Daniel Haber, MD, PhD
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

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

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
