Signaling lipids such as diacylglycerol (DAG) and the phosphatidylinositol polyphosphates (PIPns) play crucial roles in numerous cellular pathways. However, characterization of their activities is hindered by the complexity of associated signaling pathways and of the membrane environment. To address this issue, we have developed lipid probes that are effective for characterizing biological events using different applications, including activity-based probing (PIPns and DAG) and microarray analysis (PIPns). The activity-based probes have been applied to label receptor targets in multiple cancer cell proteomes through photocrosslinking followed by click reactions. The probes were found to label several …

Enteral nutrition with eicosapentaenoic acid (EPA; 20:5 n-3) and γ-linolenic acid (GLA; 18:3 n-6) decreased pulmonary inflammation by reducing neutrophil counts and chemotactic factors in bronchoalveolar lavage fluid during acute respiratory distress syndrome (ARDS). We hypothesize that the antiinflammatory effects of EPA and GLA may be due, in part, to induction of neutrophil apoptosis. Neutrophil apoptosis is an important physiological process in the resolution of pulmonary inflammation. Furthermore, pro-inflammatory eicosanoids formed from arachidonic acid (AA) by lipoxygenase (LO) and cyclooxygenase (COX) pathways have been shown to inhibit apoptosis in certain cell types. The purpose of this dissertation is to determine …
