Title

Female Flinders Sensitive Line rats show estrous cycle-independent depression-like behavior and altered tryptophan metabolism

Overall design

The aim of this study was to investigate 13 kynurenine and serotonin metabolites in female Flinders Sensitive Line (FSL) rats, a genetic rat model of depression. FSL rats and controls (Flinders Resistant Line rats), 12-20 weeks old, were subject to the forced swim test (FST), a commonly used measure of depression-like behavior. Open field was used to evaluate locomotor ability and agoraphobia. Tryptophan, kynurenine, 3-hydroxykynurenin, 5-hydroxytryptophan, 5-HT, nicotinamide, anthranilate, quinolinic acid and kynurenate were measured and analyzed for both brain and plasma using LC-MS. In Experiment 1, the female rats were divided into the following 2 groups: (1) Female FSL group (n = 31), (2) Female FRL group (n = 28). Brain and plasma tissues were collected for LC-MS analysis. In Experiment 2, the male rats were divided into the following 2 groups: (1) Male FSL group (n = 6), (2) Male FRL group (n = 6).
