Vanhenemiskokeita

Vanhenemiskokeita is a Finnish term used to describe experiments aimed at understanding aging processes and testing interventions intended to influence them. In gerontology, the term covers studies that seek to uncover the biological mechanisms of aging, identify biomarkers of aging, and assess approaches that might extend healthspan or lifespan.

The word combines vanheneminen, meaning aging, with koe, meaning test, in the plural form vanhenemiskokeita. The term is used primarily in Finnish-language scientific literature to refer to experiments rather than observational studies alone.

Vanhenemiskokeita are conducted in a range of systems, from yeast and nematodes to mice, rats, and human cell cultures. They include interventional trials, controlled laboratory experiments, and, in humans, longitudinal observational studies alongside randomized trials. Endpoints commonly include lifespan, healthspan measures such as mobility and metabolic function, and molecular biomarkers like epigenetic clocks and inflammatory indicators.

Common approaches involve caloric restriction, pharmacological agents, and other interventions tested in model organisms, as well as genetic and metabolic strategies in experimental settings. The field distinguishes between basic discovery studies and translational efforts aiming to apply findings to humans, with varying degrees of success across species.

Ethical and regulatory considerations accompany vanhenemiskokeita involving humans and animals. Human studies require informed consent and oversight by ethics committees and regulators; animal work follows welfare guidelines and the 3Rs principle to minimize suffering and improve welfare.

The modern field of aging research broadened in the late 20th century with the emergence of geroscience, and gains in translational potential occurred in the 2000s and 2010s, though translation from animals to humans remains challenging. See also aging, gerontology, longevity research.
