mortality/aging
|
• lethality is seen between 3 and 20 weeks of age
|
|
• only 38% of the expected number of mice are present at weaning
|
|
• only 46% of the expected number of embryos are present at E18.5
|
growth/size/body
skeleton
|
• small extra bone present above C1 in 38% of double homozygous mice
|
|
• transformation of T7 to T8 and T13 to L1 are seen in 62% and 100% of double homozygous mice, respectively
|
|
• transformation of C1 to C2, C5 to C6, and C7 to T1 are seen in 92%, 23%, and 8% of double homozygous mice, respectively
• partial transformation of C7 to T1 is seen in 85% of double homozygous mice
|
|
• transformation of L6 to S1 is seen in 100% of double homozygous mice
|
hematopoietic system
|
• shift in the distribution of myeloid to B lymphoid cells resulting in an increased percentage of myeloid cells

|
|
• decreased number of hematopoietic cells in the thymus, bone marrow and spleen
|
cellular
|
• impaired ability of serum-starved MEFs to re-enter the cell cycle
|
|
• defect in asynchronous proliferation in MEFs
|
behavior/neurological
|
• similar to that seen in mice homozygous for Bmi1tm1Brn alone at 2 months of age
|
nervous system
|
• all three layers are affected
• hypoplasia is similar to that in mice homozygous for Bmi1tm1Brn alone
