Clinicopathological Significance of Human Macrophage Metalloelastase Expression in Esophageal Squamous Cell Carcinoma

Abstract: Objective: Human macrophage metalloelastase is referred to as matrix metalloproteinase (MMP-12), its function in tumors is contradictory. The current study was undertaken to investigate the role of MMP-12 in esophageal squamous cell carcinoma (SCC). Patients and Methods: We analyzed the levels of MMP-12 mRNA expression in 67 patients with primary esophageal SCC by Northern blot analysis and the tissues were subjected to in situ hybridization analysis for MMP-12. Immunohistochemical staining was performed to de… Show more

“…In addition to its proapoptotic effect, we also found that DIRAS1 could mediate ESCC cell motility and invasiveness via deregulating MMP2 and MMP9, which are reported to be involved in tumor cell migration, spreading, invasion and metastasis (40)(41)(42)(43)(44). Luciferase reporter assay further confirmed that DIRAS1 could modulate MMP2 and MMP9 expression at the transcriptional level, suggesting that MMP2 and MMP9 are indeed downstream targets of DIRAS1-mediated signaling.…”

“…32 Moreover, this MMP has been found in different cancers, though its role is still controversial. For example, MMP-12 expression has been associated with dedifferentiation and histological aggressiveness in skin cancer, 33 with increased invasiveness in squamous cell carcinomas of the vulva and esophagus, 34,35 and with metastatic disease in nonsmall cell lung cancer patients. 36 On the contrary, overexpression of MMP-12 has been correlated with better prognosis in patients with colorectal and hepatocellular carcinomas, 37,38 and with diminished growth of lung metastases.…”

“…Despite the use of modern surgical techniques in conjunction with multitreatment modalities such as radio-and chemotherapy, the overall 5-year survival rate remains 40 -60% (1)(2)(3)(4). In an effort to better understand this disease and predict its clinical outcome, numerous molecular markers for tumor progression and prognosis, e.g., STMY3 (5), interleukin 6 (6), C1orf10 (7), and EC45 (8), and for lymph node metastasis, e.g., caveolin-1 (9), EphA2 (10), FAK (11), cystain B (12), and MMP-12 (13), have been identified. This limited information, however, is not enough to clarify the carcinogenesis, tumor progression, and invasiveness of esophageal cancer; just as in the allegory about the five blind men and the elephant, the complete picture of the pathophysiology of the disease remains elusive.…”
