Mining Microbial Transcriptomes to Engineer Cell-Based Bacterial Biosensors in Gut-Resident Bacteroidaceae

The paper develops a pipeline to identify environment-responsive promoters in gut-resident Bacteroidaceae by mining transcriptomes and screening biosensors in vivo.

Microbiome histidine competition mediates dietary control of systemic imidazole propionate

This study shows dietary glutamate influences ImP production via microbial competition, affecting glucose tolerance and systemic ImP levels.

Engineered gut symbionts mediate cross-phylum antagonism to suppress uropathogenic Escherichia coli colonization

This paper engineers gut symbionts to secrete colicins that suppress uropathogenic E. coli colonization in mice.

Glucose uptake in mammalian cells measured by ICP-MS

The paper develops a method to measure 13C-labeled glucose and rubidium in biological samples using ICP-MS, demonstrating its ability to detect glucose uptake in skeletal muscles.
