A paper on mechanisms for prevention of aneuploidy during fertilization has been published.

Eggs fuse with sperm to give rise to a fertilized egg. Mori (Research Scientist), in collaboration with Dr. Ikawa from Osaka University, showed that sperm-derived chromosomes are spatially separated from egg-derived chromosomes, which prevents aneuploidy in the fertilized egg.

RanGTP and the actin cytoskeleton keep paternal and maternal chromosomes apart during fertilization.

A paper on the influence of life stage and calorie restriction on aging-associated transcriptome changes in oocytes has been published.

Oocytes exhibit aging-associated chromosome segregation errors, which results in aneuploidy in eggs. Mishina (SPDR) and Tabata (PhD student from Kyoto Univ) et al showed that life stage and calorie restriction influence aging-associated transcriptome changes in oocytes, in collaboration with Nikaido and Hamada labs in BDR.

Mishina T*, Tabata N*, Hayashi T, Yoshimura M, Umeda M, Mori M, Ikawa Y, Hamada H, Nikaido I and Kitajima TS. (*These authors contributed equally to this work.)
Single-oocyte transcriptome analysis reveals aging-associated effects influenced by life stage and calorie restriction.
