Matrix metalloproteinase‑1 expression is regulated by HIF‑1‑dependent and epigenetic mechanisms and serves a tumor‑suppressive role in gastric cancer progression. Int J Oncol 2021; 59:102.

Abstract
The matrix metalloproteinase (MMP) family is associated with degradation of the extracellular matrix and is known to promote cancer invasion. The present study aimed to investigate the biological role of MMP-1 in gastric cancer cells and analyze the association between MMP-1 expression and the clinical outcomes of gastric cancer patients. In the present study, hypoxia accelerated invasion, accompanied by elevated MMP-1 expression in the gastric cancer cell line 58As9. Additionally, hypoxia-inducible factor-1α (HIF-1α) knock- down in 58As9 cells reduced MMP-1 expression under hypoxic conditions. Treatment with 5-aza-2-deoxycytidine and trichostatin A restored MMP-1 expression in the MMP-1-deficient cell lines MKN45 and MKN74. These results indicated that MMP-1 expression was controlled by both HIF-1α-dependent and epigenetic mechanisms in gastric cancer cell lines. In addition, MMP-1 knockdown impaired the hypoxia-induced invasiveness of 58As9 cells, implicating MMP-1 in the elevated invasion. By contrast, knockdown enhanced the proliferative ability of 58As9 cells, whereby expression of cell cycle-related genes was subsequently altered. In nude mouse models, the knockdown accelerated the growth of xenograft tumor and the development of peritoneal dissemination. In an immunohistochemical study using 161 surgically resected cancer tissues, the Ki67 score was significantly higher in the group with low MMP-1 expression (P<0.001). Disease-free survival (DFS) and disease-specific survival (DSS) were both significantly reduced in patients with low MMP-1 expression (log-rank test; DFS: P=0.005; DSS: P=0.022). Multivariate analysis demonstrated that MMP-1 expression was an independent prognostic factor for DFS and DSS [DFS: HR=2.11 (1.22–3.92) P=0.005, DSS: HR=2.90 (1.23–8.50) P=0.012]. In conclusion, the present study indicated that MMP-1 may serve as a tumor-suppressive factor that inhibits gastric cancer progression, although it promoted invasion in vitro.

Abstract
BACKGROUND The phenotypic heterogeneity of circulating tumor cells (CTC) in peripheral blood and disseminated tumor cells (DTC) in bone marrow is an important constraint for clinical decision making. Here, we investigated the implications of two different subpopulations of these cells in gastric cancer (GC). METHODS GC patients (n = 228) who underwent elective gastric resections were prospectively examined for CTC/DTC. The cells obtained from peripheral blood and bone marrow aspirates were sorted by flow cytometry and CD45- cells expressing cytokeratins (8, 18, and 19) and CD44 were identified by immunofluorescent double staining. RESULTS Ninety-three (41%) patients had cytokeratin-positive tumor cells in either blood or bone marrow, while cells expressing CD44 were found in 22 (10%) cases. CK+CD44+ cells were significantly more common among patients with distant metastases (50 vs 19%, P = 0.001), while no such correlations were demonstrated for CK+CD44- cells. Detection of CK+CD44+ cells, but not CK+CD44-, was associated with significantly shortened survival. Moreover, the Cox proportional hazards model identified CK+CD44+ cells as a negative prognostic factor with an odds ratio of 2.38 (95% CI 1.28-4.41, P = 0.006). CONCLUSION CD44+ phenotype of cytokeratin-positive cells in blood and bone marrow is an independent prognostic factor in patients with gastric cancer.

Plastin3 is associated with epithelial-mesenchymal transition and poor prognosis in gastric cancer. Oncol Lett 2018; 17:2393-2399.

