Glycogen Metabolism May Go Awry Before Symptoms Appear in Pompe

A number of enzymes involved in synthesizing glycogen – the molecule that accumulates to toxic levels in Pompe disease – are elevated in a mouse model of the disease and these metabolic changes may contribute to the disease’s progression, a study found. In fact, the buildup of these proteins…

UK Trial Testing MRI Tool Seeks LOPD Patients, Healthy Volunteers

A small study in the U.K. is evaluating a noninvasive MRI-based tool that could potentially detect late-onset Pompe disease (LOPD) without the need for invasive muscle biopsies. This specialized muscle MRI also would monitor glycogen buildup — a hallmark of the condition — in muscles over time. The…

Patient-derived Nerve Cells May Help Advance Pompe Research

Newly developed nerve cells derived from patients could be used as a model to study neurological involvement in Pompe disease and test potential therapies, a study reports. Notably, data from these models suggested that a combination of two molecules, which was previously shown to have beneficial effects in models of…
