Small size of Sec23bGt(AD0407)Wtsi/Sec23bGt(AD0407)Wtsi neonates

mortality/aging
• generally die within 12 h of birth and none survive past 24 h

behavior/neurological
• fail to suckle

growth/size/body
• degeneration of the nasal glands at E18.5
• about 25% lower than littermate controls

endocrine/exocrine glands
• degeneration of the nasal glands at E18.5
• disruption of the structures of the serous and mucous acini of salivary glands (J:186391)
• E-cadherin and beta-catenin are mislocalized in the salivary glands at E15.5 (J:237614)
• serous acini contain grossly dilated ER and only a small percentage of acini contain secretory granules
• mucous acini contain grossly dilated ER and lack secretory granules
• degeneration of the salivary glands at E18.5
• degeneration of gastric glands
• accumulation of proamylase and other exocrine proteins in the ER
• appears more opaque with a disorganized structure compared to controls
• grape-like clusters are absent and there is no discernible islet structure
• a few cells show distended ER at E13.5 and most cells have grossly distended ER at E16.5 (J:186391)
• E-cadherin (CDH1) is mislocalized to the cytoplasm of acinar cells at E11.5 and largely co-localizes with carboxylpeptidase A (CPA) at E15.5, suggesting that it remains inside the endoplasmic reticulum (J:237614)
• beta-catenin (which binds to CDH1) is also mislocalized at E15.5 (J:237614)
• decrease in the size and number of pancreatic acini
• decrease in the size and number of pancreatic acini
• altered distribution pattern of endocrine cells at E13.5 - E18.5
• alpha and beta cells remain scattered throughout the pancreas rather than migrating to form the islets of Langerhans
• no defects are seen in pre-patterning, branching morphogenesis or pancreatic progenitor fate assignment
• decrease in the volume of the dorsal and ventral pancreas

craniofacial
• degeneration of the nasal glands at E18.5

cellular
• apoptosis of secretory tissues in the in pancreas, salivary gland, and gastric glands in the developing embryo
• apoptosis starts after cells start to synthesize large amounts of secretory cargo

homeostasis/metabolism
N
• embryos do not exhibit collagen secretion defects at E11.5
• at 4 to 8 h after birth under nonsuckling conditions

hematopoietic system
N
• no significant differences in red blood cell count, hemoglobin, or hematocrit levels in neonates

digestive/alimentary system
• grape-like clusters are absent and there is no discernible islet structure
• a few cells show distended ER at E13.5 and most cells have grossly distended ER at E16.5 (J:186391)
