mortality/aging
• mice exhibit a shortened overall survival, with a median lifespan of 184 days versus 239 days in control littermates that are wild-type for Dlg2
|
neoplasm
• tumor cells are more proliferative than those in control littermates that are wild-type for Dlg2, as indicated by Ki-67 staining
|
• mice show accelerated osteosarcoma development with anatomical distribution and histological features similar to those in control littermates that are wild-type for Dlg2
• osteoblastic tumors are aggressive in nature, as indicated by abundant osteoid deposition at the invasive front of thoracic vertebra osteosarcomas
• plump tumorous osteoblasts and massive osteoid deposition are seen in tumors that develop at different sites
|
• at 22 weeks of age, mice show accelerated tumor onset with visible signs of osteosarcomas on the tibia and ribs, unlike control littermates that are wild-type for Dlg2
