abstractText | Fyn-deficient mice were produced by inserting the beta-galactosidase gene (lacZ) into the fyn gene locus. The homozygously Fyn kinase-deficient (fynz/fynz) mice exhibited stronger light aversion in the light-dark choice test and higher fear-response scores in the novelty preference and passive avoidance tests than did the heterozygously Fyn-deficient (+/fynz) mice. These results indicate that fynz/fynz mice are hyperresponsive to fear-inducing stimuli. |
