New Strategic Plan for NIH Obesity Research Seeks to Curb Epidemic
To combat the obesity epidemic, NIH is encouraging diverse scientific investigations through a new Strategic Plan for NIH Obesity Research. More than one-third of adults in the U.S. and nearly 17 percent of the nation's children are now obese, which increases a person's chance of developing many health problems, including type 2 diabetes, heart disease, high blood pressure, fatty liver disease, and some cancers.
NIH funds research to reduce the prevalence of obesity and its health consequences (an investment of $824 million in fiscal year 2010, plus awards totaling $147 million made in the same year through the Recovery Act). The NIH strategic plan, developed by the NIH Obesity Research Task Force, recognizes that eating less and exercising more is easier said than done. Highlighting the crucial role of research in efforts to reduce obesity, the plan emphasizes moving science from laboratory to clinical trials to practical solutions, and is designed to help target efforts and resources in areas most likely to help. See more about the obesity strategic plan.
NIH Launches Largest Oil Spill Health Study:

A new study that will look at possible health effects of the Gulf of Mexico's Deepwater Horizon oil spill on 55,000 cleanup workers and volunteers has begun in towns across Louisiana, Mississippi, Alabama, and Florida.
The GuLF STUDY (Gulf Long-term Follow-up Study) is the largest health study of its kind ever conducted among cleanup workers and volunteers, and is one component of a comprehensive federal response to the Deepwater Horizon oil spill. The study is being conducted by the National Institute of Environmental Health Sciences, part of the NIH, and is expected to last up to 10 years. Over time, the GuLF STUDY will generate important data that may help inform policy decisions on health care and health services in the region. View additional information on the GuLF STUDY website.
NIH Researchers Create Comprehensive Collection of Approved Drugs to Identify New Therapies for Rare and Neglected Diseases
Researchers have begun screening the first definitive collection of thousands of approved drugs for clinical use against rare and neglected diseases. They are hunting for additional uses of the drugs hoping to find off-label therapies for some of the 6,000 rare diseases that afflict 25 million Americans. The effort is coordinated by NIH's Chemical Genomics Center (NCGC).
The researchers assembled the collection of approved drugs for screening based on information from the NCGC Pharmaceutical Collection database browser. This publicly available, Web-based application described in a paper appearing in the April 27 issue of Science Translational Medicine, provides complete information on the nearly 27,000 active pharmaceutical ingredients, including 2,750 small molecule drugs that have been approved by regulatory agencies from the U.S., Canada, Europe and Japan, as well as all compounds that have been registered for human clinical trials.
New Robot System to Test 10,000 Chemicals for Toxicity
Several federal agencies, including the NIH, have unveiled a new high-speed robot screening system--called Tox21--that will test 10,000 different chemicals for potential toxicity. The chemicals to be screened include compounds found in industrial and consumer products, food additives, and drugs. Tox21 is located at the NIH Chemical Genomics Center and merges existing agency resources (research, funding, and testing tools) to develop ways to more effectively predict how chemicals will affect human health and the environment. The screening system is a collaborative effort among the National Institute of Environmental Health Sciences, the National Toxicology Program, the National Human Genome Research Institute, the U.S. Environmental Protection Agency, and the U.S. Food and Drug Administration.
Training Institute on Dissemination and Implementation Research
On August 1-5, NIH will hold a five-day training session on dissemination and implementation health research. One of the most critical issues impeding improvements in public health today is the enormous gap between the best evidence-based strategies to improve health and what actually gets used and implemented in everyday practice. The science of dissemination and implementation seeks to address this gap by understanding how to best ensure that evidence-based strategies to improve health and prevent disease are effectively delivered in clinical and public health practice.
The Training Institute for Dissemination and Implementation Research in Health will feature a faculty of leading experts from a variety of behavioral and social science disciplines. The University of North Carolina at Chapel Hill's Center for Health Promotion and Disease Prevention will host the institute. View additional information about the training institute.
Summer Institute on mHealth

NIDCR Supplement to the Journal of Public Health Dentistry
NIDCR supported a supplemental issue of the Journal of Public Health Dentistry, which focused on behavioral and social intervention research essentials. This supplemental issue was published in March 2011 and featured seven topical, peer-reviewed articles on essential elements of intervention research. These essential elements are: the use of an intervention planning model to guide a program of intervention research; the appropriate use of health behavior theory to guide intervention research; ensuring that behavioral or social interventions are delivered with fidelity in research studies; the importance of testing for mediation in intervention research; ensuring that interventions will be acceptable to the target community; following a systematic model to move implement interventions in community settings; and integrating cost analyses into intervention research. Each of these topical articles was written by leaders in their respective fields, and accompanying each article were several brief commentaries from other thought leaders. NIDCR hopes that this supplemental issue will be a useful resource for investigators interested in behavioral and social intervention research to improve oral and craniofacial health.
