Are you climbing the corporate ladder, struggling to maintain your
social status, and experiencing lots of stress as a result? A new study
in monkeys suggests a link between improvement in social status and
changes in gene expression involved in immune response, suggesting a
change in social status may affect your health.
It’s well accepted that stress has an impact on both physical and
emotional health. Much research has linked stress levels with conditions
ranging from gastrointestinal disorders to depression, heart disease,
stroke, hair loss, and erectile dysfunction
.
Yoav Gilad, PhD, associate professor of human genetics at the
University of Chicago Biological Sciences, and his team studied social
ranking and stress among a population of 49 captive female rhesus
macaques of different social rank. They discovered that when a female
monkey’s social rank improved, her gene expression changed within a few
weeks, which suggests social influences or environment can alter genes.
According to Jennifer Tung, the postdoctoral researcher who led the
study, “There’s a spooky side to this kind of research, in that an
individual’s social rank is partially determining health status.” Gilad
also noted that the study results indicate “Whatever it is that causes
stress through social environment, you might be able to fix.”
