reproductive system
|
• mice exhibit increased corpus cavernosal smooth muscle relaxation in response to nerve stimulation
• however, treatment with an Adora2b antagonist or PEG-ADA reduces priapic activity
|
|
• mice exhibit priapism that is associated with elevated levels of adenosine
• however, treatment with an Adora2b antagonist or PEG-ADA reduces priapic activity
|
mortality/aging
|
• fewer than expected mice are present at E12.5
• no viable mice are present at E11.5
• mice die between E10.5 and E12.5
|
hematopoietic system
|
• extreme at E12.5, indicated by pallor and small fetal liver
|
|
• a small population of Ter119+ CD71low fetal liver cells unlike in wild-type mice
|
|
• primitive erythroblasts at E11.5
|
|
• increased nuclear to cytoplasmic ratio, less condensed and granular nucleus and smaller, less basophilic staining cytoplasm
|
|
• severely impaired at E12.5
• mice exhibit a block in differentiation at the proerythroblast/basophilic erythroblast stage in fetal liver erythropoiesis compared with wild-type mice
|
liver/biliary system
embryo
|
• severely impaired at E12.5

integument
hematopoietic system
|
• a small population of Ter119+ CD71low fetal liver cells unlike in wild-type mice

|
• greater impairment of Ter119+ CD71hi cells than in double homozygotes
|
hematopoietic system
N |
• mice exhibit normal erythroid development
|
mortality/aging
