Exploring the complex relationship between gut microbiota and risk of colorectal neoplasia using bidirectional Mendelian Randomization analysis.
Wanxin Li et al. Cancer Epidemiol Biomarkers Prev 2023 4

We find genetic liability to colorectal neoplasia may be associated with abundance of certain microbiota taxa. It is more likely that subset of CRC genetic liability variants changes gut biology by influencing both gut microbiota and CRC risk. This study highlights the need of future complementary studies to explore causal mechanisms linking both host genetic variation with gut microbiome and CRC susceptibility.

Linking the microbiome to CAR-T cell responses.
Zachariah DeFilipp et al. Nature medicine 2023 3

Disruption of the intestinal microbiota is implicated in the pathophysiology of numerous health conditions, and recent studies have identified the gut microbiome as a variable that can impact cancer immunotherapy outcomes. A new study found that the composition of the intestinal microbiome may predict clinical outcomes of CAR-T cell therapy for lymphoma, which could inform microbiota-based intervention strategies.

Multiomic signatures of body mass index identify heterogeneous health phenotypes and responses to a lifestyle intervention.
Kengo Watanabe et al. Nature medicine 2023 3

We report an atlas of cross-sectional and longitudinal changes in 1,111 blood analytes associated with variation in body mass index (BMI), as well as multiomic associations with host polygenic risk scores and gut microbiome composition, from a cohort of 1,277 individuals enrolled in a wellness program (Arivale). Machine learning model predictions of BMI from blood multiomics captured heterogeneous phenotypic states of host metabolism and gut microbiome composition better than BMI, which was also validated in an external cohort (TwinsUK). Moreover, longitudinal analyses identified variable BMI trajectories for different omics measures in response to a healthy lifestyle intervention.

Cardiometabolic health, diet and the gut microbiome: a meta-omics perspective.
Mireia Valles-Colomer et al. Nature medicine 2023 3

High-throughput omics techniques applied on microbiome samples (meta-omics) hold the unprecedented potential to shed light on the intricate links between diet, the microbiome, the metabolome and cardiometabolic health, with a top-down approach. However, effective integration of complementary meta-omic techniques is an open challenge and their application on large cohorts is still limited. Here we review meta-omics techniques and discuss their potential in this context, highlighting recent large-scale efforts and the novel insights they provided. Finally, we look to the next decade of meta-omics research and discuss various translational and clinical pathways to improving cardiometabolic health.
