  Here, we describe preparation of three stable conjugates that are linked by either oxyester, disulfide, or isopeptide bonds (Fig. 10.1). Each of these conjugates depends upon the prior purification of E2 and ubiquitin proteins that have been engineered to favor specific linkages. For the oxyester- a

  Compounds were synthesized using a facile 8-step convergent synthesis ( and ). Briefly, (Boc)cyclen (compound ) was coupled using TBTU to Fmoc- or Cbz-protected amino alkyl acids (–), followed by deprotection using 20% piperidine in DMF, or H on Pd/C, respectively (–) (). Deprotected linkers were co

  2020-12-30

  

  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

  2020-12-30

  

  The discoidin domain receptors, DDR1 and DDR2, are receptor tyrosine kinases (RTKs) that are stimulated by collagen in the extracellular matrix (ECM). Unlike most other RTKs, they form ligand-independent stable dimers that are non-covalently linked. This ECM activation induces receptor phosphorylati

  Conclusions Introduction The terms endocrine active and endocrine disruptive have been used to describe an ever-expanding list of naturally-occurring and synthetic compounds that interact with mammalian hormonal systems, and in particular, the reproductive system. These compounds have been ass

  2020-12-30

  

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  In summary, the reduction of one or more pro-inflammatory cytokines, such as TNF-α, IL-1β, IL-6, IL-8 was observed in almost all the monoterpenes studied. Increased levels of the anti-inflammatory cytokine IL-10 was shown to play a prominent function in the anti-inflammatory effect of monoterpenes,

  Introduction The allergic response is a complex process involving the interaction of several mediators; among these, cysteinyl leukotrienes (CysLTs) represent one of the most important actors in the pathogenesis of airway allergic diseases such as allergic rhinitis and asthma [1]. Pharmacological

  Acknowledgments Casein kinases (CK) are serine/threonine-specific enzymes and can be divided two subtypes: casein kinase 1 (CK1) and casein kinase 2 (CK2). CK1 contains at least seven isoforms (α, β, γ1, γ2, γ3, δ and ε) expressed in eukaryotic organisms, CK1 is involved in various cellular pro

  It has long been known that native BChE is a major factor in the inactivation of cocaine, an ester-type drug of abuse [190]. But recently some researchers conceived the idea that BChE mutations could improve that function to a point that would favorably impact cocaine overdose. Rapid progress was ma

  Effects of estradiol outside the nucleus are often mediated by classical estrogen receptors Today, it is widely accepted that steroid hormones can signal in ways that do not rely on receptors acting in the nucleus, including activation of receptors localized to the cellular membrane. Rapid effect

  The yeast Rad6p (radiation sensitive 6, also called Ubc2) E2 ubiquitin-conjugating enzyme is a member of the highly conserved UBC proteins in eukaryotes (Xu et al., 2009). Rad6p is involved in several cellular processes, including DNA repair, transcriptional activation and silencing, histone ubiquit

  E1 protein expressed in a plasmid encoding codon-optimized canine oral papillomavirus (COPV) led to therapeutic immunization of COPV-infected Beagle dogs [25], [26], which was better than that achieved with plasmids encoding E2 or E7 COPV. Moreover, E1 and E2 from cottontail rabbit papillomavirus (C
