Compared with the sham LF-MF normal mice group, amount of some cytokines was increased in sham LF-MF tumor-bearing mice, including CXC chemokine ligand (CXCL)13, CC chemokine ligand (CCL) 1, interleukin (IL)-1β, IFN-γ-inducible protein (IP)-10, CXCL9, triggering receptor expressed on myeloid cells (TREM)-1, CCL12, granulocyte colony-stimulating factor (G-CSF), IL-1rα and IL-16, while only few cytokines were decreased, including CCL11, CCL5 and CXCL12 (Figure 5A, C, E and F). The gene discussed is TREM1; the disease is neoplasm.
