Profile Headshot

Overview

Gerard Karsenty M.D., Ph.D., is the Paul A. Marks M.D., Professor and Chair of the Department of Genetics and Development at Columbia University Medical center, New York City. In the last 20 years, his laboratory has studied every aspect of skeletal biology ranging from development to physiology. His laboratory deciphered the molecular bases of osteoblast-specific gene expression, a work that culminated in his identification of Runx2 as the master gene of osteoblast differentiation. This was followed by the identification of an entire cascade of transcription factors regulating osteoblast differentiation and of Gcm2 as the master gene of parathyroid gland development. In approaching bone physiology Karsenty proposed that there is a coordinated control endocrine in nature, of bone mass, energy metabolism and fertility. The Karsenty lab has verified in the mouse and whenever possible in humans all tenets of this hypothesis. One of them is that bone should be an endocrine organ regulating energy metabolism and reproduction. This led to the identification of osteocalcin as a bone-derived hormone needed for insulin secretion, glucose homeostasis, testosterone secretion by Leydig cells of the testes and male fertility, brain development cognition and adaptation to exercise. Currently his work focuses through the definition of all functions of osteocalcin in understanding why would bone be an endocrine organ.

Grants

5P01AG032959-13 (PI: Karsenty)
9/2020 – 5/2025
NIH / NIA (Project 1 and Admin Core)
Bone as a sensor of and responder to stress during aging
This application aims at exploring the relationship between bone and stress response and using this knowledge to combat manifestations of aging. The goal of Project 1 is to determine whether the regulation of the release of osteocalcin can be harnessed to prevent or rescue manifestations of aging. The major goal of the Admin Core is to provide administrative support to the Program Project.

5R01DE027887-05 (PI: Karsenty)
8/2018 – 7/2023
NIH/NIDCR
A neuronal basis for the osteocalcin regulation of bone mass.
The major goal is to determine whether the inactivation of Gpr158 in the locus coeruleus will result in a high bone mass by decreasing the sympathetic tone.
Primary Place of Performance: Columbia University Irving Medical Center, New York, NY

5R01AR073180-04 (PI: Karsenty)
4/2019 – 2/2024
NIH/NIAMS
Muscle regulation of bone function.
The goals of this proposal are to determine 1) whether interleukin-6 (IL-6) regulates adaptation to exercise by signaling in bone cells and 2) IL-6 regulates bone mass specifically during exercise.
Primary Place of Performance: Columbia University Irving Medical Center, New York, NY
