Meet new CEEH member Dr. Anne Manicone

The CEEH Career Development and Mentoring Core welcomed Dr. Anne Manicone as a junior investigator early this year. Anne is an Assistant Professor in the Department of Medicine, Division of Pulmonary and Critical Care. She will join the CEEH Cardiopulmonary & Metabolic Disease Collaborative Research Team (CRT) headed by Drs. Mike Rosenfeld and William AltemeierAnne presented her research at the monthly CEEH Breakfast Club on January 28 in an informal talk titled Regulation of Macrophage Polarization: Implications in Lung Injury and Repair. She is currently focused on the role of MMP28 in regulating macrophage influx and activation, and the role of macrophage subpopulations in regulating lung injury and its resolution.

More specifically, Anne is characterizing the role of matrix metalloproteinase 28 (MMP28) in regulating the inflammatory response to tobacco smoke-induced emphysema in a mouse model. MMPs comprise a family of extracellular proteinases that function in various processes of innate immunity. MMP28 is one of the newest members of this family, and it is expressed by both macrophages and epithelial cells. Her work suggests that MMP28 inhibits inflammation and promotes reparative macrophage function. In her preliminary studies, MMP28 was shown to be protective in chronic emphysema from cigarette smoke; and her hypothesis is that this is mediated by MMP28-dependent effects on macrophage polarization.  Ongoing work is aimed at uncovering the mechanism and substrates by which MMP28 functions. 

Dr. Manicone's work is pertinent to Chronic Pulmonary Obstructive Disease (COPD) and pulmonary fibrosis, conditions brought on by environmental exposures such as smoking, asbestos, and air pollution, as well as asthma and genetics. Anne indicates she is always interested in collaborations.

The Career Development and Mentoring Core (CDMC), directed by Mike Rosenfeld, works to ensure that the University of Washington recruits, supports, and retains for DEOHS and other Center-affiliated departments (Epidemiology, Genome Sciences, Pharmaceutics), a new generation of high-caliber EHS-focused investigators with a strong interest in gene-environment interactions. The CDMC provides mentorship to new and current CEEH junior faculty to ensure they achieve their full potential as scientists, teachers, and communicators, as well as provides unique career development opportunities and resources to advance their environmental science careers by incorporating a gene-environment approach into their research projects.

Event Highlight: Third Annual Center Research and Public Engagement Awards

The 2014 Annual CEEH Awards for Innovations in Research and Public Engagement were presented at the Annual Center Retreat on December 3rd. 

The Innovations in Research Award recognizes the author or authors of a single, high-impact publication supported by CEEH and celebrates ground-breaking research that furthers the CEEH mission of building capacity, facilitating collaboration through communication, and inspiring creativity, which promotes innovative research, engages stakeholders, and launches the next generation of research and ecogenetics (gene-environment interactions) researchers.

The 2014 Innovations in Research Award went to Ed Kelly and co-authors Zhican Wang, Jenna Voellinger, Cathy Yeung, Danny Shen, Kenneth Thummel, Ying Zheng, Giovanni Ligresti, Dave Eaton, Kimberly Muczynski, Jeremy Duffield, Thomas Neumann, Anna Tourovskaia, Mark Fauver, Greg Kramer, Elizabeth Asp, and Jonathan Himmelfarb for their paper "Innovations in preclinical biology: ex vivo engineering of a human kidney tissue micro perfusion system" published in Stem Cell Research and Therapy.

Kidney disease affects more than 20 million adults in the US, yet little is understood about the impact of kidney disease on drug disposition. There is a need for improved understanding of drug efficacy, safety, and toxicity, especially during drug development. Kelly and his team plan to model the human kidney tubule interstitium using a 3-dimensional modular microphysiological system using cells derived from the human kidney. This system is intended to accurately reflect human physiology, allowing the researchers to predict how the kidneys handle drug disposition, and to assess kidney injury and the biological response to injuries caused by toxicants from both within and outside the body.

The Public Engagement Award recognizes an individual or team for creative, innovative, and meaningful work with communities beyond the university.

