human microbiome project ppt

The rationale behind FMT is simple: antibiotics and other factors disrupt the normal balance of colonic flora and reduce colonization resistance, allowing pathogenic C. difficile strains to grow, leading to the typical clinical presentations of diarrhea and pseudomembranous colitis; by reintroducing normal flora via donor feces, the imbalance can be corrected, the cycle interrupted, and normal bowel function re-established. Obesity alters gut microbial ecology. Accurate phylogenetic classification of variable-length DNA fragments. OUTLINE OF TALK For example, specific changes in the gut microbiome have been linked to liver health. Ambient Ultrafine Particle Ingestion Alters Gut Microbiota in Association with Increased Atherogenic Lipid Metabolites. Clipping is a handy way to collect important slides you want to go back to later. Bian X, L Chi, B Gao, P Tu, H Ru and K Lu. Recent studies have suggested that the gut microbiome performs numerous important biochemical functions for the host, and disorders of the microbiome are associated with many and diverse human disease processes. Cole, J. R. et al. Launched in 2007, the first phase (HMP1) focused on identifying and characterizing human microbiota. The NIH Human Microbiome Project - Title: PowerPoint Presentation Author: proctorlm Last modified by: Brian Foy Created Date: 2/7/2012 4:49:41 PM Document . To address this need we present an innovative scalable comprehensive analysis workflow, a healthy human reference microbiome list . Understandably, there will be great pressure at early stages of the HMP to focus on disease states. NIH Human Microbiome Project.

Magis, Nature A combination of these two general strategies is likely to be the best approach to understanding the functions associated with each metagenome. 0000009837 00000 n Because the microbiome is a key interface between the body and the environment, these microbes can affect health in many ways and can even affect how we respond to certain environmental substances. An ever-growing number of studies have demonstrated that changes in the composition of our microbiomes correlate with numerous disease states, raising the possibility that manipulation of these communities could be used to treat disease. Also, the modification of bile acids by microorganisms affects lipid metabolism in the host44. Looks like youve clipped this slide to already. Several gut-microbiome data sets were analysed: a combined mouse gut data set (n = 5 animals)19 and two human gut data sets1.

NIEHS research uses state-of-the-art science and technology to investigate the interplay between environmental exposures, human biology, genetics, and common diseases to help prevent disease and improve human health. Germ-free mice have greater locomotor activity than their colonized counterparts43. Weve updated our privacy policy so that we are compliant with changing global privacy regulations and to provide you with insight into the limited ways in which we use your data. Flame retardants Early life exposure to types of flame retardants calledpolybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls(PCBs) can have a life-long impact on disease risk, which may be shaped by the gut microbiome. Non-HMP investment in microbiome research at the NIH has increased over forty-fold since the inception of the HMP and spans over 20 of the NIH Institutes and Centers. Environmental exposures can also disrupt a persons microbiome in ways that could increase the likelihood of developing conditions such as diabetes, obesity, cardiovascular and neurological diseases, allergies, and inflammatory bowel disease. 0000010337 00000 n von Mering, C. et al. Venter, J. C. et al. Well also hear how better understanding these complex interactions can help scientists develop interventions to slow, or even stop, progression of the disease. Bacteria-induced intestinal cancer in mice with disrupted Gpx1 and Gpx2 genes. (For example, Fourier-transform ion-cyclotron-resonance mass spectrometers have a mass accuracy of < 110 parts per million.) One important outcome is anticipated to be a deeper understanding of the nutritional requirements of humans. Germ-free animals have a smaller heart as a proportion of body weight than their colonized counterparts54.

