PCBP1 and neoplasm: As shown in Fig. 1b, PCBP1 mRNA was downregulated 12.2 ± 1.55 folds in metastatic tissue compared with normal peritoneum, indicating that loss of PCBP1 expression might be the pervasive mechanism dictating its attenuation of tumor suppressor role in the context of peritoneal metastasis in gastric cancer.
