Research Interests

We are investigating how development is controlled in the fourth dimension. Animals posses explicit genetic regulatory mechanisms that control the timing and synchrony of developmental events. Interestingly, the molecules involved are unlike other developmental patterning regulators and often involve post-transcriptional gene regulation. Most prominent among these unusual regulators are the microRNAs which were discovered in the developmental timing pathway of the nematode C. elegans. We are combining biochemistry, molecular biology and genetics to dissect and explore the developmental timing mechanism.

We discovered that Lin-28, an RNA-binding protein and a key developmental timing regulator of C. elegans, is conserved from worms to humans. It appears to be a timing regulator in many developmental events in the mouse and to be regulated by microRNAs through its 3' untranslated region. We are using the power of mouse molecular and developmental biology to extend our understanding of timing from worms to mice and humans.
