An interplay between non-coding RNAs and gut microbiota in human health

Humans have a complicated symbiotic relationship with their gut microbiome, which is postulated to impact host health and disease broadly. Epigenetic alterations allow host cells to regulate gene expression without altering the DNA sequence. The gut microbiome, offering environmental hints, can influence responses to stimuli by host cells with modifications on their epigenome and gene expression. Recent increasing data suggest that regulatory non-coding RNAs (miRNAs, circular RNAs, and long lncRNA) may affect host-microbe interactions. These RNAs have been suggested as potential host response biomarkers in microbiome-associated disorders, including diabetes and cancer. This article reviews the current understanding of the interplay between gut microbiota and non-coding RNA, including lncRNA, miRNA, and circular RNA. This can lead to a profound understanding of human disease and influence therapy. Furthermore, microbiome engineering as a mainstream strategy for improving human health has been discussed and confirms the hypothesis about a direct cross-talk between microbiome composition and non-coding RNA.

Automated summary

Humans have a complex relationship with their gut microbiome, which can impact health and disease through epigenetic alterations and non-coding RNAs. The interplay between gut microbiota and non-coding RNA, including lncRNA, miRNA, and circular RNA, is crucial in understanding human disease and developing therapies. Microbiome engineering is also explored as a strategy for improving human health by targeting the microbiome composition.