Sjögren's Syndrome Genetic Resource
NIDCR is working with Institute-funded investigators to develop a resource for studying the genetics of Sjögren's Syndrome. Initially, this resource will be based on the Sjögren's Syndrome International Collaborative Clinical Alliance (SICCA) Registry, housed at the University of California, San Francisco (PIs: Lindsey Criswell & Caroline Shiboski). DNA specimens from more than 2,400 individuals with signs or symptoms of Sjögren's Syndrome, their biologic relatives, and controls will be used to generate high-density genome-wide genotyping at the Center for Inherited Disease Research (CIDR) at Johns Hopkins University. This genetic information, in conjunction with the extensive clinical information available from SICCA Registry participants, will accelerate genetic research in Sjögren's Syndrome by providing resources to identify regions of the genome and genetic variants that affect the risk of developing Sjögren's Syndrome. The genetic and clinical information will be available through NIH's database of Genotypes and Phenotypes (dbGaP) to maximize the benefit to the research community and the public. Later in 2011, this resource will likely include participants from the natural history study of Sjögren's Syndrome in NIDCR's Intramural Program (PI: Gabor Illei) and additional participants from the SICCA Registry.
NIDCR Launches New Website Homepage
The NIDCR homepage has a new look. This updated version provides faster access to science news, researcher interviews, funding opportunities, and popular oral health publications. Additional features include fly-out menus in the top navigation to help users quickly accomplish key tasks, an image gallery, and a toolbar that highlights NIDCR's social media presence. The A-Z index is also higher up on the page where visitors can more readily find it.
Thanks in part to the recent homepage improvements, user satisfaction with the NIDCR website is at an all-time high. NIDCR's current score on the American Customer Satisfaction Index (ACSI) survey is an 81. On ACSI's 100-point scale, a score of 80 or better is considered a superior score and can only be achieved if the website meets or exceeds user expectations. NIDCR is one of the top 33 government sites that scored 80 or higher in the first quarter of 2011. Visit the new homepage at http://www.nidcr.nih.gov/

Flipping the Switch
Targeted therapy is a buzzword in oncology. It's also fast becoming a clinical reality. In the February 1 issue of The Journal of Clinical Investigation, a team of NIDCR grantees report on a newly identified target with implications for a common oral cancer – squamous cell carcinomas. The team offers a remarkable glimpse into the powerful biochemical information to be gleaned from p63, p73, and its microRNAs. The scientists discovered a microRNA called miR-193a that p63 and p73 directly regulate and which serves as an on-off switch to promote either cell death or survival. According to the researchers, this discovery is particularly interesting because the go-to platinum-based chemotherapy drug cisplatin appears to inadvertently eliminate p63 from the mix, flicking the microRNA switch into the pro-survival "on" position, and helping squamous cell carcinoma tumor cells to withstand the drug's deadly effects.
In a proof-of-principle test of their initial data, the scientists measured the expression levels of miR-193a in 23 head and neck squamous cell carcinomas - all of which were treated preoperatively with the same cisplatin-containing chemotherapy regimen. They found the two most treatment-resistant tumors ranked in the top three for highest expression levels of miR-193a. Although their data are preliminary, the scientists say the results suggest that further research is needed to determine whether disrupting the miR-193a switch will assist cisplatin and other chemotherapy drugs to kill squamous cell carcinoma cells in p53-negative tumors. The authors of the study are Ory B, Ramsey MR, Wilson C, Vadysirisack DD, Forster N, Rocco JW, Rothenberg SM, and Ellisen LW at the Massachusetts General Hospital Cancer Center and Harvard Medical School, Boston, MA.
A Few Discoveries Away
In the February issue of the FASEB Journal, NIDCR grantees report that in mouse studies the salivary glands can be induced to serve as an inductive site of mucosal immunity. Until now, scientists knew that immune cells circulated to the salivary glands from others tissues (one of the scientific rationales for salivary diagnostics), but surprisingly no group had tested their inductive capability.
As described in their paper, the scientists directly injected live cytomegalovirus into submandibular salivary glands of several mice and thereafter detected the formation of ectopic follicles. Subsequent analyses showed that these follicles functioned as impromptu germinal centers, allowing antigen-presenting follicular dendritic cells to interact with B and T cells and set in motion the maturation and proliferation of white blood cells. Importantly, the scientists found that the immune response ultimately stopped the spread of the infection to other tissues. The authors noted that their findings suggested that there may be two distinct types of inductive sites within the mucosal immune system. The first is a "natural" inductive site, such as those found in the gut or nasal passage. These sites come equipped naturally with M cells (antigen-transporting immune cells), large populations of white blood cells, and distinct germinal centers. The second are "induced" inductive sites, such as those arising in the salivary and mammary glands. An induced site must be inoculated to generate new localized tissue, or follicles, and the needed responses of acquired immunity.
According to the authors, "The results reported in these studies support the concept that deliberate salivary gland immunization can serve as an alternative mucosal route for administering vaccines." More research, however, will be needed to establish how this alternative route can best be exploited. Collaborating on the study were Grewal JS, Pilgrim MJ, Grewal S, Kasman L, Werner P, Bruorton ME, London SD, and London L at the School of Dental Medicine, Stony Brook University, NY.
