| Research Abstract |
1. APC is required for the activity of AMPA receptors through facilitating the clustering of PSD-95 and these receptors at the post-synaptic spine.
2. The APC localization in cultured neurons alters depending on their development and differentiation.
3. Microtubule bundling-activity of APC is stimulated by its interaction with PSD-95.
4. The kidneys and ureters of Dlghl-knockout mice were hypoplastic and the lower ends of the ureters were ectopic.
5. The vagina and seminal vesicle were absent in the Dlghl-knockout mice. These phenotypes seem to be much alike to those in the human congenital disease Mayer-Rokitansky-Kuster-Hauser Syndrome.
6. ICAT-knockout mice showed multiple developmental defects. Most of the ICAT(-/-) embryos exhibited a truncation of the rostral head.
7. Some of the ICAT(-/-) embryos lacked kidneys. The defect in kidney development was found to be caused by arrest of the ureteric bud-branching during nephrogenesis.
