The following projects are currently ongoing in the Brodt lab (please see detailed description below):
1. Sex disparity and the role of estrogen in the microenvironment of liver metastases
2. Optimizing delivery of the IGF-Trap to the brain for the treatment of glioblastoma
3. Combinatorial immunotherapy for pancreatic ductal adenocarcinoma
4. The role of IMP1 in pancreatic ductal adenocarcinoma progression and liver metastasis.
Our research has focused on the biology of cancer metastasis. In this context, our work has centered on the role of the microenvironment (ME) in liver metastasis (LM) of GI and lung cancer. Our overarching goal has been translational with an aim to identify targets and develop therapeutic interventions to block the spread of malignant disease to, and within the liver. In the course of these studies, our research team was among the first to show that cancer cells entering the liver induce a rapid inflammatory response, resulting in a cytokine cascade that enables trans-endothelial migration and liver colonization. We showed that in this TNF-飦� rich ME, the metastatic cells escape death through autocrine IL-6/STAT3 signaling while the TNF receptor TNFR2 was identified as a survival factor for regulatory T cells (Treg) and myeloid derived suppressor cells (MDSC) in the immune-tolerant ME (IME) of LM. Our team was also among the first to document the importance of the IGF axis to cancer cell invasion and metastasis in general, and LM, in particular. Several strategies for targeting the IGF axis were developed, leading to the bioengineering of the IGF-Trap - a potent inhibitor of growth and metastasis of several aggressive cancers including colon cancer, lung cancer and pancreatic ductal adenocarcinoma (PDAC). More recently, we found that the IGF-Trap affects the innate immune response to metastatic cells in the liver. Our work on PDAC also led us to identify a novel interaction between the pancreatic and hepatic stellate cells that leads to the formation of pre-metastatic niches in the liver, thereby promoting PDAC liver metastasis. More recently, we have begun testing the therapeutic effect of the IGF-Trap in orthotopic models of glioma using novel strategies for overcoming the brain blood barrier and effectively delivering this drug to the brain.
