Effects of luteinizing hormone on glucose metabolism in cumulus-enclosed bovine oocytes matured in vitro

Autor: K A Zuelke, B G Brackett

Publikováno v: Endocrinology. 131:2690-2696

The effects of LH on glucose metabolism within cumulus cell-enclosed bovine oocytes were determined. Cumulus cell-enclosed bovine oocytes were matured in vitro (IVM) in control medium alone or supplemented with LH, FSH, or TSH, then individually assa

Conceptus development during blastocyst elongation in lines of pigs selected for increased uterine capacity or ovulation rate

Autor: J R, Miles, B A, Freking, L A, Blomberg, J L, Vallet, K A, Zuelke

Publikováno v: Journal of animal science. 86(9)

Lines of pigs selected for increased uterine capacity have improved conceptus survival, whereas pigs selected for increased ovulation rate have decreased conceptus survival relative to an unselected control line. The objective of this study was to ev

In vitro development and nutrient uptake by embryos derived from oocytes of pre-pubertal and adult cows

Autor: T E, Steeves, D K, Gardner, K A, Zuelke, T S, Squires, R C, Fry

Publikováno v: Molecular reproduction and development. 54(1)

The present study compared the developmental potential and uptake of nutrients by embryos from pre-pubertal and adult cows. Oocytes retrieved from ovaries of 5 to 7 month old calves and adult cows were matured and fertilized in vitro. Embryos were cu

Glutathione oxidation is associated with altered microtubule function and disrupted fertilization in mature hamster oocytes

Autor: K A, Zuelke, D P, Jones, S D, Perreault

Publikováno v: Biology of reproduction. 57(6)

We hypothesized that depletion of glutathione (GSH) with diamide, a relatively specific GSH oxidant, may alter the meiotic spindle apparatus in mature hamster oocytes. Immunofluorescent analysis of oocytes exposed to diamide for 1.5 or 3 h revealed t

Increased glutamine metabolism in bovine cumulus cell-enclosed and denuded oocytes after in vitro maturation with luteinizing hormone

Autor: K A, Zuelke, B G, Brackett

Publikováno v: Biology of reproduction. 48(4)

The effects of LH on tricarboxylic acid (TCA) cycle activity within denuded and cumulus cell-enclosed bovine oocytes were investigated by measuring the metabolism of L-[14C(U)]glutamine and [2-14C]pyruvate to 14CO2 after in vitro maturation (IVM) wit

In vitro fertilization of goat oocytes

Autor: A I, Younis, K A, Zuelke, K M, Harper, M A, Oliveira, B G, Brackett

Publikováno v: Biology of reproduction. 44(6)

Experiments were carried out to achieve fertilization (IVF) and initial embryonic development of goat oocytes in vitro. Oocyte/cumulus complexes were recovered from large follicles (greater than 7 mm) of hormonally treated doses and from 1-6-mm folli
