Animals, including humans, have stable relationships with communities of microorganisms collectively referred to as the microbiota. These communities profoundly influence the biology of their hosts, impacting host features such as immune function, metabolism, and even so-called “higher” traits such...
Epithelial-to-mesenchymal transition (EMT) is a cellular lifestyle change that produces highly invasive cells that can migrate long distances in the body. These processes are critical for normal embryonic development but are often reactivated in disease states such as cancer...
Redox regulation plays a central role in signal transduction processes operating in the brain. Aberrant redox signaling is a hallmark of several neurodegenerative diseases such as Alzheimer’s disease, Huntington’s disease, Parkinson’s disease, Amyotrophic Lateral Sclerosis and various Ataxias. It...
Copper plays an essential role in human physiology. It serves as a cofactor to key metabolic enzymes that are required for respiration, neurotransmitter biosynthesis, detoxification of radicals, blood clotting, connective tissue formation, and many others processes. Through currently unknown...
Our laboratory studies the basic molecular mechanisms of programmed cell death, an evolutionarily conserved process to eliminate cells. Because these pathways normally contribute to the millions of cell deaths that occur per day per individual, defects in cell death...
Understanding how the information in the genome is utilized is one of the central questions in modern biology. It has become clear that a critical level of gene regulation occurs through the chemical modification of both the DNA itself...
Our laboratory’s research focuses on understanding (1) how cells measure levels of available nutrients and (2) how cells adapt to changes in nutrient supply to control metabolic homeostasis. Our studies have primarily centered on changes in cholesterol and oxygen...
The vertebrate central nervous system (CNS) is an amazingly complex structure composed of distinct subtypes of neurons and glia. Our lab aims to identify the molecular mechanisms that control the generation of the major cell types of the vertebrate...
Phospholipids are the building blocks of biological membranes. Membranes leverage the amphipathic chemistry of lipids to form bilayers that encapsulate a cell and its multitude of organelles. Such compartmentalization has enabled cells to separate biochemical pathways, establish specialized functions...
