  • INTRODUCTION: A recent genome-wide association study in European systemic sclerosis (SSc) patients identified three loci (PSORS1C1, TNIP1 and RHOB) as novel genetic risk factors for the disease. The aim of this study was to replicate the previously mentioned findings in a large multicentre independe

  • Overexpression of SETβ, a protein localizing to centromeres, causes precocious separation of chromatids during the first meiosis of mouse oocyte.
  • Qi ST, Wang ZB, Ouyang YC, Zhang QH, Hu MW, Huang X, Ge Z, Guo L, Wang YP, Hou Y, Schatten H, Sun QY.AbstractChromosome segregation in mammalian oocyte meiosis is an error-prone process, and any mistake in this process may result in aneuploidy, which is the main cause of infertility, abortion and many genetic diseases. It is now well known that shugoshin and protein phosphatase 2A (PP2A) play important roles in the protection of centromeric cohesion during the first meiosis. PP2A can antagonize the phosphorylation of rec8-cohesin at the centromeres and thus prevent rec8 from cleavage and maintain the cohesion of chromatids. SETβis a novel protein that physically interacts with shugoshin and inhibits PP2A activity. We thus hypothesized that SETβ may regulate cohesion protection and chromosome segregation during oocyte meiotic maturation. Here we report for the first time the expression, subcellular localization and functions of SETβ during mouse oocyte meiosis. Immunobloting analysis showed that the expression level of SETβ was stable from the GV stage to the MII stage of oocyte meiosis. Immunofluorescent analysis showed SETβ accumulation in the nucleus at the GV stage, while it was targeted mainly to the inner centromere area and faintly localized to the interchromatid axes from GVBD to MI stages. At the MII stage, SETβ still localized at the inner centromere area, but could relocalize to kinetochores in a process perhaps depending on the tension on the centromeres. SETβ partly co-localized with PP2A at the inner centromere area. Overexpression of SETβ in mouse oocytes caused precocious separation of sister chromatids, but depletion of SETβ by RNAi showed little effects on the meiotic maturation process. Taken together, our results suggest that SETβ, even though it localizes to centromeres, is not essential for chromosome separation during mouse oocyte meiotic maturation, although its forced overexpression causes premature chromatid separation.
