Sex hormone signalling is key in the understanding of adipose tissue metabolism during pregnancy. Sex hormones play an important role in adipose tissue metabolism by activating specific receptors that alter several steps of lipolysis and lipogenesis. We analyze steroid receptor mRNA levels in...
The primary source of 17beta-estradiol (E2) in the male is the testis, which expresses the enzyme complex aromatase that is involved in E2 biosynthesis. However, recent evidences suggest that the epididymis is also capable of E2 biosynthesis. Our results demonstrate the presence of cytochrome...
Previous studies have shown that insulin augments GnRH-stimulated LH synthesis and release from primary gonadotrophs. In this study, regulation of LHβ gene expression by GnRH and insulin was examined in LβT2 cells. Endogenous LHβ mRNA is stimulated 2.4-fold by insulin alone, 2.6-fold by GnRH...
17α-Hydroxylase deficiency is a rare disease caused by mutation of the CYP17 gene, resulting in hypertension, hypokalemia, female sexual infantilism or male pseudohermaphroditism, low blood cortisol and low plasma renin activity. Herein, we report a female Taiwanese with 17α-hydroxylase...
This is the first study evaluating whether oocyte development and fertilization competence are related to intrafollicular concentration of cholesterol, meiosis-activating sterols and progesterone, after human chorionic gonadotrophin (HCG) administration of women with polycystic ovarian syndrome...
Multiple endocrine neoplasia type 1 (MEN1) is caused by autosomal dominantly inherited mutations in the MEN1 gene. Here, we report 25 MEN1 mutations – of which 12 are novel – found in 36 Danish families with MEN1 or variant MEN1 disease. Furthermore, one FIHP family was found to have an...
In birds, rhythmic changes in pineal serotonin N -acetyltransferase (arylalkylamine N -acetyltransferase, Aanat ) transcripts are controlled by an oscillator located in the pinealocytes themselves which is comprised by clock genes. Our previous data indicated a temporal association between the...
The proximal promoter of the human growth hormone gene (GH1) is highly polymorphic. We tested if promoter haplotypes differing at possibly functional sites, namely −278T/G (in the NF1 binding site), −75A/G (in the proximal Pit-1 binding site) and −57G/T (in the VDR binding site), induced a...
