Journal ArticleDOI
Large-scale transcriptional analysis of bovine embryo biopsies in relation to pregnancy success after transfer to recipients.
Ashraf M. El-Sayed,Michael Hoelker,Franca Rings,Dessie Salilew,Danyel Jennen,Ernst Tholen,Marc-André Sirard,Karl Schellander,Dawit Tesfaye +8 more
TL;DR: Direct candidates of blastocyst-specific genes which may play an important role in determining the fate of the embryo after transfer are generated.
Journal ArticleDOI
Exosomal and Non-Exosomal Transport of Extra-Cellular microRNAs in Follicular Fluid: Implications for Bovine Oocyte Developmental Competence.
Md. Mahmodul Hasan Sohel,Michael Hoelker,Sina Seifi Noferesti,Dessie Salilew-Wondim,Ernst Tholen,Christian Looft,Franca Rings,Muhammad Jasim Uddin,Thomas E. Spencer,Karl Schellander,Dawit Tesfaye +10 more
TL;DR: The presence of exosome or non-exosome mediated transfer of miRNA in the bovine follicular fluid, and oocyte growth dependent variation in extra-cellular miRNA signatures in the follicular environment is demonstrated for the first time.
Journal ArticleDOI
Identification and expression profiling of microRNAs during bovine oocyte maturation using heterologous approach.
Dawit Tesfaye,Dagnachew Worku,Franca Rings,Chirawath Phatsara,Ernst Tholen,Karl Schellander,Michael Hoelker +6 more
TL;DR: This work investigated the expression of miRNAs in immature and in vitro matured bovine oocytes, using heterologous miRNA array platform and revealed the differential expression of 59 miRNAAs, of which 31 and 28 mi RNAs were found to be preferentially expressed in mature and matured oocyte, respectively.
Journal ArticleDOI
Identification and characterization of miRNAs expressed in the bovine ovary
M. M. Hossain,Nasser Ghanem,Michael Hoelker,Franca Rings,Chirawath Phatsara,Ernst Tholen,Karl Schellander,Dawit Tesfaye +7 more
TL;DR: The presence of miRNAs in the bovine ovary is suggested to elucidate their potential role in regulating diverse molecular and physiological pathways underlying the ovarian functionality.
Journal ArticleDOI
Molecular Mechanisms and Pathways Involved in Bovine Embryonic Genome Activation and Their Regulation by Alternative In Vivo and In Vitro Culture Conditions
Ahmed Gad,Ahmed Gad,Michael Hoelker,Urban Besenfelder,Vitezslav Havlicek,U Cinar,Franca Rings,Eva Held,Isabelle Dufort,Marc-André Sirard,Karl Schellander,Dawit Tesfaye +11 more
TL;DR: Examination of alternative in vivo and in vitro culture conditions at the time of major embryonic genome activation (EGA) on the development and transcriptome profile of bovine blastocysts showed that changing culture conditions from in vivo to in vitro or vice versa had no effect on the developmental rates; however, in vitro conditions during that time critically influenced the transcriptome of the blastocyst produced.
