Abstract
The Nm23 gene has been acknowledged to play a crucial role in lung cancer metastasis inhibitory cascades controlled by multiple factors. Low expression or allelic deletion of nm23-H1 is strongly linked to widespread metastasis and poor differentiation of non-small cell lung cancer (NSCLC). In this study, nm23-H1 was down regulated in epithelial-mesenchymal transition (EMT) and stemness enhancement under cobalt chloride (CoCl2)-induced hypoxia in NSCLC cells. Moreover, knocking down of nm23-H1 by shRNA apparently promoted hypoxia induced EMT and stemness, which was entirely suppressed via over expression of nm23-H1. Mechanistically, the Wnt/β-catenin signaling pathway was found to participate in the nm23-H1-mediated process. Besides, XAV939 prohibited cell EMT and stemness which could be impaired by knocking down of nm23-H1, while stable transfection of nm23-H1 attenuated hypoxia phonotype induced by lithium chloride (LiCl). Generally, our experiment provided evidence that nm23-H1 can reverse hypoxia induced EMT and stemness through the inhibition of the Wnt/β-catenin pathway, which may furnish a deeper perspective into the better treatment or prognosis for NSCLC.

Abstract
Background Nm23‐H1 gene has been found to be an inhibitor of tumor metastasis in lung cancer. MicroRNAs (miRNAs) play key roles in tumor metastasis through multiple signaling pathways. This study explored whether the nm23‐H1 gene could inhibit invasion and metastasis of lung cancer cells by regulating miRNA‐660‐5p targets. Methods Quantitative real‐time PCR (qRT‐PCR) and western blots were used to measure the expression of nm23‐H1 and miR‐660‐5p of various human lung cancer cell lines. Cell counting kit‐8 (CCK‐8), wound‐healing and transwell assay were carried out to assess cell proliferation, migration and invasion of each cell line. Xenograft were applied to determine in vivo effects of miR‐660‐5p among nude mice. Luciferase assay and western blot were performed to determine the target gene of miR‐660‐5p. Results We found that high expression of nm23‐H1 correlated with decreased miRNA‐660‐5p expression. Inhibiting miR‐660‐5p suppressed lung cancer cells progression significantly in vitro, whereas overexpression of miR‐660‐5p facilitated tumor growth and bone metastasis in vivo. In addition, as the potential target gene of miR‐660‐5p, SMARCA5 overexpression in vitro suppressed tumor progression and osteolytic metastasis associated RANKL signaling, which is congruent with the effect of nm23‐H1 on the lung cancer cells. Conclusion Nm23‐H1 inhibits tumor progression and bone‐specific metastasis of lung cancer by regulating miR‐660‐5p/SMARCA5/RANKL axis, which indicates the related genes may serve as potential targets for the treatment of human lung cancer. Key points Significant findings of the study High expression of nm23‐H1 correlated with decreased miRNA‐660‐5p expression. Further, downregulation of miR‐660‐5p significantly suppressed the tumor progression and bone‐specific metastasis of lung cancer cells. What this study adds This is the first study to show an inverse association between nm23‐H1 and miR‐660‐5p, and confirm that nm23‐H1 inhibits tumor progression and bone‐specific metastasis of lung cancer by regulating miR‐660‐5p/SMARCA5/RANKL axis.