The 2014 Public Engagement Award went to PhD candidate Lorelei Walker for her creative and informative 3-minute video, “Engaging Epigenetics: A Tool for Stakeholder Education”, funded in part by the CEEH Community Outreach and Engagement Core (COEC). 

Lorelei's animated video describes epigenetics as the process that regulates our genes. All our cells have the same DNA: Our brain, skin, and white blood cells are different because epigenetics turns different genes on and off in different types of cells. If this epigenetic system is altered, genes can be turned on and off in the wrong cells or at the wrong time. 

Some chemicals can change our epigenetics and how our genes are regulated. The video uses pesticides, BPA and air pollutants as examples of chemicals that can remove gene regulators, and with excessive exposure, make us more vulnerable to getting sick. 

The video concludes by encouraging viewers to avoid BPA and foods with high pesticide residues, be informed voters, and to advocate for a healthier environment for ourselves and our children. 

Congratulations to Ed Kelly and team, and to Lorelei Walker. Keep up the great work!

Native Environmental Health Stories Project at the University of Washington

Native TEACH tribal researchers gather around Tribal Liaison Valerie Segrest (seated, center)
The Center for Ecogenetics and Environmental Health (CEEH) at the University of Washington in Seattle partnered with the Southwest Environmental Health Sciences Center (SWEHSC) at the University of Arizona for the Native Environmental Health Stories project, a supplement grant from the National Institute of Environmental Health Sciences (NIEHS). The activities at the UW CEEH were a continuation of its Native TEACH (Tradition, Environment And Community Health) Project that began in 2009.

The purpose of the original Native TEACH project was to identify the core concepts of Native environmental health science, as distinct from the mainstream western understanding of environmental health science. The current project was based on what was learned previously about Tribal members’ knowledge, beliefs and understandings of human interactions with their environment, and the value of traditional storytelling as a way to communicate complicated ideas.

CEEH hired a Tribal Liaison, Ms. Valerie Segrest, to lead the project. Valerie is an enrolled member of the Muckleshoot Indian Tribe whose reservation is located south of Seattle at the base of Mt. Rainier. She is a native foods educator and community nutritionist.

Ms. Segrest invited seven Native researchers from six Washington Tribes to attend a kickoff meeting at the University of Washington. The group learned about the Native Environmental Health Stories Project, participated in group exercises about environmental health, and brainstormed what groups in their tribal communities to bring together to talk about the question: What does environmental health mean in our community?

Over the next month, the researchers led conversations in their own tribal communities, which included Chinook, Muckleshoot, Lower Elwha S’Klallam, Port Gamble S’Klallam, Puyallup, Spokane and Yakima. The conversations took place in a tribal college class, Mom’s group, Team Teach, and an artists’ panel at a public art show.

These are some of the products that grew out of the tribal community conversations:

A public Art Exhibit, “Freeing the River”, was held at the Lower Elwha S’Klallam Tribe Heritage Center and featured four Lower Elwha tribal artists who displayed works based on the removal of two 100-year-old dams on the Elwha River. Restoring the Elwha River to its natural flow has helped restore historic salmon runs.

Native TEACH researcher and Lower Elwha S’Klallam tribal member Roger Fernandes, said, “I was taught that the salmon is the source of life for all beings, animals, plants, and the earth itself. The spirit of the salmon and the Salmon People allow us to live a life of abundance and gratitude. The art I have included in this show focus on the salmon and the return of the salmon with the removal of the dams. I was taught that the Elwha River was dammed against the wishes of the Lower Elwha S’Klallam people and that they have been fighting for the removal of the dams for several decades. Because the dams had no fish ladders, they were designed to essentially destroy the wild salmon runs. Because of the work of many of our ancestors and elders we have seen the dams removed and the salmon’s return. Life is in order again.” Photos of the art and a summary of the art show can be found on the CEEH blog

The Native TEACH researcher from the Port Gamble S’Klallam Tribe, Tleena Ives, is involved with a home visiting grant for expectant and new moms. Ms. Ives held her community conversation with the Mom’s group. She collected quotes from the moms and created a children’s book, t̕aʔt̕ə́wəsnaʔ in the S'Klallam language. 

