Buffalo parthenogenesis TMT LC-MS/MS


ABSTRACT: Oocytes act as the genetic vector for zygote reprogramming, and stores a large amount of material that is required to regulate embryogenesis. However, to date, there is no report on the dynamic changes of maternal proteins and genes that occur during the early stages of the embryo, particularly studies that use proteomic techniques in buffalos. Here, an integrated single-cell RNA sequencing transcriptomic and quantitative proteomic analysis were employed to systematically explore the dynamic function of maternally-expressed proteins in parthenogenesis model of buffalo.The proteome of the buffalo was quantitatively analyzed during parthenogenesis of mature oocytes and the two-cell stage embryo. Of 1,908 quantified proteins, 123 differed significantly. The transcriptome was analyzed 8 stages (GV, MII, 2-cell,4-cell,8-cell,16-cell,morula,blastocyst)of buffalo using the single-cell RNA sequencing, and a total of 3567 unique genes were identified to be differently expressed between all consecutive stages of pre-implantation development. Bioinformatics studies and validated results indicated that maternal expression of the proteins possibly plays a role in the formation of cellular junctions firstly after parthenogenetic activation and the “maternal-to-zygotic transition” (MZT) process exists during parthenogenesis and occur between the 8-cell to 16-cell stage.

Maternal-effect genes are especially critical for early embryonic development after fertilization and until massive activation of the embryonic genome occurs. By applying a tandem mass tag (TMT)-labeled quantitative proteomics combined with RNA sequencing approach, the proteome of the buffalo was quantitatively analyzed during parthenogenesis of mature oocytes and the two-cell stage embryo. Of 1908 quantified proteins, 123 differed significantly. The transcriptome was analyzed eight stages (GV,  ...[more]
