Sister chromatids are tightly apposed at their centromeric regions, but it is not known whether this is due to cohesion at the functional centromere or at flanking centric heterochromatin. The Drosophila MEI-S332 protein maintains sister-chromatid cohesion at the centromeric region [3]. By ...

Sister chromatid exchange (SCE) was studied in bone marrow cells of six healthy individuals. Compared with peripheral blood lymphocytes, a remarkably low and constant rate of SCEs was observed, ranging from 3.64 to 4.65 per metaphase. The lower incidence of SCE can be related only partly to th...

Sister chromatid exchange in human populations: the effect of smoking, drug treatment, and occupational exposure Increased rate of sister chromatid exchange (SCE) in peripheral lymphocytes has been observed in smokers as compared to nonsmokers and in patients receiving certain cytostatic drugs. The ...
The B6.YTIR (XY) mouse develops bilateral ovaries despite the expression of the testis-determining gene Sry during gonadal differentiation. We reported that the oocytes of the XY female are defective in their cytoplasm, resulting in a failure in the seco
Cohesion between sister chromatids is established during DNA replication and depends on a multiprotein complex called cohesin. Attachment of sister kinetochores to the mitotic spindle during mitosis generates forces that would immediately split sister chromatids were it not opposed by cohesion. Cohesion ...
ARP2, F-actin, and ORC4, known to play roles in asymmetric meiotic division, were initially localized along the ooplasmic membrane and concentrated over the MII-spindle but lost their cortical polarity after activation while the sister-chromatids moved away from the oolemma in the oocytes from...
