STAT3 Is an Upstream Regulator of Granzyme G in the Maternal-To-Zygotic Transition of Mouse Embryos.

ABSTRACT: The maternal-to-zygotic transition (MZT), which controls maternal signaling to synthesize zygotic gene products, promotes the preimplantation development of mouse zygotes to the two-cell stage. Our previous study reported that mouse granzyme g (Gzmg), a serine-type protease, is required for the MZT. In this study, we further identified the maternal factors that regulate the Gzmg promoter activity in the zygote to the two-cell stage of mouse embryos. A full-length Gzmg promoter from mouse genomic DNA, FL-pGzmg (-1696~+28 nt), was cloned, and four deletion constructs of this Gzmg promoter, Δ1-pGzmg (-1369~+28 nt), Δ2-pGzmg (-939~+28 nt), Δ3-pGzmg (-711~+28 nt) and Δ4-pGzmg (-417~+28 nt), were subsequently generated. Different-sized Gzmg promoters were used to perform promoter assays of mouse
