Cyclic AMP Affects Oocyte Maturation and Embryo Development in Prepubertal and Adult Cattle
Sandra Milena Bernal-Ulloa,Julia Heinzmann,Doris Herrmann,Klaus-Gerd Hadeler,Patrick Aldag,Sylke Winkler,Dorit Pache,Ulrich Baulain,Andrea Lucas-Hahn,Heiner Niemann +9 more
TL;DR: Data indicate that cAMP regulates IVM in prepubertal and adult oocytes in a similar manner, with impact on the establishment of epigenetic marks and acquisition of full developmental competency.
Extended in vitro maturation affects gene expression and DNA methylation in bovine oocytes
Julia Heinzmann,Felix Mattern,Patrick Aldag,Sandra Milena Bernal-Ulloa,Tamara Schneider,Thomas Haaf,Heiner Niemann +6 more
TL;DR: The results indicate that extended IVM leads to ageing-like alterations and demonstrate that epigenetic mechanisms are critically involved in ageing of bovine oocytes, which warrants further studies into epigenetic mechanism involved in Ageing of female germ cells, including humans.
Characterization of Differentially Methylated Regions in 3 Bovine Imprinted Genes: A Model for Studying Human Germ-Cell and Embryo Development
TL;DR: The identified IGF2-H19 ICR and the developed quantitative methylation assays may prove useful for further studies on the relationship between ARTs and imprinting defects in the bovine model.
Effects of long-term dietary supplementation with conjugated linoleic acid on bovine oocyte lipid profile
A.F. González-Serrano,Christina R. Ferreira,Valentina Pirro,Andrea Lucas-Hahn,Julia Heinzmann,Klaus-Gerd Hadeler,Ulrich Baulain,Patrick Aldag,Ulrich Meyer,Marion Piechotta,Gerhard Jahreis,Sven Dänicke,R. Graham Cooks,Heiner Niemann +13 more
TL;DR: Results show that rumen-protected fatty-acid supplementation affects oocyte lipid content and may pave the way for the establishment of a large-animal model for studies towards a better understanding of reproductive disorders associated with nutritional impairments.

Rapid, untargeted lipid determination in individual bovine oocytes and pre-implantation embryos by high-resolution desorption electrospray ionization mass spectrometry
A.F. González-Serrano,Christina R. Ferreira,Valentina Pirro,Livia S. Eberlin,Julia Heinzmann,Andrea Lucas-Hahn,Heiner Niemann,R. G. Cooks +7 more
TL;DR: The use of DESI-MS for the sensitive analysis of TAG in individual bovine oocytes and embryos and the creation of profiles of FA, PL, and TAG species in the same sample by DESi-MS is reported.
