Biosynthesis of the isoprenoid precursor isopentenyl diphosphate (IPP) proceeds via two distinct pathways. Sequence comparisons and microbiological data suggest that multidrug-resistant strains of gram-positive cocci employ exclusively the mevalonate pathway for IPP biosynthesis. Bacterial mevalonate pathway enzymes therefore offer potential targets for development of active site-directed inhib...
p53 is a frequent target for mutation in human tumors, and mutant p53 proteins can actively contribute to tumorigenesis. We employed a three-dimensional culture model in which nonmalignant breast epithelial cells form spheroids reminiscent of acinar structures found in vivo, whereas breast cancer cells display highly disorganized morphology. We found that mutant p53 depletion is sufficient to p...
The mevalonate pathway is highly conserved and mediates the production of isoprenoids, which feed into biosynthetic pathways for sterols, dolichol, ubiquinone, heme, isopentenyl adenine, and prenylated proteins. We found that in Caenorhabditis elegans, the nonsterol biosynthetic outputs of the mevalonate pathway are required for the activity of microRNAs (miRNAs) in silencing their target mRNAs...
Background: Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial glands and stroma surrounded by dense fibrous tissue. Whereas, normal eutopic endometrium shows scarless tissue repair during menstrual cycles, which suggests that the endometriotic tissues have distinct mechanisms of fibrogenesis. During the development of en...
We have previously shown that gene clusters for biosyntheses of terpentecin and BE-40644, a diterpene antibiotic and a sesquiterpene antibiotic, respectively, were located in the adjacent mevalonate pathway gene clusters. In this study, a mevalonate pathway gene cluster was cloned from Streptomyces sp. strain KO-3988, which was known to produce furaquinocin A, employing a hybridization experime...
The early morphogenetic mechanisms involved in heart formation are evolutionarily conserved. A screen for genes that control Drosophila heart development revealed a cardiac defect in which pericardial and cardial cells dissociate, which causes loss of cardiac function and embryonic lethality. This phenotype resulted from mutations in the genes encoding HMG-CoA reductase, downstream enzymes in t...
Here the transcriptome of an oil-rich race B strain of Botryococcus braunii (BOT-70) was analyzed to mine genetic information useful in biofuel development. A full-length-enriched cDNA library was constructed via the oligo-capping method and the 5' ends of 11,904 randomly chosen cDNA clones were sequenced. Homology search using BLASTX identified candidate BOT-70 genes for majority of the reacti...
A mevalonate-independent pathway of isoprenoid biosynthesis present in Plasmodium falciparum was shown to represent an effective target for chemotherapy of malaria. This pathway includes 1-deoxy-D-xylulose 5-phosphate (DOXP) as a key metabolite. The presence of two genes encoding the enzymes DOXP synthase and DOXP reductoisomerase suggests that isoprenoid biosynthesis in P. falciparum depends o...
