Age-associated telomere shortening in mouse oocytes
Reproductive Biology and Endocrinology, 2013 BackgroundOocytes may undergo two types of aging. The first is induced by exposure to an aged ovarian microenvironment before being ovulated, known as ‘reproductive or maternal aging’, and the second by either a prolonged stay in the oviduct before ...

Autism Research, EarlyView.ABSTRACT We investigated associations between maternal grandparents' age and autism spectrum disorders (ASD) in grandchildren, exploring differences by race/ethnicity. In a multigenerational California birth cohort study including 1,743,998 and 1,630,722 mother–child pairs (with 27,975 and 25,816 ASD cases, respectively), we examined ASD risk by ...

Expression of an atrial G-protein-activated potassium channel in Xenopus oocytes [PDF]
, 1993 Injection of rat atrial RNA into Xenopus oocytes resulted in the expression of a guanine nucleotide binding (G) protein-activated K+ channel. Current through the channel could be activated by acetylcholine or, if RNA encoding a neuronal 5HT1A receptor ...

Proposal for a classification of oocytes and follicles in the mouse ovary.
Journal of Reproduction and Fertility, 1968 The need to develop a common terminology to describe the components of the ovary has been felt for some time (Gatz, 1955; Wischnitzer, 1966). A standard nomenclature would greatly facilitate the comparison of results relating to the development of the ...

PLK4: Master Regulator of Centriole Duplication and Its Therapeutic Potential
Cytoskeleton, EarlyView.ABSTRACT Centrosomes catalyze the assembly of a microtubule‐based bipolar spindle, essential for the precise chromosome segregation during cell division. At the center of this process lies Polo‐Like Kinase 4 (PLK4), the master regulator that controls the duplication of the centriolar core to ensure the correct balance of two centrosomes per dividing ...
