Abstract
Yak endometritis is a
common postpartum disease that not only harms the reproductive health of yaks
but also causes significant economic losses to yak farming. MicroRNAs (miRNAs)
have been found to play vital roles in numerous inflammatory diseases. This
study aims to investigate the role of miR-184 in modulating LPS-induced
inflammation in the yak endometrial epithelial cells and to elucidate the
underlying molecular mechanisms involved. Uterine tissues were obtained from
three healthy yaks and three yaks diagnosed with endometritis, almost 21 days
postpartum. The results demonstrated that inflammatory cell infiltration and
structural damage of the endometrium in yak endometritis tissues, with
upregulated levels of IL-6, IL-1β, TNF-α expression, and downregulation of
miR-184. Similarly, in LPS-induced yak endometrial epithelial cells, miR-184
expression was significantly downregulated, while overexpression of miR-184
significantly declinedthe levels of IL-6, IL-1β, TNF-α expression and
inhibited the activation of the MAPK signaling pathway. Moreover, silencing ELK1
yielded similar results while the targeting relationship between miR-184 and
ELK1 was confirmed by dual luciferase reporter assay. Additionally, the
overexpression of miR-184 was found to inhibit ELK1 expression. This work
reveals the Latent regulatory mechanism of miR-184 in the inflammatory immune
response of the yak endometrial epithelial cells and proposes that miR-184 might
operate as a useful target for treating inflammation in the yak endometrial
epithelial cells.
