Promoter analysis of the gene encoding GDNF in murine Sertoli cells.

•First characterization of murine GDNF promoter region in Sertoli cells.•Identification of the transcriptional start sites.•In-silico analysis of evolutionarily conserved putative transcription factor-binding sites.•Performed progressive promoterdeletions.•Identification of three CRE sites involved in basal and cAMP-induced expression.
