Dr. Linda Luck

Professor of Biochemistry

My research laboratory is located in Hudson Annex at SUNY Plattsburgh and my goals are to understand how structure relates to function in biological molecules. In particular we are interested in studying how conformational changes that take place in proteins affect biological events such as the onset of breast cancer. In my laboratory we use proteins ranging from bacteria and human proteins including the estrogen receptor and androgen receptor. Recently we have developed biosensors from these proteins. My laboratory students use an array of methods spanning biophysics, biochemistry, protein engineering, and molecular biology. My students have access to modern tools of chemistry and biology including fluorescence, NMR, mass spectrometry, X-ray crystallography, electrochemistry, and molecular graphics.

 

Research

The Human Estrogen Receptor and Cancer

A present focus of my research is to explain the molecular basis for reproductive cancers especially breast cancer. Activation and control of the estrogen receptor play a critical role in both the development and progression of breast cancer. Transcriptional activation is thought to be stimulated via a ligand-dependent conformational change when ligands bind to the estrogen receptor. It is critical that we understand the molecular details of the interactions between the estrogen receptor and estradiol, antiestrogens and environmental estrogens. Although a crystal structure has provided us with a static picture of the hormone-binding domain of the estrogen receptor these data have not addressed the conformational changes that mediate the transcriptional events within the nucleus. We are investigating the use of NMR experiments to provide a greater understanding of how structurally diverse estrogens and antiestrogens interact with the estrogen receptor.

Biosensors for Endocrine Disruptors

Our laboratory is exploring the use of a Quartz Crystal Microbalance as a biosensor for the xenobiotic compounds that bind to the Estrogen and Androgen hormone receptors. One of the interesting and impending characteristics of the steroid receptors is their ability to tolerate large changes in ligand structure. A wide variety of diverse nonsteriodal compounds exhibit high affinity binding towards the steroid receptors, from such structural classes as pyrazole, stilbestrol, coumarin, isoflavones, and benzofurans. The behavior of compounds with respect to their steroid binding properties has proven difficult to predict because surprisingly, many bear no resemblance to endogenous steroids. Because such a diversity of compounds exhibit steroid behavior, and these compounds produce such dramatic and systemic effects, it is essential that we test new compounds before they are released into the environment where their effects on human and wildlife health could be enormous.
