Dr. Wayne Bowen earned his B.S. in chemistry from Morgan State College in 1974, and completed his Ph.D. in biochemistry and neurobiology at Cornell University in 1981. After postdoctoral studies at the National Institute of Mental Health (NIMH), he initially came to Brown University in 1983, as Assistant Professor of Biology in the Section of Biochemistry where he taught endocrinology, introductory biology, and biochemistry and did research on opioid and sigma receptors in the brain. Shortly after promotion to Associate Professor, he moved back to the NIH in 1991 to establish the Unit on Receptor Biochemistry and Pharmacology within the Laboratory of Medicinal Chemistry of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). He returned to Brown University in 2004 to take his current position as Professor of Biology in the Department of Molecular Pharmacology, Physiology & Biotechnology in the Division of Biology and Medicine. In 2007, he assumed the position as department chair and was named Upjohn Professor of Pharmacology in 2008.
Dr. Bowen is a nationally recognized leader in research on sigma receptors, membrane proteins found in tissues throughout the body and that are highly upregulated in cancer cells. He has shown that activation of sigma-2 receptors induces apoptotic cell death, and therefore they may serve as regulators of cell proliferation and survival. He is interested in signal transduction, particularly those pathways that lead to receptor-mediated cell death. Trained initially as a chemist, he maintains a strong interest and involvement in medicinal chemistry and drug design, particularly in relation to development of selective sigma receptor agonists and antagonists. He is exploring these compounds as potential anti-neoplastic, tumor diagnostic, and neuroprotective agents.
Dr. Bowen currently co-directs the medical school's pharmacology course, teaches in endocrinology and neuroscience courses for undergraduates, and co-directs the core pharmacology course for the Molecular Pharmacology and Physiology Graduate Program. Dr. Bowen is a member of the Society for Neuroscience, the International Brain Research Organization/World Federation of Neuroscientists, and the American Association for Cancer Research. He is the recipient of numerous awards and honors, and has performed service on NIMH and NIDA Study Sections. He served as president of the NIH Black Scientists Association in 2001. Dr. Bowen's research has been funded by NIDA, NINDS, NIDDK, the Rhode Island Science and Technology Advisory Council, and a Salomon Award from Brown University.

Most work in our laboratory currently focuses on the possible role of sigma-2 receptors in regulation of cell proliferation and survival. We have found that chronic activation of sigma-2 receptors induces apoptosis in a wide variety of cell types. We are investigating the signaling mechanisms leading to the induction of cell death, and have found that these mechanisms are cell type-specific. For example, in breast tumor cells, apoptosis occurs via a novel mechanism that is both caspase- and p53-independent, whereas in neuroblastoma, cell death is dependent on caspase 8/10 activation. Signaling involves both transient and sustained changes in cytosolic calcium levels. We are interested in determining the mechanisms of calcium flux and the downstream effects of these calcium signals. Signaling also involves changes in cellular sphingolipids (ceramides and lysosphingolipids). Sphingolipids are involved in myriad cellular processes including cell survival, regulation of ion channels, and cell-cell recognition. Lysosphingolipids act via specific G-protein coupled receptors on the cell surface, as well as through certain intracellular targets, and ceramides are known to modulate the activity of various protein kinases and phosphatases involved in cell growth. We are investigating the role of sphingolipid signaling in neuronal and non-neuronal cells and how this system interfaces with sigma-2 receptors. Also under investigation are effects of sigma-2 receptor activation on mitochondria. Apoptosis in both neuronal and non-neuronal cell types appears to involve loss of mitochondrial membrane potential and release of mitochondrial apoptogenic factors. The roles of mitochondrial pro- and anti-apoptotic Bcl-2 family proteins are under study.
