Abstract:
Dr. Stanbridge's research concerns the molecular genetics of human cancer. In addition to activated oncogenes, a family of genes (called tumor suppressor genes) critically involved in the control of malignancy has been identified. Dr. Stanbridge has provided functional evidence for the role of tumor suppressor genes in human cancer using somatic cell hybrid and monochromosome transfer techniques. His group has also engaged in cloning candidate tumor suppressor genes. One of the functions of such genes appears to be negative regulation of transcription of tumor-associated antigens. One such regulated gene has been identified as carbonic anhydrase 9 (CA9). The encoded protein, CAIX, is in clinical trials for diagnosis and therapy of multiple malignancies, including cervical cancer and renal cancer. CAIX has recently been found to be a marker of hypoxia. The mechanisms underlying this are under investigation.

An important question in the field of cancer molecular genetics is whether there are interactions between tumor suppressor genes and activated oncogenes. Ongoing studies in the laboratory addressing this question involve homologous recombination experiments that disrupt gene function.

Another research interest of Dr. Stanbridge's is to develop molecular probes for the identification of microorganisms in clinical settings. Dr. Stanbridge was one of the early developers of the use of cloned fragments of ribosomal RNA genes as molecular probes for detection of mycoplasmas and other microorganisms in idiopathic diseases such as rheumatoid arthritis where an infectious etiology is suspected.
