,

  Another option is to use the thiol groups of cysteine residues, which can be modified by use of PEG-maleimide and vinyl sulfone. However, changes in PEGylation interactions or reaction conditions can result in changes in the functional properties of the therapeutic proteins [[50], [51], [52]]. A st

  In summary, this is the first report describing the enzymatic characteristics, binding activity and localization of T. solium enolase. Here we demonstrate that Tseno gene possesses classical features of enolase family with highly conserved active sites, Mg2+ binding and plasminogen-binding motifs. T

  Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

  Introduction DNA ligation is required during DNA replication and to complete almost all DNA repair events. In human cells, the DNA ligases encoded by three LIG genes are responsible for joining interruptions in the phosphodiester backbone [1]. These enzymes have distinct but overlapping functions
