The impact of HMF on temperature stress resistance was particularly specific: it enhanced recovery from chill coma in control (GFP-RNAi) flies, while it accelerated recovery from heat shock in frataxin-silenced (fh-RNAi) flies. The mechanisms through which HMF modulate frataxin-associated phenotypes at a fundamental physical level warrant further investigation.

Hypomagnetic Fields Influence the Developmental Duration, Fecundity and Temperature Stress Resistance of Drosophila melanogaster via Frataxin-Associated Traits
Kang H, Wan G, Zhang J, Pan W. Hypomagnetic Fields Influence the Developmental Duration, Fecundity and Temperature Stress Resistance of Drosophila melanogaster via Frataxin-Associated Traits. Biology (Basel). 2026 Feb 27;15(5):391. doi: 10.3390/biology15050391. PMID: 41823819; PMCID: PMC12985338.
Arctigenin derivative (ARC-18) improved mitochondrial dysfunction and ameliorated frataxin deficiency symptoms via PGC-1α signaling
Gong Q, Han X, Liu T, Xiong B, Zhang B, Xie Y, Wan H, Ali T, Yang X, Li S. Arctigenin derivative (ARC-18) improved mitochondrial dysfunction and ameliorated frataxin deficiency symptoms via PGC-1α signaling. Genes Dis. 2025 Sep 1;13(4):101838. doi: 10.1016/j.gendis.2025.101838. PMID: 41884717; PMCID: PMC13011025.
Notably, co-treatment with the PGC-1α inhibitor SR-18292 abolished ARC-18 effects, confirming its dependence on PGC-1α activation to rescue mitochondrial deficits in FXN-deficient cells.
