Using molecular, biochemical, and cytological tools, we studied the nucleotide and the deduced amino acid sequence of PHI/VIP and the distribution of VIP/VPAC receptor system in the testis of the Italian wall lizard Podarcis sicula to evaluate the involvement of such a neuropeptide in the spermatogenesis control. We demonstrated that (1) Podarcis sicula VIP had a high identity with other vertebrate VIP sequences, (2) differently from mammals, VIP was synthesized directly in the testis, and (3) VIP and its receptor VPAC2 were widely distributed in germ and somatic cells, while the VPAC1R had a distribution limited to Leydig cells. Our results demonstrated that in Podarcis sicula the VIP sequence is highly preserved and that this neuropeptide is involved in lizard spermatogenesis and steroidogenesis. J. Exp.

Abstract

Using molecular, biochemical, and cytological tools, we studied the nucleotide and the deduced amino acid sequence of PHI/VIP and the distribution of VIP/VPAC receptor system in the testis of the Italian wall lizard Podarcis sicula to evaluate the involvement of such a neuropeptide in the spermatogenesis control. We demonstrated that (1) Podarcis sicula VIP had a high identity with other vertebrate VIP sequences, (2) differently from mammals, VIP was synthesized directly in the testis, and (3) VIP and its receptor VPAC2 were widely distributed in germ and somatic cells, while the VPAC1R had a distribution limited to Leydig cells. Our results demonstrated that in Podarcis sicula the VIP sequence is highly preserved and that this neuropeptide is involved in lizard spermatogenesis and steroidogenesis. J. Exp.
