Abstract

Backgrounds Gut microbiota is increasingly recognized as an important environmental factor that could influence the brain function and behaviors through the microbiota-gut-brain axis.Method Here, we used the germ-free (GF) mice to explore the effect of gut microbiota on hippocampal microRNA (miRNA) and messenger RNAs (mRNAs) expression.Results Behavioral tests showed that, compared to specific pathogen-free (SPF) mice, the GF mice displayed more center time, center distance and less latency to familiar food. Colonization of the GF mice with gut microbiota from SPF mice did not reverse these behaviors. However, 7 differentially expressed miRNAs and 139 mRNAs were significantly restored. Through microRNA Target Filter analysis, 4 of 7 restored miRNAs had 2232 target mRNAs. Among these target mRNAs, 21 target mRNAs levels were decreased. Further analysis showed that the most significant GO terms were metabolic process (GO: 0008152), binding (GO: 0005488) and cell part (GO: 0044464) for biological process, molecular function and cellular component, respectively, and the most significantly altered pathway was axon guidance (mmu04360).Conclusions These findings indicated that colonization of gut microbiota to adolescent GF mice was not sufficient to reverse the behavioral alterations. Gut microbiota could significantly influence the expression levels of miRNAs and mRNAs in hippocampus. Our results could provide original and valuable data for researchers to further study the microbiota-gut-brain axis.

  • Evidence from studies in germ-free rodents shows microbial regulation of miRNA expression in brain regions of importance for neuropsychiatry such as the amygdala, prefrontal cortex, and hippocampus.

    “evidence emerge from studies in germ-free rodents of microbial regulation of miRNA expression in brain regions of importance for neuropsychiatry such as the amygdala, prefrontal cortex, and hippocampus (Chen et al., 2017;Hoban et al., 2017;Moloney et al., 2017).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
