In mammals, sex determination is genetically controlled. The SRY gene, located on Y chromosome, functions as the dominant genetic switch for testis development. The SRY gene is specifically expressed in a subpopulation of somatic cells (pre-Sertoli cells) of the developing urogenital ridge for a brief period during gonadal differentiation. Despite this(More)
To study the process of mammalian sex determination and in particular to further understand the mechanisms of transcriptional regulation of the SRY gene, we have isolated a 4.5-kilobase (kb) pig SRY 5' flanking sequence. To facilitate the in vitro analysis of these sequences, we have generated a porcine genital ridge (PGR) cell line (9E11) that expresses(More)
Myotonic dystrophy type 1 (DM1) and type II (DM2) are dominantly inherited multisystemic disorders. DM1 is triggered by the pathological expansion of a (CTG)(n) triplet repeat in the DMPK gene, whereas a (CCTG)(n) tetranucleotide repeat expansion in the ZNF9 gene causes DM2. Both forms of the disease share several features, even though the causative(More)
Steroidogenic acute regulatory protein (StAR) is an essential cholesterol transporter in steroidogenic tissues. Hormone-induced StAR expression is regulated through the cAMP-dependent pathway involving activation of protein kinase A (PKA). The StAR promoter contains several conserved DNA regulatory elements. These include binding sites for steroidogenic(More)
