RESEARCH: Prof. Yancey's research is described below, with additional information found by clicking the blue topics:

Most of the research in Prof. Yancey's laboratory focuses on Organic Osmolytes: compounds that cells accumulate under dehydrating osmotic stress. Such stresses include high salinity (as in seawater, or in the interior of mammalian kidneys), evaporation (as in deserts), freezing, dietary imbalances, and diseases (e.g., high glucose in diabetes mellitus). Organic osmolytes can be built up in cells to reduce osmotic water loss; and, unlike salt ions, they do not disrupt cellular macromolecules. Moreover, many osmolytes have cytoprotective properties such as stabilizing proteins against denaturing agents like urea, temperature, and pressure in the deep sea.

Trimethylamine oxide (TMAO)

[add O or an SH to the S-group to
form taurine or thiotaurine, respectively]

Prof. Yancey and others have found that some osmolytes, especially methylamine types such as TMAO (left), can actually stabilize proteins and counteract destabilizing effects of perturbants such as urea, salt, temperature and pressure. TMAO has a breakdown product, TMA (trimethylamine), that makes marine animals smell "fishy." Methylamines are high and appear to protect proteins in
i) sharks and relatives, which also have the perturbing compound urea as an osmolyte;
ii) mammalian (including human) kidneys, which must concentrate urea as a perturbing waste;
iii) deep-sea animals which must cope with protein disturbances from high pressure. Our discovery of TMAO's role in the deep sea was featured in a New Scientist news story in 1999 and in a 2012 cover story of Science News. See Deep-sea Fish page for pictures and Deep-Sea Research page for research details.

--Stabilizing properties of osmolytes may have practical applications, e.g., Welch and colleagues have shown that TMAO and other osmolytes can prevent the damaging protein of "mad-cow" disease from forming, and can cause the malformed protein of cystic fibrosis to fold properly. (Dr. Yancey assisted in one of the latter studies; see Howard et al. reference below in Research Area 2.)

--We are also studying the role of osmolyte-type solutes in animals at hydrothermal vents and gas seeps, which have high levels of hydrogen sulfide, a gas toxic to most animals. A major osmolyte in shallow-water marine invertebrates such as clams and crabs is taurine. Taurine is also essential for mammalian brain development, and is the primary ingredient in many so-called energy or sports drinks (hint: the name taurine is derived from Taurus [bull]). Researchers in France have found high levels of the taurine derivatives hypotaurine and thiotaurine in clams, mussels and tubeworms which have sulfide-oxidizing bacterial symbionts. Thiotaurine, a product of hypotaurine and sulfide, may be a mechanism to prevent sulfide toxicity. We have found hypotaurine and thiotaurine in vent snails, limpets and heat-loving paralvinellid worms without symbionts, and shown that thiotaurine levels vary with sulfide exposure in these animals kept in laboratory pressure chambers. See Seeps and Vents page for pictures and Deep-Sea Research Page for research details.

--Other researchers have found that the common osmolyte of marine algae, DMSP (dimethylsulfonoproprionate), breaks down into the gas DMS (dimethylsulfide), which is largely responsible for the "smell of the sea" that evokes emotional responses to the ocean. DMS is also thought to trigger the seeding of clouds, in what may be a global temperature negative feedback process. This is one of the postulates of the so-called Gaia hypothesis, which suggests that global warming will cause more DMS production, which via cloud formation may cool the planet.
-- We have recently been working on DMSP and other osmolytes in coral animals and their symbionts, with Dr. Mary Hagedorn,who is hoping to cryopreserve coral larvae for potential re-seeding of decimated reef habitats.
