homeostasis/metabolism
• cold exposed-mice fail to maintain their body temperature unlike wild-type mice
• in mice fed a high fat diet but not standard chow
• at 3 months, especially during the dark cycle
• at 3 months, especially during the dark cycle
• at 16 weeks in male, but not female, mice
• trend at 25 weeks in male, but not female, mice

adipose tissue
• mouse embryonic fibroblasts exhibit a large decrease in adipogenesis compared with wild-type cells
• at P5, interscapular brown adipose tissue exhibits decreased Oil red O staining compared to in wild-type mice
• however, brown adipose tissue mass is normal
• 2-fold as early as 16 weeks
• in male and female mice as early as 16 weeks

growth/size/body
• as early as 16 weeks

immune system
• white adipose tissue macrophage exhibit an activated M1 inflammatory phenotype unlike in wild-type mice

liver/biliary system
• in male mice at 10 weeks

hematopoietic system
• white adipose tissue macrophage exhibit an activated M1 inflammatory phenotype unlike in wild-type mice

nervous system
N
• mutants do not show significantly altered behavior or impaired neurogenesis in the hippocampus
• more proliferating cells are found in the outer half of the granule cell layer (oGCL) than in control tissue where most cells are in the subgranular zone (SGZ) at 1 day after BrdU labeling; oGCL contains 5.9% of total BrdU-labeled cells compared to 1.9% in wild-type
• survival of dentate progenitor cells is reduced in mutants with only ~50% of BrdU-labeled cells surviving 4 weeks compared to wild-type

cellular
• cultured aortic smooth muscle cells do not show enhanced migration in response to PDGF-AA whereas control cells show significant migration
• smooth muscle cells show significantly decreased proliferative responses to PDGF-AA compared to wild-type cells

homeostasis/metabolism
• PDGF-AA activates ERK kinase activation only in wild-type, but not mutant aortic smooth muscle cells
• autophosphorylation of the PDGFalpha receptor is absent in mutant cells stimulated with PDGF-AA