The study of a series of SN79 analogs has revealed a previously unknown function of the sigma-2 receptor. Some ligands in this series induce programmed cell death by mechanisms described above. However, other ligands induce no apparent change in cell viability, but rather appear to stimulate hallmarks of glycolytic cellular metabolism. This is initially evidenced by an increase in reduction of MTT dye, an effect blocked by sigma-2 antagonists. We have shown that ligands in this class induce an increase in ATP levels, a decrease in basal ROS level, and stabilization of HIF1α with subsequent induction of VEGF expression. These results suggest that sigma-2 receptors may play some role in regulating the Warburg effect (aerobic glycolysis) and enhancing the ability of cancer cells to survive in hypoxic environment. This effect would be consistent with the upregulation of sigma-2 receptors in cancer cells. We are investigating additional sigma-2 receptor-mediated changes in metabolic endpoints and attempting to elucidate upstream signaling mechanisms leading to this metabolic effect.
The sigma-2 receptor, a 21.5 kDa lipid raft protein, has recently been identified as the known protein, TMEM97. While little is known about the function of TMEM97, this discovery has made available molecular tools with which to study sigma-2R/TMEM97 and will greatly facilitate further studies of this receptor and its role in normal and cancer cell biology.
The sigma-1 receptor has been cloned and is a 25 kDa polypeptide with two putative transmembrane domains. In contrast to sigma-2 receptors, activation of sigma-1 receptors appears to exert protective and perhaps trophic effects on neurons and other cell types. Others have shown that activation of sigma-1 receptors potentiates neurite outgrowth in culture, whereas we have shown that activation of sigma-2 receptors causes neurite retraction. Blockade of sigma-1 receptors by selective antagonists or antisense deoxyoligonucleotides has been shown to block the toxic effects of cocaine, a psychotropic agent that binds to sigma-1 receptors. Furthermore, sigma-1 receptor activation in the hippocampus has a cognitive enhancing effect. We have initiated structure-function studies of the sigma-1 receptor and its role in tumor cell proliferation and survival. Sigma-1 receptors regulate calcium signaling by amplifying release of calcium from the endoplasmic reticulum in response to the rise in IP3 via GPCR activation. The sigma-1 receptor appears to signal solely by protein-protein interactions. The liganded receptor binds to ankyrin in the ER membrane and relieves a tonic inhibition of the IP3 receptor that is imparted by its interaction with ankyrin. We have shown that stable overexpression of sigma-1 receptors induces a constitutive activation of the IP3 receptor in human MCF-7 breast tumor cells, which are normally devoid of sigma-1 receptors. Furthermore, studies using various receptor constructs showed that only the C-terminal segment of the receptor is required for this effect. We are further delineating the functional domains of the receptor. Furthermore, cells overexpressing active sigma-1 constructs proliferate more rapidly than untransfected cells and have a survival advantage. We are investigating the signaling mechanisms that are involved in inducing what appears to be a more highly aggressive phenotype. The studies suggest that the sigma-1 receptor could be a biomarker for assessing proliferative status of tumor cells.
We are involved in the design and synthesis of novel small molecule ligands for sigma-1 and sigma-2 receptors. Since the natural ligand(s) is unknown and many existing sigma ligands interact with other receptors, selective synthetic probes for sigma receptors are necessary. Through close collaboration with medicinal chemists, we have developed and are continuing to develop highly selective receptor agonists and antagonists for use as tools to study receptor function. We are interested in elucidating the structural features of ligands that determine binding affinity, impart subtype selectivity, and that specify agonist/antagonist properties. Some of these compounds may have clinical potential as therapeutic agents.
Studies of sigma receptors will shed light on novel modes for regulation of cell proliferation and survival. It may be possible to target sigma-2 receptors with agonists or sigma-1 receptors with antagonists to induce apoptosis in tumors rendered drug-resistant due to acquisition of mutations in key components of the classical apoptotic pathway, such as p53 and caspases. Also, the potential role of sigma-2 receptors in cancer cell metabolism may lead to other targets to induce cell death. Sigma receptors in the CNS could conceivably play a role in neurodegenerative disorders. Furthermore, since typical neuroleptics such as haloperidol activate sigma-2 receptors, these studies may have important implications for treatment of psychiatric disorders with respect to the debilitating motor side effects induced by these agents.