Abstract
The expression levels of p16 and nm23-H1 genes in soft tissue sarcoma (STS) were evaluated to investigate correlation of the expression levels with the incidence and prognosis of STS. Tumor tissues and para-carcinoma normal tissues were collected from 64 STS patients. The messenger ribonucleic acid (mRNA) expression levels of p16 and nm23-H1 in the tissues were detected via reverse transcription-quantitative polymerase chain reaction (RT-qPCR), and the protein expression levels of p16 and nm23-H1 in tissues were detected using immunohistochemistry. Spearman's correlation analysis was used for the correlation between expression levels of p16 and nm23-H1 in STS tissues and the correlation between p16 and nm23-H1 mRNA and protein expression. Moreover, the correlation of p16 and nm23-H1 expression levels in tumor tissues with pathological parameters and prognosis of STS patients were analyzed combined with clinical data. Results of RT-qPCR showed that mRNA expression levels of p16 and nm23-H1 in tumor tissues of STS patients were significantly lower than those in para-carcinoma normal tissues (P<0.01). Results of immunohistochemistry showed that the positive expression rates of p16 and nm23-H1 in tumor tissues of STS patients (43.75 and 39.06% respectively) were significantly lower than those in para-carcinoma normal tissues (85.93 and 89.06% respectively). The expression of p16 and nm23-H1 mRNA was positively correlated with protein expression levels. There was a positive correlation between the expression levels of p16 and nm23-H1 in tumor tissues of STS patients. The negative expression of p16 in tumor tissues of STS patients correlated with tumor size, tumor metastasis and clinical staging, and the negative expression of nm23-H1 correlated with tumor metastasis and clinical staging. The overall 5-year survival rate of patients was 54.68%, and the prognosis of patients with positive expression levels of p16 and nm23-H1 was better. Univariate survival analyses revealed that p16 and nm23-H1 were influencing factors of the overall survival rate of STS patients. p16 and nm23-H1 expression in STS is low, and their expression levels are closely related to the pathological parameters and prognosis of STS patients, so they can serve as reference indexes for prognosis estimation of STS.

Abstract
PURPOSE The main aim of the study was to preliminarily investigate the possibly related role of nuclear onco-suppressors maspin and nm23-H1, a metastasis suppressor, in laryngeal squamous cell carcinoma (LSCC). MATERIALS AND METHODS Maspin expression pattern and nuclear nm23-H1 expression were ascertained in 62 consecutive LSCCs. RESULTS Recurrence rate was significantly lower in patients with a nuclear maspin pattern of expression; nuclear nm23-H1 expression was significantly lower in patients who experienced disease recurrence. Disease free survival (DFS) was significantly longer in patients with maspin nuclear pattern or with nuclear nm23-H1 expression ≥10%. A significant association was found between nuclear nm23-H1 expression and maspin pattern of expression in LSCC. KNN discriminant analysis considered N status, maspin sub-cellular localization and nuclear nm23-H1 expression. The selected variables' accuracy in terms of relapse was 82%. Positive predictive accuracy was 100%, and negative predictive accuracy 79%. CONCLUSIONS Nuclear nm23-H1 expression and maspin pattern, also in association, show promise as recurrence indicators in LSCC. Further studies are needed to shed more light on the nm23-H1 mechanism of action in LSCC and thus find ways to restore nm23-H1 loss. These preliminary findings suggest that re-activating maspin functions might represent an important goal in the treatment of advanced LSCC.

Abstract
Liver cancer is the most endemic cancer in a large region of the world. This study investigated the anti-metastatic effects of an extract of Monascus purpureus CWT715 (MP) fermented from sorghum liquor biowaste and its mechanisms of action in highly metastatic human hepatocarcinoma SK-Hep-1 cells. Kinmen sorghum liquor waste was used as the primary nutrient source to produce metabolites (including pigments) of MP. In the presence of 10 µg/mL MP-fermented broth (MFB), the anti-invasive activity increased with increasing fermentation time reaching a maximum at six days of fermentation. Interestingly, MFB also produced maximal pigment content at six days. Treatment for 24 h with MFB (10–100 µg/mL) obtained from fermentation for six days significantly inhibited cell migration and invasion, and these effects were concentration-dependent. MFB also significantly enhanced nm23-H1 protein expression in a concentration-dependent manner, which was highly correlated with migration and invasion. These results suggest that MFB has significant anti-migration and anti-invasion activities and that these effects are associated with the induction of nm23-H1 protein expression.

