Fig. 5 Effect of AKG on cell-cell communication between cumulus and oocyte (A) The interaction weight plot of COCs. The thickness of the line indicates the number of interactions, and the stronger the interaction weight/intensity between the two cell types. Bar plot showed the total interaction weight of COCs in each group. (B) The up-regulated (increased) signaling ligand-receptor pairs were identified by comparing the communication probabilities in AKG30 samples and other samples. (C) Immunoblotting of <t>GDF9</t> in control, 30 and 750 µM AKG treated oocytes. (D) The expression of GDF9 in oocytes, expressed using log2(TPM + 1), n = 8. (E) the fluorescence intensity of oocytes Calcein-AM to indicate the changes of Cumulus cell-oocyte gap junction permeability during oocyte maturation, n = 9. (F) Representative images of the fluorescence intensity of F-actin on the zona pellucida to indicate the changes of transzonal projections (TZPs) during oocyte maturation. (G) Line graph showed the changes of TZPs during oocyte maturation
