Effects of exercise training on oxidative phosphorylation-related genes in a diabetic heart via microarray analysis.
Article in BMC cardiovascular disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDiabetic heart disease is marked by structural, functional, and molecular alterations in the myocardium. We investigated the effects of exercise training on oxidative phosphorylation-related genes in the diabetic heart.
methodsMale mice C57BL/6JNarl (n = 24) were randomly divided into three equal groups: STZ-induced diabetic group with 12-week exercise training (DM-EX); diabetic group (DM); a non-diabetic control group. After completion of exercise training, samples from the soleus and heart tissues were collected from all the mice. Out of eight mouse samples from the DM and DM-EX, two left ventricles from either group were randomly selected and processed for RNA extraction and microarray analysis.
resultsExercise training changed the expression of 517 genes (P < 0.05); 380 upregulated,137 downregulated. Enrichment analysis depicted that apoptosis, diabetic cardiomyopathy, and oxidative phosphorylation were most significantly regulated. Pathway analysis revealed that exercise training upregulated 17 key oxidative phosphorylation genes, including complex I (Ndufa13, Ndufb4, Ndufb8, Ndufb9, Ndufc1, Ndufc2, Ndufs4, Ndufv2), complex III (Uqcrfs1, Uqcrh), complex IV (Cox5A, Cox7A, Cox17), and complex V (Atp5e, Atp5g3, Atp5k, Atp5l).
conclusionExercise training amplifies the gene expression concerned with oxidative phosphorylation in the diabetic heart, showing its potential to modulate molecular pathways that influence cardiac functions and improve the diabetic heart. CLINICAL TRIAL NUMBER: Not applicable.
