Research Summary

The Haber laboratory focuses on understanding the fundamental genetics of human cancer, from inherited mutations that confer familial predisposition to genetic mutations that are acquired by tumors themselves and may render them susceptible to specific targeted drug therapies. For example, we have identified mutations in the EGFR gene that confer dramatic sensitivity of some lung cancers to drugs that inhibit that pathway, pointing toward the importance of genetic classification of common epithelial cancers in applying novel targeted therapies.

We have also collaborated with the bioengineering team led by Dr. Mehmet Toner, the molecular biology group of Dr. Shyamala Maheswaran, and the Massachusetts General Hospital Cancer Center clinical disease centers to develop, characterize and apply a microfluidic device capable of isolating rare circulating tumor cells (CTCs) in the blood of patients with cancer. This new technology offers the promise of 1) noninvasive monitoring of cancers during their treatment for the emergence of drug resistance; 2) early detection of invasive cancers; and ultimately 3) understanding and preventing blood-borne spread of cancer.

Research Projects

Our laboratory is interested in the genetics of human cancer. Current projects include the use of a microfluidic device to capture circulating tumor cells (CTCs) and its application in molecular-directed therapy and in the study of human cancer metastasis.

Circulating Tumor Cells and Molecular Genetics Underlying Targeted Cancer Therapeutics

Activating mutations in the epidermal growth factor receptor (EGFR) were identified in our laboratory in the subset of non-small cell lung cancer (NSCLC) with dramatic responses to the tyrosine kinase inhibitor gefitinib. We have studied mechanisms underlying such oncogene addiction, as well as the pathways that lead to the acquisition of resistance to targeted therapies, including the application of irreversible kinase inhibitors to circumventing mutations that alter drug binding affinity. Following on our efforts to monitor the emergence of drug resistance mutations, we are now collaborating with the Toner and Maheswaran laboratories to characterize novel microfluidic devices capable of isolating CTCs from the blood of cancer patients. Our most advanced version of these CTC-Chips relies upon blood flow through a specialized chamber, which allows the high efficiency separation of antibody-tagged leukocytes, thereby identifying intact CTCs without selection bias. In a series of CTC studies, we have shown that the number of captured CTCs correlates with clinical evidence of tumor response, and that the cells can be used to define molecular markers characteristic of the underlying malignancy, including EGFR mutations and EML4-ALK translocations in lung cancer, and measurements of androgen receptor (AR) activity in prostate cancer. We have applied next generation single-molecule RNA sequencing to identify non-canonical Wnt signaling as a suppressor of anoikis pathways in circulating pancreatic cancer cells, while in melanoma and in glioblastoma, we developed tools to isolate and molecularly characterize CTCs.

Our most recent studies have focused on breast cancer, where we demonstrated treatment-associated epithelial-to-mesenchymal transition (EMT) within CTCs. Using a combination of mouse models and patient-derived studies, we observed that tumor-derived fragments generate CTC-Clusters, which have greatly enhanced metastatic propensity compared with single CTCs. CTC-Clusters are held together by plakoglobin, whose knockdown dramatically suppresses CTC-Cluster formation and metastatic spread of breast cancer cells. We successfully established long-term in vitro cultures of CTCs from patients with estrogen-receptor positive breast cancer, identifying treatment-associated mutations in the estrogen receptor (ESR1), as well as acquired mutations in drugable therapeutic targets, such as PIK3CA and FGFR. The development of such CTC-derived cultures may enable functional predictive drug testing, combined with detailed genetic analysis of tumor cells sampled noninvasively during the course of cancer treatment.

Current efforts are directed at isolating single CTCs to uncover the heterogeneous nature of these rare metastatic precursors, including remarkable cell plasticity that contributes to drug resistance. Further technological improvements in CTC capture and detection are under study for potential applications in early detection of cancer, monitoring tumor genotypes over the course of treatment, and biological characterization of CTCs themselves.
