Identification of multiple genetic loci in the mouse controlling immobility time in the tail suspension and forced swimming tests.
Depression is one of the most famous psychiatric disorders in humans in all over the countries and considered a complex neurobehavioral trait and difficult to identify causal genes. Tail suspension test (TST) and forced swimming test (FST) are widely used for assessing depression-like behavior and antidepressant activity in mice. A variety of antidepressant agents are known to reduce immobility time in both TST and FST. To identify genetic determinants of immobility duration in both tests, we analyzed 101 F2 mice from an intercross between C57BL/6 and DBA/2 strains. Quantitative trait locus (QTL) mapping using 106 microsatellite markers revealed three loci (two significant and one suggestive) and five suggestive loci controlling immobility time in the TST and FST, respectively. Results of QTL analysis suggest a broad description of the genetic architecture underlying depression, providing underpinnings for identifying novel molecular targets for antidepressants to clear the complex genetic mechanisms of depressive disorders.
期刊介绍：
The Japanese Journal of Veterinary Research (JJVR) quarterly publishes peer-reviewed articles on all aspects of veterinary science. JJVR was originally published as a “University Journal” of veterinary science at Hokkaido University from more than 60 years ago. Currently, JJVR, is Japan’s leading scientific veterinary journal, and provides valuable information for the development of veterinary science by welcoming contributions from researchers worldwide.
JJVR offers online submission for Regular Papers, Short Communications, and Review Articles that are unpublished and not being considered for publication elsewhere. Research areas include:
Anatomy, Physiology, Biochemistry, Pharmacology, Microbiology, Infectious diseases, Parasitology, Laboratory Animal Science and Medicine, Internal Medicine, Surgery, Pathology, Theriogenology, Molecular Medicine, Public Health, Radiation Biology, Toxicology, Wildlife Biology and Medicine, Veterinary Hygiene, The other fields related to veterinary science.
