We study the regulation and the activity of enzymes that remodel chromatin and how these enzymes promote normal tissue differentiation.
Discovering how cell differentiation is regulated is critical to understanding fundamental biology and to proposing new treatment methods for differentiation-centered diseases, including cancer.
We utilize molecular biology, biochemistry, and epigenetic experimental techniques to study mammalian SWI/SNF-mediated chromatin remodeling.
We are a friendly and collaborative team of researchers.

Muscle-specific pyruvate kinase isoforms, PKM1 and PKM2, regulate mammalian SWI/SNF proteins and histone 3 phosphorylation during myoblast differentiation
The Bromodomains of the mammalian SWI/SNF (mSWI/SNF) ATPases Brahma (BRM) and Brahma Related Gene 1 (BRG1) promote chromatin interaction and are critical for skeletal muscle differentiation.
Calcineurin Broadly Regulates the Initiation of Skeletal Muscle-Specific Gene Expression by Binding Target Promoters and Facilitating the Interaction of the SWI/SNF Chromatin Remodeling Enzyme
Opposing calcium-dependent signalling pathways control skeletal muscle differentiation by regulating a chromatin remodelling enzyme.
