Project title: The Role of Klotho and Foxo in Pathological Remodeling of the Heart.
Human subjects IRB approved project number (where applicable): N/A
Animal subjects IRB approved project number (where applicable): N/A

Brief Description of Project:
Foxo proteins are members of the Forkhead family of transcription factors and
have been implicated in many physiological functions including stress responses,
cell-cycle progression, apoptosis and longevity. We have found recently that
Foxo transcription factors counter hypertrophic growth through inhibition of
calcineurin activity. Recently, it has been reported that an anti-aging hormone,
Klotho, activates Foxo protein in HeLa cells. We are interested in dissecting
possible contribution of Foxo to the lifespan-extending properties of Klotho.
Students who participating in this summer project will help to answer two specific
1. Does Klotho activate Foxo in cardiac myocytes?
2. Does Klotho treatment increases resistance to oxidative stress in cardiac myocytes
Students will have opportunities to conduct hands-on experiments using a variety of molecular and cellular techniques, forming and refining hypothesis, and presenting in weekly lab meetings.
Previous Research Activities or Publications with Medical Students:
I supervised an undergraduate student, David Morris, from the Austin College last summer. He is a co-author of a manuscript we submitted recently to the journal Circulation.