The story goes like this: “You are a Star, This is my wish for you. This is my dream. This is my hope.” Tleena says that the conversation and the children’s book “helps bring power to our people, keeps our traditions alive, highlights what’s important and what we value, and what we want to pass on.” CEEH will publish the children’s book to share with the families in the Mom’s group and with the tribal Head Start families. Tleena and the Mom’s group have generously offered to share the children’s book with CEEH.

The Native TEACH researchers also created two overarching products to summarize the Native Environmental Health Stories project: 

  •  A 10-minute Native TEACH Digital Story. Each of the researchers is interviewed in their home setting talking about their research and the projects they created, one of which is an original song featured in the video.  
  • A year-long calendar blog posted month by month. Each month focuses on a tribal community and includes 4 topics: An Environmental Health Challenge, Community Art Project, Traditional Food, and a Call to Action. A new blogpost appears each week. 
The CEEH Community Outreach and Engagement Core (COEC) looks forward to future collaborations with our new tribal partners.

Event Highlight: The Living Breath of Wǝɫǝbʔaltxʷ Symposium

Huckleberries are a traditional food of Northwest Tribes
  The Center for Ecogenetics & Environmental Health was a sponsor of the UW American Indian Studies Department 2nd Annual Symposium, The Living Breath of Wǝɫǝbʔaltxʷ. The symposium was held Sept 26-27 at the UW Center for Urban Horticulture.

  Wǝɫǝbʔaltxʷ (listen) is a Lushootseed word that means Intellectual House. The conference title honors the Wǝɫǝbʔaltxʷ that UW is building on campus, the culmination of a 40-year dream of the Native community. Phase One of the Wǝɫǝbʔaltxʷ, a longhouse-style building that pays homage to the Coast Salish culture and architecture, is scheduled to open in February 2015. The Wǝɫǝbʔaltxʷ exemplifies the spirit of sharing, cooperation and commitment to indigenous knowledges and local and national indigenous communities. The symposium showcased the kind of work that will be done in this new space.

   The Living Breath of Wǝɫǝbʔaltxʷ symposium began by acknowledging the Duwamish tribe on whose traditional land we were meeting. Next came the Opening Prayer with drum accompaniment and Welcome Song by the Nuu-chah-nulth singers of Vancouver Island, BC. Two young Nuu-chah-nulth children from the tribal school joined their teacher who led the Welcome Song. Many challenges and disparities remain, but here is a victory: A Native teacher in a tribal elementary school teaches tribal children their language, songs, and cultural traditions.

   A team of presenters told about the Swedafzali or "place of mountain huckleberries" (Lushootseed), a 2-square mile plot of land at 5000 feet elevation in the Mount Baker/Snoqualmie National Forest. The land belonged to Weyerhaueser, and the lumber company clear cut the trees and and subsequently donated the plot to the US Forest Service (USFS). Through a partnership between the Tulalip Tribe and USFS, the tribe is restoring the land and planting mountain huckleberries, which are the most pure and medicinal when grown at high elevation. The damaged land is recovering, the huckleberries are profuse, and families are coming to gather. Some tribal members want to camp overnight. Next will be a campsite and rules to preserve the habitat, and negotiating the right to do traditional burning to keep encroaching trees off the huckleberry meadow. Native gathering rights off the reservation are guaranteed in the 1855 Treaty of Point Elliott between the US Government and Coast Salish tribes. This partnership improves the tribe's access to traditional food.

   Another panel discussed whaling culture and food access. Prof. Charlotte Coté (Tseshaht/Nuu-chah-nulth) and Micah McCarty (Makah), special assistant to President Obama for tribal and government relations at Evergreen State College, told of their tribes' whaling culture and nearly a century in which they have lacked access to whale meat and blubber. When Charlotte Coté told her mentor at UC-Berkeley that she wanted to write her dissertation about native culture, the mentor told her to study the Navajo. Instead she went home and talked to her relatives and tribal elders and decided to study the Nuu-chah-nulth whaling culture. Her dissertation is available here: Spirits of our Whaling AncestorsMcCarty reported that the Makah Tribe conducted one gray whale hunt, in 1999, an event of international significance. The right of the Makah tribe to hunt whale has been tied up in court since 2004.

