  Advantages of modified proteins over unmodified ones In contrast to small-molecule drugs, proteins are readily amenable to site-specific alterations through genetic engineering. In principle, therefore, it is possible to build in features that allow them to remain active for longer in the body an

  Results Discussion The nitric oxide-cyclic guanosine monophosphate pathway plays an important role in normal EF, and oral PDE-5Is were developed in the late 90s after the discovery that ED occurs when there is a problem with this pathway. Since then, several PDF-5Is with different pharmacokine

  2020-12-24

  

  Ligand-independent activation of neuronal nuclear estrogen receptors may also continue to occur in absence of ovarian estrogens. AF-1 requires intracellular kinase cascade-dependent phosphorylation of specific residues in the A/B domain of nuclear estrogen receptors (Le Goff et al., 1994; Kato et al

  Pathophysiology of premature ovarian failure By the age of 40 years, 1% of women spontaneously develop POF [18]. The normal menopause occurs at an average age of 51 years [19] and results from ovarian follicle depletion [20], whereas POF is a heterogeneous disorder and can result from either foll

  2020-12-24

  

  Mammalian cells contain significant amounts of a relatively lesser known enzyme that shows marked specifity for ether lipids containing AA and other 20–22 carbon fatty acids. This enzyme is called CoA-independent transacylase (CoA-IT), and transfers polyunsaturated moieties of 20–22 carbons, typical

  2020-12-24

  

  For most enolases, fluoride acts as an inhibitor, while Mg2+ is the most important metal activator. In yeast systems, metal cations and fluoride bind to enolase at the active center of the enzyme, forming a complex. The complex blocks the binding of substrates to the enzyme in yeast systems, thereby

  High concentrations of 7kC may also arise from dietary intake of processed cholesterol-rich food, likely favoring or worsening inflammatory bowel disease (IBD) [5,13]. Furthermore, IBD has been associated with a dysregulation of colonic 11β-HSD expression, exhibiting increased 11β-HSD1 and decreased

  Structure similarity searches were conducted using the standalone version of the DALI program with the query structures scanned against a local current version of the PDB that has all chains as separate entries (Holm and Sander, 1995). The structural hits for each query were collected, even if the D

  Materials and methods Results Discussion Plant U-box E3 Ub ligases regulate diverse plant-specific cellular processes [1], [2], [3], [4]. However, structural and functional relationships between U-box E3s and their E2 partners are largely unknown in higher plants [24], [25]. In this study,

  2020-12-24

  

  In general, cellular senescence is considered a programmed response to stress that can be activated by oxidative stress, irradiation or action of substances or drugs. These stressors cause DNA damage and, through the action of specific proteins (p53 and p21), lead to cell senescence (di Fagagna, 200

  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

  Introduction Identification and correct storage of seminal stains are crucial for the investigation of sexual assault cases. Actually, undetected ‘cold’ cases involving sexual assault can be solved decades after investigations analysing DNA from stored evidences [1]. Recently, STR analysis and th

  Given the structural similarity of BMAA to other amino acids, our hypothesis was that N-nitrosation of BMAA might result in a toxic alkylating agent, providing a previously unrecognised mechanism for BMAA action. Materials and methods Results and discussion We first examined whether chemical

  MTX and MTXPGs block the activity of the key enzyme DHFR (Fig. 1), which converts folates to their active forms – dihydrofolate (DHF) and tetrahydrofolate (THF). MTXPGs also potently inhibit thymidylate synthase (TS). Furthermore, during dTMP synthesis, TS utilizes the cofactor 5,10-methylene THF, w

  Compound 52 was advanced to a chronic efficacy study in db/db mice maintained on a high fat diet. Animals were dosed with 0.5% methylcellulose vehicle, induced pluripotent stem cells 52 (1, 3 or 15mg/kg, po, Q.D.) or 1 (0.3mg/kg) for 14days. Over the course of the study body weight and food intake
