Breakdown of choline-containing phospholipids in rat brain during severe weight loss.
2002
Recent investigations in human anorectic patients indicated changes of brain choline metabolism. We used starved rats to investigate possible changes of brain choline metabolites during severe weight loss. Reductions of body weight by 15, 30 and 45% resulted in significant decreases of cerebral phosphatidylcholine and sphingomyelin levels. Concomitantly, the brain tissue content of glycerophosphocholine was increased while phosphocholine and free choline were unchanged. We conclude that severe weight loss is accompanied by phospholipase activation and breakdown of choline-containing phospholipids in the brain.
Systematic screening for mutations in the promoter and the coding region of the 5-HT1A gene.
1995
In the present study we sought to identify genetic variation in the 5-HT{sub 1A} receptor gene which through alteration of protein function or level of expression might contribute to the genetic predisposition to neuropsychiatric diseases. Genomic DNA samples from 159 unrelated subjects (including 45 schizophrenic, 46 bipolar affective, and 43 patients with Tourette`s syndrome, as well as 25 healthy controls) were investigated by single-strand conformation analysis. Overlapping PCR (polymerase chain reaction) fragments covered the whole coding sequence as well as the 5{prime} untranslated region of the 5-HT{sub 1A} gene. The region upstream to the coding sequence we investigated contains a …
