G6PC2 and gestational diabetes: The expression of mmu-miR-338-3p, a homologue of hsa-miR-338-3p, and G6PC2 in mice liver was explored after administration with PBS, C-mUMSC-EXOs, G-mUMSC-EXOs, and si-circ-G-mUMSC-EXOs to evaluate the regulatory roles of hsa_circ_0046060/hsa-miR-338-3p/G6PC2 axis in GDM mice.
