Abstract

Pyroptosis and macrophage pro-inflammatory activation play an important role in hepatocellular carcinoma (HCC) progression. However, the specific regulatory mechanisms remain unclear. We identified pyroptosis-related differentially expressed genes (DEGs) based on the GSE4183 and GSE44861 datasets as well as EVenn database. Expression levels of key genes were detected by qRT-PCR. IKZF1 was overexpressed in colon cancer cells and tumor-bearing mice, and its functions were assessed by various cell biology assays in vitro and in vivo. To investigate the interactions between IKZF1 and macrophages, a co-culture system was constructed. The activator RO8191 or inhibitor ruxolitinib of the JAK/STAT pathway was employed to confirm whether IKZF1 inhibited colon cancer development by regulating JAK2/STAT5 pathway. Pyroptosis-related hub genes RBBP7, HSP90AB1, and RBBP4 were highly expressed, while IKZF1, NLRP1, and PYCARD were lowly expressed. These hub genes had good performance in distinguishing colon cancer from controls. Furthermore, overexpression of IKZF1 inhibited tumor growth and promoted pyroptosis. Overexpression of IKZF1 suppressed cell proliferation, metastasis, and inactivated JAK2/STAT5 signaling pathway in colon cancer cells. Furthermore, upregulation of IKZF1 promoted M1 macrophage polarization while inhibiting M2 macrophage polarization in vivo and in vitro by inhibiting the JAK2/STAT5 signaling pathway. This study identifies IKZF1 as a potential biomarker inactivating JAK2/STAT5 pathway for colon cancer.

期刊介绍： BBA Molecular Basis of Disease addresses the biochemistry and molecular genetics of disease processes and models of human disease. This journal covers aspects of aging, cancer, metabolic-, neurological-, and immunological-based disease. Manuscripts focused on using animal models to elucidate biochemical and mechanistic insight in each of these conditions, are particularly encouraged. Manuscripts should emphasize the underlying mechanisms of disease pathways and provide novel contributions to the understanding and/or treatment of these disorders. Highly descriptive and method development submissions may be declined without full review. The submission of uninvited reviews to BBA - Molecular Basis of Disease is strongly discouraged, and any such uninvited review should be accompanied by a coverletter outlining the compelling reasons why the review should be considered.