    An audience member reported that the sockeye run is abundant this year, but the fish are too large. He said the small fry are eating fish food that spills through the nets on fish farms, and more of the fry survive, but they grow too fast and they eat the wrong food. Even a success story has a shadow side.

   Symposium attendees were served meals featuring traditional foods. We enjoyed strawberries, blueberries, raspberries, apples, and dense, seed-filled muffins; salmon, huckleberries, wild rice, and elk jerky. I noticed there were no bananas at breakfast. And I missed dessert. It hit home which foods were local and which weren't available or, like dairy, weren't part of a traditional diet. But the large urn of coffee? It was popular, but was that traditional?

   The event continued Saturday when our collaborator on the Native TEACH project, Valerie Segrest, coordinator of the Muckleshoot Food Sovereignty Project,  participated in the panel on Northwest Tribal Food Sovereignty.

   Discussions helped spread awareness about the issue of food sovereignty and food security. Planning Committee chair Charlotte Coté reported, “It’s a coming together of people who have an interest in traditional indigenous foods, sharing stories, ideas, and strategies about how we can protect those foods.” It was The Living Breath of Wǝɫǝbʔaltxʷ.

Research Highlight: Infant Diet found to Exceed EPA Guidelines for Phthalate Exposure

Dr. Sheela Sathyanarayana
Center member Sheela Sathyanarayana's work on phthalate exposure is getting new attention. A recent paper in the June issue of Environmental Health was followed by articles in ASPPH, the Association of Schools & Programs of Public Health, and the Washington Post.

Read about it here:

Washington Finds Infant Diet Exceeds EPA Guidelines for Phthalate Exposure

Significant exposure to endocrine-disrupting chemicals may come from our diet, particularly from dairy products and other high-fat foods. New findings by researchers at the University of Washington School of Public Health show that adolescents and infants may be especially vulnerable to high exposures of phthalates in their diet, exceeding even the US Environmental Protection Agency’s guidelines. The study was published in the June 2014 issue of Environmental Health.

Commonly used as plasticizers in food packaging, phthalates can leach out of packaging because of their chemistry. These endocrine-disrupting chemicals have been linked to adverse health effects, particularly in prenatal and early life exposures. Increased maternal urinary concentrations of metabolites have been associated with shorter anogenital distance in male infants, signaling the exposures may have an effect on male hormones and the development of male sex characteristics.

Samantha Serrano, M.S.

Samantha Serrano, MS, and Dr. Sheela Sathyanarayana, an adjunct assistant professor in the School of Public Health, investigated how certain foods affect dietary exposure to phthalates. They analyzed data from 17 studies that measured phthalate concentrations in United States and international foods, three epidemiological association studies, and three interventions.

Cooking oils, cream-based dairy products, and meats, particularly poultry, had high phthalate concentrations.

The estimated phthalate exposure in a typical diet consumed by adolescents and women of childbearing age fell below the EPA maximum acceptable dose. However, the exposure estimate for a typical diet in infants ages 1-2 exceeded the EPA maximum dose, and a diet high in meat and dairy went over the threshold by approximately four times. For adolescents, a diet high in meat and dairy also exceeded the EPA maximum acceptable dose.

Dr. Russell Dills from the University of Washington, Dr. Joseph Braun from Brown University, and Dr. Leonardo Trasande from New York University also contributed to this study, which was funded by the National Institute for Environmental Health Sciences and the University of Washington Department of Environmental and Occupational Health Sciences.

Event Highlight: Lower Elwha Klallam Art Show illustrates impact of the dam removal

Blue Salmon Paddle by Darrell Charles

Lower Elwha Klallam Tribe (LEKT) member Roger Fernandes and The Legacy Gallery organized an Art Show on May 23rd at the Lower Elwha Klallam Heritage Center in Port Angeles. After visiting Port Angeles last June to see the Elwha River Restoration, (see blog), I was eager to attend.

