Figure Lengend Snippet: Figure 1 Model of CIP2A involvement in the EGFR-RAS signaling pathways. ETS1 mediates CIP2A overexpression in human cancers with increased EGFR-MEK-ERK pathway activity. A positive feedback loop of CIP2A and MEK/ERK signaling pathways is shown.

Article Snippet: CIP2A expression was assessed by IHC using monoclonal antibodies to CIP2A (NB100-74663, 1:1200; Novus Biologicals, Littleton, CO, USA).

Figure Lengend Snippet: Figure 2 Immunohistochemical (IHC analysis of CIP2A expression in patients with colorectal cancer. Representative examples of CIP2A expression: (a) strong expression in colorectal liver metastasis, (b) weak expression in colorectal liver metastasis, (c) staining in paired colon cancer, (d) colorectal metastasis tissues, and (e) H-score in paired colon cancer and liver metastasis samples. CIP2A was not consistently overexpressed in colon cancer compared with colorectal liver metastasis in paired tissue specimens.

Figure Lengend Snippet: Figure 3 Kaplan–Meier survival plot of overall survival (OS) by KRAS genotype. (a) OS was significantly worse in patients with wild type KRAS and strong CIP2A expression, compared with patients with wild type KRAS and weak CIP2A expression (P = 0.035). (b) No difference in OS associated with CIP2A expression was observed in mutant KRAS patients (P = 0.759).

Figure Lengend Snippet: Figure 4 Interaction between CIP2A, KRAS genotype and proliferation in the Caco-2 KRAS wild-type cell line. The result of immunoblot and proliferation assay is shown in (a) and (b), respectively. Column 1 vs. 2: CIP2A knockdown by shCIP2A resulted in decreased CIP2A, KRAS, and pERK expression as well as decreased proliferation; Column 1 vs. 3: KRAS overexpression by pCMV6-KRAS G12D resulted in increased KRAS, CIP2A, and pERK expression, as well as increased proliferation; Column 3 vs. 4: in Caco-2 cells with KRAS overexpression by pCMV6-KRAS G12D, knockdown of CIP2A by shCIP2A resulted in decreased CIP2A and KRAS expression. However, it did not cause significantly decreased pERK expression or decreased proliferation (*P < 0.05).
