Lipid Signaling: Roles in mitochondrial biology, spermatogenesis, diabetes, immune function, the CNS, platelet activation, and cancer; - Imaging Pancreatic β-cells using metabolomics and MRI.
The Frohman laboratory cloned and has been exploring translational roles for the mammalian family of lipid-signaling Phospholipase D genes for the two decades. PLD superfamily members are involved in many physiological and pathophysiological settings including immune defenses, cancer, neurodegenerative disease, diabetes, cardiovascular disease, and fertility. Among other approaches, we have recently been generating and publishing findings with mice lacking each of the PLD isoforms, and have uncovered a number of fascinating stories with human health relevance. Recent work has included exploring the potential of using a Phospholipase D small molecule inhibitor as a therapeutic in stroke, cardiovascular disease and cancer progression settings. Cell biological processes of particular interest include mitochondrial fusion and fission, subcellular trafficking of membrane vesicles during signaling activated exocytosis and endocytosis, viral trafficking through the Golgi complex, integrin activation, and receptor signaling.
Michael Frohman undertook training in a variety of disciplines including biochemistry, immunology, and developmental biology. During his postdoctoral fellowship, he developed the molecular biological technique known as “5’ RACE” which since has seen wide use, first in cDNA cloning and now in the cataloging of endogenous RNAi. The Frohman lab cloned the mammalian family of PLD isoforms in the mid-to-late ‘90s, and has since been exploring their function in numerous disease settings. Alumni of the Frohman lab have faculty positions in South Korea, Russia, and the USA.

Regulation of exocytosis, cell shape, and mitochondrial fusion by lipid signaling pathways
Our laboratory examines lipid signals that alter cell morphology, regulate mitochondrial fusion, and trigger subcellular trafficking of membrane vesicles during regulated exocytosis and endocytosis. Disease-related topics include neurodegenerative disease (Charcot-Marie Tooth syndrome), diabetes, cancer, and impaired phagocytic immune responses to pathogens.
The specific topic constitutes study of signaling pathways mediated by members of the superfamiles of enzymes known as Phospholipase D (PLD) and PI4P Kinase. Classic PLD is activated by a wide variety of agonists that signal through G-protein coupled or tyrosine kinase receptors. PLD has varied cellular roles including facilitating membrane vesicle trafficking and fusion of the vesicles into the plasma membrane during regulated exocytosis, and reorganizing the actin cytoskeleton. We are currently investigating roles for PLD and PI4P lipid kinase in actin cytoskeleton reorganization, myoblast differentiation and fusion, Glut-4 glucose transporter translocation, phagocytosis, and regulated exocytosis (insulin and histamine release). In addition, we are exploring a novel member of the PLD superfamily that localizes to mitochondria and regulates fusion, and the mechanisms through which diminished rates of fusion cause neurodegenerative disease.
