  • Research

    The Dynlacht Lab has been interested in studying the effects of agents (physical or chemical) that modulate the response of cancer cells and normal tissue to the radiation response, particularly hyperthermia and various chemotherapeutic agents.  Hyperthermia has been shown to be effective in treating several types of tumors, but is often used most effectively when it is administered as an adjuvant to radiation therapy or chemotherapy, since heat sensitizes cells to radiation and some types of drugs (sensitization is believed to be mediated by an inhibition of repair of radiation- or drug-induced DNA damage). The current major focus of the Dynlacht Lab is to characterize novel chemotherapeutic agents that are not toxic at 37° C when given systemically, but which can become activated to become cytotoxic by local hyperthermia treatment, thereby potentially limiting lethal effects of the compounds solely to tumor cells within the heated tissue volume in patients. The Dynlacht group has also been studying the mechanism of heat-radiosensitization and the inhibition of repair of radiation-induced double strand breaks by hyperthermia. Two other unrelated objectives involve efforts to inhibit the formation of cataracts induced by therapeutic doses of radiation or doses of space radiation that astronauts would be expected to receive during interplanetary missions, and the development of non-pharmacological and pharmacological countermeasures against the lethal effects of radiation exposure from radiologic terrorist attacks (dirty bombs or improvised nuclear devices).
