Preventive and curative role of a 43 kD protein from the leaves of the herb Cajanus indicus L on thioacetamide-induced hepatotoxicity in vivo
(ELSEVIER IRELAND LTD, 2005-09-01)An approximately 43 kD protein has been isolated and purified from the herb Cajanus indicits L and believed to be the most active principle for its hepatoprotective action. In this study, experiments have been performed ... -
Symbiotic effectiveness of a siderophore overproducing mutant of Mesorhizobium ciceri.
(Polish Society of Microbiologists, 2005)Mutants of Mesorhizobium ciceri BICC 651 were generated by N-methyl-N'-nitro-N-nitrosoguanidine mutagenesis. Siderophore overproducing mutants were identified on Chrome azurol S agar plates. One of them determined as N15 ... -
Regulation of myotrophin gene by pressure overload and stretch
(KLUWER ACADEMIC PUBL, 2004-07-01)Hemodynamic load is a major determinant of cardiac mass and its phenotype, but very little is known about how mechanical load is converted into intracellular signals of gene expression and regulation. We have shown earlier ... -
GaIR represses gaIP1 by inhibiting the rate-determining open complex formation through RNA polymerase contact: A GaIR negative control mutant
(ACADEMIC PRESS, 2004-11-26)Ga1R represses the galP1 promoter by a DNA looping-independent mechanism. Equilibrium binding of Ga1R and RNA polymerase to DNA, and real-time kinetics of base-pair distortion (isomerization) showed that the equilibrium ... -
Cardiac Overexpression of Myotrophin Triggers Myocardial Hypertrophy and Heart Failure in Transgenic Mice
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2004-05-07)Cardiac hypertrophy and heart failure remain leading causes of death in the United States. Many studies have suggested that, under stress, myocardium releases factors triggering protein synthesis and stimulating myocyte ... -
Deterioration of soil physicochemical properties, microbial biomass C, and N-mineralization due to replacement of sal forest with exotic species and rain-fed agriculture in East India
(International Scientific Publications, 2004-03)Effects of conversion of natural forest dominated by Shorea robusta, supported on old alluvial soil, to exotic Eucalyptus tereticornis or Acacia auriculiformis plantation or to agricultural field for cultivation of rice, ... -
Protein-4.2 association with band 3 (AE1, SLCA4) in Xenopus oocytes: Effects of three natural protein-4.2 mutations associated with hemolytic anemia
(AMER SOC HEMATOLOGY, 2005-05-15)We have investigated the effects of coexpression of protein 4.2 and three protein-4.2 variants with band 3 in the Xenopus oocyte expression system. Normal protein 4.2 increased band-3-specific chloride transport in the ... -
Role of C-terminal residues in oligomerization and stability of lambda CII: Implications for lysis-lysogeny decision of the phage
(ACADEMIC PRESS, 2005-01-14)A crucial element in the lysis-lysogeny decision of the temperate coliphage lambda is the phage protein CII, which has several interesting properties. It promotes lysogeny through activation of three phage promoters p(E), ... -
Fas-, caspase 8-, and caspase 3-dependent signaling regulates the activity of the aminophospholipid translocase and phosphatidylserine externalization in human erythrocytes
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2005-11-25)Apoptosis and erythrocyte senescence share the common feature of exposure of phosphatidylserine ( PS) in the outer leaflet of the cells. Western analysis showed that mature red cells contain Fas, FasL, Fas-associated death ... -
Electrostatic potential of nucleotide-free protein is sufficient for discrimination between adenine and guanine-specific binding sites
(ACADEMIC PRESS, 2004-09-17)Despite sharing many common features, adenine-binding and guanine-binding sites in proteins often show a clear preference for the cognate over the non-cognate ligand. We have analyzed electrostatic potential (ESP) patterns ... -
Mycobacterium tuberculosis lipoarabinomannan-mediated IRAK-M induction negatively regulates toll-like receptor-dependent interleukin-12 p40 production in macrophages
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2005-12-30)Mannose-capped lipoarabinomannans (Man-LAMs) are members of the repertoire of Mycobacterium tuberculosis modulins that the bacillus uses to subvert the host innate immune response. Interleukin-12 (IL-12) production is ... -
Luffa sponge - a unique matrix for tissue culture of Philodendron
(CURRENT SCIENCE ASSN, 2004-01-25)An efficient and simple micropropagation protocol of Philodendron 'Xanadu', highly esteemed for its beautiful foliage, has been established. Rapid multiplication was attained by high concentration of N-6-benzyladenine, but ... -
Sequence divergence of Entamoeba histolytica tubulin is responsible for its altered tertiary structure
(ACADEMIC PRESS, 2004-07-02)Atypical microtubular structures of the protozoan parasite Entamoeba histolytica (Eh) have been attributed to amino acid sequence divergence of Eh tubulin. To investigate if this sequence divergence leads to significant ... -
