Studies of Aurora and Polo Kinases During Cell Division in C. elegans
… triggers the separation of sister chromatids at anaphase. Chromosome dynamics during meiosis are more complex, as homologous chromosomes separate in anaphase I, whereas sister chromatids remain attached until anaphase II. In meiosis, separase must cleave the cohesin REC-8 in a stepwise manner to …

Regulation of mitotic exit in Saccharomyces cerevisiae
… pathway, termed the Cdc fourteen early anaphase release (FEAR) network, which regulates the activation of Cdcl4 during early anaphase. I found that at the onset of anaphase, the FEAR network initiates the release of Cdc 14 from its inhibitor. During later stages of anaphase, the MEN …

In vitro maturation and fertilization of porcine oocytes and evaluation of male fertility
… metaphase I (EPromet I, LPromet I, and Met I), anaphase I (EAna I, MAna I, and LAna I), telophase I (Tel I), and metaphase II (Agg Met II, Not W-sp Met II, and Met II) by the criteria of chromosomal morphology. A morphological heterogeneity among the oocyte population was found before …

Context Dependent Regulation of Dicer Function During Oocyte-to-Embryo Transition
… with defects manifesting primarily during anaphase I. Furthermore, these mutations also result in the loss of maternal 26G endo-siRNAs, while miRNAs remain unperturbed. I find that in vitro synthetic asymmetric di-methylated Dicer helicase peptides promote interaction with ERI5, a …

The Role of Spindle Orientation in Epidermal Development and Homeostasis
… in cortical NuMA localization as cells enter anaphase. I found that inhibition of Cdk1 or mutation of a single residue on NuMA mimics this effect. I also revealed that this anaphase localization is independent of LGN and 4.1 interactions, thus revealing two independent mechanisms responsible …

Apareamiento intergenómico y formación de polen no reducido en híbridos trigo x aegilops
… as a bridge for gene transfer between species. Anaphase-I to mature pollen stages of wheat×Aegilops hybrids has been analysed. First and second meiotic division showed disturbances, some of them resulted in tetrads with 2n chromosome content. Fertility estimations have been done with both tetrad …
