Prothrombin is a vitamin K-dependent serine protease and plays pivotal roles in both procoagulant and anticoagulant pathway of hemostasis. In this study, we cloned the full-length cDNA of porcine prothrombin by cDNA library screening and SMART RACE technique. The full-length cDNA is 2027 bp, with a 1869 bp Open Reading Frame (ORF) coding 623 amino acids.(More)
OBJECTIVE Factor VII (FVII) and factor X (FX) are two predominant molecules of coagulation cascade. Whether porcine FVII and FX could efficiently work in human circulation is important for successful pig to human liver transplantation. We compared the genetic characterizations and coagulation activities of porcine and human FVII and FX to shed insight into(More)
FVII is a vitamin K dependent serine protease that plays a key role in extrinsic coagulation pathway. In this paper, we report the full-length cDNA sequences of rhesus monkey FVII. The full-length cDNA has 2424 bp, and predicts an open reading frame of 1416 bp corresponding to 472 amino acids. The deduced protein sequence of rhesus monkey FVII indicates the(More)
Epigenetic modifications in histones are crucial for proper sperm physiology, egg activation and reproductive development of males. The objectives of this study were to determine the conservation and interactomes of histone three (H3) and ascertain the expression dynamics of acetylated and methylated H3 lysine 27 (H3K27ac and H3K27me3) in spermatozoa from(More)
Rhesus monkeys (Macaca mulatta) are human's closest evolutionary relatives next to Chimpanzees, and they are widely used in biomedical researches. Analyses of the rhesus monkey trasnscriptome and the sequence divergence between monkey and human are of importantce to the development of scientific analyses and to the application and interpretation of the(More)
Glutathione-activated neocarzinostatin chromophore generates bistranded lesions in the hybrid formed by yeast tRNA(phe) and DNA complementary to its 31-mer 3' terminus. To elucidate the chemistry of the RNA cleavage reaction and to show that the lesions are double-stranded (ds), a series of shorter oligoribonucleotides containing the target sequence(More)
The characterization of porcine antithrombin III (ATIII)-a highly powerful anticoagulant-is essential for using porcine liver in xenotransplantation applications. The objective of this study was to clarify the functions of porcine ATIII through comparison with human ATIII. We cloned porcine ATIII and compared its important functional sites with those of(More)
The reliability of the rhesus monkey as an important experimental animal depends on its genetic concordance with human. During our assessment of the rhesus monkey as a preclinical model for coagulation-related research, we cloned the full-length cDNA of rhesus monkey factor X (FX) and compared its genetic characteristics and coagulation activity with those(More)
