    Abstract:
    Congenic mice obtained by genome fragments transfer from one strain to another are a potent tool for studies of the molecular mechanisms of behavioral mutations. The 59-70 cM fragment of chromosome 13 containing the locus determining predisposition to freezing reaction (catalepsy) and the gene encoding 5-HT(1A) receptor were transferred from cataleptic CBA/Lac mice into the genome of catalepsy-resistant AKR/J mice. The impact of this fragment for the severity of catalepsy and expression of genes encoding tryptophane hydroxylase-2, serotonin transporter, and 5-HT(1A) receptor was studied. Half of mice of the resultant congenic AKR.CBA-D13Mit76 strain exhibited pronounced catalepsy, similarly to donor CBA animals. The expression of 5-HT(1A) receptor gene in the midbrain of AKR animals was significantly higher than in CBA. The level of 5-HT(1A) receptor mRNA in AKR.CBA-D13Mit76 animals was significantly higher than in the donor strain. Mice of parental AKR and CBA strains did not differ from each other and from AKR.CBA-D13Mit76 animals by the levels of tryptophane hydroxylase-2 and serotonin transporter genes mRNA. These data prove the location of catalepsy regulating gene in the distal fragment of chromosome 13. The recipient strain genome enhanced the expression of 5-HT(1A) receptor gene in the brain without modulating the expression of catalepsy gene.
