Abstract: The present invention belongs to the field of molecular biology and genetics, and in particular relates to a method for editing a bovine gene based on Pro-iCHI. The present invention provides a method for editing a bovine gene based on Pro-iCHI. Protamine is transiently expressed in gene-edited b-haSCs, which are then injected to mature oocytes to obtain reconstructed embryos. Protamine can eliminate abnormal DNA methylation resulting from oocyte intracytoplasmic haSCs injection and enable the nucli to compress into sperm-like structures, and the obtained bovine Pro-iCHI embryos can successfully develop into blastocysts, with a blastocyst rate comparable to that of the embryos obtained by in vitro fertilization. Moreover, in the present invention, a protamine-encoding gene is inserted into a Saccharomyces cerevisiae protein expression vector for transient expression, which ensures that abnormal DNA methylation is erased, without integration into the genome resulting in the insertion of exogenous genes.

A method including the steps of: transferring a recombinant plasmid expressing protamine into a sheep androgenetic haploid embryonic stem cell, then introducing the cell into a mature sheep oocyte, and performing activation and culture to obtain a sheep iCHI embryo without abnormal epigenetic modifications. In the present disclosure, abnormal methylations in iCHI embryos may be erased by transient expression of protamine in o-haSCs. The blastocyst rate of the prepared Pro-iCHI embryos is significantly higher than that of iCHI embryos, and is similar to that of IVF embryos. The resulting embryos can be used for embryo transfer to obtain semi-cloned gene-edited sheep, providing materials for subsequent breeding applications.
