The strongest associations with weight loss success or failure – independent of BMI – are found in the genetic capacity of the gut microbiome. These new findings open the door to diagnostic tests that can identify people likely to lose weight with healthy lifestyle changes and those who might need more drastic interventions.
Researchers from Institute for Systems Biology (ISB), Fred Hutchinson Cancer Research Center and other organizations have uncovered underlying metabolic changes that regulate how immune cells react to COVID-19. These findings are associated with COVID-19 severity and may predict patient survival. The work was published in the journal Nature Biotechnology.
ISB researchers and their collaborators looked at the electronic health records of nearly 630,000 patients who were tested for SARS-CoV-2, and found stark disparities in COVID-19 outcomes — odds of infection, hospitalization, and in-hospital mortality — between White and non-White minority racial and ethnic groups.
The gut microbiome is an integral component of the body, but its importance in the human aging process is unclear. ISB researchers and their collaborators have identified distinct signatures in the gut microbiome that are associated with either healthy or unhealthy aging trajectories, which in turn predict survival in a population of older individuals.
ISB researchers and their collaborators are looking beyond the one-drug, one-solution approach that has thus far failed in Alzheimer’s disease research. Instead, they are focusing on other promising research avenues, such as the possible role of the gut microbiome in dementia.
By analyzing blood plasma samples taken at several time points, ISB researchers have identified specific proteins that persistently presented as outliers and signaled metastatic cancer well before patients were diagnosed. The findings were published in the journal Scientific Reports.
Diseases develop gradually over years, sometimes decades, before symptoms appear, and are due to malfunctioning physiological processes brought about by our genes and environment. In research published in the journal Proceedings of the National Academy of Sciences (PNAS), ISB researchers have shown how an individual’s genetic risk for disease is often reflected in their blood.
There is a dichotomy between Bacteroides- and Prevotella-dominated guts — two common gut bacterial genera — and there is a significant barrier when it comes to transitioning from one to the other.
In the cellular process of differentiation, information about the concentrations of an important class of proteins residing in a cell’s nucleus has been lacking, a missing link needed for scientists to fully understand how the process works. ISB researchers have quantified this important class of proteins that play a key role in the formation of red blood cells.
Researchers at ISB harnessed deep molecular and physiological information to determine an individual’s biological age, which they found was reflective of overall health compared to chronological age. The findings were published in the Journals of Gerontology: Series A.
Predicting the alpha diversity of an individual’s gut microbiome is possible by examining metabolites in the blood. The robust relationship between host metabolome and gut microbiome diversity opens the door for a fast, cheap and reliable blood test to identify individuals with low gut diversity.
The Institute for Systems Biology and Arivale “Pioneer 100 Study” is featured on the cover of August’s Nature Biotechnology. The artwork was created by ISB’s Associate Director of Communications Allison Kudla in collaboration with contributing author John C. Earls, software engineer in the Hood-Price Lab. About the cover: A subset of statistically significant correlations are extruded in three-dimensional space. Price et al. describe the integration of whole genome sequences; clinical…
Institute for Systems Biology and Arivale “Pioneer 100 Study” Establishes Foundation for New Industry of Scientific Wellness. Personal, dense, dynamic data clouds enable novel insights into mechanisms of wellness and disease, new approaches to biomarker discovery, and the empowerment of individuals to enhance their own health.
April 25, 2017 A Cell-Surface Membrane Protein Signature for Glioblastoma 3 bullets: Using integrated protein and gene expression data, ISB researchers developed a 33-gene signature for glioblastoma, an aggressive form of brain cancer. Glioblastoma gene signatures are associated with TGF-b signaling and cancer invasion. Researchers think that some of the glioblastoma gene signatures have the potential to be used as blood biomarkers for this aggressive cancer. Read the full summary…
Feb. 27, 2017 ISB researchers and colleagues from several institutes published a new study today in Human Molecular Genetics. The key points of the study “High resolution time-course mapping of early transcriptomic, molecular and cellular phenotypes in Huntington’s disease CAG knock-in mice across multiple genetic backgrounds” are: A multi-institute collaboration mapped in high resolution the earliest effects of the Huntington’s disease mutation in mice. The study included four different genetic…
