Luteolin in fruit flies: adult female benefits, embryonic lifespan harm
In Drosophila, luteolin given to adult females was linked to an 11.6% higher median lifespan and better movement and stress resistance, while embryonic exposure shortened lifespan; males responded little. These are fly findings, not human outcomes. [1]
Automatic summary · not editorially reviewed
The key findings
Fruit flies were exposed to luteolin either during adulthood or during embryonic development, then assessed for lifespan, healthspan, metabolic regulation and aging-related molecular changes. [1]
Adult supplementation increased median lifespan by 11.6% and improved locomotor activity and stress resistance, with pronounced female-specific benefits and little response in males. [1]
Embryonic exposure shortened lifespan and disrupted endocrine and metabolic homeostasis, with elevated juvenile hormone levels, reduced catalase activity and dysregulated IIS signaling. [1]

Luteolin timing and sex in fruit flies
The study exposed Drosophila melanogaster to the dietary flavonoid luteolin either during adulthood or during embryonic development. It then assessed lifespan, healthspan, metabolic regulation and aging-related molecular changes. The authors state that effects of luteolin on physiological aging, and the role of developmental stage and biological sex, were previously poorly understood.

Female-specific adult benefits in the abstract
Adult supplementation showed pronounced benefits specific to females: median lifespan rose by 11.6%, locomotor activity and stress resistance improved, and body weight changed little. Males showed little response. Short-term supplementation in early adulthood was reported to produce sustained protective effects later in life. Mechanistically, the abstract lists enhanced antioxidant defenses, suppressed IIS/PI3K-mTOR signaling, activated AMPK/MAPK pathways, promoted autophagy and immune homeostasis, and metabolic remodeling with reduced mitochondrial stress and favorable histone modifications.

Embryonic exposure shortened lifespan in the abstract
In contrast, embryonic exposure shortened lifespan and disrupted endocrine and metabolic homeostasis, with elevated juvenile hormone levels, reduced catalase activity and dysregulated IIS signaling. The authors conclude that luteolin's effects on aging in Drosophila depend strongly on developmental stage and biological sex, and that developmental exposure produced adverse outcomes.

How to interpret this
This is an abstract; the full text was not reviewed. All findings come from Drosophila melanogaster, not humans, and describe associations and proposed mechanisms rather than proven causes or human lifespan benefits.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
