Areas of Research Interest
The Gallo laboratory is interested in the understanding and therapeutic targeting of signaling pathways that govern cancer progression. In particular, we have focused on the mixed-lineage kinase (MLK) family and their roles in cancer invasion and metastasis, particularly in the context of breast cancer. We have demonstrated a critical role for MLK3 in triple-negative breast cancer metastasis in regulating both focal adhesion turnover during cell migration and gene expression during invasion and metastasis. In addition we are studying the roles of MLK family members and related signaling in lung cancer, glioblastoma, and melanoma.
Our laboratory uses diverse approaches and techniques to study mechanisms of tumor proliferation, invasion and metastatic outgrowth including 3D organotypic assays, cell biology, animal models, mass spectrometry, and biochemical techniques.
We collaborate with the Conrad lab (Microbiology & Molecular Genetics) in identifying mechanisms and alternative therapeutic strategies for endocrine resistant breast cancer. In collaboration with the Neubig lab in Pharmacology & Toxicology, we are exploring appropriate combination therapies in drug-resistant melanoma.
