Oral cancer in the crosshairs at San Antonio Dental School
Source: tpr.org Author: Wendy Rigby San Antonio researchers are working on a new therapy for a stealthy killer: oral cancer. Visits to the dentist are your number one protection against the disease. In a lab at the University of Texas Health Science Center at San Antonio, dental researcher Cara Gonzales, DDS, Ph.D., shared promising news on a new approach to healing. "It was very exciting," Gonzales said. "These patients have not had any new therapeutic options in 40 years." The discovery of a new gene that’s turned on in oral cancers gave Gonzales and her colleagues a new target at which to aim. It’s a gene that’s also found in lung cancers. So-called nude mice are used in the oral cancer experiments. Wendy Rigby / Texas Public Radio Gonzales works in a sprawling space filled with lab equipment and cell lines used in many molecular biology projects. One of her research assistants brought in a cage of lab animals with some strange lumps on their backs. "These are called nude mice because they don’t have a complete immune system," Gonzales explained. These mice are at the center of a successful experiment. First, scientists used human oral cancer cells to grow large tumors on the animals. They tried one oral cancer drug already on the market. Not much action. Then, they tried a lung cancer drug, also already approved by the Food and Drug Administration. Not that effective on its own. Finally, they used a combination of two drugs. [...]