Human microbes are believed to play a broad role in cancer diagnosis, pathogenesis, and treatment by interacting with the host immune system [2]. trailer <]/Prev 346489/XRefStm 1519>> startxref 0 %%EOF 251 0 obj <>stream 0000012113 00000 n The SlideShare family just got bigger. The renewal of gut epithelial cells is affected, in part, by interactions between the microbiota and immune cells. To address any question about the human microbiome, the microbiota needs to be sampled, and temporal and spatial scales need to be considered before undertaking this process. Welcome to the Biology Department | College of Science & Engineering Curr Opin Gastroenterol 31(1):6975. Important goals include the following: a minimum set of standards for annotation; a flexible, simple and open format for depositing metadata (taking a lesson from clinical studies because the relevant parameters are largely unknown); efficient analysis tools for the general user that are broadly applicable (including tools for meta-analyses of varied data types); and an adequate cyberinfrastructure to support the computing needs of the research community. The gut microbiome in health and in disease. We've updated our privacy policy. The SlideShare family just got bigger. Natl Acad. Pathogens Certain microbes, or pathogens, in the humanoral microbiome may play a role in either increased or decreased risk of pancreatic cancer. Because of statistical sampling issues, the Markov-model-based approach is likely to be relatively insensitive, especially for short sequences and for sequences from heterogeneous genomes. 112, 552559 (1982).

Turnbaugh, P., Ley, R., Hamady, M. et al. 2017. The gut microbial community has an effect on both the innate immune system48 and the adaptive immune system49, and it contributes to immune disorders that are evident within and outside the gut. 0000010709 00000 n At present, there are no methods to retrieve sufficient quantities of microorganisms from various body surfaces, such as the skin and the vaginal mucosa, in a reproducible and representative manner, and sufficiently free of human cells, so that the microbiome can be sequenced. The composition of thevaginal microbiome at birth can have lasting effects on offspring metabolism, immunity, and the brain. The new field of metagenomics involves the characterization of the genomes in these communities, as well as their corresponding messenger RNA, protein and metabolic products2. Enter HMP1.

NIEHS-supported research related to the microbiome includes a variety of environmental factors, including: Air pollution NIEHSfunded research found breathing ultrafine particles, a component of air pollution, altered the gut microbiome and changed lipid metabolism in mice with atherosclerosis. Wu, L. et al. Instant access to millions of ebooks, audiobooks, magazines, podcasts and more. The decreasing cost and increasing speed of DNA sequencing, coupled with advances in the computational approaches used to analyse complex data sets7,8,9,10,11, have prompted several research groups to embark on small-subunit (16S) ribosomal RNA gene-sequence-based surveys of bacterial communities that reside on or in the human body, including on the skin and in the mouth, oesophagus, stomach, colon and vagina12,13,14,15,16,17 (see page 811). Tools and databases for metabolite identification still need to be developed, despite the existence of highly accurate instrumentation. Research has yielded tremendous insight into the links between the microbiome, environmental exposures, and human health. It is expected that the HMP will uncover whether the principles of ecology, gleaned from studies of the macroscopic world, apply to the microscopic world that humans harbour (see page 811). 0000166522 00000 n Weve updated our privacy policy so that we are compliant with changing global privacy regulations and to provide you with insight into the limited ways in which we use your data.

Sci. 2018 Chronic stress promotes colitis by disturbing the gut microbiota and triggering immune system response. The homology-search-based approach is probably more accurate and provides the additional advantage of placing each sequence in the context of a multiple alignment and a phylogenetic tree, which can then be used in further studies. Rapid reversal of hyperoxaluria in a rat model after probiotic administration of Oxalobacter formigenes . And it is one element of a worldwide effort to document, understand and respond to the consequences of human activities not only as they relate to human health but also as they relate to the sustainability of the biosphere.

Second, it will be necessary to find better, faster and more scalable heuristics for generating huge phylogenetic trees that contain millions of sequences. We've updated our privacy policy. Gao B, Bian X, Mahbub R, Lu K. 2017. The two general marker-independent approaches to phylogenetic assignment are to use Markov models based on the frequency of short nucleotide sequences (or 'words') in the reads and to use homology searching to place each sequence fragment in the context of a phylogenetic tree. The advent of highly parallel DNA sequencers and high-throughput mass spectrometers with remarkable mass accuracy and sensitivity is propelling microbiology into a new era, extending its focus from the properties of single organism types in isolation to the operations of whole communities.
