MitoCareX Bio Study Finds SLC25A as Biomarkers for Spaceflight
N2OFF highlighted a newly published peer-reviewed study co-authored by Prof. Ciro Leonardo Pierri, co-founder of MitoCareX Bio. The article, appearing in the Journal of Translational Medicine, investigates SLC25A mitochondrial carriers as potential biomarkers and therapeutic targets for dysfunctions induced by spaceflight conditions, including microgravity and cosmic radiation. The study, titled "SLC25A mitochondrial carriers as biomarkers and therapeutic targets of spaceflight-induced dysfunction: the ADP/ATP carrier as a structural case study," was published online on December 30. The work integrates transcriptomic data from NASA's Open Science Data Repository, examining the expression of 53 SLC25A genes in osteocytes, human bone marrow-derived mesenchymal stem cells, and mouse brain tissue exposed to microgravity and spaceflight-related stressors. The analysis identified differential regulation of multiple SLC25A carriers under spaceflight conditions, supporting their potential utility as biomarkers of mitochondrial and metabolic dysfunction. The ADP/ATP carrier AAC3 was further examined as a structural case study, based on comparative modeling and structure-function analyses to illustrate how carrier conformational features may be targeted to rescue mitochondrial bioenergetics under stress. While this independent academic research- conducted in collaboration with the University of Bari "Aldo Moro" and the University of Pittsburgh-was not performed under MitoCareX Bio's auspices, it directly aligns with the Company's core scientific area of focus on mitochondrial carrier biology. MitoCareX Bio applies proprietary approaches, including the MITOLINE algorithm to virtually model, screen and validate small-molecule modulators targeting the SLC25A family of mitochondrial carriers. These proteins, central to cellular energy metabolism, play central roles in hard-to-treat indications including in several types of cancer, metabolic diseases related to the metabolic syndrome, and are also implicated in rare inherited disorders associated with neuromuscular degeneration, which share mechanistic similarities with physiological alterations observed in astronauts.
