Demonstration of the Role of Both a Ttr and a Psr Homologue Enzymes in the Respiration of Tetrathionate by an Environmental Bacterium Shewanella sp. ANA‐3

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Using a combination of deletion mutants' construction, phenotyping of these mutants and complementary biochemical analyses, we established that the environmental Shewanella sp. ANA‐3 is using both the tetrathionate reductase Ttr and the polysulfide reductase Psr to respire tetrathionate.

Harnessing Next‐Generation 3D Cancer Models to Elucidate Tumor‐Microbiome Crosstalk

Advanced Healthcare Materials, Volume 15, Issue 1, 9 January 2026.
Centralizes the microbiome within 3D tumor‐microbiome model platforms, including spheroids, organoids, 3D‐bioprinted constructs, and microfluidic chips, each enabling structured host‐tumor‐microbe studies. These systems support bacterial colonization, facilitating investigation of microbial impacts on tumor growth, immunity, and therapy. The microbiome

Effect of Butyrate‐Producing Enterobacteria and Proton Pump Inhibitors on Advanced Hepatocellular Carcinoma Treatment With Durvalumab and Tremelimumab

JGH Open, Volume 10, Issue 1, January 2026.
ABSTRACT Aim The gut microbiome modulates immune responses, and butyrate‐producing bacteria have been linked to improved immune checkpoint inhibitor (ICI) efficacy. Conversely, proton pump inhibitors (PPIs) may negatively impact ICI outcomes by altering gut microbiota.
