  Concluding Remarks The effects of point mutations of the four ARs on ligand binding affinities, functional potencies, and efficacies constitute a valuable source of pharmacological information. We analyzed the existing data and mapped it on the collection of available AR crystal structures, allow

  2024-10-11

  

  The synthesis and secretion of adrenal androgens is apparently unique to humans and nonhuman primates, and requires the expression of key mediators such as CYP17 [26]. Endocrine control of CYP17 expression in rhesus monkeys is comparable to that in humans [27]. An analysis of baboon cDNA for CYP17

  Cancer Lsodren manifest characteristic abnormal growth properties accompanying clonal evolution of cells displaying progressively increasing genomic instability capable of invasion and metastasis to distant organ sites. With the emerging knowledge about the role of known oncogene and tumor suppresso

  Synthetic lethal approaches In addition to the potential utility of ATM and ATR as chemo- or radiosensitisers, recent studies suggest that such compounds may have single agent activity in certain subsets of patients through induction of synthetic lethality. Two genes are considered synthetically

  Arginases from several species and tissues have been found to be inhibited by amino acids [51]. In the present study, monocarboxyilic amino acids with five or more carbon atoms such as ornithine, lysine, valine, leucine and isoleucine inhibited CL-ARG. The results revealed that as the amino ion chan

  Introduction Endothelial progenitor cells (EPCs) present a class of blood cells with an ability to form new blood vessels relying on pre-existing vessels, which contribute to postnatal angiogenesis [1], [2]. A wide range of studies have demonstrated that EPCs play a critical role in angiogenesis

  Over expression of the inflammatory cytokines, MMPs and COX-2 act as an important inducer of chronic inflammation. COX-2 catalyzes the biosynthesis of prostaglandins (PGs), and induced expression was observed in tak tak stimulated with pro-inflammatory cytokines or bacterial lipopolysaccharide (Kha

  2024-10-10

  

  The zinc transporter proteins are members of the SLC superfamily of metal transporters, and comprise two structurally and functionally different groups, the zinc-importer (ZIP; Zrt-, Irt-like proteins) family (SLC39A), which regulate zinc transport into the cytoplasm from outside the cell and from i

  PGC-1α-mediated mitochondrial biogenesis in brown fat and endothelial 3,3',5'-Triiodo-L-thyronine is in part regulated by eNOS and NO [28], [29]. Recent studies indicate that H2S not only augments NO bioavailability and signaling [11], [17], but provides protection against cardiac injury in an eNOS

  Similarly, results obtained in our lab using experimental diabetic encephalopathy induced by streptozotocin (STZ) in C57BL-6 mice showed that the hippocampus of the diabetic animals exhibited reactive gliosis, neuronal loss, NF-kB signaling activation as well as high levels of IL-1β and vascular end

  Introduction Nonalcoholic fatty liver disease (NAFLD) is a clinicopathologic spectrum of liver pathologies associated with excessive accumulation of fat in the liver. This spectrum is continuous but can be graded based on pathological features; in increasing severity, these are: bland steatosis,

  Secondly, as pointed out by Sulentic and Kaminski in their recent paper [90], most of the AhR literature to date has focused on mouse AhR. Although both mouse and human AhR are interchangeable in many in vitro systems, the in vivo ligand binding affinity is drastically different between the two AhRs

  Aberrant or a sustained activation of AhR signaling pathway, triggered by exogenous toxic ligands such as dioxins, PAHs or polychlorinated biphenyls (PCBs), is a well-described biological process engaged during tumor initiation and/or promotion in various tissues (e.g. liver, lung, skin)(reviewed in
