The purpose of this group is to determine aspects of HER2 signaling in HER2 amplified cancer cells that can serve as the basis for near-term publications. New data demonstrates how the tumor microenvironment has subtype-specific effects on cancer cells that have the capacity to rewire internal signaling, and cause anti-HER2 therapeutics to become growth stimulants. This potentially involves: novel heterodimers, RTK feedback loops, overexpression of exogenous growth factors, intercellular trafficking, and morphological changes.
The preliminary figure below illustrates some proposed mechanisms in luminal HER2+ cell lines for how lapatinib treatment can result in enhanced growth when there are high levels of exogenous NRG1.
