Research Interests

The Means laboratory is interested in the study of cell signaling cascades that regulate cell proliferation, differentiation or function and how alterations in these pathways contribute to development of cancer and other diseases such as obesity. It is hoped that an understanding of these pathways may provide clues to novel targets that may be amenable to drug discovery.

The current primary focus of the research effort is to investigate the cellular and genetic mechanisms that govern regulation of the CaM kinase cascade. We explore cell surface receptor-mediated systems that elevate intracellular calcium, activate CaM and initiate pathways involving members of the CaM kinase cascade leading to events that alter cell fate and/or function. The proteins involved in these cascades are the upstream kinases CaMKK1 and CaMKK2 and the downstream kinases CaMKI, CaMKIV and AMPK. Examples of such projects now under study are how CaMKK2 and its downstream kinase targets regulate stem cells, energy expenditure, metabolism and inflammation.