Abstract
BACKGROUND The tetraspanin KAI1/CD82 was identified as a tumor metastasis suppressor that down-regulated in malignant progression of lung cancer. However, the underlying mechanism of anti-metastasis role of KAI1 in lung cancer is hardly known. In this paper, we sought to study the function and regulatory mechanism of KAI1 in high metastasis lung cancer cell line. METHODS KAI1 expression was detected in high/low metastatic large lung cancer cell line L9981/NL9980 by quantitative real-time polymerase chain reaction (qRT-PCR). The tumor suppressor function of KAI1 was determined by wound healing assay after over-expression or knockdown of KAI1 in L9981 or NL9980 cells. Invasion assay was performed to detect the invasion ability of L9981 by transfection of KAI1. The effect of tumor suppressor p53 on KAI1 expression was measured by western blot and luciferase assay. Then the regulation of KAI1 due to over-expression of metastasis suppressor nm23-H1 was monitored by qRT-PCR, western blot and reporter gene assay. The progression of L9981 cells after p53 and nm23-H1 expression was detected by invasion assay. Also, methylation status of KAI1 promoter in NL9980 and L9981 cells were examined by bisulfite sequencing and methylation-specific PCR. RESULTS We found that KAI1 is down-regulated in high metastatic L9981 cells compare with NL9980 cells. The migration and invasion of L9981 cells were remarkably suppressed in vitro by KAI1 transfection. The migration ability of NL9980 was enhanced by inhibition of KAI1. Furthermore, KAI1 expression was induced after over-expression of p53 or nm23-H1, while cell invasion was inhibited in L9981 cells. The results of reporter analysis indicated that KAI1 promoter region between -922 to -846 could response to nm23-H1. In addition, we discovered only slight methylation of KAI1 promoter, which showed that loss expression of KAI1 in L9981 cells may not due to promoter methylation. CONCLUSIONS The results suggested that nm23-H1 was involved in the KAI1-regulated inhibition of metastasis in lung cancer cells. More insights into the relationship between KAI1 and other metastasis suppressors will pave the way for the elucidation of anti-metastasis mechanism in lung cancer.

Abstract
Our previous study demonstrated that quercetin-metabolite-enriched plasma (QP) but not quercetin itself upregulates peroxisome proliferator-activated receptor gamma (PPAR-γ) expression to induce G2/M arrest in A549 cells. In the present study, we incubated A549 cells with QP as well as quercetin-3-glucuronide (Q3G) and quercetin-3'-sulfate (Q3'S), two major metabolites of quercetin, to investigate the effects of quercetin metabolites on cell invasion and migration, the possible mechanisms and the role of PPAR-γ. We also compared the effects of QP with those of quercetin and troglitazone (TGZ), a PPAR-γ ligand. The results showed that QP significantly suppressed cell invasion and migration, as well as matrix metalloproteinases (MMPs)-2 activity and expression in a dose-dependent manner. The effects of 10% QP on those parameters were similar to those of 10μM quercetin and 20μM TGZ. However, QP and TGZ rather than quercetin itself increased the expressions of nm23-H1 and tissue inhibitor of metalloproteinase (TIMP-2). Furthermore, we demonstrated that Q3G and Q3'S also inhibited the protein expression of MMP-2. GW9662, a PPAR-γ antagonist, significantly diminished such an effect of Q3G and Q3'S. Silencing PPAR-γ expression in A549 cells also significantly diminished the suppression effect of Q3G and Q3'S on MMP-2 expression. Taken together, our study demonstrated that QP inhibited cell invasion and migration through nm23-H1/TIMP-2/MMP-2 associated mechanisms. The upregulation of PPAR-γ by quercetin metabolites such as Q3G and Q3'S could play an important role in the effects of QP.

Abstract
For solid tumors of a malignant origin, the expression of the nm23-H1 gene is a positive prognostic factor. However, for chronic myeloid leukemia (CML), the prognostic role of nm23-H1 gene expression is unknown. The present study investigated the impact of nm23-H1 gene expression on the proliferation and migration of the CML K562 cell line to elucidate the association between nm23-H1 gene expression and CML cell survival. An RNAi lipo-recombinant plasmid of the nm23-H1 gene (pGCsi-nm23-H1) was constructed and transfected into the K562 cells. RT-PCR and western blotting were used to detect nm23-H1 mRNA and protein expression, respectively. The anchorage-independent growth ability of the transfected cells was observed in soft agar culture and the ability of the K562 cells to migrate was determined using a Transwell assay. Following the successful construction and transfection of the pGCsi-nm23-H1 plasmid into the K562 cells, nm23-H1 mRNA and protein expression levels were significantly lower compared with the control group. The stably-transfected pGCsi-nm23-H1 K562 cells exhibited a markedly increased ability to form colonies and the number and sizes of the colonies were significantly increased compared with those of the control. In vitro, the cells migrated through a Matrigel-coated membrane during incubation for 20 h. The Transwell assay revealed that the quantitative number of pGCsi-nm23-H1 K562 cells that migrated into the lower compartment of the invasion chamber was markedly increased compared with the control. In conclusion, nm23-H1 gene expression may inhibit K562 cell proliferation and migration. nm23-H1 may be a cancer suppressor gene and play a significant role in inhibiting the survival of CML cells.

