Project description:To study the mRNA modulating network and different expressed mRNA lists in MHCC-97H-SH-UCK2 cells, we use high-throughout method to genomically detect the expression profile of mRNA
Project description:Tumor-associated macrophages (TAMs) are crucial components of the tumor microenvironment (TME). They play vital roles in hepatocellular carcinoma (HCC) progression. However, the interactions between TAMs and HCC cells have not been fully characterized. In this study, TAMs were induced using human monocytic cell line THP-1 cells in vitro to investigate their functions in HCC progression. S100 calcium binding protein A9 (S100A9), an inflammatory microenvironment-related secreted protein, was identified to be significantly upregulated in TAMs. S100A9 expression in tumor tissues was associated with poor survival of HCC patients. It could enhance the stem cell-like properties of HepG2 and MHCC-97H cells by activating nuclear factor-kappa B (NF-κB) signaling pathway through advanced glycosylation end-product specific receptor (AGER) in a Ca2+-dependent manner. Furthermore, we found that, after treatment with S100A9, HepG2 and MHCC-97H cells recruited more macrophages via chemokine (C-C Motif) ligand 2 (CCL2), which suggests a positive feedback between TAMs and HCC cells. Taken together, our findings reveal that TAMs could upregulate secreted protein S100A9 and enhance the stem cell-like properties of HCC cells, and provide a potential therapeutic target for combating HCC.
