Michael A. Miller (b. 1971) received his Ph.D. in 1999 from the University of California at Irvine in the Department of Biological Chemistry. His postdoctoral training was done in David Greenstein’s lab at Vanderbilt University in the Department of Cell & Developmental Biology. He joined the UAB Department of Cell Biology in 2003 and was appointed to Associate Professor with tenure in 2009.

Research/Clinical Interest

Function and evolution of intercellular communication mechanisms
Multicellular organisms depend on intercellular communication or signaling mechanisms to coordinate the movement, differentiation, and proliferation of their cells. In humans, aberrant regulation of cell communication is the basis for many types of cancer, inflammatory disease, neurological disease, and infertility. Studies of distantly related animals are consistent with the hypothesis that a core, but incompletely discovered set of signaling mechanisms is used reiteratively during development to control basic cellular functions. We primarily use the nematode Caenorhabditis elegans as a simple in vivo model for discovering fundamental signaling mechanisms and elucidating their mechanisms of action. Our current focus is on two hormone classes critical for reproduction, lipid hormones called prostaglandins and protein hormones called MSPs. These two hormones mediate communication between sperm and egg that controls sperm motility and oocyte meiotic maturation, respectively. Prostaglandins are the targets of non-steroidal anti-inflammatory drugs, such as aspirin and ibuprofen. MSPs comprise a recently discovered, widespread class that bind to Eph receptors and other receptors. The human genome encodes fourteen Eph receptors, which are broadly expressed and implicated in vascular development, stem cell proliferation, nervous system functions, and oncogenesis. A point mutation in the VAPB MSP domain causes amyotrophic lateral sclerosis and late-onset spinal muscular atrophy, two neurodegenerative disorders. Research projects aim to discover biological roles of MSPs and prostaglandins, to determine how these hormones function, and to investigate their evolutionary origins.
