Researchers from the Houseknecht laboratory at the SWAG视频 College of Osteopathic Medicine participated in the annual Costas T. Lambrew Maine Medical Center Research Retreat on May 2, 2017 at Maine Medical Center in Portland. 

The lab, run by Karen Houseknecht, Ph.D., focuses on the regulation of mood and metabolism and specifically the role of psychiatric medications in modulating metabolic status.

Megan Beauchemin, Ph.D., Post-doctoral fellow in the laboratory, presented a poster titled, 鈥淎cute treatment with the antipsychotic drug, risperidone, alters brain activity and circadian rhythms in the heart.鈥  The poster was awarded second place in the Basic Science category for scientific presentations. This work shows for the first time that antipsychotic medications activate areas in the brain associated with regulation of circadian function and also alter the expression of circadian genes in the heart. 

Houseknecht, senior author on the work, proposes that these data suggest that antipsychotic medications, which are widely prescribed off-label to vulnerable populations including children, may cause early effects on cardiac function that have been previously undetected.

Collaborators on this work include Katie Motyl, Ph.D., and Anyonya Guntur, Ph.D., of the Department of Molecular Medicine at Maine Medical Center Research Institute; Deborah Barlow, Ph.D., technician in the Houseknecht lab; Celeste Bouchard (SWAG视频 COM 2020) and Peter Caradonna of the Histology and Imaging Core in the SWAG视频 Center of Biomedical Research Excellence for the Study of Pain and Sensory Function (COBRE).
