Atherosclerosis is a complex disease that gene and environment interaction influences the progression of atherosclerotic lesion development. Our laboratory used mice lacking both the low density lipoprotein (LDL) receptor and Apobec1 genes (LDLR-/-Apobec1-/-, designated LDb) to investigate gene-gene interaction and the influence of an environmental factor(More)
An aryl aldehyde oxidoreductase from Nocardia sp. strain NRRL 5646 was purified 196-fold by a combination of Mono-Q, Reactive Green 19 agarose affinity, and hydroxyapatite chromatographies. The purified enzyme runs as a single band of 140 kDa on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The molecular mass was estimated to be 163 +/- 3.8 kDa(More)
MOTIVATION Analysis of statistical properties of DNA sequences is important for evolutional biology as well as for DNA probe and PCR technologies. These technologies, in turn, can be used for organism identification, which implies applications in the diagnosis of infectious diseases, environmental studies, etc. RESULTS We present results of the(More)
Animal models provide vital tools to explicate the pathogenesis of atherosclerosis. Accordingly, we established two atherosclerosis-prone mice models: (i) mice lacking the LDL (low-density lipoprotein) receptor (LDLR) and the ability to edit apo (apolipoprotein) B mRNA (Apobec1; designated LDb : LDLR-/- Apobec1-/-), and (ii) mice with the LDb background,(More)
Although complement activation and deposition have been associated with a variety of glomerulopathies, the pathogenic mechanisms by which complement directly mediates renal injury remain to be fully elucidated. Renal parenchymal tissues express a limited repertoire of receptors that directly bind activated complement proteins. We report the renal expression(More)
A large number of plant microRNAs (miRNAs) are now documented in the miRBase, among which only 30 are for Solanum lycopersicum (tomato). Clearly, there is a far-reaching need to identify and profile the expression of miRNAs in this important crop under various physiological and pathological conditions. In this study, we used an in situ synthesized custom(More)
The conversions of vanillic acid and O-benzylvanillic acid to vanillin were examined by using whole cells and enzyme preparations of Nocardia sp. strain NRRL 5646. With growing cultures, vanillic acid was decarboxylated (69% yield) to guaiacol and reduced (11% yield) to vanillyl alcohol. In resting Nocardia cells in buffer, 4-O-benzylvanillic acid was(More)
A new one-pot synthesis was designed to prepare benzoyl-AMP under anhydrous conditions in N,N-dimethylformamide. Reaction of benzoic acid with N,N'-carbonyldiimidazole and subsequently with 5'-adenosyl monophosphate gave the mixed anhydride in 76% isolated yield. The structure of benzoyl-AMP was confirmed by mass spectroscopy and 1H-, 31P-, and 13C-NMR. The(More)
Transcriptional analysis was used to examine the effect of a genomically encoded artificial RNA on Escherichia coli in rich and minimal media. Only the expression of a single gene, deoC, was unequivocally affected under both conditions. E. coli marker strains of this type may be useful in monitoring the fate and transport of bacteria in various applications.
A comparative statistical analysis of the presence of all possible short subsequences of length 5 to 20 nucleotides in the genomes of more than 250 microbial, viral and multicellular organisms was performed. A remarkable similarity of the presence/absence distributions for different n-mers in all genomes was found. The same analysis applied analytically and(More)