Abstract
BACKGROUND Lung cancer is the leading cause of cancer death in both men and women worldwide. Tumor metastasis is an essential aspect of lung cancer progression and patient death. The nm23-H1 gene has been extensively investigated as a metastasis suppressor gene. Our previous studies have revealed: that a significant relationship exists between the low-level expression nm23-H1 in primary non-small cell lung cancer (NSCLC) with increased metastasis and a poor prognosis; that L9981-nm23-H1 cells (a nm23-H1 transfactant cell) exhibited lower cell proliferation rates, more G0/G1 phase growth, and an increase in apoptosis with a dramatic decrease in the tumor cells' ability to invade than L9981 cells did; and that L9981- nm23-H1 cells also demonstrated a significantly reduced lymph node and distant metastatic capacity in vivo than L9981 cells did in nude mice. METHODS In this study, we construct a plasmid containing the nm23-H1 gene, which was driven by the human telomerase reverse transcriptase (hTERT) promoter. We evaluated the anti-invasion and anti-metastatic effects of pGL3-hTP-nm23 on L9981, a human large cell lung cancer cell line with nm23-H1 negative expression, by transwell assay in vitro and bioluminescence in nude mice models. The toxicity of pGL3-hTP-nm23 and its effects on tumor growth were evaluated in nude mice models after gene therapy. The cell cycles, apoptosis, and proliferation of the nm23-H1 transfactant were also detected by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT assay) and flow cytometry (FCM). RESULTS The results showed that the hTERT-promoter dramatically drives nm23-H1 gene expression, and induces inhibition of cell growth and migration in L9981-luc cells and MRC-5 cells in vitro. nm23-H1 also significantly inhibited the tumorigenesis and distant metastasis of L9981-luc cell in vivo. Moreover, no obvious side effect was detected in normal mouse tissues after intratumoral injection of the vector. CONCLUSION The treatment of the nm23-H1 gene driven by hTERT promoter appears to be a promising approach for the gene therapy of nm23-H1 low-expressed tumors.

Abstract
AIM: To investigate the expression of nm23-H1 and its correlation with the clinicopathological characteristics in human colorectal carcinoma, and to explore the role of nm23-H1 expression in the carcinogenesis, development and metastasis of colorectal carcinoma.
RESULTS: The level of nm23-H1 expression was significantly lower in colorectal cancer tissues than that in cancer-adjacent, normal mucosal or adenoma tissues (58.7% vs 90.5%, 96.0%, 93.8%, P < 0.05), as well as in colorectal cancer patients with lymph node metastasis than that in patients without metastasis (45.5% vs 73.3%, P < 0.05). The expression of nm23-H1 was positively correlated with the differentiation degree (r = 0.192, P < 0.05), but negatively correlated with the depth of invasion (r = -0.263, P < 0.05). Nm23-H1 expression had no relationship with the sex and age of patients', the morphologic type, histological type and sizes of the tumors.
CONCLUSION: Down-regulation of nm23-H1 expression is an important molecular biological event in the carcinogenesis and progression of colorectal carcinoma, and can be used as an index for the judgment of tumor cell differentiation, invasion and lymph node metastasis.