Abstract
The plastin3 (PLS3) gene, which encodes an actin bundling protein known to inhibit cofilin-mediated depolymerization of actin fiber, has been previously reported to serve an important role in the epithelial-mesenchymal transition (EMT) in cancer. The aim of the present study was to determine the clinical significance of PLS3 and its role in regulating EMT, as well as in promoting cell invasion and migration in gastric cancer. The expression of plastin3 mRNA was measured in 163 resected gastric cancer specimens, in order to determine the clinicopathological significance. Furthermore, in vitro invasion and migration assays were performed on gastric cancer cells, which revealed that PLS3 expression was suppressed. The high PLS3 expression group had a higher incidence of advanced tumour stage, cancer differentiation, tumour invasion depth and distant metastases compared with the low PLS3 expression group (P<0.05). In addition, the high PLS3 expression group had a significantly poorer prognosis than the low expression group (P=0.012). Multivariate analysis indicated that high PLS3 expression was an independent prognostic factor for survival. The present study also identified that suppression of PLS3 in gastric cancer cells was associated with decreased cell invasion and migration. The findings from the present study indicate that high expression of PLS3 in gastric cancer is independently associated with a poor prognosis, and that PL3 serves an important role in EMT.

Abstract
Epidermal growth factor receptor–tyrosine kinase inhibitor (EGFR-TKI) resistance is one of the most important problems in lung cancer therapy. Lung adenocarcinoma with EGFR-TKI resistance was reported to have higher abilities of invasion and migration than cancers sensitive to EGFR-TKI, but the function of matrix metalloproteinases (MMPs) has not been explored in EGFR-TKI–resistant lung adenocarcinoma. This study aims to clarify the significance of MMP-1 in EGFR-TKI–resistant lung adenocarcinoma. From the results of in vitro studies of migration and invasion assays using EGFR-TKI–sensitive and –resistant cell lines and phosphorylation antibody arrays using EGF and rapamycin, we first demonstrate that overexpression of MMP-1, which might follow activation of a mammalian target of rapamycin (mTOR) pathway, plays an important role in the migration and invasion abilities of EGFR-TKI–resistant lung adenocarcinoma. Additionally, immunohistochemical studies using 89 cases of lung adenocarcinoma demonstrate that high expression of MMP-1 is significantly correlated with poor prognosis and factors such as smoking history and the subtype of invasive mucinous adenocarcinoma. These are consistent with the results of this in vitro study. To conclude, this study provides insights into the development of a possible alternative therapy manipulating MMP-1 and the mTOR signaling pathway in EGFR-TKI–resistant lung adenocarcinoma.

Abstract
Epigenetic processes including aberrant promoter methylation of tumor suppressor gene play a key role in gastric carcinogenesis. TET proteins are involved in DNA demethylation; many cancers, haematological or solid, present loss-of-function mutations and aberrant expression/regulation of TET. In gastric cancer there are few studies reporting a decreased expression of TET and associations between these proteins and signaling pathways involved in carcinogenesis. Identifying connections between aberrant expression of TET, disruption of the balance between DNA methylation and demethylation and their association with gastric carcinogenesis might be useful for the development of novel therapeutic approaches.

Abstract
Matrix metalloproteinase-1 (MMP-1), an interstitial collagenase, is responsible for the proteolytic degradation of basement membrane and extracellular matrix. MMP-1 plays a major role in the invasion of gastric cancer (GC). The role of the genetic polymorphisms in the functional regions of MMP-1 on the risk of GC remains unclear. To identify the markers that contribute to the genetic susceptibility to GC, we examined the potential association between GC and nine single-nucleotide polymorphisms (rs 1799750, rs 498186, rs 475007, rs 514921, rs 494379, rs 996999, rs 2071232, rs 1938901, and rs 2239008) of the MMP-1 gene using the MassARRAY system in this study. The participants enrolled in this study included 422 patients with GC and 428 healthy subjects as the healthy controls from a Chinese Han population. The analysis revealed a weak association between the rs 1799750 (in the promoter region) genotype distribution and GC (p=0.020). The frequency of the 2G allele was significantly higher in the patients with GC than in the healthy controls (p=0.005, odds ratio [OR]=1.324, 95% confidence interval [CI]: 1.087-1.613). Moreover, the patients with the 2G/2G genotype of rs 1799750 had a significantly increased risk of cancer invasion compared with patients with the 1G/1G+1G/2G genotype (p=0.001, OR=0.505, 95% CI: 0.331-0.771). Strong linkage disequilibrium was observed in three blocks (D'>0.9). Significantly, more C-2G haplotypes (block 3) (p=0.0005 after Bonferroni correction) were found in GC subjects. These findings point to a role for MMP-1 promoter polymorphism in GC among a Han Chinese population, and may be informative for future genetic or biological studies on GC.

