Phenotypes Associated with This Genotype

Genotype
MGI:7763625

• Allelic Composition: Kansl1^em1.1Cya/Kansl1⁺
• Genetic Background: B6(FVB)-Kansl1^em1.1Cya

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

behavior/neurological

impaired long-term object recognition memory ( J:327464 )

• mice show a memory impairment during the object recognition task

• the impairment of memory is significantly restored by 13-cis retinoic acid administration in novel object recognition tests

impaired spatial learning ( J:327464 )

• in the Morris water maze, although mice swim as fast as wild-type mice, their escape time is longer after 4 days of training, indicating impaired spatial learning

• 13-cis retinoic acid treatment shortens the escape latencies in Morris water maze tasks

cardiovascular system

decreased cardiac muscle contractility ( J:327464 )

• mice exhibit decreased ejection fraction and fractional shortening indicating impaired cardiac function

abnormal heart echocardiography feature ( J:327464 )

• echocardiogram shows decreased ejection fraction and fractional shortening

cellular

abnormal autophagy ( J:327464 )

• murine embryonic fibroblasts (MEFs) exhibit autophagic defects

• an excess of autophagosomes is seen in the hippocampus and heart tissues, indicating disruption of autophagic flux in the hippocampus and heart

oxidative stress ( J:327464 )

• reactive oxygen species (ROS) levels are increased in hippocampus and heart

homeostasis/metabolism

abnormal autophagy ( J:327464 )

• murine embryonic fibroblasts (MEFs) exhibit autophagic defects

• an excess of autophagosomes is seen in the hippocampus and heart tissues, indicating disruption of autophagic flux in the hippocampus and heart

muscle

decreased cardiac muscle contractility ( J:327464 )

• mice exhibit decreased ejection fraction and fractional shortening indicating impaired cardiac function

nervous system

decreased dendritic spine density ( J:327464 )

• the hippocampus CA1 region shows a reduction in spine density

• the reduction in spine density is rescued by treatment with 13-cis retinoic acid for 1 month

• however, no neuronal loss is seen in the hippocampus
