Research in the Ahmed Lab:

Wnt Signaling in Development and Disease

Our lab focuses on the mechanisms that control Wnt signal transduction, a cell-cell communication pathway that is critical for animal development and for stem cell maintenance in adult organs. Deregulation of Wnt signaling is associated with many human diseases, including nearly all colorectal cancers. We use genetics, biochemistry, and cell biology approaches to focus on these major unsolved questions:

1. How is the Wnt receptor complex assembled and activated?

2. How are the negative regulators of the pathway inhibited when Wnt is present?

3. What nuclear proteins control Wnt-dependent target gene activation?

Our long-term goal is to elucidate the mechanisms that control Wnt signaling during development and to use this knowledge to identify control points in the pathway susceptible to therapeutic targeting in Wnt-driven diseases.

Rotation projects will focus on new components in the Wnt signal transduction pathway with therapeutic potential that we have recently identified through genome-wide screens.

Graduate student rotations and postdoc applications are encouraged.
