Mitochondrial oxidative capacity and NAD+ biosynthesis are reduced in human sarcopenia across ethnicities
Open accessAbstract
The causes of impaired skeletal muscle mass and strength during aging are well-studied in healthy populations. Less is known on pathological age-related muscle wasting and weakness termed sarcopenia, which directly impacts physical autonomy and survival. Here, we compare genome-wide transcriptional changes of sarcopenia versus age-matched controls in muscle biopsies from 119 older men from Singapore, Hertfordshire UK and Jamaica. Individuals with sarcopenia reproducibly demonstrate a prominent transcriptional signature of mitochondrial bioenergetic dysfunction in skeletal muscle, with low PGC-1α/ERRα signalling, and downregulation of oxidative phosphorylation and mitochondrial proteostasis genes. These changes translate functionally into fewer mitochondria, reduced mitochondrial respiratory complex expression and activity, and low NAD + levels through perturbed NAD + biosynthesis and salvage in sarcopenic muscle. We provide an integrated molecular profile of human sarcopenia across ethnicities, demonstrating a fundamental role of altered mitochondrial metabolism in the pathological loss of skeletal muscle mass and function in older people.

TL;DR
In a multi-ethnic case-control study of muscle biopsies from older men, sarcopenia was reproducibly characterized by a dominant transcriptional signature of mitochondrial bioenergetic dysfunction, including low PGC-1α/ERRα signaling and downregulated oxidative phosphorylation and mitochondrial proteostasis genes. These changes translated into fewer mitochondria, reduced respiratory complex expression and activity, and 32% lower muscle NAD+ through perturbed NAD+ biosynthesis and salvage.
Key findings
- In the Singapore Sarcopenia Study (SSS), 179 genes were altered in sarcopenic muscle at FDR < 10% (133 downregulated, 46 upregulated), with 133 genes annotated to the mitochondrion GO term; oxidative phosphorylation, mitochondrial respiratory chain, and TCA cycle gene sets were repressed at FDR < 10E−10, and age-adjusted gene ranks were highly conserved (Spearman rs = 0.95).
- Mitochondrial dysfunction replicated across ethnicities: HSS and JSS showed lower oxidative phosphorylation, mitochondrial respiratory ETC, and TCA cycle gene sets at FDR < 10E−04 and 10%, respectively; low ALMi and low muscle function also associated with depleted mitochondrial gene sets.
- Functional validation showed NDUFA9, SDHa, UQCR2, and ATP5a protein levels down by 44–51%, lower complexes I–IV activity, strongly reduced citrate synthase and succinate dehydrogenase activity, and 32% lower muscle NAD+; NAD+ correlated positively with ALMi, grip strength, gait speed, and complex I activity, while NMNAT1 and NAMPT were reduced and CD38, PARPs, and sirtuins were not increased.
- Other signatures included repressed mTOR signaling (FDR = 1.2E−02) but less than OXPHOS; no denervation/NMJ or inflammatory signatures except weak inflammation in JSS; ALMi associated with 318 genes at FDR < 10%, whereas grip strength and gait speed associated with only 7 and 9 genes at nominal p < 0.001 but FDR > 10%.
Methods
- Multi-ethnic case-control MEMOSA study of 119 older men from Singapore (SSS), Hertfordshire UK (HSS), and Jamaica (JSS); SSS included 20 sarcopenic Chinese men and 20 age-matched controls, HSS included 40 Caucasian men, and JSS included 40 Afro-Caribbean men. Sarcopenia was defined by AWGSOP (SSS) or EWGSOP (HSS/JSS) criteria using ALMi, grip strength, and gait speed.
- Vastus lateralis muscle biopsies were profiled by high-coverage total RNA sequencing (>70 million reads per sample; SSS 75–104 million, HSS 51–110 million, JSS 55–88 million); differential expression used limma/edgeR, pathway enrichment used CAMERA with MSigDB, and selected genes were validated by nanoString nCounter.
- Functional assays included mitochondrial enzymatic activity on mitochondrial fractions from 15–30 mg muscle, western blot for respiratory complex subunits and mitochondrial proteins, and NAD+ quantification in remaining biopsies, benchmarked against UHPLC-MS.
Limitations
- Stated: NAD+ results require further validation because they were analyzed in a subset of SSS individuals with sufficient remaining muscle biopsy (Fig. 6b, n = 4–6 per group); complex IV western blot was detected in less than 20% of samples and was excluded from analysis.
- Stated/evident: the cross-sectional case-control design cannot establish causality, and all cohorts were older men, so findings may not generalize to women.
- Evident: functional validation sample sizes were small and varied by assay and cohort; replication cohorts had variable sample sizes per phenotype (e.g., NAD+ metabolic process gene-set analysis n = 4–28 per group), and no independent prospective validation is reported.

The Results sections report that mice lacking both Mfn1 and Mfn2 in skeletal muscle had smaller muscle fibers and reduced muscle size.

The Results section reports that Mfn2-deficient mice develop muscle atrophy and that Mfn2 deficiency promotes sarcopenia during aging. The paper describes OPA1’s role in mitochondrial fusion but does not report that loss of Opa1 causes sarcopenia. It also shows age-related sarcopenia is aggravated by Mfn2 loss, rather than establishing that Mfn2 loss alone is sufficient to cause sarcopenia. (LLM, conf=0.88)

The Introduction reports that muscle-specific Opa1 deletion causes muscle loss, and the Discussion reports reduced muscle mass after combined Mfn1/Mfn2 deletion. The paper does not establish that loss of Mfn2 alone causes sarcopenia in mice; its mitofusin comparison concerns deletion of both genes. No page numbers are available in our copy. (LLM, conf=0.86)

Little is known about the molecular processes of pathological sarcopenia compared with healthy muscle aging.
“While the molecular processes associated with the average functional decline of muscle in the healthy population have been well studied, little is known about the pathological state of sarcopenia, the pathological muscle wasting and weakness of the old age recently assigned an ICD-10 disease code due to its negative impact on physical function, quality of life, and survival6,19–21.”
The paper relies on this without support.
The clinical definition of sarcopenia is standardized enough to characterize a molecular signature of sarcopenia in older people.
“Standardization of the clinical definition now provides an opportunity to characterize the molecular “signature” of sarcopenia in older people.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
