Abstract
Background/Aim. Erbuzhuyu decoction (EBZYD) is a traditional Chinese medicine (TCM) formula and has been used in infertility treatment. Meanwhile, acupuncture is also used to treat female infertility. However, it is unclear whether EBZYD combined with acupuncture has better therapeutic effect. The aim of this study was to explore the effect of EBZYD combined with acupuncture and investigate its mechanism in superovulation mice. Methods. The mice received the treatment of EBZYD, acupuncture, EBZYD combined with acupuncture, or miR‐494‐3p agomir combined with EBZYD and acupuncture. The blastocysts’ number, endometrial microstructure, and endometrial thickness were observed, followed by the detection of endometrial receptivity‐related factors, PI3K/Akt/mTOR pathway‐related proteins, and miR‐494‐3p expression using quantitative real‐time polymerase chain reaction (qRT‐PCR) or western blot. Luciferase reporter assay was performed to confirm the targeting relationship between HOXA10 and miR‐494‐3p. Results. EBZYD combined with acupuncture treatment could increase the number of blastocysts, pinopodes, endometrial thickness, and the expression of endometrial receptivity‐related factors, and the treatment effect of EBZYD combined with acupuncture was better than EBZYD or acupuncture alone. In addition, EBZYD combined with acupuncture treatment activated PI3K/Akt/mTOR pathway and inhibited the expression of miR‐494‐3p. HOXA10 is one of the target genes of miR‐494‐3p. Overexpression of miR‐494‐3p reversed the therapeutic effect of EBZYD combined with acupuncture and suppressed the expression of HOXA10 and the activity of PI3K/Akt/mTOR pathway. Conclusion. This study suggests that EBZYD combined with acupuncture could improve endometrial receptivity in superovulation mice via miR‐494‐3p/HOXA10 axis.
