Summary

The Wu laboratory is interested in using chemical biology and functional genomics approaches to study lipid biology, developmental signaling networks and cellular processes in normal physiology and diseases.

We focus on studying developmental signaling pathways, such as Wnt, Hedgehog, Hippo and JAK-STAT signaling, and aim to discover novel chemical modulators of stem cell fate and cancers. In addition, we develop and utilize chemical probes to study protein fatty acylation (myristoylation, palmitoylation, stearoylation etc.), and to identify novel enzymes or enzyme-like activities involved in dynamic regulation of protein lipidations (fatty acyltransferases and deacylases). We aim to reveal the functions of protein lipidation, and to understand how deregulation of lipid metabolism leads to diseases.

The specific research projects in our lab include:

  1. Chemical approaches to study posttranslational protein lipidation and lipid metabolism in cellular processes

  2. Chemical approaches to dissect signal cross-talking and “rewiring” in degenerative diseases and cancers

  3. Chemical and functional genomic approaches to explore cellular senescence and terminal differentiation
