To elucidate the possible role of genetic variation in androgen receptor (AR), estrogen receptor alpha (ER alpha), and ER beta on serum androgen levels in premenopausal women, the CAG repeat polymorphism of the AR gene, the TA repeat polymorphism of the ER alpha gene, and the CA repeat polymorphism of the ER beta gene were studied in a population-based(More)
Muscle cell differentiation is characterized by the synthesis ofcontractile proteins, their organization in specialized structures, the synthesis of enzymes ofspecific metabolic pathways, and the inhibition ofcell proliferation (1). Activation ofmuscle-specific gene expression is coupled to withdrawal from the cell cycle; therefore, much interest has been(More)
Several studies have reported an association between anxiety-related personality traits and a promoter polymorphism in the human serotonin transporter (5-HTT) gene (5-HTT gene-linked polymorphic region, 5-HTTLPR). In the present study, a population of 251 subjects was assessed with the Karolinska Scales of Personality (KSP) and genotyped both for the(More)
Transsexualism is characterised by lifelong discomfort with the assigned sex and a strong identification with the opposite sex. The cause of transsexualism is unknown, but it has been suggested that an aberration in the early sexual differentiation of various brain structures may be involved. Animal experiments have revealed that the sexual differentiation(More)
Our earlier observation that the antipsychotic drug haloperidol in the absence of dopamine increases cAMP formation and prolactin release in two prolactin-producing cell lines expressing rat dopamine D2 receptors (GH3, GH4ZR7), but not in similar cells devoid of D2 receptors (GH4C1), prompted us to suggest that haloperidol may act as an inverse (or(More)
Receptors of the 5-HT2C subtype are assumed to be involved in the influence of serotonin on food intake. A polymorphism in the coding region of the gene for this receptor, resulting in a cysteine to serine substitution, has been reported. Fifty-seven somatically healthy teenage girls displaying weight loss and 91 normal-weight girls of the same age, all(More)
Studies of hormone therapy (HT) and cognition have yielded conflicting results. The aim of this observational study was to examine the effect of estradiol, via serum verified HT (estradiol, estriol, progesterone) and endogenous estradiol, on 108 healthy postmenopausal women's cognitive performance. The results demonstrated that the 43 HT-users performed at(More)
T he dopamine D 3 receptor is a member of the D2 family of dopamine receptors. Several investigators have suggested that D 3 receptors are involved in the regulation of locomotion, 1 in the pathophysiology of schizophrenia, 2 and in drug abuse. 3 Dopamine enhances basal and stimulus evoked release of arachidonic acid, as well as the production of one of its(More)
The abilities of dopamine (DA) and the partial DA D2 receptor agonist (-)-(3-hydroxyphenyl)-N-n-propylpiperidine, (-)-3-PPP, to suppress prolactin (PRL) release induced by any of five different PRL secretagogues in GH4C1 cells transfected with the human D2 receptor (short isoform) were investigated. Whereas DA reduced the response to all five secretagogues.(More)
