• at 4 months of age, total mammary tumor volume is significantly lower than that in mice carrying the transgene on a wild-type background which exhibit tumor sizes of 2000-2500 mm3
• decreased mammary tumor growth is associated with amino acid deficiency and a marked decrease in cell proliferation, mTOR phosphorylation, and HIF1alpha signaling
• no mice develop mammary tumors at 3 months of age, whereas all mice carrying the transgene on a wild-type background start developing tumors in multiple mammary glands at ~72 days
• small tumor nodules are, however, detectable at 4 months of age, indicating a significant delay in mammary tumor development

homeostasis/metabolism
• mammary tumors exhibit amino acid starvation, as evidenced by the increased mRNA levels for asparagine synthetase (ASNS) and CHOP (CCAAT/enhancer-binding protein homologous protein), two genes that are responsive to changes in the amino acid nutritional status of cells
• however, tumor tissues show no compensatory changes in mRNA expression of other amino acid transporters

• in F1 FVB/N mice crossed to the P/J, DBA/1J, NZW/LacJ, C57BL/6NIcr, CAST/Ei, NOD/LtJ, CBA/CaJ, SWR/J, AKR/J, BUB/BnJ, ST/J, KK/HiJ, or MOLF/Ei strains, an increased latency of the onset of the appearance of primary mammary tumors is seen compared to the inbred FVB/N strain
• in F1 FVB/N mice crossed to either the I/LnJ or C58/J strains, an acceleration of the onset of the appearance of primary mammary tumors is seen compared to the inbred FVB/N strain
• in F1 FVB/N mice crossed to the RF/J, C58/J, C57BR/cdJ, NZB/B1NJ, I/LnJ, DBA/2J, KK/HiJ, MOLF/Ei, SEA/GnJ, NZW/LacJ, or CE/J strains, an decrease in pulmonary metastatic index is seen
• in F1 FVB/N mice crossed to the AKR/J strain, an increase in pulmonary metastatic index is seen
