Welcome to the Palmer Lab at the University of Colorado Boulder!
Our research lies at the interface of chemistry and biology, where the application of chemical and physical principles provides a unique opportunity to better understand the fundamental biochemistry of living cells. Cells are complex entities that must integrate internal and external signals in order to coordinate diverse functions. Living cells are also dynamic, and this dynamism is key to understanding the mechanisms between cause and effect for biological processes. Deciphering the molecular details of how cellular constituents define healthy and diseased states, and how dynamics propagate from the cellular to the organismal level, is one of the great challenges in modern biology. Our lab develops new technologies to interrogate signaling cascades in cells to understand how the actions of specific proteins, molecules, and ions contribute to cellular function. We combine in vitro spectroscopic and biophysical techniques with protein design and engineering to develop novel fluorescent probes, and use long-term time-lapse fluorescence microscopy to elucidate the mechanisms of cellular signaling pathways. Longitudinal single-cell analyses also allow us to explore the origins and consequences of heterogeneity in biological systems. We are specifically interested in how cells regulate metal ions, how pathogens alter cell biology, and how to engineer improved photophysical properties in fluorescent proteins.

4/4/2010 – Microfluidic Cell Counter published – Dawn Schaefer (Colorado School of Mines) and Emily Gibson report a simple fabrication technique to create all silicon/glass microfluidic devices using femtosecond laser ablation and anodic bonding. In a first application, they constructed a cell counting device based on small angle light scattering. The counter featured embedded optical fibers for multi-angle excitation and detection of scattered light and/or fluorescence. The performance of the microfluidic counter was benchmarked against a commercial fluorescence-activated cell sorter.
4/1/2010 – Sub-Cellular Zinc (II) Dynamics published – In this publication, several new genetically encoded sensors for Zinc (II) are presented based upon fluorescence resonance energy transfer (FRET). Sources and sinks for Zinc (II) are explored within the cell, including the cytosol, plasma membrane, and mitochondria. Localized probes reveal that mitochondria contain an elevated pool of Zinc (II) under resting conditions that can be released into the cytosol upon glutamate stimulation of hippocampal neurons. Results suggests that mitochondria serve as a source of and a sink for Zinc (II) signals under different cellular conditions.
4/1/2010 – FACS-Based Selection of 3x ReAsH Motif published – Schuyler performed an in situ selection of a randomized amino acid linker library (10.2 million peptides) flanking three tandem optimized TC repeats.

In this study, Janet examined seven familial Alzheimer’s causing mutations in presenillin-1 to define how they influence ER calcium levels and dynamics. Ultimately, results indicate that mutations in presenillin-1 can alter the balance of calcium in cells and have the potential to influence the nature of calcium signals.
