| N | normal phenotype |
|
• reduced numbers of homozygotes relative to expected when tested after birth
|
|
• 42% are initially runted but attain normal size by 6 weeks of age
|
|
• density of dendritic spines significantly reduced (by about 20%)
|
|
• density of dendritic spines of the apical dendrites of CA1 pyramidal neurons is about 40% higher between 60 and 80 micrometers from the cell body
• neuron morphology is otherwise normal
|
|
• 150 plulse trains of 5 Hz stimulations induced a more than twofold increase in long term potentiation than in wildtype
(J:98903)
|
|
• at interpulse intervals of 20, 50,100, and 200 ms
in CA1 pyramidal cells
|
|
• slower learning in a series of water maze tests
(J:77693)
• homozygotes learn little in the spatial water maze test regardless of the amount of training received
(J:98903)
|
|
• fail to develop thermal hyperalgesia and mechanical allodynia after chronic constriction injury of the sciatic nerve
|
|
• cold allodynia severely attenuated relative to controls after chronic constriction injury of the sciatic nerve
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
 |
• crosses of heterozygous Dlg3 and Dlg4 mice produce no double homozygotes; double mutants die perinatally with none surviving past day 3 postnatal
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
|
• crosses of heterozygous Dlg3 and Dlg4 mice produce a very low proportion of Dlg3tm1Grnt/+, Dlg4-null female mice
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• 150 plulse trains of 5 Hz stimulations induced a more than twofold increase in long term potentiation (LTP) than in wildtype, which was similar to the LTP seen in single homozygous Dlgh4 mice
|
|
|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
 |
• no Dlg3tm1Grnt/y, Dlg4-null male mice mice are produced by crosses of heterozygous Dlg3 and Dlg4 mice; double mutants die perinatally
