Animal and plant cells typically exist in physiologically controlled environments that are always nutrient-rich, yet they proliferate selectively. This is because specific signals from other cells stimulate or limit their growth and proliferation according to rules that benefit the organism as a whole. The goal of Dr. Edgar’s lab is to understand some of the genetic logic – or regulatory “circuitry” - that controls cell growth and coordinates it with cell cycle progression in vivo, in the Drosophila model system.
They aim to define new genes and regulatory pathways involved in growth control that will impact general paradigms in cell and developmental biology, and which may also have relevance to topics in human health such as cancer biology, stem cell therapy, and metabolic disease.
Current topics of their interest include: Cell cycle exit at differentiation, Endocycle control, TOR signaling, and Intestinal stem cell regulation.
