Gene expression analysis of tumors revealed no diet-dependent reduction in transcripts associated with total leukocytes (CD45, Ptprc), macrophages (F4/80, Emr1), total T cells (Cd3e), or cytotoxic T cells (Cd8b), indicating that FA restriction effects on tumor growth were not driven by immunodeficiency in FA-deprived C57Bl/6 nude mice (data not shown). Here, PTPRC is linked to neoplasm.
