What We Talk About When We Talk About Evolution.

Cell Commun Insights 2015;7:1-15

Harbor-UCLA Medical Center, West Carson Street, Torrance CA.

Currently, the biologic sciences are a Tower of Babel, having become so highly specialized that one discipline cannot effectively communicate with another. A mechanism for evolution that integrates development and physiologic homeostasis phylogenetically has been identified-cell-cell interactions. By reducing this process to ligand-receptor interactions and their intermediate down-stream signaling partners, it is possible, for example, to envision the functional homologies between such seemingly disparate structures and functions as the lung alveolus and kidney glomerulus, the skin and brain, or the skin and lung.

Identification of Signaling Protein Complexes by Parallel Affinity Precipitation Coupled with Mass Spectrometry.

Cell Commun Insights 2013 Sep;5:1-7

Burnett School of Biomedical Science, College of Medicine, University of Central Florida, Orlando, FL, USA.

Protein-protein interactions play a pivotal role in both inter- and intra-cellular signaling. Identification of signaling protein complexes can thus shed important new insights into cell communications. We developed a parallel affinity precipitation protocol to overcome the disadvantages of the tandem affinity purification procedure, such as the potential disruption of target protein conformation, subcellular localization or function by epitope tags, the potential need of large amounts of cell culture or generation of stable cell lines, and relatively long duration the two-step precipitation takes.

The Evolution of Cell Communication: The Road not Taken.

Cell Commun Insights 2009 Sep;2:17-25

Department of Pediatrics, Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center, Torrance, California, U.S.

In the post-genomic era the complex problem of evolutionary biology can be tackled from the top-down, the bottom-up, or from the middle-out. Given the emergent and contingent nature of this process, we have chosen to take the latter approach, both as a mechanistic link to developmental biology and as a rational means of identifying signaling mechanisms based on their functional genomic significance. Using this approach, we have been able to configure a working model for lung evolution by reverse-engineering lung surfactant from the mammalian lung to the swim bladder of fish. Read More

TGF-β1-Induced Expression of the Anti-Apoptotic PAI-1 Protein Requires EGFR Signaling.

Cell Commun Insights 2009 ;2:1-11

Center for Cell Biology and Cancer Research, Albany Medical College, Albany, NY, USA 12208.

TGF-β1 and its target gene encoding plasminogen activator inhibitor-1 (PAI-1) are major regulators of capillary outgrowth, vessel maturation and angiogenic network stability. The increasing realization of the complexity of PAI-1 action in the vascular system requires analysis of specific signaling events that impact its expression in a physiologically-relevant cell system. PAI-1 was required for tubular differentiation and maintenance of cellular survival in complex gels since targeted disruption of PAI-1 synthesis or activity with antisense constructs or function-blocking antibodies resulted in network regression.
