Dr. Beitz's laboratory has several lines of ongoing research. One of the current projects focuses on identifying factors secreted by tumors that cause cancer pain in animals and humans (the neurochemical and molecular basis of cancer pain). His laboratory has been involved with developing several animal models of cancer pain. We are also interested in the mechanisms underlying tumor metastasis focusing on bone metastasis and metastasis of pancreatic tumors. Microperfusion studies are underway to identify the substances secreted by tumors. Once the substances are identified tumor cells are transfected with siRNA constructs to knockdown these substances in order to determine the role they play in tumor-induced pain and/or tumor metastasis. A second major research project in the lab focuses on investigating the basis for gender differences observed in certain pain syndromes. A number of pain syndromes are more common in females than males and this project attempts to elucidate the mechanisms responsible for these sex differences. We are also investigating the mechanisms that underlie the development of pain in a mouse model of multiple sclerosis. Finally, work is being done to determine the neural mechanisms responsible for acupuncture’s analgesic and anti-inflammatory effects.
