Effects of Binge Alcohol Exposure
on Skeletal Biology
My research is focused on the biochemical, biomechanical
and molecular effects of alcohol on the skeleton. Previous
studies performed in my laboratory using a binge model of
alcohol consumption, identified that bone resorptive activity
increases after acute binge alcohol exposure, which is at
least partially responsible for bone loss observed after binge
alcohol treatment. Alcohol-induced bone loss can be
effectively blocked with anti-resorptive drugs, suggesting a
possible therapeutic response to alcoholic osteopenia. We have
also shown that binge alcohol exposure has an additive effect
on bone loss caused by other insults to the skeleton such as
ovariectomy-induced estrogen depletion. My current research
effort is focused on identifying biomarkers of early
alcohol-mediated bone damage in adolescent and adult
ovariecotomized subjects using gene expression array
technology. Gene expression profiles of alcohol-induced bone
damage will help in the identification of novel mechanisms
behind bone damage caused by alcohol. Early markers of bone
loss can be used to identify patients at risk for osteoporosis
years prior to conventional diagnostics. Anti-resorptive drugs
may modulate the expression of genes perturbed by
alcohol-exposure; identification of biomarkers that
demonstrate this effect will be useful in monitoring the
efficacy of bone-sparing drugs, development of novel
therapeutics for osteoporosis and for identifying the
mechanisms responsible for alcohol-related osteopenia.
