  We propose two different pathways for the production of this species: either that described by Dooley [24], where the phenol ring is first activated by binding of its oxygen to copper, or one where a copper-peroxo species would directly react with an active site tyrosine residue (Scheme 1B). This se

  Cdc42, which is involved in filopodium formation, and Rac1, which is involved in lamellipodium formation, engage in cross-talk with one another [25,26,30,31]. In general, filopodium formation precedes lamellipodium formation, and filopodium formation (Cdc42 activity) suppresses lamellipodium formati

  Materials and methods Results Because of the specific binding of DGKε to an arachidonoyl group, there was a particular interest to evaluate the behavior of 2-AG with this isoform of DGK. The substrate specificity and kinetic constants for DGKε has been recently reported [13]. Using the preferr

  In conclusion, our results demonstrated that TGF-β1 promotes linear invadosome formation in hepatocellular carcinoma cells, through the regulation of collagen I, its receptor and its cross-linker (Fig. 6). The key role of TGF-β1 in HCC development allow us to suggest that linear invadosomes and thei

  2021-07-28

  

  Uracil residues incorporated into DNA exist transiently since they are subject to removal by the multi-step uracil-initiated DNA annexin v excision repair (BER) process [2], [14]. In E. coli, uracil-DNA BER is initiated by uracil-DNA glycosylase (Ung), which catalyzes the hydrolytic cleavage of the

  Interaction between neutrophils and ECs represents the first step of the cellular phase of the inflammatory response, and provide the best condition for the transfer of the PMNL-derived LTA4 to the ECs, leading to the transcellular formation of cysteinyl-LTs. It is intriguing therefore to think that

  2021-07-28

  

  Cytochromes P450 (CYP 450) are a superfamily of hemoproteins containing a heme cofactor, which are widely distributed in animals, plants and microbes (Hannemann et al., 2007). CYP450 exhibits a variety of biological functions including biotransformation of drugs, detoxification of endogenous and xen

  CYP450s are heme-containing monooxygenases constituting a conserved gene superfamily of heme-thiolate proteins, and are found in prokaryotes and eukaryotes (Martignoni et al., 2006). They play a key role in detoxification of endogenous (e.g., steroids) and exogenous compounds (e.g., drug, insecticid

  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

  Ung et al. examined a variety of structural features based upon the location of the DFG-motif and the αC-helix to define the conformational space of the catalytic domain of protein kinases [75]. They reported that the DFG motif can move from its active DFG-Din location to the inactive DFG-Dout locat

  Many processes can lead to changes in soil P pools over time. Plant-available P (when measured as DGT P) decreased over time for the INORG-P treatment (Fig. 1a). Orthophosphate can be stabilised with cations such as calcium to produce insoluble phosphates, reducing plant-available P (Bünemann et al.

  Both progesterone and the calcium ionophore A23187 rely on the synthesis of cAMP by sAC to elicit exocytosis in human sperm (Fig. 2E-H and [8], [60]). We had reported earlier that digestion of endogenous cAMP with recombinant cAMP-specific phosphodiesterase 4D [9] or inhibition of its synthesis with

  Considering these reports, and with the aim of further investigating the mechanism by which the cAMP-Epac/PKA pathway activates eNOS, we have performed imaging experiments evaluating the effect of drugs that increase cAMP or modify its signalling pathways (PKA or Epac activators and inhibitors) on b
