Mock communities assess differential gene expression methods in metatranscriptomics, suggesting improved analysis techniques.

The aim is to evaluate the robustness of differential expression testing methods in metatranscriptomics using real datasets.
Analyzed mock communities with known microbial properties to evaluate current metatranscriptomic approaches.
Applied these methods to gnotobiotic mice colonized by specific human bacterial strains.
Utilized metagenome-assembled genomes from a clinical study to refine analysis by excluding low information samples.
No method was robust against all types of confounding factors in real datasets.
The method identified from mock community tests demonstrated effectiveness in inferring microbial interactions.
Enhanced analytical techniques improved differential expression inference by addressing low prevalence challenges.

Lee et al. (2026) studied this question.
