mortality/aging
• tamoxifen treatment at E9.5, but not at E10.5, results in death at birth
|
nervous system
• when tamoxifen treated at E10.5, at P2 proliferation is similar in the anterior and central lobules, unlike in wild-type mice
|
• a major deletion of the midbrain is seen when tamoxifen is given at E9.5, but not when given at E10.5
|
• a major deletion of the medial cerebellum is seen when tamoxifen is given at E9.5 but not when given at E10.5
• when given tamoxifen at E10.5, at P14 the distinction between the vermis and the hemispheres is not apparent
|
• when given tamoxifen at E10.5, at E12.5 the cerebellar primordium is reduced in size
• when tamoxifen treated at E10.5, development of the vermis prepyramidal fissure is delayed and the order of fissure initiation is altered
|
• when given tamoxifen at E10.5, at P14 cerebellar foliation patterns are disrupted
• when given tamoxifen at E13.5 or E14.5, foliation defects in adults are less severe than when tamoxifen is given at E10.5
|
• when tamoxifen treated at E10.5, at E18.5 the thickness of the external granule layer was 1.5-2 times greater in the mutants than in wild types
• when tamoxifen treated at E10.5, at P2 the thickness of the external granule layer is similar in the lobules IV/V and VI unlike in wild-type mice
|
• when tamoxifen treated at E10.5, at P2 thickness is similar to that at E18.5 and thinner than in the controls.
|
• when given tamoxifen at E13.5 or E14.5, in adults the preculminate fissure is absent (between I-II and III) as lobules I-III are fused
• when given tamoxifen at E10.5, at P3 the depth of the primary fissure is increased relative to the intercrural fissure
|
• when given tamoxifen at E10.5, at P14 the anterior region (lobules I-V) is reduced and the central region (lobules VI-VII) is preferentially expanded
|
• when tamoxifen is given at E10.5, at P14, unlike in wild type, the remnants of lobules I-V extend into the hemispheres
• when tamoxifen is given at E10.5, at P14 remnants of the vermis, specific anterior and posterior regions, are maintained more laterally than in wild-type
• when given tamoxifen at E10.5, at P14 in some mutants lobule VIII is diminished more medially than lobule IX rather than the opposite as occurs in wild-type
• when tamoxifen treated at E10.5, at P2 lobules I - V are smaller and lobule VI is much larger than in wild-type
• when tamoxifen is given at E13.5 or E14.5, in adults lobule VIII is shifted posterior and fused with dorsal lobule IX
• when tamoxifen treated at E10.5, at P2 the thickness of the external granule layer is similar in the lobules IV/V and VI unlike in wild-type mice
|
• when given tamoxifen at E10.5, at P14 lobules VI-VII occupy a greater proportion of the vermis than in wild-type
• when given tamoxifen at E10.5, at P14 lobules VIII-IX occupy a smaller proportion of the vermis than in wild-type
• when given tamoxifen at E13.5 or E14.5, in adults lobules I-III are fused into one lobule
|
• when tamoxifen treated at E10.5, at P2 overall size of each region, and thus total number of cells, is greatly reduced
|
• when given tamoxifen, at P3 the cerebellum is smaller compared to controls
