Effect of route of administration of dinoprost tromethamine on plasma profiles of 13,14-dihydro-15-keto-prostaglandin F
Autor: M A, Mezera, M R, Lauber, A D, Beard, E M, Cabrera, M C, Wiltbank, P M, Fricke
Publikováno v: JDS communications. 2(6)
Lutalyse HighCon (dinoprost tromethamine; Zoetis) has been approved for use both intramuscularly and subcutaneously in lactating dairy cows, although the effect of route of administration on circulating 13,14-dihydro-15-keto-prostaglandin F

Differential actions of second messenger systems in the corpus luteum
Autor: M C Wiltbank, G D Niswender, M G Diskin
Publikováno v: Bioscientifica Proceedings.
Our current working hypothesis for the intracellular mechanism of action for LH and PGF-2 alpha is shown in Fig. 8. Luteinizing hormone appears to act primarily on the small luteal cell through the cAMP/protein kinase A effector system and thereby st

Investigation of mechanisms involved in regulation of progesterone catabolism using an overfed versus underfed ewe-lamb model
Autor: F C S Z, Mattos, A M O, Canavessi, M C, Wiltbank, M R, Bastos, A P, Lemes, G B, Mourão, I, Susin, L L, Coutinho, R, Sartori
Publikováno v: Journal of animal science. 95(12)
Alterations in progesterone (P4) catabolism due to high feed intake underlie some effects of nutrition on reproduction. Based on previous research, we hypothesized that high feed intake could potentially increase P4 catabolism, likely due to increase

Prostaglandin moieties that determine receptor binding specificity in the bovine corpus luteum
Autor: M. C. Wiltbank, Lori E. Anderson, M. K. Schultz
Publikováno v: Reproduction. 116:133-141
This study provided a pharmacological evaluation of prostaglandin binding to bovine luteal plasma membrane. It was found that [ 3 H]PGF 2α , [ 3 H]PGE 2 , [ 3 H]PGE 1 and [ 3 H]PGD 2 all bound with high affinity to luteal plasma membrane but had dif

Regulation of cytochrome P450scc synthesis and activity in the ovine corpus luteum
Autor: M C Wiltbank, Dean E. Hawkins, Gordon D. Niswenders, Carol J. Belfiore
Publikováno v: The Journal of Steroid Biochemistry and Molecular Biology. 51:283-290
The rate-limiting step in luteal biosynthesis of progesterone consists of cleavage of the side chain of cholesterol by mitochondrial cytochrome P450 side-chain cleavage enzyme (P450scc) to form pregnenolone. Luteal mRNA encoding P450scc, quantitated

Managing the dominant follicle in high-producing dairy cows
Autor: M C, Wiltbank, R, Sartori, J L M, Vasconcelos, A B, Nascimento, A H, Souza, A P, Cunha, A, Gumen, S, Sangsritavong, J N, Guenther, H, Lopez, J R, Pursley
Publikováno v: Society of Reproduction and Fertility supplement. 67
Reduced reproductive efficiency has been reported in high-producing dairy cows. Sources of reproductive inefficiency include decreased expression of estrus, increased diameter of the ovulatory follicle and reduced fertility when cows are inseminated

Steroidogenic enzyme activity after acute activation of protein kinase (PK) A and PKC in ovine small and large luteal cells
Autor: Carol J. Belfiore, M C Wiltbank, Gordon D. Niswender
Publikováno v: Molecular and Cellular Endocrinology. 97:1-7
Intracellular effector systems which utilize PKA and PKC can be pharmacologically activated by forskolin and phorbol 12-myristate 13-acetate (PMA) and appear to be important for regulation of steroidogenesis by cells of the corpus luteum. In this stu

PGE2 attenuates PGF2α-induced increases in free intracellular calcium in ovine large luteal cells
Autor: M C Wiltbank, Stanley B. Kater, G.J. Wiepz, H R Sawyer, Gordon D. Niswender
Publikováno v: Prostaglandins. 45:167-176
When ovine large luteal cells are placed in culture and exposed to PGF2 alpha, there is a rapid and sustained increase in the concentration of free intracellular calcium which is believed to play a major role in the luteolytic and cytotoxic effects o
