Follicular fluid content and oocyte quality: from single biochemical markers to metabolomics
Reproductive Biology and Endocrinology, 2009 The assessment of oocyte quality in human in vitro fertilization (IVF) is getting increasing attention from embryologists. Oocyte selection and the identification of the best oocytes, in fact, would help to limit embryo overproduction and to improve the ...

Advanced Science, EarlyView.ACLY is vital for early embryo development. IGF‐1 activates AKT to phosphorylate ACLY, driving its nuclear localization and recruitment of HATs (P300/HAT1), boosting acetyl‐CoA production and histone acetylation for transcriptional activation. Conversely, ACLY deficiency (via knockdown, knockout, or AKT inhibition) reduces nuclear acetyl‐CoA, disrupts ...

The Effect of the Follicle Size and Follicle Number Per Ovary on Oocyte Quality of Local Goat
Jurnal Kedokteran Hewan, 2007 This research was aimed to find out the relationship between the diameter of follicle and the different of follicle number on oocyte quality of local goat. The oocyte originated from the ovary was taken from the Slaughterhouse in Banda Aceh.

Activation of ADF/cofilin by phosphorylation-regulated Slingshot phosphatase is required for the meiotic spindle assembly in Xenopus laevis oocytes [PDF]
, 2013 We identify Xenopus ADF/cofilin (XAC) and its activator, Slingshot phosphatase (XSSH), as key regulators of actin dynamics essential for spindle microtubule assembly during Xenopus oocyte maturation.

Retrieval of Mouse Oocytes [PDF]
Journal of Visualized Experiments, 2007 To date, only a few studies have reported successful manipulations of Peromyscus embryogenesis or reproductive biology. Together with the Peromyscus Genetic Stock Center (http://stkctr.biol.sc.edu), we are characterizing the salient differences needed to develop this system. A primary goal has been to optimize oocyte/early embryo retrieval.

Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet
Advanced Science, EarlyView.The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.

AMP-activated Protein Kinase is Involved in Hormone-induced Mouse Oocyte Meiotic Maturation in vitro [PDF]
, 2008 We have previously shown that AMP-activated protein kinase (AMPK) can induce the resumption of meiosis in mouse oocytes maintained in meiotic arrest in vitro.

Advanced Science, EarlyView.The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.

Advanced Science, EarlyView.RSPO2 and GDF9:BMP15 heterodimers—core components of oocyte‐secreted factors (OSFs)—coordinate to shape the molecular architecture of preantral granulosa cells via gene‐specific synergistic and antagonistic regulation, mediated through CTNNB1–SMAD2 signaling crosstalk.
