Gene expression underlying the effects of biotin deficiency in rat liver, worms and yeast

Project description:Biotin is cofactor of crucial enzymes for intermediary metabolism, and its deficiency affects the transcription of some critical genes of mammalian glucose metabolism. However, the precise mechanisms of biotin starvation on gene expression are unknown. Here we show that metabolic changes ushered by deficiency of this vitamin sets in motion extensive reorganization of carbon metabolism gene expression, consistent across three diverse eukaryotes, that is mediated through a regulatory circuitry at the genome level similar in the three species. We used affymetrix microarrays to detail the global gene expression underlying the effects of biotin deficiency in Rattus norvegicus liver, Caenorhabditis elegans and Saccharomyces cerevisiae and identified distinct classes of up-regulated genes during this event.

Effect of biotin deficiency on gene expression in Aravbidopsis leaves

Project description:In addition to its essential metabolic functions biotin is suggested a critical role in regulating gene expression. The first committed enzyme in biotin biosynthesis in Arabidopsis, 7-keto-8-aminopelargonic acid synthase is encoded by At5g04620 (BIO4). We isolated a novel T-DNA insertion mutant of BIO4 (bio4-1) showing a spontaneous cell death phenotype that could be rescued both by exogenous biotin and genetic complementation. The bio4-1 plants exhibited massive accumulation of hydrogen peroxide. The T-DNA insertion in the bio4-1 mutant contains a Methionine Sulfoxide Reductase B9 (AT4G21850) under a constitutive 35S CaMV promoter. To dissect the specific effects of biotin defiency on gene expression on a genome wide scale, we compared expression of wt Col-0 leaves with bio4-1 mutants and bio4-1 mutants complemented with D-biotin.
