  2020-09-04

  

  Functional studies revealed that these ESR1 mutations lead to constitutive activity of the ER, meaning that the receptor is active in absence of estrogen, conferring resistance against several endocrine agents. Recent studies reported that the occurrence of ESR1 mutations is rare in ER+ primary brea

  2020-09-04

  

  Since the number of peptides hydrolized by PEP is quite large, it is not easy to relate the increase of enzymatic activity with the altered changes of a concrete peptide. However, it is noticeable that imbalances of several natural substrates of PEP [6], such as angiotensins, bradykinin, vasopressin

• DNA methylation is associated with transcriptional silencing

  2020-09-04

  

  DNA methylation is associated with transcriptional silencing of tumor suppressors or other genes important for normal cellular function and plays an important role in the development of cancer and other diseases (such as breast and colorectal cancers) [19]. DNA methyltransferases (MTases) are a fami

  P. falciparum DHFR-TS is a particularly important enzyme, because it is from the protozoan species that is associated with most malaria infections. Since this enzyme is responsible for catalyzing sequential reactions in the thymidylate cycle, its inhibition slows malarial dTMP production and therefo

  2020-09-04

  

  An AmDH is engineered by mutating two conserved amino ML-291 residues in the active site of an amino acid dehydrogenase (AADH). Starting from the leucine dehydrogenase (LeuDH) from Bacillus stearothermophilus, substituting a serine and leucine at the K68 and N261 positions, respectively, resulted in

  Nucleophosmin (NPM1), which also plays a role on the nuclear export of ribosomal proteins and subunits (Maggi et al., 2008), is also a relevant MYC target, presumably through an interaction with CRM1. Conversely, it has been recently reported that specific SINE compounds reduce the levels of MYC in

  In the particular case of metals, several authors showed that AChE inhibition is somewhat contradictory and even questionable (Frasco et al., 2005, Nunes et al., 2005, Sáenz et al., 2010). Uranium is a particular metal, and one that has been shown to complex with several biologically important prote

  2020-09-04

  

  Finally, naringin and hesperidin have different glycosidic moieties (neohesperidose α-1,2 and rutinose α-1,6 respectively), bound in the same C7 position on the A ring of the flavonoid. The higher value of k/KM of RHA-Phis towards the former substrate suggests that the enzyme shows a preferential hy

  2020-09-04

  

  The glycolytic pathway is a catabolic route that ends with the synthesis of pyruvate (Pyr). In Arabidopsis embryos, the conversion of phosphoenolpyruvate (PEP) to Pyr, catalyzed by pyruvate kinase (PK), is mainly located in the plastids [10], [11]. The preceding reaction is catalyzed by enolase (ENO

  In order to assess quantitatively the contribution of the ung, dug and dut cyclic amp function to uracil-DNA accumulation in E. coli, we have developed a novel method for measuring uracil residues in DNA that is based on the approach of Kow and co-workers [33] for measuring AP-sites in DNA. The met

  Compounds were prepared via the routes shown in , varying the sequence of reactions to install the thiazole or the phenyl ring at the end of the synthesis (pyridyl examples were prepared using similar chemistry). The aminothiazole building blocks were prepared as shown in . 5-Aminothiazole was prep

  We showed for the first time that ivermectin significantly reduced the pH-induced response of the pHCl-A variant at 300nM, whereas fipronil and γ-BHC had no significant effects on the channel unlike in RDL and GluCl (Fig. 4). Such a concentration is similar to the threshold at which ivermectin activ

• The crystal structure of full length CHK

  2020-09-03

  

  The crystal structure of full-length CHK is still unsolved. However, the close homology between CHK and Csk suggests that these kinases share a similar structure. Therefore, the engagement of the CHK SH2–kinase linker with the αC-helix could control the activity of the CHK kinase domain. Sequence al
