Pancreatic tumor cells grow and invade during metastasis
Degradation of the extracellular matrix during metastasis is a necessary step in cancer progression. Here, a pancreatic cancer cell is degrading a fluorescent matrix (green) as it migrates. The dark areas represent the path of the cell.
Tumor Cell Growth and Migration
Cancers of the lung, pancreas and liver are listed as the first, third and fourth most lethal cancers in the United States and are increasing rapidly, according to the National Cancer Institute. The five-year survival rate for people with these tumors is exceptionally poor due to a lack of effective therapies that target the cells of these cancers, which tend to migrate away from the site of the primary tumor to invade distal organs. This metastatic behavior of tumor cells is the single most important factor affecting survival as 90% of mortality is due to metastatic invasion. It is regulated by hundreds of different cytoskeletal-membrane proteins.
The Membrane Trafficking in Disease Lab's research team seeks to understand how these tumor cells:
- Grow, multiply and dissociate from the primary tumor.
- Remodel the surrounding tumor stroma by protease secretion to escape into adjacent blood vessels.
- Support collective and independent migration to distal locations where they can form new tumors.
The lab's investigators (in collaboration with the Cell Biology of Metastasis Lab) explore how the metastatic behavior of tumor cells is regulated to discover new treatments for lung, liver and pancreatic cancers.
