"Processing of transcription factors and bioactive peptides in plants"
Description: Proteolytic processing is a post-translational modification process that plays an important role in cell signaling. We have been studying the role of several subtilisin serine proteases in cell signaling in Arabidopsis and have investigated the role of two of these – one in the activation of membrane-bound transcription factors and another in the release of a bioactive peptide from a precursor protein. The membrane-bound transcription factors are activated in response to ER stress while the bioactive peptide is a plant growth factor activated by wounding. October 1, 2008

"Inhibiting tumor growth via vasoconstriction"
Description: A vasoactive peptide, endothelin-1 (ET-1), has been implicated in the development of prostate cancer. Through autocrine activation of its receptor, ETA, endothelin-1 is a strong mitogen. Conversely, ET-1, discovered originally as potent vasoconstrictor, can inhibit tumor formation and metastatic colonization via vasoconstriction of intra-tumoral vessels. My recent work suggests that the relative concentration of the ET-1 peptide in the tumor microenvironment is critical for determining a balance between its growth-suppressing (vasoconstriction) and growth-promoting (mitogenesis, survival, and angiogenesis) properties. These findings may have significant implications for the modification of current prostate cancer therapies involving ET-1. October 22, 2008

"Abscission signaling and cell wall remodeling in Arabidopsis stamen abscission zones"
Description: Cell separation within abscission zones (AZs) leads to plant organ detachment. We linked laser capture microdissection of Arabidopsis stamen AZs to whole genome profiling to reveal the AZ transcriptome responding to a shedding cue. AZ transcripts regulated at high statistical significance over five floral stages leading to post-pollination stamen detachment have been characterized in detail. Genomic data including hierarchical clustering of cell wall-related gene expression suggest a temporal model for abscission signaling and cell wall remodeling in stamen AZs.
