Vaillant S, Guemene D, Dorizzi M, Pieau C, Richard-Mercier N, Brillard J
Mol Reprod Dev . 2003 Jul; 65(4):420-8. PMID: 12840815
The objectives of this work were to determine whether or not plasma levels of testosterone and estradiol reflect the various grades of sex reversal in genetic female chickens treated with...

Vaillant S, Dorizzi M, Pieau C, Richard-Mercier N
J Exp Zool . 2001 Dec; 290(7):727-40. PMID: 11748621
Aromatase inhibitors administered before sexual differentiation of the gonads can induce sex reversal in female chickens. To analyze the process of sex reversal, we have followed for several months the...

Vaillant S, Magre S, Dorizzi M, Pieau C, Richard-Mercier N
Dev Dyn . 2001 Oct; 222(2):228-37. PMID: 11668600
Aromatase inhibitors administered prior to histological signs of gonadal sex differentiation can induce sex reversal of genetic female chickens. Under the effects of Fadrozole (CGS 16949A), a nonsteroidal aromatase inhibitor,...

Belaid B, Richard-Mercier N, Pieau C, Dorizzi M
J Exp Zool . 2001 Sep; 290(5):490-7. PMID: 11555856
In the European pond turtle (Emys orbicularis), gonadal sex differentiation is temperature-dependent. The temperature sensitive period (TSP) of gonadogenesis lies between stages 16 and 22 of embryonic development. Previous studies...

Pieau C, Dorizzi M, Richard-Mercier N
EXS . 2001 Apr; (91):117-41. PMID: 11301596
In many reptile species, sexual differentiation of gonads is sensitive to temperature (temperature-dependent sex determination, TSD) during a critical period of embryonic development (thermosensitive period, TSP). Experiments carried out with...

Pieau C, Dorizzi M, Richard-Mercier N
Cell Mol Life Sci . 1999 Jul; 55(6-7):887-900. PMID: 10412370
In many reptile species, sexual differentiation of gonads is sensitive to temperature during a critical period of embryonic development (thermosensitive period, TSP). Experiments carried out with different models among which...

Pieau C, Dorizzi M, Richard-Mercier N, Desvages G
J Exp Zool . 1998 Jul; 281(5):400-8. PMID: 9662827
Emys orbicularis is a freshwater turtle with temperature-dependent sex determination. Estrogens play a major role in gonadal differentiation; when they are produced at high levels during the thermosensitive period (TSP),...

Dorizzi M, Richard-Mercier N, Pieau C
Differentiation . 1996 Jul; 60(4):193-201. PMID: 8765049
Emys orbicularis is a turtle with temperature-dependent sex determination. The thermosensitive period (TSP) lies between embryonic stages 16 and 22. Gonadal differentiation begins during this period involving oestrogens. Treatment with...

Richard-Mercier N, Dorizzi M, Desvages G, Girondot M, Pieau C
Gen Comp Endocrinol . 1995 Dec; 100(3):314-26. PMID: 8775058
In embryos of Emys orbicularis, the sexual differentiation of gonads is influenced by the incubation temperature of eggs. Estrogens administered during the thermosensitive period result in the feminization of gonads...

Richard-Mercier N, Thomas-Orillard M, Moriniere M, Porcheron P, Soyez D, Fellous M
Arch Insect Biochem Physiol . 1992 Jan; 21(2):77-89. PMID: 1457805
From a medium in which Daudi cells had been grown, we isolated by HPLC a protein that caused ovarian abnormalities in adult females of Drosophila melanogaster when injected into preblastoderm...
