Background: The clinical significance of metastasis associated in colon cancer 1 (MACC1), in human gallbladder cancer, is not yet established. This study was performed to assess the expression of MACC1 in benign and malignant gallbladder lesions, and to assess its clinicopathological significance. Materials and Methods: Tissue samples from resected gallbladder cancer (n = 70) and cholelithiasis (n = 70) were evaluated for MACC1 expression by immunohistochemical staining. Their expression was correlated with different clinicopathological parameters. Results: Cytoplasmic MACC1 expression was significantly higher (58.6%) in gallbladder cancer than in chronic cholecystitis (27.1%, P < 0.001). High MACC1 levels were associated with lymph node metastasis (P < 0.05), tumor node metastasis (TNM) stage (P < 0.01), and perineural invasion (P < 0.01), but not with sex, age, history of gallstones or histological grade (P > 0.05). The univariate Kaplan-Meier analysis showed that a positive MACC1 expression was associated with decreased overall survival (P < 0.001). The multivariate Cox regression analysis showed that MACC1 expression and the histopathological subtypes were independent risk factors for disease-free survival. Conclusion: The expression of MACC1 might be closely related to carcinogenesis, clinical biological behaviors, and prognosis of gallbladder adenocarcinoma.

Objective: To explore the expression of metastasis-associated colon cancer 1 (MACC1) proteins in esophageal carcinoma and neighboring tissues. Methods: The expressions of MACC1 were detected in 60 specimens of esophageal carcinoma and neighboring tissues with immunohistochemistry and Western blotting. All the specimens were selected from 2010-2012 of Guangfu Hospital of Jinhua, 38 males and 22 females, aged (50±12) years. And the correlations of the expressions of MACC1 proteins with the clinicopathologic features of esophageal carcinoma were also analyzed. Results: Expression of MACC1 protein was predominantly located in cytoplasm and membrane. The positivity rates of MACC1 protein were 68.3% (41/60) in esophageal carcinoma tissue and there were significant differences from those in neighboring tissue (25.0 (15/60), P < 0.01). Western blotting analysis showed that the expression level of MACC1 protein in esophageal carcinoma was greater than that in corresponding adjacent tissues (0.64±0.05 vs 0.21±0.10, P < 0.05). Moreover, the positivity rates and relative expressions of MACC1 showed significant correlations with TNM stage and pathology grade (all P < 0.05). Conclusion: The abnormal expression of MACC1 may be associated with malignant progression of esophageal carcinoma. Copyright © 2013 by the Chinese Medical Association.

Metastasis associated in colon cancer 1 (MACC1), a key regulator of the hepatocyte growth factor (HGF)/MET signaling pathway, has been implicated in multiple human cancers. However, little is known regarding its expression and biological function in human gallbladder cancer (GBC). In this study, we focused on the clinical significance and biological functions of MACC1 in GBC and found that MACC1 protein overexpression was frequently detected in GBC tissues. Patients with MACC1-positive tumors had worse overall survival than patients with MACC1-negative tumors. Furthermore, treatment of GBC lines with MACC1-targeting small interfering RNA oligonucleotides (MACC1-siRNA) significantly reduced the proliferation of GBC-SD and OCUG-1 cell lines and diminished both anchorage-independent growth on soft agar and cell migration. These data indicate that MACC1 acts as a putative oncogene in GBC and could be a novel diagnostic and therapeutic target for GBC. © 2014 International Society of Oncology and BioMarkers (ISOBM).
