After screening miRNAs in periods of peak-lactation and late-lactation, we have concluded that miR-181b shows a higher expression.
We established the regulating relation between miR-181b and its target gene IRS2, and conducted the rescue experiment to prove that miR-181b exercises its function indeed via IRS2.
We made a further research and discussion about the function of miR-181b and Wnt signaling pathway in the GMEC.
