The EC50 values for hGCSF purified from MBP-hGCSF and PDIb’a’-hGCSF were consistent with a previous study that reported an EC50 value in the range of 0.8–6 pM for hGCSF. At high concentrations, the purified hGCSF proteins induced mild inhibition of cell proliferation, resulting in a bellshaped biphasic dose-response curve. This is consistent with a previous report that other cytokines also show a biphasic dose-response curve. During DEM-assisted enucleation, DEM induces formation of a membrane Regorafenib purchase protrusion that contains a mass of condensed maternal chromosomes, which can be easily removed with minimal damage. This simple method may prove useful for nuclear transfer and has garnered much attention. Here, we assessed changes in the level of MPF and the distribution of cyclin B1 in porcine oocytes following treatment with DEM. We also compared the efficiencies of DEMassisted and mechanical enucleation, and the development of embryos generated from these enucleated oocytes by SCNT. Our previous study demonstrated that brief treatment of MII porcine oocytes with DEM produces a membrane protrusion that contains a mass of condensed chromosomes, as seen in DEMtreated bovine oocytes and nocodazole-treated rat oocytes. Although the mechanisms by which DEM elicits its effects are unclear, condensation of maternal chromosomes might cause the protrusion to develop. Yin et al. reported that following treatment with 0.4 mg/ml DEM and 0.05 M sucrose for 1, 3, 6, 12, or 24 h, chromosomes were condensed in 100%, 97%, 87%, 96%, and 74% of porcine oocytes, respectively. Such protrusions are frequently observed in DEMtreated bovine and rabbit oocytes. Sucrose does not affect the formation of a cytoplasmic protrusion containing chromosomes in pig oocytes, but does enlarge the perivitelline space. Therefore, the current study investigated the effects of DEM treatment on oocytes. Tetsuya et al. demonstrated that DEM treatment of bovine oocytes increases MPF activity, as indicated by an increase in histone H1 kinase activity of up to 30%. Wu et al. showed that DEM induces membrane protrusions in goat oocytes by increasing the activities of MPF and mitogen-activated protein kinase via activation of MAD2. Further studies confirmed that MAD2 activates MPF mainly by preventing proteolysis of cyclin B. Several studies have indicated that treatment of somatic cells with microtubuleinteracting agents increases MPF activity. Although a number of studies have examined somatic cell responses, however, few studies have examined the effects of MPF on oocytes, and it is unknown SCH772984 molecular weight whether DEM increases MPF activity in pigs. These findings provide a further insight into the mechanisms of salusins in atherosclerosis, suggesting potential targets for the prevention and treatment of atherosclerosis. The Sanger sequencing method was developed in 1977, and it remained the primary method of genome sequence analysis for approximately 25 years. The subsequent automation of this method led to many key large-scale accomplishments ranging from the first completed sequence of the 16,569-base pair human mitochondrion in 1981, to first bacterial genome sequence.
