Expression and regulation of estrogen receptor 2 and its coregulators in mouse granulosa cells

The Journal of Reproduction and Development, 2022
The cooperative effects of estrogen and oocyte-derived paracrine factors (ODPFs) play critical roles in the normal development of ovarian follicles; however, the mechanism underlying this cooperation has not been well studied.

Current approaches for assisted oocyte maturation in camels

Journal of Animal Reproduction and Biotechnology, 2021
Camel (camelus dromedarius) is a unique large mammalian species that can survive harsh environmental conditions and produce milk, meat, and wool. Camel reproduction is inferior when compared to other farm animal species such as cattle and sheep.

oocytes [PDF]

, 2012
In Drosophila oocytes, after the completion of recombination, meiotic chromosomes form a compact cluster called the karyosome within the nucleus, and later assemble spindle microtubules without centrosomes.

PLK1 inhibition delays mitotic entry revealing changes to the phosphoproteome of mammalian cells early in division

The EMBO Journal
Polo-like kinase 1 (PLK1) is a conserved regulator of cell division. During mitotic prophase, PLK1 contributes to the activation of the cyclin-dependent kinase 1 (CDK1).

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Mitotic entry: Bora takes Polo to Aurora, and gives them a hug

The EMBO Journal
Cell division involves the complete reorganization of the cellular architecture, requiring precise coordination of cellular processes in space and time, but how does this control system work at the atomic level?

Characterization of isolated late preantral and early antral equine ovarian follicles

Reproduction and Fertility
Understanding how to effectively isolate a large number of healthy follicles is essential for increasing success rates in ARTs, such as in vitro culture and cryopreservation.

Effect of different cryopreservation extenders added with antioxidants on semen quality and in vitro embryo production efficiency in cattle

Anais da Academia Brasileira de Ciências, 2021
To evaluate the addition of antioxidants in extenders on post-thaw bovine semen quality and in vitro embryo production efficiency. Six semen samples were collected from five Holstein bulls. In the experiment I, the samples were diluted with AndroMed® and

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
