The results showed that the expression of BCL-2 in tumor cells was negatively correlated with the presence of T cells, Th1 cells and macrophages (Figures 4C,D), and positively correlated with T helper cells and NK cells (Figure 4E), which indicated the promotion of anti-tumor immune responses with the combination treatment of LFU and PTX. This evidence concerns the gene BCL2 and neoplasm.
