Signal Transduction
The Signal Transduction Program explores the molecular signals within and between cells that drive cancer. These researchers are developing innovative new models for human tumors and advanced imaging technology with a goal of identifying potential “druggable” targets and mechanisms of drug resistance in cancer. Current research is focused on identifying and targeting the signaling mechanisms and tumor-host interactions that drive cancer.
Program Co-leaders
The Signal Transduction Program has two major overarching themes: 1) Identifying and targeting signaling in cancer; and 2) Characterizing and attacking tumor-host interactions driving cancer. In addition, the Signal Transduction Program is working to develop improved models of cancer. Program members include experts who bring an in-depth understanding of different families of signaling proteins, integrated with investigators who have expertise in cutting-edge technologies and systems. As such, the program generates basic discoveries that can drive the development of new cancer therapies.
Extensive collaborations among Signal Transduction Program members and other CSHL Cancer Center Programs have combined novel model systems of cancer, RNA interference, CRISPR, and state-of-the-art molecular/cellular and biochemical/proteomics approaches. Most Signal Transduction Program members also have clinical collaborators, predominately with investigators at Northwell Health. This highly collaborative and innovative environment has led to breakthroughs in our understanding of the signaling networks and immune interactions that drive cancer.

Semir Beyaz
Are you really what you eat? Our goal is to uncover the precise mechanisms that link nutrition to organismal health and disease states at the cellular and molecular level. A particular focus in our lab is to understand how dietary perturbations affect the immune system and contribute to the risk of diseases that are associated with immune dysfunction such as cancer.

Mikala Egeblad
Cancer cells are surrounded by immune cells, blood vessels, chemical signals and a support matrix—collectively, the tumor microenvironment. Most microenvironments help tumors grow and metastasize, but some can restrict tumors. My lab studies how to target the bad microenvironments and support the good ones to combat cancer.

Douglas Fearon
I’m studying how to harness the power of the immune system to fight cancer. Our underlying premise is that the microenvironment within a tumor suppresses the immune system. We have found a way to eliminate this suppression in the mouse model of pancreatic cancer, which has led to development of a drug for human pancreatic cancer that will enter phase 1 clinical trials in 2015.

Tobias Janowitz
Cancer is a systemic disease. Using both laboratory and clinical research, my group investigates the connections between metabolism, endocrinology, and immunology to discover how the body’s response to a tumor can be used to improve treatment for patients with cancer.

Darryl Pappin
Our genome can encode hundreds of thousands of different proteins, the molecular machines that do the work that is the basis of life. I use proteomics, a combination of protein chemistry, mass spectrometry and informatics, to identify precisely which proteins are present in cells - cells from different tissues, developmental stages, and disease states.

Ullas Pedmale
Unlike animals, plants neither have specific organs that see or hear various stimuli, yet, plants are sensitive to their surrounding environment and modify their development according to various external signals. My lab studies how the environment of a plant modulates its growth and development. Understanding environmental control of growth will have far-reaching implications for agriculture, energy production, and many other human activities.

Nicholas Tonks
Cells must constantly react to what is happening around them, adapting to changes in neighboring cells or the environment. I study the signals that cells use to exchange information with their surroundings. Our group is finding drugs that target these signals and thus can treat diabetes, obesity, cancer, and autism spectrum disorders.

Lloyd Trotman
We have recently developed the first genetic mouse model for therapy and analysis of metastatic prostate cancer. Now we can test if and how modern concepts of cancer evolution can outperform the 80-year-old standard of care - hormone deprivation therapy - and turn lethal prostate cancer into a curable disease.

David Tuveson
Pancreatic cancer is an extremely lethal malignancy. On average, patients who are diagnosed with pancreatic cancer succumb to the disease within 6 months. Research is the only way to defeat pancreatic cancer. My lab is making progress toward finding a cure by detecting the disease earlier and designing novel therapeutic approaches.

Linda Van Aelst
Normal cell function relies on coordinated communication between all the different parts of the cell. These communication signals control what a cell does, what shape it takes, and how it interacts with other cells. I study these signaling networks to understand how they guard against cancer and neurological disorders.
