  In our former work, our interest was in discovery of novel VEGFR-2 inhibitors as anti-angiogenesis agents. Along this line, with natural alkaloid taspine as the lead compound, rounds of structure optimization were performed to develop novel VEGFR-2 inhibitors [[13], [14], [15]]. Among them, BPS-7, b

  Films treated with Diaz-ES-VWFIIINle but not exposed to UV light supported only slight platelet deposition, suggesting that passively-bound peptides were removed under shear. However, treatment with Diaz-ES-VWFIIINle and UV restored platelet surface coverage to about 50% of the level on native colla

  In the course of our program, which was aimed at developing CRTH2 antagonists for the treatment of allergic diseases, we have been pursuing a new class of potent and selective CRTH2 antagonist lead based on the structures of CRTH2 antagonists known to date (, , ). Using a fused 6–6-membered ring sys

  2020-03-07

  

  Two isoforms of intracellular ER, ERα, and ERβ, after binding to estrogens and translocate to the nucleus, activate some transcription factors and signaling pathways. The deregulation of estrogenic pathways can elevate transcriptional activity contributed to the development of cancer. Expression of

  The third challenge is to understand the mechanisms of drug resistance. There are several different mechanisms of ES tumor to develop drug resistance. First, cancer stem cells are capable of proliferate and generate tumor cells with new sets of mutations which may harbor different protein targets [1

  EphB4 appears to be a low-affinity receptor for rhEpo based on the biochemical data. The concentration of rhEpo used for the biological experiments (50 IU/ml) corresponds to 10–15 nM, which is 1% to 2% of the KD value (KD = 881 nM) for the binding of rhEpo to EphB4, as measured in the MST assay. The

  It is believed that emphysema in smokers is mediated by proteases released from inflammatory TBCA mg that cause destruction of the extracellular matrix in alveolar septa [1]. Metalloprotease-12 is mainly released by macrophages and is considered the enzyme responsible for emphysematous lesions in e

  Acknowledgments Multicellular organisms respond rapidly, and adapt to cellular stress to maximize cell survival. The cellular stress response, also called (ISR), is universally conserved and independent of the stressor. ISR induces rapid, transient reprogramming of cellular protein translation

  A growing number of other post-translational modifications are implicated in regulation of the ubiquitin system, including substrate modification by hydroxylation, glycosylation, acetylation, methylation, modification by poly(ADP-ribose) (PAR), and attachment of ubiquitin-like modifiers. The HIF1-α

  2020-03-07

  

  Given the important regulatory roles Ub signaling pathways play in eukaryotes, bacterial pathogens and viruses have evolved elaborate mechanisms to hijack host Ub signaling pathways and evade the immune response. This is highlighted by the numerous E3 Ub ligases and spectrum of DUBs encoded by bacte

  DNA-PK After sensing and binding to the DSB, Ku quickly recruits DNA-PKcs to the site of the DNA break. Similar to Ku70/80, recruitment of DNA-PKcs to DSBs occurs within seconds of their creation [12]. The interaction between Ku70/80 and DNA-PKcs requires the presence of dsDNA and the complex for

  In studies directed toward the development of sequence-specific major-groove binding small gli1 [11], we desired a non-intercalating molecular scaffold that could direct attached moieties into the major groove. As an initial step toward this goal, we wished to study the DNA binding mode and affinit

  Nowadays, colorimetric assay has been applied in detecting DNA MTase activity. Li et al. used DNA modified gold nanoparticles (AuNPs) coupled with enzyme-linkage reactions to detect the activity of methylases [20]. In a previous study, our group presented a label-free colorimetric method, using unmo

  Introduction In mammals there are ten known isoforms of the enzyme diacylglycerol kinase (DGK), as well as gene splice variants. Enzymes of this family all have a homologous active site but differ widely in their molecular mass, mechanisms of activation and biological function (Shulga et al., 201
