Blue Native Polyacrylamide Gel Electrophoresis: A Powerful Diagnostic Tool for the Detection of Assembly Defects in the Enzyme Complexes of Oxidative Phosphorylation
Bibliographic record
Abstract
The bulk of ATP consumed by various cellular processes is normally produced by five multimeric protein complexes embedded within the inner mitochondrial membrane in a process known as oxidative phosphorylation (OXPHOS). Mutations that impair the assembly, and therefore the function, of one or more of these enzyme complexes severely compromise energy homeostasis and are a frequent cause of human disease. Because mitochondrial diseases are a clinically heterogeneous group of genetic disorders, biochemical and molecular diagnostic analyses are often an essential first step in confirming suspected cases and ultimately aid in identifying the genetic basis of disease in affected individuals. Blue native polyacrylamide gel electrophoresis has proven to be particularly invaluable in this regard, providing researchers with a facile approach for analyzing the assembly, total abundance, and residual enzymatic activity of individual OXPHOS complexes. As such, this technique has greatly facilitated the more thorough molecular genetic investigation of diseases that are caused by isolated and combined deficiencies in the enzymes that comprise the OXPHOS system.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
