hm1

• Allelic Composition: Rhoj^tm1.2Auem/Rhoj^tm1.2Auem
• Genetic Background: B6.Cg-Rhoj^tm1.2Auem

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

neoplasm

abnormal tumor vascularization ( J:208154 )

• decreased vascular densities, increase in vessel disruptions, and reduced vascular spouting in tumors formed by injection of Lewis lung carcinoma cells

• coverage of tumor vessels with alpha-SMA+ mural cells and basement membrane is decreased and vascular permeability is increased

• vascular densities are also reduced in tumors formed by injected B16F10 melanoma cells

decreased metastatic potential ( J:208154 )

• in tumors formed by injection of Lewis lung carcinoma cells

abnormal tumor morphology ( J:208154 )

• tumors formed by injection of Lewis lung carcinoma cells show an increase in hemorrhagic foci and increased hypoxia with extensive apoptosis in the center of the tumor

decreased tumor growth/size ( J:208154 )

• decreased growth of injected Lewis lung carcinoma cells

• tumor growth is also delayed for injected B16F10 melanoma cells

• impact of cisplatin, VEGF-A blockade, or combretastatin-A4-phosphate on Lewis lung carcinoma cell tumor growth/necrosis is enhanced compared to wild-type controls

homeostasis/metabolism

increased physiological sensitivity to xenobiotic ( J:208154 )

• impact of cisplatin on Lewis lung carcinoma cell tumor growth/necrosis is enhanced compared to wild-type controls

• impact of combretastatin-A4-phosphate treatment on inhibition of tumor growth and inhibition of tumor vascularization is enhanced

cardiovascular system

cardiovascular system phenotype ( J:208154 )

N • no differences from wild-type controls in vascular morphology or integrity are found in untreated mice

abnormal tumor vascularization ( J:208154 )

• decreased vascular densities, increase in vessel disruptions, and reduced vascular spouting in tumors formed by injection of Lewis lung carcinoma cells

• vascular densities are also reduced in tumors formed by injected B16F10 melanoma cells

internal hemorrhage ( J:208154 )

• tumors formed by injection of Lewis lung carcinoma cells show an increase in hemorrhagic foci
