Major developmental defects in Epn1tm1Ocr/Epn1tm1Ocr Epn2tm1Ocr/Epn2tm1Ocr embryos
mortality/aging
|
• die between E9.5 and E11.5
|
embryo
|
• fail to undergo axial rotation in the sagital plane
|
|
• at E9.0 picnotic cells are seen in the neural tube
|
|
• somites that do form are irregular in size and shape
|
|
• somites that do form are irregular in size and shape
|
|
• severely impaired somitogenesis resulting in a reduction in the number of somites formed by E9.5
|
|
• lack large vitelline vessels and the sinusoids are larger and dilated at E9.0 indicating failure to remodel the vascular plexus
|
nervous system
|
• at E9.0, vessels in the telencephalic region fail to form finely branched trees, instead a coarse network of uniformly sized vessels is present
|
|
• at E9.0 picnotic cells are seen in the neural tube
|
cardiovascular system
|
• at E9.0 in the intersomitic region, vessels are only present in areas where somites develop and these vessels are disorganized compared to controls
|
|
• at E9.0, vessels in the telencephalic region fail to form finely branched trees, instead a coarse network of uniformly sized vessels is present
|
|
• defects in angiogenic vascular remodeling
|
|
• atrophic ventricular wall seen at E9.5
|
cellular
N |
• no defects in proliferation or clathrin mediated endocytosis are detected in MEFs in contrast results from previous experiments using Epn1 knockdown cells
