    • The present invention relates to a method for increasing the efficiency of offspring production in producing animals belonging to the family Canidae (canines) by somatic cell nuclear transfer. More specifically, relates to a method for increasing the efficiency of production of cloned canines by a method for cloning canines comprising enucleating the oocyte of a canine to prepare an enucleated oocyte, fusing a nuclear donor cell with the enucleated oocyte to prepare a nuclear transfer embryo and transferring the nuclear transfer embryo into the oviduct of a surrogate mother, wherein the nuclear donor cell is cultured in a medium containing a specific cell cycle synchronization-inducing substance such as roscovitine in the preparation thereof. The method enables to clone canines with high efficiency, and thus can contribute to the development of studies in the fields of veterinary medicine, anthropology and medical science such as the propagation of superior canines, the conservation of rare or nearly extinct canines, xenotransplantation and disease animal models.
    • 本发明涉及通过体细胞核转移提高属于犬科(犬科)的动物的后代生产效率的方法。 更具体地,涉及通过克隆犬的方法来提高克隆犬的生产效率的方法,包括将犬的卵母细胞去核以制备去核卵母细胞,将核供体细胞与去核卵母细胞融合以制备核转移胚 并将核转移胚胎转移到替代母体的输卵管中,其中在其制备中,在含有特定细胞周期同步诱导物质如roscovitine的培养基中培养核供体细胞。 该方法能够高效地克隆犬科动物,从而有助于兽医,人类学和医学领域的研究发展,如高等犬传播,保护罕见或几乎灭绝的犬,异种移植和疾病 动物模型。

    • Isolated peptide substrates of Plk1 and nucleic acids encoding these peptides are disclosed. The peptides include two to ten repeats of the amino acid sequence set forth as X1X2AX3X4X5PLHSTX6X7X8X9X10X11X12 (SEQ ID NO: 1), in which within each repeat X1, X2, X6, X7, X8, X9, X10, X11, and X12 are each independently any amino acid or no amino acid, and X3 and X4 are each independently any amino acid. Methods of using these peptides to detect Plk1 activity in a sample are also disclosed. In some examples, the method includes contacting a sample with a disclosed peptide substrate of Plk1 in the presence of adenosine triphosphate, or an analog thereof, for a period of time sufficient for Plk1 to phosphorylate the PBIPtide. The presence and/or amount of the phosphorylated and/or the unphosphorylated peptide is detected, thereby detecting and/or quantitating Plk1 kinase activity in the sample.
