Molecular Cell Biology & Cancer Research Group
Knowing the components of cells and how cells work is fundamental to all biological sciences. There are similarities and differences between cell types, which is particularly important to the fields of cell and molecular biology as well as to biomedical fields such as cancer research and developmental biology. These fundamental similarities and differences can permit the principles learned from studying one cell type to be extrapolated to other cell types. Thus, research in cell biology is closely related to genetics, biochemistry, molecular biology, Immunology and developmental biology.
Oncogenically transformed cells arise through a multistep process, and are normally subject to immune surveillance and elimination by the immune system. Several hereditary factors can increase the chance of cancer-causing mutations, including the activation of oncogenes or the inhibition of tumor suppressor genes. Various oncogenes and tumor suppressor genes can be disrupted at different stages of tumor progression, and mutations in such genes can be used to classify the malignancy of a tumor. The identification of oncogenes and tumor suppressor genes is important to understand tumor progression and treatment success. Much of the research done by this group is focused on understanding the immune mechanisms involved in tumor recognition and rejection, as well as fundamental mechanisms of cellular transformation. Studies include translational research aimed at improving cancer therapeutics and/or cancer vaccines.
