| Abstract |
The present study aimed to determine the profile of differentially expressed circular RNAs (circRNAs) in infertile patients treated with acupuncture and moxibustion and verify the role of acupuncture and moxibustion in altering endometrial receptivity (ER). High‑throughput RNA sequencing and bioinformatics analysis of samples from six pairs of patients treated with or without acupuncture and moxibustion were conducted. The reliability of high‑throughput RNA sequencing was validated using reverse transcription‑quantitative PCR. The most significant circRNA functions and pathways were selected by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. A circRNA‑miR‑mRNA interaction network was constructed to determine the connection between circRNAs, microRNAs (miRs), and mRNAs. High‑throughput RNA sequencing identified 2,653 circRNAs. A total of 86 circRNAs was differentially expressed, of which 57 were upregulated and 29 were downregulated, between the acupuncture and moxibustion group and the control group. In the GO analysis, the identified BP terms were chromatin modification, positive regulation of transcription from RNA polymerase II promoter involved in unfolded protein response, oxidative DNA demethylation, regulation of transcription from RNA polymerase II promoter in response to hypoxia, and regulation of smooth muscle cell differentiation. The identified CC terms were nucleoplasm, nucleolus, nucleus, histone acetyltransferase complex, and annulate lamellae. The identified MF terms were methylcytosine dioxygenase activity, chromatin binding, zinc ion binding, histone binding, and protein binding. In the KEGG pathway analysis, the identified pathways were protein processing in endoplasmic reticulum, degradation of aromatic compounds, shigellosis, mTOR signaling pathway, bacterial invasion of epithelial cells, and prostate cancer. Circ‑SFMBT2, circ‑BACH1, and circ‑LPAR1 were significantly upregulated (P<0.05) and associated with numerous miRs and mRNAs. Acupuncture and moxibustion could impact ER by regulating the expression of circRNAs.
