Study TitleMetabolomic profiling of PMM2-CDG zebrafish in presence and absence of epalrestat
Study SummaryAbnormal polyol metabolism has been predominantly associated with diabetes, where excess glucose is converted to sorbitol by aldose reductase (AR). Recently, abnormal polyol metabolism has also been implicated in phosphomannomutase 2-congenital disorder of glycosylation (PMM2-CDG), and epalrestat, an AR inhibitor, proposed as a potential therapy for this disorder. Given that the PMM enzyme is not closely connected to polyol metabolism, and, unlike in diabetes, PMM2-CDG does not present with hyperglycemia in blood, the increased polyol production, and the therapeutic mechanism of epalrestat in PMM2-CDG remained largely elusive. PMM2-CDG is caused by deficiency of the PMM enzyme and results in a depletion of mannose-1-P and guanosine diphosphate mannose (GDP-mannose), which is essential for glycosylation. Here, we show that apart from glycosylation abnormalities, PMM2 deficiency also leads to changes in intracellular glucose flux, which results in an increase in intracellular polyols. Targeting AR with epalrestat decreases polyol levels and increases GDP-mannose in vivo in pmm2 mutant zebrafish.
