increased sarcoma incidence ( J:234760 )
• mice injected intramuscularly with an adenovirus expressing cre recombinase (Ad-Cre) develop soft-tissue sarcomas in the region 3 to 12 months after cre exposure

• tumors arising from intramuscular Ad-Cre injection show higher proliferation than tumors arising from sciatic nerve Ad-Cre injection
• treatment of tumor cells isolated from intramuscularly Ad-Cre injected mice with the MEK inhibitor PD325901results in decreases colony-forming units and cell proliferation
• treatment of Ad-Cre intramuscularly injected mice with the MEK inhibitor PD325901 delays tumor growth, reduces proliferative index of tumors, and decreases CD31+ microvessel density but does not alter mast cell levels in tumors