Detecting Early Tooth Decay
The first step to avoid drilling and filling a tooth is to catch decay early. Scientists show for the first time that a promising imaging technique can do just that. In the December issue of the journal Lasers in Surgery and Medicine, NIDCR grantees report that polarization sensitive-optical coherence tomography -- or PS-OCT as it is known--can be used to assess early tooth demineralization. In a study of 20 orthodontic patients, the researchers imaged pairs of structurally sound premolars that needed to be extracted. The investigators found that they could measure early demineralization on both the buccal and occlusal surfaces. They explained that an area of demineralization produces a rise in reflectivity or intensity in the PS-OCT image. This, in turn, causes a loss of intensity from the tooth's lower layers, and the dentinal enamel junction may no longer be visible below the lesion area. The extent of demineralization can be calculated by measuring the depth and intensity of the lesion area in the cross-polarization PS-OCT image. In most cases, the dentinal enamel junction was visible, indicating that PS-OCT penetrated sufficiently enough through the full thickness of the tooth enamel to acquire high quality images. The researchers concluded, "We believe the ability to acquire complete 3D images and monitor the lesion development over longer periods of time will greatly facilitate these studies and we plan future studies along these lines." The research was conducted by Louie T, Lee C, Hsu D, Hirasuna K, Manesh S, Staninec M, Darling CL, Fried D in the Department of Orofacial Sciences, University of California, San Francisco.
Challenging Innate Immunity
A hard-to-study oral bacterium has now entered the genomic era and the evolutionary tales written into some of its genes are surprising scientists. In the January issue of the journal Molecular Microbiology, an NIDCR supported researcher and colleagues take another fascinating look at a previously unknown component of T. forsythia's weaponry. It's a unique protease that they found encoded in T. forsythia's genome and later named karilysin. Proteases are scissor-like enzymes that all forms of life use to snip specific cellular proteins and start, stop, or otherwise synchronize a range of biological activities. But microbes also secrete proteases as weapons, for instance, to degrade peptides that their host produces as a first-line of defense against infection, called innate immunity. These pathogenic proteases, which poisonous snakes and insects also secrete in their venom, often belong to a family of enzymes called matrix metalloproteinases, or MMPs.
The researchers reported previously that karilysin closely resembles an MMP structurally. They also found that the protease inactivates the LL-37 antimicrobial peptide, suggesting one way that karilysin may contribute to chronic periodontitis. Now, they go further and elucidate the structure of one of karilysin's main catalytic domains, called Kly18, and take a remarkable turn into evolutionary biology. Comparing similar gene sequences across species, they found that the structure of Kly18 is evolutionarily much closer to the MMPs found in winged insects or mammals than those in bacteria. They concluded that the gene sequence encoding Kly18 must have been transferred from humans or another animal or insect to the bacterium, a biological phenomenon called horizontal gene transfer, or HGT. "This proposed example of HGT entailing the shuffling of a metazoan [part of the animal kingdom] MMP to a human pathogenic bacterium, which involves distinct domains of life, is both a short circuit of Darwinian evolution and a testimony to the compatibility of proteins and cellular mechanisms despite evolutionary divergence over billions of years." Collaborating on the study were Cerdà-Costa N, Guevara T, Karim AY, Ksiazek M, Nguyen KA, Arolas JL, Potempa J, and Gomis-Rüth FX from: the University of Louisville School of Dentistry, Louisville, KY; the Faculty of Dentistry, University of Sydney, Australia; the Institute of Dental Research, Westmead Centre for Oral Health, Sydney, Australia; Jagiellonian University, Krakow, Poland; and the Molecular Biology Institute of Barcelona, Spain.
LIPS and Saliva
Previously, a team of NIDCR scientists published a series of research articles on a promising experimental technique called LIPS (an acronym for luciferase immunoprecipitation technology) and its potential to streamline the diagnosis of Sjögren's syndrome. Their work involved detecting specific autoantibodies in serum. This raised the question of whether the extremely sensitive LIPS technique would also work using saliva, which mirrors virtually everything present in blood serum but at concentrations 1,000 to 10,000 times lower. As published online on January 6 in the Journal of Dental Research, the researchers provide a preliminary answer in the affirmative. The study involved 27 healthy controls and 27 people previously diagnosed with Sjögren's syndrome. The researchers collected whole saliva from the participants and examined the samples for the presence of two autoantibodies, Ro52 and Ro60. Both are strongly associated with Sjögren's syndrome and commonly tested for in people suspected of having the condition. However, about 30 percent of Sjögren's patients don't have autoantibodies in their serum for Ro52 or Ro60, suggesting the syndrome may have more than one biological trigger. The researchers report that LIPS detected Ro60 autoantibodies in 70 percent of the saliva of Sjögren's patients with 96 percent specificity. The technique detected R052 autoantibodies in 67 percent of the saliva of Sjögren's patients with 100 percent specificity. Specificity measures the proportion of healthy people who are correctly identified as not having the disease. The authors noted that autoantibody titers for both antigens were 4,000 fold lower by volume than in serum. The study was conducted by Ching KH, Burbelo PD, Gonzalez-Begne M, Roberts ME, Coca A, and Iadarola MJ from the Neurobiology and Pain Therapeutics Section, Laboratory of Sensory Biology, NIDCR, and Sanz I from the University of Rochester.
