Research Interests: Physiological,
biochemical, molecular and genetic adaptations
to altered usage of skeletal muscle.
Dr. Booth is interested in the determining
how exercise signals are sensed, transduced,
and effect the expression of genes in skeletal
muscle. To this end, multiple animal models
of exercise and physical inactivity are
employed. The end point of such investigations
is to provide on the molecular level of
evidence-based medicine for why sedentary
lifestyle increases the risk of many unhealthy
conditions. Skeletal muscle affects the
health of other organs (heart, adipose tissue,
brain, etc.) by altering insulin resistance,
blood hypertriglycidemia, blood HDL levels,
and neuro-integrative pathways. Thus, all
molecular events to decreased contractile
activity must be integrated into models
of how inactive skeletal muscle diminishes
the expression of putative "health"
genes.
