9.      Cancer cell Metabolism and Tumor Microenvironment

Key discoveries have been the identification of Integrin-mediated signaling pathways leading to regulation of cell proliferation, survival and migration. The discovery of Integrin-Linked Kinase (ILK) in 1996 in the Dedhar laboratory has demonstrated how integrin receptors on different types of cells coordinate signals to regulate cellular homeostasis. ILK is required for embryonic development, for the formation of blood vessels and for cardiac function. It is also essential for the regulation of the proper development of neurons as well as the function of other cell types such as chondrocytes, smooth muscle cells, skin cells and hair follicle cells.

ILK was found to induce oncogenic transformation of epithelial cells and subsequently has been shown to be expressed at abnormally high levels in many types of human cancers. In many cases the amount of ILK protein in cells predicts for long term patient survival, i.e. the higher the amount, the worse the prognosis, suggesting that ILK contributes to the disease process and to therapeutic resistance.

ILK activation promotes the survival and growth of tumor cells and also promotes the HIF-1 and VEGF mediated angiogenesis

Recent work using sophisticated Proteomics technology has revealed that ILK localizes to the centrosome, in addition of focal adhesions where integrins are present. In the centrosome ILK controls the assembly of the mitotic spindle during cell division. It also regulates the clustering of supernumerary centrosomes that exist in many cancer cells. The clustering of centrosomes in cancer cells allows them to survive and divide normally. Blocking the function of ILK in centrosomes in such cancer cells results in centrosome “declustering” and cell death. Therefore blocking ILK can induce the death of cancer cells but not of normal cells which o not require centrosome clustering.


ILK is a Cancer Therapeutic Target.

Inhibition of ILK activity suppresses tumor growth and progression to metastasis, and compounds that inhibit ILK activity are under development. Inhibitors developed so far appear to selectively kill tumor cells relative to “normal” counterparts. Collaborative research has shown that ILK inhibitors could be used therapeutically for breast cancer, prostate cancer, pancreatic cancer, colon cancer, non small cell lung cancer, malignant melanoma, glioblastoma, acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML)


Models of Cancer Metastasis, Hypoxia and Carbonic Anhydrases IX and XII

Patient mortality results from the formation of metastases in distant (vital) organs. The metastatic potential of primary tumors is variable and likely depends of the biology of the tumor. We have established mouse models to study metastasis. Our initial work with breast cancer models of metastasis has identified a gene signature that is unique to metastatic tumors. Many of the genes are induced by “hypoxia” and function to protect the cells and promote survival in a hypoxic environment. Two of the genes CAIX and CAXII regulate the pH of the cells in hypoxia, and we have discovered that blocking the function of CAIX results in the death of the metastatic cells in a hypoxic environment, and in tumor regression as well as formation of metastasis.

Examination of the expression of CAIX in about 4000 breast cancer samples demonstrated that CAIX expression predicts for poor patient prognosis as well as for the formation of distant metastasis. Current work is focused on determining how CAIX controls the survival of hypoxic tumor cells and why it is needed for the formation of metastases. We are also developing compounds that could be used therapeutically to block CAIX function and also to image CAIX and identify hypoxic and potentially metastatic tumors.
