Název v původním jazyce

Ultrastructure of Cytoplasmic and Nuclear Inosine-5 '-Monophosphate Dehydrogenase 2 "Rods and Rings" Inclusions

Popis výsledku v původním jazyce

Inosine-5-monophosphate dehydrogenase catalyzes the critical step in the de novo synthesis of guanosine nucleotides: the oxidation of inosine monophosphate to xanthosine monophosphate. This reaction can be inhibited by specific inhibitors, such as ribavirin or mycophenolic acid, which are widely used in clinical treatment when required to inhibit the proliferation of viruses or cells. However, it was recently found that such an inhibition affects the cells, leading to a redistribution of IMPDH2 and theappearance of IMPDH2 inclusions in the cytoplasm. According to their shape, these inclusions have been termed Rods and Rings (R&R). In this work, we focused on the subcellular localization of IMPDH2 protein and the ultrastructure of R&R inclusions. Usingmicroscopy and western blot analysis, we show the presence of nuclear IMPDH2 in human cells.
