Article Title: MCPIP1 Controls Hybrid EMT and Tumor Stemness via the IL6 / JAK2 / STAT3 Axis in Pancreatic Cancer

doi: 10.1002/cam4.71179

Figure Lengend Snippet: MCPIP1 is involved in the IL6/JAK/STAT3 signaling pathway in pancreatic cancer. (A) MCPIP1 protein interaction graph obtained from the STRING database. (B) After silencing MCPIP1 expression in pancreatic tumor cells, protein expression of IL6, P‐JAK2, P‐STAT3 in the above two cell lines were measured and analyzed by western blotting, and their statistical analysis is shown. (C) After overexpression of MCPIP1 in pancreatic tumor cells, protein expression of IL6, phosphorylation (P)‐JAK2, and P‐STAT3 was measured by immunoblotting; the statistical analysis is shown in graphs. (D) Detection of the levels of IL6, P‐JAK, and P‐STAT3 in the subcutaneous tumors of nude mice by immunoblotting; the statistical analysis is shown in graphs. (E) Immunohistochemical staining was used to examine IL6 and P‐STAT3 expression in subcutaneous tumors of nude mice (magnification ×200; scale bar 50 μm). NC, negative control group, shMCPIP1; short hairpin RNA targeting MCPIP1; vector, empty vector lentivirus, oe‐MCPIP1, overexpression of MCPIP1. The mean ± SD of the three experimental groups. Statistical significance of comparisons is indicated by * p < 0.05, ** p < 0.01, *** p < 0.001 and **** p < 0.0001.
