  • The book Cell Interaction focuses on various processes that occur within and outside the cells. Cell interactions are important for functioning of many organ systems: cell adhesion, tissue development, cellular communication, inflammation, tumor metastasis, and microbial infection. Key features include developmental cell interactions, immune and neural cell interactions, cell interactions in normal and disease conditions and advanced level methods to evaluate cell interactions.

  • VEGF and its receptors are required for vasculogenesis (the de novo formation of blood vessels from differentiating endothelial cells, as occurs during embryonic development) and angiogenesis under normal (wound healing, corpus luteum formation) and pathologic processes (tumor angiogenesis, inflammatory conditions such as rheumatoid arthritis).

  • Estrogen acts as a proconvulsant in several animal models of epilepsy, including amygdalal kindling and pentylenetetrazol administration in ovariectomized rats (Hom and Buterbaugh, 1986). Estrogen induces the formation of new excitatory synapses in the CA1 region of the hippocampus; and further, this estrogenic induction involves activation of Nmethyl- Daspartate (NMDA) receptors (McEwen, 2002). Increasing the complexity of hippocampal synaptic density is likely a mechanism for the proconvulsant activity of estrogen.

  • Pigment epithelium-derived factor (PEDF), a potent blocker of angiogene-sis in vivo, and of endothelial cell migration and tubule formation, binds with high affinity to an as yet unknown protein on the surfaces of endothe-lial cells. Given that protein fingerprinting suggested a match of a 60 kDa PEDF-binding protein in bovine retina withBos taurusF1-ATP synthase b-subunit, and that F1Fo-ATP synthase components have been identified recently as cell-surface receptors, we examined the direct binding of PEDF to F1. ...

  • In two cycles of an error-prone PCR process, variants of formate dehy-drogenase from Candida boidiniiwere created which revealed an up to 4.4-fold (440%) higher residual activity after entrapment in polyacrylamide gels than the wild-type enzyme. These were identified in an assay using sin-gle precursor molecules of polyacrylamide instead of the complete gel for selection.

  • The 6-kDa early secretory antigenic target (ESAT-6) and culture filtrate protein-10 (CFP-10), expressed from the region of deletion-1 (RD1) of Mycobacterium tuberculosisH37Rv, are known to play a key role in viru-lence. In this study, we explored the thermodynamic and biochemical chan-ges associated with the formation of the 1 : 1 heterodimeric complex between ESAT-6 and CFP-10.

  • With current techniques, the risk of graft rejection is 1–3%, and the risk of severe, life-threatening acute GVHD is ~15% following transplantation between HLA-identical siblings. The incidence of graft rejection and GVHD increases progressively with the use of family member donors mismatched for one, two, or three antigens. While survival following a one-antigen mismatched transplant is not markedly altered, survival following two- or three-antigen mismatched transplants is significantly reduced, and such transplants should be performed only as part of clinical trials.

  • Human stefin B, from the family of cystatins, is used as a model amyloido-genic protein in studies of the mechanism of amyloid fibril formation and related cytotoxicity. Interaction of the protein’s prefibrillar oligo-mers⁄aggregates with predominantly acidic phospholipid membranes is known to correlate with cellular toxicity.

  • The functional and structural characterization of G-protein-coupled recep-tors (GPCRs) still suffers from tremendous difficulties during sample preparation. Cell-free expression has recently emerged as a promising alter-native approach for the synthesis of polytopic integral membrane proteins and, in particular, for the production of G-protein-coupled receptors.

  • The naturally synchronous plasmodia of myxomycetes synthesize poly(b-L-malic acid), which carries out cell-specific functions. In Physarum polycephalum, poly(b-L-malate) [the salt form of poly(b-L-malic acid)] is highly concentrated in the nuclei, repressing DNA synthetic activity of DNA polymerases by the formation of reversible complexes. To test whether this inhibitory activity is cell-cycle-dependent, purified DNA polymerase a of P.

  • Loss of tumor suppressors contributes to numerous cancer types. Many, but not all, proteins encoded by tumor suppressor genes have antiproliferative activity and halt cell-cycle progression. In this chapter, we present three methods that have been utilized to monitor the antimitogenic action exerted by tumor suppressors. Tumor suppressor function can be demonstrated by colony formation assays and acquisition of the flat-cell phenotype.

  • Eukaryotic pseudouridine synthases direct RNA pseudouridylation and bind H⁄ACA small nucleolar RNA (snoRNAs), which, in turn, may act as precursors of microRNA-like molecules. In humans, loss of pseudouridine synthase activity causes dyskeratosis congenita (DC), a complex systemic disorder characterized by cancer susceptibility, failures in ribosome biogen-esis and telomere stability, and defects in stem cell formation.

  • Phagocytic cells exposed to exogenous arachidonic acid (AA) incorporate large quantities of this fatty acid into choline and ethanolamine glycero-phospholipids, and into phosphatidylinositol (PtdIns). Utilizing liquid chro-matography coupled to MS, we have characterized the incorporation of exogenous deuterated AA ([ 2 H]AA) into specific PtdIns molecular species in human monocyte cells.

  • Assembly of FtsZ was completely inhibited by low concentrations of urea and its unfolding occurred in two steps in the presence of urea, with the formation of an intermediate [Santra MK & Panda D (2003) J Biol Chem 278, 21336–21343]. In this study, using the fluorescence of 1-anilininonaph-thalene-8-sulfonic acid and far-UV circular dichroism spectroscopy, we found that a natural osmolyte, trimethylamine N-oxide (TMAO), counter-acted the denaturing effects of urea and guanidium chloride on FtsZ....

  • Ribosomes position their substrate at stereochemistry suitable for peptide bond formation, and promote substrate-mediated cata-lysis. The linkage between substrate orientation, dominated by remote interactions, and a sizable symmetrical region identified in all known ribosome structures indicates a guided rotatory motion of aminoacylated-tRNAs along a ribosomal path leadings to the advance of nascent peptides into the protein exit tunnel at an extended conformation.

  • Several transcription factors with the function of setting the biological clock in vertebrates have been described. A detailed understanding of their nucleocytolasmic transport properties may uncover novel aspects of the regulation of the circadian rhythm. This assumption led us to perform a systematic analysis of the nuclear import characteristics of the different murine PER and CRY proteins, usingXenopusoocytes and HeLa cells as experimental systems.

  • Cytidine 5¢-triphosphate synthase catalyses the ATP-dependent formation of CTP from UTP using either ammonia orL-glutamine as the source of nitrogen. When glutamine is the substrate, GTP is required as an allosteric effector to promote catalysis. Limited trypsin-catalysed proteolysis, Edman degradation, and site-directed muta-genesis were used to identify peptide bonds C-terminal to three basic residues (Lys187, Arg429, and Lys432) of Escherichia coliCTP synthase thatwere highly susceptible to proteolysis. ...

  • Antioxidant protein 2 (AOP2) is a member of a family of thiol-specific antioxidants, recently renamedperoxiredoxins, that evolvedas part of anelaborate systemtocounteract and control detrimental effects of oxygen radicals. AOP2 is found in endothelial cells, erythrocytes, monocytes, T andB cells, but not in granulocytes. AOP2 was found solely in the cytoplasm and was not associated with the nuclear or membrane fractions; neither was it detectable in plasma.
