Roundup in the Reproduction of Crucian Carp (Carassius carassius): An In Vitro Effect on the Pituitary Gland and Ovary

Animals, 2022
Roundup, the most popular herbicide in global agriculture, is regarded as an endocrine disruptor causing alterations of important hormones at the hypothalamic−pituitary−gonadal axis as well as impairment of gametogenesis.

Freeze/thaw stress induces organelle remodeling and membrane recycling in cryopreserved human mature oocytes [PDF]

, 2016
Purpose: Our aim was to evaluate the ultrastructure of human metaphase II oocytes subjected to slow freezing and fixed after thawing at different intervals during post-thaw rehydration.

Germ Cell Responses to Stress: The Role of RNP Granules

Frontiers in Cell and Developmental Biology, 2019
The ability to respond to stress is critical to survival for animals. While stress responses have been studied at both organismal and cellular levels, less attention has been given to the effect of stress on the germ line. Effective germ line adaptations

Factors affecting the in vitro embryo production in buffalo (Bubalus bubalis): A review

Veterinární Medicína, 2023
Under natural and well-managed conditions, the buffalo has good reproductive and productive indices. However, in vitro embryo production (IVEP) has been used commercially to maximise the number of elite animals.

Combination of CNP, MT and FLI during IVM Significantly Improved the Quality and Development Abilities of Bovine Oocytes and IVF-Derived Embryos

Antioxidants, 2023
Oocyte maturation is a critical step in the completion of female gametogenesis in the ovary; thus, for subsequent fertilization and embryogenesis. Vitrification of embryo also has been shown to be closely associated with oocyte maturation. To improve the

Regulated mitochondrial DNA replication during oocyte maturation is essential for successful porcine embryonic development. [PDF]

, 2006
Cellular ATP is mainly generated through mitochondrial oxidative phosphorylation, which is dependent on mitochondrial DNA (mtDNA). We have previously demonstrated the importance of oocyte mtDNA for porcine and human fertilization.

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.

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.

Coexpression of rat P2X2 and P2X6 subunits in Xenopus oocytes. [PDF]

, 2000
Transcripts for P2X(2) and P2X(6) subunits are present in rat CNS and frequently colocalize in the same brainstem nuclei. When rat P2X(2) (rP2X(2)) and rat P2X(6) (rP2X(6)) receptors were expressed individually in Xenopus oocytes and studied under ...

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).