Abstract
AIM: To investigate the influence of allicin on the ultramicromorphology of hepatocellular carcinoma cells, and to explore the genetic mechanism by which allicin inhibits the invasion and metastasis of hepatocellular carcinoma.
METHODS: Human hepatocellular carcinoma BEL-7402 cells were cultured in the presence of adriamycin (5 mg/L), or allicin at low, medium and high concentrations(25, 50, and 100 mg/L, respectively). Metastasis-related ultramicroscopic structures were examined 0.5 hour after drug treatment. Tumor invasion and metastasis inhibitory genes nm23-H1 and P21ras were assayed by flow cytometry 8 hours following treatment. The data were analyzed by χ2 test with SAS 8.2 software.
RESULTS: The growth of BEL-7402 cells was inhibited and apoptosis was induced following allicin treatment. Most of these adherent cells shrinked, with the junctions reduced, the intercellular space widened, and the cell surface microvilli decreased. Although cells treated with adriamycin also showed typical apoptosis morphology, there was no remarkable reduction of the microvilli on cell surface, and the cross junctions of microvilli among cells exhibited no changes either. The fluorescent intensities of the expression of nm23-H1 were l9.19 in negative control group, 119.76 in 5 mg/L adriamycin group, 84.8 in 25 mg/L allicin group, 92.64 50 mg/L allicin group, and 138.08 in 100 mg/L allicin group, respectively. Dose-effect relationship was clearly showed for allicin in the induction of nm23-H1 expression. The fluorescent intensity of 100 mg/L allicin group was remarkably stronger than that of 5 mg/L adriamycin group (138.08 vs 119.76, P<0.05). Negative or low expression of P21ras was observed in all groups, with no difference among them.
CONCLUSION: Allicin can inhibit the invasion of hepatocellular carcinoma cells, which may be caused by its influence on the motor system of hepatocellular carcinoma cells and its upregulation nm23-H1 gene expression.

Abstract
AIM: To explore the relation between heparanase (HPA) and nm23-H1 in hepatocellular carcinoma (HCC), and whether they could be used as valuable markers in predicting post-operative metastasis and recurrence of HCC.
METHODS: Reverse transcription-polymerase chain reaction and immunohistochemistry (S-P method) were used to measure the expressions of HPA mRNA and nm23-H1 protein in primary tumor tissue and paracancerous tissue of 33 cases of HCC. Paracancerous tissues of 9 cases of benign liver tumor were used as normal controls. The results were analyzed in combination with the results of clinicopathological examination and follow-up.
RESULTS: The positive expression of HPA gene was significantly higher in primary tumor tissues of HCC (48.5%, 16/33) as compared to the paracancerous tissues of HCC and normal controls (3.03%, 1/33) (P<0.01). HPA expression was not related with the size of tumor, envelope formation, AFP level, HBsAg state and cirrhosis of liver. The positive rates of HPA mRNA in the group with high tendency to metastasis or recurrence and in the group with metastasis or recurrence during the follow-up were significantly higher than those in the group with low tendency to metastasis or recurrence (62.5% vs 37.5%, P<0.05) and in the group without metastasis or recurrence (78.6% vs 21.4%, P<0.01). The poorly differentiated tumor and tumor of TNM stages III-IV had a higher positive rate of HPA gene expression than the well differentiated tumor and tumor of TNM stages I-II (66.7% vs 33.3%, P<0.05). The positive expression rate of nm23-H1 protein in HCC tissue was significantly lower than that in corresponding non-cancerous or normal liver tissue (45.5, 72.7, 88.9%, P<0.05). nm23-H1 expression was not related with the size of tumor, envelope formation, AFP level, HBsAg state, cirrhosis of liver, Edmondson grade, and TNM stage (P>0.05). The positive rates of nm23-H1 in the group with high tendency to metastasis and recurrence and in patients with metastasis or recurrence during the follow-up were obviously higher than those in the group with low tendency to metastasis and recurrence (P = 0.018) and in the patients without metastasis and recurrence (P = 0.024); but no significant difference was found between HPA positive and negative groups (P = 0.082). According to the results of follow-up, the rate of accuracy in predicting metastasis of positive HPA, negative nm23-H1 and combination of positive HPA with negative nm23-H1 was 78.6% (11/14), 68.8% (11/16) and 88.9% (8/9), respectively.
CONCLUSION: Expression of HPA and/or nm23-H1 is related with metastasis and recurrence of HCC. Detection of the expression rate of HPA and nm23-H1 may help increase the accuracy in predicting post-operative metastasis and recurrence of HCC.
