Alika Maunakea, a Native Hawaiian epigeneticist, is investigating how epigenetic changes may explain accelerated aging in Native Hawaiian populations compared to other residents of Hawaii. His research focuses on how chemical modifications to DNA and proteins that regulate genes—without altering the genetic code itself—could drive health disparities.
Epigenetic markers reflect how environmental factors, stress, diet, and lifestyle trigger cells to activate or silence genes. These modifications accumulate over time and influence aging rates and disease susceptibility. Maunakea's work suggests epigenetic signatures could serve as early warning systems, identifying health risks decades before symptoms emerge clinically.
Native Hawaiians experience higher rates of obesity, type 2 diabetes, cardiovascular disease, and certain cancers compared to other Hawaii residents. Life expectancy gaps persist despite advances in medical care. Traditional explanations cite genetics and behavioral factors, but Maunakea argues epigenetics offers a more complete picture. Historical trauma, colonialism, food system disruption, and socioeconomic stress leave molecular imprints on cells that compound across generations and within individuals over time.
The research potential extends beyond diagnosis. Epigenetic changes are reversible. Unlike mutations locked into DNA, epigenetic modifications can shift with lifestyle interventions, stress reduction, or dietary changes. This plasticity offers therapeutic windows. Identifying high-risk individuals through epigenetic screening before disease manifests could enable targeted prevention programs tailored to Hawaiian communities.
Maunakea emphasizes that epigenetic research must center Indigenous perspectives and involve Native Hawaiian participation in study design and interpretation. He advocates moving beyond viewing Native Hawaiians as subjects of study toward genuine partnership in generating knowledge about their health.
The broader significance lies in how epigenetics reframes health disparities. Rather than attributing differences solely to genetics or individual behavior, epigenetic science reveals how social
