DeCure for Combined oxidative phosphorylation deficiency 45
DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for combined oxidative phosphorylation deficiency 45 — 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 45 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 45 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.
What the evidence adds up to
Combined oxidative phosphorylation deficiency 45 is a mitochondrial disease, part of a group of inherited disorders caused by defects in the oxidative phosphorylation (OXPHOS) system. Mutations in almost 290 genes have been identified across mitochondrial diseases, but many patients still lack a molecular diagnosis. The OXPHOS system comprises five multisubunit enzyme complexes encoded by both nuclear and mitochondrial genomes, and combined OXPHOS defects involve multiple complexes. Identifying the genetic cause is difficult, especially for combined deficiencies, because of the large number of proteins and processes required for mitochondrial translation and OXPHOS biogenesis. Understanding how these defects lead to cellular dysfunction and organ pathology remains incomplete.
No clinical trial or case report specifically for combined oxidative phosphorylation deficiency 45 was found in the provided abstracts. One study on endometrial carcinomas found that TP53-inactive tumours with activation of oxidative phosphorylation had poor prognosis, and suggested PI3K/mTOR and autophagy pathways as potential drug targets. That study involved 85 patients and used gene expression profiling and pathway analysis, but it is not relevant to inherited mitochondrial disease. A 2010 review noted that combined OXPHOS deficiencies are often multisystemic and early fatal, and that further research into genetic causes is needed for prevention and cure. A 2017 review stated that shared pathogenic parameters influencing disease pathology offer promising avenues toward therapy development, but no specific drug or intervention was tested.
The abstracts contain no data on survival, response rates, or sample sizes for any treatment in combined oxidative phosphorylation deficiency 45. No drug is mentioned in connection with this disease. What is still missing is a molecular diagnosis for many patients, a complete understanding of how OXPHOS defects cause organ pathology, and any clinical trial testing a specific therapy for this condition. Patient stratification by genetic subtype and funding for functional studies of the underlying mechanisms are also lacking.

Mitochondrial energy generation disorders: genes, mechanisms, and clues to pathology
AbstractInherited disorders of oxidative phosphorylation cause the clinically and genetically heterogeneous diseases known as mitochondrial energy generation disorders, or mitochondrial diseases. Over the last three decades, mutations causing these disorders have been identified in almost 290 genes, but many patients still remain without a molecular diagnosis. Moreover, while our knowledge of the genetic causes is continually expanding, our understanding into how these defects lead to cellular dysfunction and organ pathology is still incomplete. Here, we review recent developments in disease gene discovery, functional characterization, and shared pathogenic parameters influencing disease pathology that offer promising avenues toward the development of effective therapies.

Mitochondrial Translation and Beyond: Processes Implicated in Combined Oxidative Phosphorylation Deficiencies
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.

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.
