DeCure for Combined oxidative phosphorylation deficiency 52
DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for combined oxidative phosphorylation deficiency 52 — screening already-approved drugs against its 1-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.
Disease moduleCombined oxidative phosphorylation deficiency 52 maps to a 1-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead
No approved-drug candidate for combined oxidative phosphorylation deficiency 52 is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.
Molecular view
NFS1 cysteine desulfurase (NFS1) — NFS1 is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to
Combined oxidative phosphorylation deficiency 52 is a mitochondrial disorder caused by defects in the OXPHOS system, which consists of five multiprotein complexes and two mobile electron carriers in the mitochondrial inner membrane. The system is under dual genetic control, meaning inheritance can be maternal, autosomal, or X-linked. Identifying the genetic defect underlying a combined OXPHOS deficiency is difficult due to the multitude of proteins and processes involved in mitochondrial translation and OXPHOS biogenesis. The abstracts provide no specific data on survival, response rates, or sample sizes for this particular deficiency.
One 2021 study of 85 endometrial carcinoma patients found that copy-number-high tumours reflect TP53 inactivation, and that TP53-inactive tumours have poor prognosis. In those tumours, activation of oxidative phosphorylation was observed, and the authors suggested the PI3K/mTOR and autophagy pathways as potential drug targets. This study does not address combined oxidative phosphorylation deficiency 52, and its findings on OXPHOS activation in cancer are not directly applicable to a primary OXPHOS deficiency disorder.
A 2004 review summarises the genetic understanding of OXPHOS enzyme deficiencies and notes that many cases remain genetically unresolved, with special emphasis on complex I biogenesis. A 2009 communication gives an overview of proteins and processes involved in combined OXPHOS deficiencies, stating that further research into genetic causes is needed for prevention and cure. No treatment or efficacy data for any drug are reported in any of these abstracts.
What is still missing: dedicated funding for genetic discovery in combined OXPHOS deficiencies, well-designed natural history studies with patient stratification by genetic subtype, and any clinical trial testing a specific intervention for this disorder.

Genetic defects in the oxidative phosphorylation (OXPHOS) system
AbstractThe oxidative phosphorylation (OXPHOS) system consists of five multiprotein complexes and two mobile electron carriers embedded in the lipid bilayer of the mitochondrial inner membrane. With the exception of complex II and the mobile carriers, the other parts of the OXPHOS system are under dual genetic control. Due to this bigenomic control, the inheritance of OXPHOS system defects is either maternal, in the case of mitochondrial DNA mutations, autosomal or X-linked, in the case of nuclear gene defects. In this review, our current genetic understanding of OXPHOS system enzyme deficiencies will be summarized, and future directions that the field might take to unravel so-far genetically unresolved OXPHOS system enzyme deficiencies will be described, with special emphasis on complex I biogenesis.

Activation of oxidative phosphorylation in TP53-inactive endometrial carcinomas with a poor prognosis
Abstract<h3>Objective</h3> We aimed to identify pathways for potential therapeutic targets by conducting molecular profiling of endometrial carcinomas in patients with poor prognosis. <h3>Methods</h3> The classification of endometrial carcinomas has undergone a paradigm shift with the advent of next generation sequencing based molecular profiling. Although this emerging classification reflects poor prognosis in patients with endometrial carcinoma, knowledge of affected biological pathways is still lacking. In this study, 85 patients with endometrial carcinomas at the Shizuoka Cancer Center were evaluated from January 2014 to March 2019 and classified based on The Cancer Genome Atlas subgroups. The accumulation of germline and somatic mutations was determined using next generation sequencing. Gene expression profiling was used to determine the effect of TP53 inactivation on the recurrence of endometrial carcinoma. Additionally, the biological pathways associated with TP53 inactivation were estimated by pathway analysis based on gene expression. <h3>Results</h3> Based on The Cancer Genome Atlas classification, the ratio of polymerase-epsilon to copy number-high subgroups and the frequency of <i>PTEN</i> and <i>TP53</i> mutations differed in patients, and mutations of <i>ARHGAP35</i> observed in normal endometrium were accumulated in the polymerase-epsilon and microsatellite instability subgroups. We revealed that copy number-high reflects TP53 inactivation in endometrial carcinomas, and that TP53-inactive tumors with or without <i>TP53</i> mutations have poor prognosis. Furthermore, overexpression of aurora kinase A and activation of oxidative phosphorylation were found in TP53-inactivated endometrial carcinomas, suggesting that the PI3K/mTOR and autophagy pathways are potential drug targets. <h3>Conclusion</h3> Our analysis revealed a relationship between pathways involved in oxidative phosphorylation and poor prognosis and provides insight into potential drug targets.

Self-Perception Peculiarities of Adolescents at Risk of Getting into Residential Care
AbstractMitochondrial disorders are a heterogeneous group of often multisystemic and early fatal diseases, which are amongst the most common inherited human diseases. These disorders are caused by defects in the oxidative phosphorylation (OXPHOS) system, which comprises five multisubunit enzyme complexes encoded by both the nuclear and the mitochondrial genomes. Due to the multitude of proteins and intricacy of the processes required for a properly functioning OXPHOS system, identifying the genetic defect that underlies an OXPHOS deficiency is not an easy task, especially in the case of combined OXPHOS defects. In the present communication we give an extensive overview of the proteins and processes (in)directly involved in mitochondrial translation and the biogenesis of the OXPHOS system and their roles in combined OXPHOS deficiencies. This knowledge is important for further research into the genetic causes, with the ultimate goal to effectively prevent and cure these complex and often devastating disorders.
