...Maëlys Loh; Fred Bernard; Antoine Guichet ABSTRACT Microtubules and their associated motors are important players in nucleus positioning. Although nuclear migration in Drosophila oocytes is controlled by microtubules, a precise role for microtubule-associated molecular motors in nuclear migration...

...You Kure Wu; Hiroki Umeshima; Junko Kurisu; Mineko Kengaku ABSTRACT Nuclear migration of newly born neurons is essential for cortex formation in the brain. The nucleus is translocated by actin and microtubules, yet the actual force generated by the interplay of these cytoskeletons remains elusive...

... following enucleation. Consistent with this conclusion, the increased efficiency of reprogramming when using donor nuclei from embryonic cells could be explained, at least in part, by reintroduction of embryonic nuclear factors along with the donor nucleus. By contrast, cell cycle synchrony between...

... this transport takes place. We have identified a centriole-containing centrosome close to the oocyte nucleus. Remarkably, the centrosomal components, γ-tubulin and Drosophila pericentrin-like protein also strongly accumulate at the periphery of this nucleus.

The ability to cause oocyte activation was specific to nuclei transferred from fertilized embryos as nuclei from parthenogenetic embryos or cytoplasts from fertilized or parthenogenetic embryos did not induce activation. Nucleus-induced oocyte activation was associated...

...C. Aimar ABSTRACT The role of the cytoplasm and nucleus in the control of the length of the division cycle was investigated in Pleurodeles waltl eggs. Injection of spermine into enucleated eggs showed that the ability to cleave was not restricted just to the period of normal cytokinesis (T = 1·0...
