  2024-09-27

  

  For both, the 17α-hydroxylation and 17, 20-lyase reactions, the heme iron center of P450 17A1 receives electron reducing equivalents from CPR. Both reactions require one pair of electrons and molecular oxygen for the conversion of the substrate into product in each catalytic cycle. However, the 17,2

  2024-09-27

  

  Introduction: the DNA damage response — important implications for tumour development and treatment Cells are invariably challenged by tens of thousands of lesions inflicted on their DNA everyday (Lindhal, 1993). This DNA damage can be caused exogenously by exposure to different types of radiation

  Several alterations have been or can be associated to the decreased tolerance of steatotic liver to I/R injury. Previous studies demonstrated that upregulation of the mitochondrial uncoupling protein-2 (UP2) is strictly related to the increase of I/R injury in steatotic liver [4]. UPR induction is c

  Besides Arg2 overexpression, our data revealed that AGEs could decrease eNOS mRNA levels, which is considered a significant cause for attenuated NO production and vasodilation. It was found recently that AGEs significantly reduce eNOS expression levels and NO bioavailability in human carotid artery

  2024-09-27

  

  Plant tissues were thought to be natural sources containing different types of antioxidant compounds (tocopherols, ascorbic acid, carotenoids, and phenolic compounds). As a general classification, antioxidants were grouped as vitamins (ascorbic acid, tocopherols), carotenoids (condensed tannins, xan

  It is worth noting that in S. cerevisiae, the control of two cell-cycle checkpoints requiring Mcm1 involves two very different mechanisms. At the G1/S transition, Mcm1 transactivation activity is inhibited by Yox1 and Yhp1 repressors, whose expression is periodically regulated through the cell cycle

  2024-09-27

  

  HMGA proteins have also been linked to localized changes in chromatin/nucleosome structure and alterations of cellular phenotype during induction of gene transcription in activated T lymphocytes. An adaptive immune response is initiated when naïve resting T lymphocytes encounter their corresponding

  2024-09-27

  

  Aconitase clusters are prone to oxidations and are among the first to undergo a change in transition state during stages of electrophilic stress rendering them inactive [31]. Aconitase activity in LETO and OLETF did not differ at T0 suggesting that the early onset of insulin resistance may not be at

  2024-09-26

  

  Several mechanisms of Cd-induced carcinogenicity have been reported and are comprehensively summarized by Hartwig [32]. As early as 1980, basic science studies supported a role for endocrine disruption of AR by Cd. Donovan et al. [33], using extracts of mouse prostate cytosol, showed Cd to be the mo

  Ala, a branched chain amino acid, has been reported to play a functional role in intracellular pH regulation, and it typically accumulates in response to various stresses (Limami et al., 2008, Rocha et al., 2010). Our data demonstrated that increasing Cd concentrations at lower Cd doses resulted in

  Conclusion Twenty compounds with 3,5-dinitrobenzoate scaffold were synthesized and evaluated using cell-free and HWB assays for their 5-LOX inhibition activities. Compared to the parent compound, six compounds show significantly increased enzyme inhibition activities. The best compound, 3-tolyl 3,5

  In humans, the major LOs are subdivided by their positional specificity into 5-(ALOX5), 12-(ALOX12) and 15-LO (ALOX15) (Kuhn et al., 2015). 5-LO is the key enzyme for LT biosynthesis and mainly found in mature cells from myeloid origin, including neutrophil, eosinophil and basophil granulocytes, mon

  Despite functional studies demonstrating the role of 5-HT in ureteral contractility, the source of endogenous 5-HT in the ureter is unclear. Since 5-HT-containing enterochromaffin cells, which are present in the gastrointestinal tract, could not be found in the ureter (Nocito et al., 2007, Ripoche,
