Semaphorin 3E‐Plexin‐D1 Pathway Downstream of the Luteinizing Hormone Surge Regulates Ovulation, Granulosa Cell Luteinization, and Ovarian Angiogenesis in Mice

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.

RSPO2 Coordinates with GDF9:BMP15 Heterodimers to Promote Granulosa Cell and Oocyte Development in Mice

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.

Adverse Effects of Trichothiodystrophy DNA Repair and Transcription Gene Abnormalities on Human Fetal Development [PDF]

, 2009
The effects of DNA repair and transcription genes in human prenatal life have never been studied. Trichothiodystrophy (TTD) is a rare (affected frequency of 10^-6^) recessive disorder caused by mutations in genes involved in the nucleotide excision ...

A review of luteinising hormone and human chorionic gonadotropin when used in assisted reproductive technology

Reproductive Biology and Endocrinology, 2014
Gonadotropins extracted from the urine of post-menopausal women have traditionally been used to stimulate folliculogenesis in the treatment of infertility and in assisted reproductive technology (ART). Products, such as human menopausal gonadotropin (hMG)

Efficient Somatic Cell Nuclear Transfer by Overcoming Both Pre‐ and Post‐Implantation Epigenetic Barriers

Advanced Science, EarlyView.
Mammalian cloning via SCNT is limited by several epigenetic barriers. Kdm4d/Kdm5b overexpression plus TSA treatment overcomes epigenetic barriers during pre‐implantation development, while tetraploid complementation replaces defective extraembryonic lineages to bypass H3K27me3 imprinting loss to overcome epigenetic barriers in post‐implantation ...
