Analyses of the 5' regulatory sequences of genes encoding barbiturate-inducible cytochromes P450BM-1 and P450BM-3 from Bacillus megaterium and of the 5' sequences of genes for barbiturate-inducible P450b and P450e of the rat revealed a string of 17 base pairs in each of the genes that shared a high degree of sequence identity. Labeled oligonucleotide probes(More)
The gene encoding barbiturate-inducible cytochrome P-450BM-1 from Bacillus megaterium ATCC 14581 has been cloned and sequenced. An open reading frame in the 1.9 kb of cloned DNA correctly predicted the NH2-terminal sequence of P-450BM-1 previously determined by protein sequencing, and, in toto, predicted a polypeptide of 410 amino acid residues with an Mr(More)
In a previous publication (He, J.-S., and Fulco, A. J. (1991) J. Biol. Chem. 266, 7864-7869), we reported that a 15-17-base pair DNA sequence (designated a Barbie box element) in the 5'-regulatory regions of cytochrome P450BM-1 and P450BM-3 genes from Bacillus megaterium was recognized by a barbiturate-regulated protein. It is now recognized that(More)
Analysis of a 1.3-kilobase segment of 5'-flanking DNA from the barbiturate-inducible P450BM-1 gene (CYP106) of Bacillus megaterium revealed two open reading frames. One, BM1P1, encodes 98 amino acids and is located 267 base pairs upstream from the sequence encoding cytochrome P450BM-1 but in the opposite orientation. The second, BM1P2 (88 amino acids), is(More)
In this study, the major antioxidant components of rose flower were identified. An aqueous extract of rose flowers was chromatographed on CM-cellulose in ammonium acetate buffer (10 mM, pH 4.5) to yield three un-adsorbed peaks F1, F2 and F3. Each of these peaks was subjected to gel filtration on Sephadex G75. F1 yielded two peaks, whereas both F2 and F3(More)
BACKGROUND Type I collagen is an interstitial collagen, which is not present in normal glomeruli. As type I collagen was observed in advanced glomerular lesions, it appears to be associated with deterioration of renal function. However, the origins of cells expressing type I collagen mRNA in glomeruli of diseased kidneys remains controversial. METHODS We(More)
Protein gene product 9.5(PGP 9.5) is expressed specifically in neuroendocrine cells and considered to be one of the neuroendocrine markers. Recently, we reported that PGP 9.5 is localized in the parietal epithelial cells(PECs) of Bowman's capsules as well as in neural tissues. In the present study, immunohistochemical analysis of PGP 9.5 as a specific(More)
Hypoxia-inducible factor-1alpha (HIF-1alpha) transcriptionally regulates expression of several target genes in protecting tissues against hypoxia. With hypoxic stress, vascular endothelial growth factor (VEGF) is a signal protein produced by cells and further contributes to improvement of vascular functions and restoring the oxygen supply to tissues. In(More)
The expression and localisation of downstream signalling molecules of transforming growth factor beta superfamily, Smad2 and Smad4 proteins, was investigated in immature and mature dog testis. Cellular localisation of Smad2 and Smad4 proteins was examined using immunohistochemistry. Quantitative analysis of immunostaining was determined by the image(More)
