Tumors from TSK mice also had a higher neutrophil-to-lymphocyte ratio (Figure 6f), which was validated by immunohistochemical analysis of tumor sections stained with antibodies specific for T cells (CD3), NK cells (NKR), and neutrophils (LCN2) (Figure S9 and Figure 6g and Table S3). The gene discussed is LCN2; the disease is neoplasm.
