Disturbances in central serotonin (5-HT) function may have a role in impulsive aggression in patients with a wide range of psychiatric diagnoses. The underlying mechanism, however, remains unknown. There are several naturally occurring mutations in the 5-HT signaling pathway that may underlie differences in 5-HT function and responsivity to drugs that(More)
RNA encoding the rat serotonin 5-HT2C receptor undergoes editing whereby one to four adenosines are converted to inosines. This conversion can change up to three codons out of a stretch of five in the second intracellular loop of the receptor. RNA editing of the rat 5-HT2C receptor that changes all three codons was shown previously to alter intracellular(More)
Termination of transcription by RNA polymerase II usually requires the presence of a functional poly(A) site. How the poly(A) site signals its presence to the polymerase is unknown. All models assume that the signal is generated after the poly(A) site has been extruded from the polymerase, but this has never been tested experimentally. It is also widely(More)
Many modern models of receptor-G protein function assume that there is a direct relationship between high-affinity agonist binding and efficacy. The validity of this assumption has been recently questioned for the serotonin 5-HT2A receptor. We examined the intrinsic activities of various ligands in activating phosphoinositide hydrolysis and measured their(More)
The incidence of Congenital Adrenal Hyperplasia (CAH) in some Asian countries is far higher than in Australia, (eg 1:6000 as per the Filipino Newborn Screening Program). For many families in low and middle-income countries in Asia resources are limited, affordable and reliable access to essential medicines is problematic, and families living remotely are(More)
Aims To describe the clinical presentation and sequelae of undiagnosed congenital adrenal hyperplasia (CAH). A 5-year-old boy presented with penis and testicular enlargement for 1 year. The past medical history had no severe vomiting or failure to thrive. His height was 120 cm (> 95th percentile). His penis was 7 cm and asymmetric testicles. Scrotal(More)