Abstract
Head and neck squamous epithelial cell cancer (HNSCC), the world's fifth most common type of cancers, is associated with short life expectancy and high death rates if not detected in early stages. The aim of this study was to investigate hRRM1 and p53R2 gene polymorphisms by using real-time PCR technique in patients with head and neck cancer. In total, 87 patients with head and neck malignancies and 87 control group who have not any malignancies were included in the study between January 2011 and February 2012 in Istanbul University Faculty of Medicine Department of ORL. In the study, real-time PCR was used to detect hRRM1 (rs12806698 C/A) and p53R2 (rs2290707 G/T) gene polymorphisms in Turkish HNSCC patients and healthy individuals. Genomic DNA isolation was performed according to the kit protocol with spin column. LightCycler 1.5 system was used to perform SNP genotyping using hybridization probes consisting of 3'-fluorescein and a 5'-LightCycler Red labeled pair of oligonucleotide probes. There were significant differences in the distribution of hRRM1 genotypes. Frequency of individuals with hRRM1 AA genotype was higher in patients with less differentiation when compared with well differentiation [p 0.025, Fisher's exact test, odds ratio (OR) 0.140, 95 % confidence intervals (CI) 0.024-0.797]. It is observed that A allele carriers have nearly twofold risk for development of the disease (p = 0.022; χ (2) 5.24; OR 2.02, 95 % CI 1.10-3.72).

Abstract
Background. During progression of gastric cancer (GC), degradation of the extracellular matrix is mediated by the matrix metalloproteases (MMPs) and their tissue inhibitors (TIMPs): changes in the expression of these have been related to unfavorable prognosis in GC. Objective. To analyze the expression of certain MMPs and TIMPs in chronic superficial gastritis (SG) and GC. Methods. The expression of MMPs and TIMPs was determined using qRT-PCR; the expression was classified, using threshold cycle (CT) values, as very high (CT ≤ 25), high (CT = 26–30), moderate (CT = 31–35), low (CT = 36–39), or not detected (CT = 40). Strength of association was estimated between the proteins, which were detected by Western blot, and the risk of developing GC. Results. We found a high expression of MMP1, MMP2, MMP14, TIMP1, and TIMP3; moderate one of MMP9 and MMP25, and low one of MMP13 and MMP24 in both tissues. In absolute mRNA levels, significant differences were found in expression of MMP2, MMP24, and MMP25, which are overexpressed in GC compared with SG. The presence of the proteins MMP-14 and TIMP-3 was associated with the risk of developing GC. Conclusions. We consider that MMP2, MMP24, and MMP25 and the proteins MMP-14 and TIMP-3 could be candidates for prognostic molecular markers in GC.

Abstract
Gastrointestinal (GI) carcinoma is a common malignant disease worldwide. Its development and progression is a multistage process involving a multifactorial etiology. Although the detailed mechanisms of the development of GI carcinoma remain controversial, the elucidation of its molecular biology over the last few years has resulted in a better perspective on its epidemiology, carcinogenesis and pathogenesis. More significantly, it is currently possible to use biological indicators or biomarkers in differential diagnosis, prognostic evaluation and specific clinical interventions. In this review, we aimed to describe the biomarkers of pathogenesis, invasion, metastasis and prognosis of GI carcinoma and discuss their potential clinical applications. The majority of these biomarkers, such as tumor-associated antigens, oncogenes and tumor suppressor genes, metastasis-associated genes, cell adhesion molecules, cytokines, growth factors and microRNAs, are currently broadly applicable.
