Over the last few decades, gut microbiota research has been the focus of intense research and this eld has become particularly important. This research aimed to provide a quantitative evaluation of the 100 most-cited articles on gut microbiota and IBS and highlight the most important advances in this eld. MethodsThe database Web of Science Core Collection (WoS) was used to download the bibliometric information the top 100 most-cited papers. Microsoft Excel 2021, CiteSpace, VOSviewer, R software, and an online analytical platform (https://bibliometric.com/) were was applied to perform bibliometric analysis of these papers. ResultsThe total citation frequency in the top 100 article ranged from 274 to 2,324, with an average citation of 556.57. A total of 24 countries/regions made contributions to the top 100 cited papers, and USA, Ireland, and China were the most top three productive countries. Cryan JF was the most frequently nominated author, and of the top 100 articles, 20 listed his name. Top-cited papers mainly came from the Gastroenterology (n = 13, citations = 6,373) and Gut (n = 9, citations = 3,903).

MicroRNAs (miRNAs) are a class of short noncoding RNAs that regulate gene expression through the binding of their 5'-end to mRNA. However, the biological effects of miRNA's 3'-end binding to mRNA remain unclear. Here we discover that the pairing of miRNA's 3'-end with RNA could serve as a primer to initiate the production of miRNA-derived RNAs (midRs), in the opposite direction of its originating RNA. midRs could consequently translate into miRNA-derived proteins (midPs). Starting from 2,656 Homo Sapiens miRNAs, we predicted 11,453 and 1,239 unique midRs and midPs for humans using a 15-nucleotide-pairing threshold. We verified the bona-fide existence of example midRs and midPs in human cells. Of clinical relevance, we demonstrate that midP0188 is highly expressed in human lung and breast cancer tissues and cells and that midP0188 and its encoding midRs represent novel anti-cancer targets. Our findings propose a miRNA→midR→midP axis that expands the central dogma and reveals thousands of novel RNAs and proteins that have immense potential for playing crucial biological and pathological roles in human cells, as well as other biological systems.

Cryan JF was the most frequently nominated author, and of the top 100 articles, 20 listed his name. Top-cited papers mainly came from the Gastroenterology (n = 13, citations = 6,373) and Gut (n = 9, citations = 3,903).

Conclusion This study identified and provided the bibliometric information of the top 100 cited publications related to gut microbiota and IBS.
