Ribosomes are responsible for the synthesis of proteins, major component cellular biomass. Classical experiments have established a linear relationship between fraction resources invested in ribosomal proteins and rate balanced growth microbial population. Very little is known, however, about how investment ribosomes varies over individual cells We therefore extended study resource allocation from populations to single cells, using combination time-lapse fluorescence microscopy statistical...
Microbial physiology exhibits growth laws that relate the macromolecular composition of cell to rate. Recent work has shown these empirical regularities can be derived from coarse-grained models resource allocation. While studies focus on steady-state growth, such conditions are rarely found in natural habitats, where microorganisms continually challenged by environmental fluctuations. The aim this paper is extend study microbial strategies dynamical environments, using a self-replicator...
Abstract Marine microorganisms form complex communities of interacting organisms that influence central ecosystem functions in the ocean such as primary production and nutrient cycling. Identifying mechanisms controlling their assembly activities is a major challenge microbial ecology. Here, we integrated Tara Oceans meta-omics data to predict genome-scale community interactions within prokaryotic assemblages euphotic ocean. A global genome-resolved co-activity network revealed significant...
Dietary intervention is a cornerstone of weight loss therapies. In obesity, dysbiotic gut microbiota (GM) characterized by high levels Bacteroides lineages and low diversity. We examined the GM composition changes, including 2 enterotype (Bact2), in real-world study subjects following high-protein hypocaloric diet with or without live microorganisms (LMP) supplement.263 volunteers were part this program. The first phase was low-carbohydrate calorie restriction LMP supplements. Fecal samples...

Abstract Bispecific antibodies targeting CD3 on T cells and GPRC5D plasma (talquetamab) demonstrated promising efficacy in multiple myeloma, but acquired resistance usually occurs within a few months. Using single-nucleus multi-omic strategy 3 patients with talquetamab resistance, we identified two mechanisms of inactivation, by bi-allelic genetic or long-range epigenetic silencing its promoter enhancer regions. Investigating the molecular profiles target genes may help guiding choice...
Background: Bispecific antibodies (BsAb) are monoclonal that redirect T cells by targeting both the cell co-receptor CD3 and markers expressed on surface of tumor cells. BsAb BCMA (teclistamab) or GPRC5D (talquetamab) demonstrated promising efficacy in relapsed refractory multiple myeloma (RRMM) recent phase 1-2 studies. However, ~30% patients did not respond, half responders experienced disease progression within 12 months. Thus, it is crucial to understand mechanisms innate acquired...
Fermenting S. cerevisiae cells suspensions undergo synchronized metabolic oscillations whose amplitude and frequency depends on the population density.The asymptotic population-level dynamics is qualitatively quantitatively accounted for by mathematical models describing intracellular glycolytic coupling through external medium.Such dynamical systems often display low-dimensional parameters that fit experimental observations.However, high dimensionality of chemical space possible existence...
