Proteome analysis and morphological studies reveal multiple effects of the immunosuppressive drug mycophenolic acid specifically resulting from guanylic nucleotide depletion.
Mycophenolic acid (MPA), one of the most promising immunosuppressive drugs recently developed, is a potent inhibitor of IMP dehydrogenase, the first committed step toward GMP synthesis. We found that all the drug effects on yeast cells were prevented by bypassing GMP synthesis, thus confirming the high specificity of MPA. Although the primary target of MPA is clearly identified, we aimed to fur...
متن کاملPhenotypic consequences of purine nucleotide imbalance in Saccharomyces cerevisiae.
Coordinating homeostasis of multiple metabolites is a major task for living organisms, and complex interconversion pathways contribute to achieving the proper balance of metabolites. AMP deaminase (AMPD) is such an interconversion enzyme that allows IMP synthesis from AMP. In this article, we show that, under specific conditions, lack of AMPD activity impairs growth. Under these conditions, we ...
متن کاملEffects of Phenylglyoxal and N-ethylmaleimide Concentration on Mycophenolic Acid Production by Penicillium brevi-compactum ATCC16024
Mycophenolic acid is a secondary extracellular metabolite of Penicillium strains with numerous pharmaceutical properties such as antibiotic and immunosuppressive uses. The aim of this work is the survey of the effect of phenylglyoxal and n-ethylmaleimide concentration in culture medium on mycophenolic acid production by Penicillium brevi-compactum ATCC16024 was investigated. Batch submerged fer...

متن کاملThe Influence of Immunosuppressive Drugs on Vascular Endothelial Growth Factor Production in Relation to VEGF - 1154 G and -2578 C Genotypes
Background: The pathogenesis of many diseases is correlated to irregularity in vascular endothelial growth factor (VEGF) expression. Results from several association studies show that variation in the level of VEGF expression is related to polymorphic sequences within the VEGF gene. Additionally, there are many studies showing that some gene polymorphisms significantly influence the pharmacokin...
