In previous minireviews in this journal, we discussed work on induction of tetrahydrobiopterin biosynthesis by cytokines and its significance for nitric oxide (NO) production of intact cells as well as functions of H4-biopterin identified at this time for NO synthases (Proc Soc Exp Biol Med 203: 1-12, 1993; Proc Soc Exp Biol Med 219: 171-182, 1998).

|
In rabbit blastocysts, embryonic IGF1 and IGF2 are specifically strong in the embryoblast (ICM).
|

|
Signalling of IGFs and insulin in blastocysts follows the classical pathway with Erk1/2 and Akt kinase activation.

Exp IDD was induced in female rabbits by alloxan treatment prior to mating.

|
In pregnant females, hepatic IGF1 expression and IGF1 serum levels were decreased while IGF1 and IGF2 were increased in endometrium.
|
7 |

|
In cultured control blastocysts supplemented with IGF1 or insulin in vitro for 1 or 12 h, IGF1 and insulin receptors as well as IGF1 and IGF2 were downregulated.

|
In cultured T1D blastocysts activation of Akt and Erk1/2 was impaired with lower amounts of total Akt and Erk1/2 protein and a reduced phosphorylation capacity after IGF1 supplementation.

|
Both, the endometrium and the blastocyst produce more IGF1 and IGF2.
|

|
The increased endogenous IGF1 and IGF2 expression by the blastocyst compensates for the loss of systemic insulin and IGF.
