BACKGROUND To better understand the molecular programs of normal and abnormal genital development, clear-cut definition of androgen-dependent gene expression patterns, without the influence of genotype (46, XX vs. 46, XY), is warranted. Previously, we have identified global gene expression profiles in genital-derived fibroblasts that differ between 46, XY(More)
Adult subjects with growth hormone (GH) deficiency (GHD) are known to have reduced life expectancy due to increased cardiovascular and cerebrovascular events. In adults, these events are associated with elevated circulating concentrations of asymmetric dimethylarginine (ADMA) which is an endogenous inhibitor of l-arginine (Arg)-derived nitric oxide (NO).(More)
BACKGROUND Male pseudohermaphroditism, or Leydig cell hypoplasia (LCH), is an autosomal recessive disorder in individuals with a 46,XY karyotype, characterized by a predominantly female phenotype, a blind-ending vagina, absence of breast development, primary amenorrhea, and the presence of testicular structures. It is caused by mutations in the luteinizing(More)
OBJECTIVE Leptin is known to play an important role in pubertal development in humans, probably acting as one permissive factor for the onset of puberty. Leptin serum concentrations change during pubertal development and an initial increase before the onset of puberty has been reported. The underlying mechanism for this increase in leptin levels is unknown.(More)
BACKGROUND Gender appears to be determined by independent programs controlled by the sex-chromosomes and by androgen-dependent programming during embryonic development. To enable experimental dissection of these components in the human, we performed genome-wide profiling of the transcriptomes of peripheral blood mononuclear cells (PBMC) in patients with(More)
The luteinizing hormone/chorionic gonadotropin receptor (LHCGR) is essential for normal male sex differentiation. Recently, the additional primate-specific exon 6A of the LHCGR was discovered and it was shown to act as regulatory element at the transcriptional level. Compound heterozygous mutations in exon 6A (c.580 A>G) and exon 11 (c.1244T>C) were(More)