LEKT artists Linda Wiechman, Darrell Charles, and Roger Fernandes exhibited their work, ranging from paintings to drumheads to carved canoe paddles like the one pictured above. The focus was the impact that removing the Elwha River dams has had on the tribe and the environment. Linda and Roger led a panel discussion, and among those who attended were LEKT Council chairman Francis Charles and former Tribal Council member Dennis 'Sully' Sullivan.

The Elwha and Glines Canyon dams blocked the salmon from migrating up the Elwha River to spawn. The chinook would swim 5 miles upriver and find themselves blocked by the Elwha Dam. They hung in the water beneath the dam. In the first years after the dam was built, the salmon would smash their heads against the dam until the river was bloody. Salmon runs have dwindled since the dams were built, and some have gone extinct.

In native lore, salmon are the Salmon People who live in villages under the ocean and come back to the rivers to feed the people. Roger told us, We are the salmon people. Our culture is built around salmon. Northwest tribes have many traditional stories about the salmon.

The artists reported that when they were children, their parents and elders told them the dams would come down someday. The tribe's struggle to make that happen lasted for 30 years. It wasn't a political struggle, it was spiritual, a battle for a way of life. The LEKT never gave up. Roger said, They don't call us 'The Strong People' for nothing

For the Lower Elwha Klallam Tribe, the Elwha River Restoration means recovery of the salmon and the ecosystem. 

Linda Wiechman said, The river is life. Releasing the dams brings life back to the salmon people, and salmon bring back the whole ecosystem. Salmon are good medicine. Roger Fernandes said, Removing the dams is a huge statement about environmental wellness. When the salmon return, the ecology returns. 

According to Tribal Council Chairman Francis Charles, We do this for the children, for the future. Sully Sullivan recalled that when he was a child, fishing by tribal members was illegal. He and his friends learned to hide from the game warden and families hid their smoked salmon under their beds. But the people never stopped fishing.

Elementals of Nature by Linda Wiechman

Linda's painting, Elementals of Nature, depicts the recovering ecosystem. The river runs through cedar forest and snowberries. 

Eagle stands about to feed on a salmon whose remains will enrich the riverbank. Kingfisher observes, and so does Sasquatch, a shy being who stays in the background. Can you find the Sasquatch in the trees?

Another of Linda's paintings, The Changer, shows a mythical being who has created the salmon. Releasing the salmon into the river will restore the ecosystem. 
The Changer by Linda Wiechman

Lady of the Mountain Breaks the Dam
by Roger Fernandes
Roger Fernandes' painting, Lady of the Mountain Breaks the Dam depicts the mythical woman who sleeps. She helped make creation, then went to the mountains, promising to come back if ever she was needed. Here she is, tearing down the dam so the natural world can come back. As she frees the river, a salmon swims upstream. Thunderbird overlooks the scene; in native lore, Thunderbird drives the salmon up the river.

Roger Fernandes says, The river is free, the salmon are returning. But removing the dams is not the end, it's the beginning of something. It's still a figuring-out process. We changed the world, the environment is being re-established. Now we have to figure out what to do with that. 

Roger plans to bring the art show to The Legacy Gallery in Seattle this summer.

As for the ongoing Elwha River Restoration, new beaches are forming at the mouth of the river and marine life is showing up that's been missing for decades. Dive surveys in the summer of 2013 found juvenile crabs on the floor of the strait off the river mouth. Crab pots are being set near the mouth of the river.

Oregon Sunshine (Eriophyllum lanatum) is blooming on the drained bed of former Lake Aldwell. This perennial sunflower was planted from seed as part of the restoration, 

The Elwha Water Facilities Project, Port Angeles' water treatment plant that shut down because of river sediment, is operating again. And less than 30 feet of the Glines Canyon Dam remains to be torn down. Dam removal will resume after the spring river flows slow, and after June 30th when the fish migration ends. Dam removal is scheduled to be completed in fall, 2014. For more about the Elwha River Restoration, take a look at our blog series.
