Effect of the miR-125b/SUV39H1 axis on H3K9me3 levels and heterochromatin deposition.
A and B, immunoblotting analysis of H3K9me3 levels after knockdown of both miR-125b and SUV39H1 in BFFs (A) or SCNT embryos (B). Protein expression levels were normalized to histone H3 levels. C, qPCR analysis of satellite expression in SCNT embryos after knockdown of both miR-125b and SUV39H1 (*, p < 0.05). The GAPDH level was set to 1.0. Bars indicate the S.E. D and E, immunoblotting analysis of H3K9me3 levels after overexpressing both miR-125b and SUV39H1 in BFFs (D) and SCNT embryos (E). Protein expression levels were normalized to the histone H3 levels. F, qPCR analysis of satellite expression in SCNT embryos after overexpressing both miR-125b and SUV39H1 (*, p < 0.05). The GAPDH level was set to 1.0. Bars indicate the S.E.
