17/7/2020 20:09 | The field of microbiome research has evolved at a tremendous pace in recent decades, with mounting evidence that our microbial communities have a profound impact on our health. “To put it into context, we have a ballpark figure that the microbiome is about 150 times bigger than the human genome,” says Lindsay Hall, Microbiome Group Leader at the Quadram Institute, Norwich, UK. “So that begins to give a bit of an idea that it might be quite important for us!” Huge advances in sequencing technologies, paired with dramatic decreases in costs, have opened the door to studies exploring the collection of microbes that live on and within our bodies more comprehensively than ever before. “We’ve known for a long time that these communities are important for our health but trying to get a handle on their complexity was very difficult,” explains Hall. “But we can now drill down and have a look at these microbes and see what impact they have on our health.” Improving our knowledge of how the composition and function of our microbiome can influence aspects of our physiology holds great promise for the development of new ways to prevent and treat a range of medical conditions - such as infectious diseases, cancer, mental health disorders and autoimmune conditions. Sequencing the "dark matter" Although microbiome research is by no means new, for many years’ scientists were limited by the traditional microbiology methods that were available to study it. “The problem is that it is not possible to culture much of the microbiota under standard conditions,” explains W. Florian Fricke, Professor of Nutrigenomics at the University of Hohenheim, Stuttgart, Germany. “So for a long time, that part was overlooked.” But around a decade ago, the introduction of next-generation sequencing (NGS) technologies accelerated research into this hidden fraction of the microbiome. “We can now actually analyze microbial communities without having to grow them in the lab,” explains Alex Almeida, Postdoctoral Research Fellow at the European Bioinformatics Institute (EMBL-EBI) in Cambridge, UK. “This has allowed us to examine the diversity of the microbiome to a much greater depth.” Researchers use two main NGS approaches to analyze the microbiome. Metagenomics involves sequencing all of the DNA within a sample, while amplicon sequencing looks at specific bacterial "fingerprints" – typically by amplifying and sequencing fragments of the 16S rRNA gene. “Metagenomics is more expensive but provides a very deep, complete picture of the microbial community in a sample – so not just the bacteria, but also other organisms such as viruses too,” explains Fricke. “Amplicon sequencing is simpler and quicker and can tell you what bacterial species are present and their relative abundance.” Metagenomics produces a collection of short DNA fragments that scientists then try to piece together into individual bacterial genomes. “When you sequence a complex community like the human gut, you get lots of different bits and pieces from many different species,” explains Almeida. “On the computational side, we need to disentangle this diversity to try to tease apart the individual organisms.” But newer technologies can generate much longer sequences, enabling much greater resolution and accuracy. And chromosomal conformation capture techniques, such as Hi-C, can provide clues about the real-life proximity of two fragments within the sample. “If we know that two DNA molecules were closer together, we have a greater assumption that they belong to the same organism and this improves the analyses,” explains Almeida. “These techniques allow us to add another dimension to the sequencing data that we can retrieve.” Ongoing challenges NGS technologies combined with bioinformatics has led to an explosion of studies into the microbiome in laboratories around the world. “Thousands and thousands of samples are being sequenced and released to the public domain every month,” says Almeida. “The ability to analyze them consistently and reproduce the results that are done by different teams is a big challenge in the field.” To help tackle this issue, Almeida’s team at the EBI is responsible for MGnify, a centralized hub for microbiome-derived sequencing data, which as he explains is, “a free resource that enables researchers to deposit and analyze their data in a consistent manner.” Although the advent of advanced sequencing technologies has opened the door to exploring the microbiome in greater depth than ever before, several aspects of microbial communities remain inaccessible. “We still get a lot of ‘unknown’ Another limitation is that current methodologies often lead to the generation of compositional data rather than absolute quantitative information about the microbes within a sample. “You don’t usually keep the information of the original quantity of the microbiome that you analyzed, so in the end, you only get a percentage of an unknown total,” explains Fricke. “So we may find that 20% is bacterium X and 30% is bacterium Y – but we just end up with a relative abundance species catalog.” To get a handle on the full complexity of the microbiome, researchers will need to develop new approaches that enable them to uncover the quantitative relationships between major microbial groups. | manc10 | |
