  N-Cyclopentylmethyl analog 25 exhibited 2.3-fold less potent receptor affinity and 1.6-fold less potent antagonist activity. Among the compounds tested, the N-isobutyl analog 23 showed the most potent EP1 receptor affinity and antagonist activity. In summary, a series of 4-( 2-[alkyl(phenylsulfonyl

  Another important new result that has expanded the range of functions of iPLA2-VIA in physiology and pathophysiology is its implication in macrophage polarization under stimulation conditions. Ashley et al. [129] described in peritoneal macrophages from Pla2g6−/− mice that the absence of iPLA2-VIA f

  Nrf2 and HO-1 are key factors in the regulation of oxidative stress in the body. Research has shown that KLF2 can activate Nrf2 and HO-1 [14]. To investigate the mechanisms by which KLF2 regulates eNOS uncoupling and oxidative stress, Nrf2 was inhibited or HO-1 was knocked down in KLF2 overexpressin

  Recently, a non-proteolytic role of COP1 in stabilizing PIF3 proteins in the dark has been revealed . Previous studies have shown that the endogenous levels of PIF3 protein in etiolated seedlings were nearly undetectable . Ling found that the GSK3-like kinase BRASSINOSTEROID-INSENSITIVE 2 (BIN2) pla

  2020-12-25

  

  There is a functional ubiquitin association (UBA) domain at the N terminus of MCPIP1. Liang et al. have discovered that MCPIP1 may be a deubiquitinase and defined a novel DUB domain of MCPIP1 [22]. Ubiquitin and deubiquitin modification emerge as the key mechanisms that regulate the virus-induced ty

  Another example of negative regulation is the inhibition of the yeast endosome-associated DUB Doa4 by Rfu1 (free ubiquitin chains 1). In a yeast genetics screen, deletion of Rfu1 was serendipitously found to alter global ubiquitin levels [69]. DUBs can regulate these levels by liberating conjugated

  GLP-1 also showed cardioprotective effects (i.e., infarct size reduction and ejection fraction improvement) in experimental models of myocardial ischemia-reperfusion injury by suppressing caspase-3 activation and preventing apoptosis of cardiomyocytes [[50], [51]]. Of note, such a cardioprotection w

  In this work, we directly compared the effects on transcription by E. coli RNAP of several types of lesions commonly found in the genomic DNA: thymine dimer (CPD, cyclobutane pyrimidine dimer); 1,N6-ethenoadenine (εA); abasic site (AP); 8-oxoguanine (8oxoG), and thymine glycol (TG).

  Besides chemopreventive effects against oxidative DNA damage we evaluated the protective effects of the three Hypericum sp. and isolated compounds against alkylating DNA damage induced by MMS in HT29 cells. Human exposure to alkylating agents, from different sources, occurs in a continuous way and i

  It has been reported that vernolic 1478 accumulation in transgenic Arabidopsis seeds expressing a Δ12-epoxygenase often resulted in failure of germination and impaired growth and development (Singh et al., 2001). Similar phenomena were also reported for transgenic Arabidopsis seeds with accumulatio

  Introduction The Discoidin Domain Receptors (DDRs), comprising DDR1 and DDR2, are collagen-binding receptor tyrosine kinases (RTKs) that function as microenvironmental sensors at the interface of the extracellular matrix and the intracellular signal transduction machinery [1]. In response to ligand

  By stratifying EOC cell lines according to their EMT stages, we observed a significant higher expression of DDR1 in the epithelial-like cell lines compared to low or undetectable DDR1 in mesenchymal-like cell lines. Similar trend was observed in the tumour samples, with the lowest expression of DDR1

  In summary, our data show a novel mechanism: CPD-mediated autoprocessing of C difficile toxins regulates their proinflammatory activities. Thus, our study provides a new understanding of the molecular mechanisms of the pathogenesis of C difficile toxins and insights into designing new therapeutics a
