Prc1-rich kinetochores are required for error-free acentrosomal spindle bipolarization during meiosis I in mouse oocytes

Nature Communications, 2020
Oocyte meiosis must achieve spindle bipolarization without predefined spatial cues. Yoshida et al. demonstrate that spindle bipolarization during meiosis I in mouse oocytes requires kinetochores to prevent chromosome segregation errors, a phenomenon that

Kif11-haploinsufficient oocytes reveal spatially differential requirements for chromosome biorientation

EMBO Reports
Bipolar spindle assembly and chromosome biorientation are prerequisites for chromosome segregation during cell division. The kinesin motor KIF11 (also widely known as Eg5) drives spindle bipolarization by sliding antiparallel microtubules bidirectionally,

Generation of transchromosomic mice harboring HLA-A/B/C and human B2M via mouse artificial chromosome and triple BAC integration

Scientific Reports
Humanized transgenic mice carrying human genes are useful for research on gene function and disease. Bacterial artificial chromosomes (BACs) that carry human genomic sequences with regulatory elements enable the expression of transgenes at physiological ...

Complex Evolutionary History of the Y Chromosome in Flies of the Drosophila obscura Species Group. [PDF]

, 2020
The Drosophila obscura species group shows dramatic variation in karyotype, including transitions among sex chromosomes. Members of the affinis and pseudoobscura subgroups contain a neo-X chromosome (a fusion of the X with an autosome), and ancestral Y ...
