| Study Title | ADSL deficiency drives mitochondrial dysfunction and ERK2 dysregulation in a linear genotype to phenotype correlation |
| Study Summary | Adenylosuccinate lyase (ADSL) deficiency (ADSLd) is a rare autosomal recessive defect of purine metabolism associated with a wide range of clinical manifestations. Despite ADSL implication in purine synthesis, no additional molecular alterations have been identified as a cause of ADSLd besides the accumulation of toxic substrates. Here we uncover a novel association between ADSLd and mitochondrial dysfunction, which is characterized by an increase in fragmentation and reduction in respiration and ATP production. The extent of this mitochondrial dysfunction is directly proportional to the pathological manifestations of ADSLd, which are predominantly observed in tissues that rely heavily on mitochondria. Our analysis also unveils a striking defect in mitochondrial dynamics and transport, which are associated with the suppression of ERK2 and AKT function. Remarkably, the mitochondrial phenotype can be rescued in part by overexpression of a constitutive form of ERK2 or through the administration of purine intermediates. This scenario provides an alternative explanation of ADSLd onset, reorienting research towards developing innovative therapeutic strategies based on the restoration of mitochondrial metabolism. |

| Collection ID: | CO003461 |
| Collection Summary: | 2x105 cells were plated onto 60mm plates in DMEM media (5 replicates for each cell type). After two days, before extraction, cells were counted using CASY cell counter (Omni Life Sciences) using a separate counting plate. After that, cells were washed at room temperature with PBS twice and then kept in a cold bath with dry ice and methanol before adding the metabolite extraction solution. |
