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)
Differentiation of muscle cells is characterized morphologically by the acquisition of contractile filaments and characteristic shape changes, and on the molecular level by induction of the expression of several genes, including those for the muscle-specific alpha-actin isoforms. IFN-gamma is an inhibitor of proliferation for several cells, including(More)
In CHO cells transfected with the rat dopamine D2 receptor (long isoform), administration of dopamine per se elicited a concentration-dependent increase in arachidonic acid (AA) release. The maximal effect was 197% of controls (EC50=25 nM). The partial D2 receptor agonist, (-)-(3-hydroxyphenyl)-N-n-propylpiperidine [(-)-3-PPP], also induced AA release, but(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)
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)
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)
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)
We have earlier demonstrated that dopamine stimulates the liberation of the prostaglandin E(2) (PGE(2)) precursor, arachidonic acid, in Chinese hamster ovary cells transfected with the rat dopamine D(2) receptor (long isoform), also without concomitant administration of a Ca(2+)-releasing agent [Nilsson et al., Br J Pharmacol 1998;124:1651-8]. In the(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)
