Responsiveness of bovine cumulus-oocyte-complexes (COC) to porcine and recombinant human FSH, and the effect of COC quality on gonadotropin receptor and Cx43 marker gene mRNAs during maturation in vitro [PDF]

, 2003
Substantially less development to the blastocyst stage occurs in vitro than in vivo and this may be due to deficiencies in oocyte competence. Although a large proportion of bovine oocytes undergo spontaneous nuclear maturation, less is known about ...

Superovulatory response of water buffalo (Bubalus bubalis) to gonadotrophins out of the breeding season

Italian Journal of Animal Science, 2010
Ten adult cyclic female buffaloes (5 normo-karyotype and 5 hybrids) were treated with a conventional superovulation protocol following 2 luteolytic doses (25 mg, i.m.) of PGF2α 11 days apart (days -11 and 0).

Inflammation is a key contributor to ovarian cancer cell seeding. [PDF]

, 2018
The incidence of ovarian cancer dramatically increases in early menopause but the factors contributing to cancer onset are unclear. Most ovarian cancers originate in the fallopian tube with subsequent implantation of malignant cells into the ovary ...

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Multiple superovulations in N'Dama heifers

Tropical Animal Health and Production, 1990
Five N'Dama heifers were superovulated with follicle stimulating hormone (FSH-P or Folltropin) a total of six times each. The superovulations were carried out between ongoing experimental Trypanosoma congolense infections. Twenty-four (80%) of the 30 superovulations had a good ovarian response with 21 (70%) producing an average of 2.7 +/- 0.4 (mean +/-

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

Advanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9

Animal Models and Experimental Medicine, EarlyView.
We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.

Study of anti-Müllerian hormone in predicting embryo productivity of donor cows [PDF]

BIO Web of Conferences
The study included a study of biochemical parameters at different stages of the productive cycle. Ultrasound images at different stages of the cycle, and during superovulation were analyzed.

Neonatal exposure to xenoestrogens impairs the ovarian response to gonadotropin treatment in lambs [PDF]

, 2015
Bisphenol A (BPA) and diethylstilbestrol (DES) are xenoestrogens which have been associated with altered effects on reproduction. We hypothesized that neonatal xenoestrogen exposure affects the ovarian functionality in lambs.

Microtubule Inner Protein CFAP77 Contributes to Sperm Motility and Male Fertility in Mice

Andrology, EarlyView.
ABSTRACT Background Sperm motility is essential for male fertility, and its regulation is dependent on the structural integrity of the axoneme. The axoneme consists of a conserved “9+2” microtubule arrangement and is supported by microtubule inner proteins. However, the functional significance of many microtubule inner proteins remains unclear.
