Matrix metalloproteinases (MMPs), a family of endopeptidases also known as gelatinases, have been reported to affect the acquisition of the cell proliferative, cell invasive and metastatic phenotype of several types of cancer. In particular, the gelatinases MMP-2 and -9 have been revealed to facilitate tumor growth and invasion in patients with colorectal cancer (CRC). However, it is not known whether the gelatinase activity of MMP-2 and -9 is also elevated in Vietnamese patients with CRC. The activity of MMP-2 and -9 in the tissue samples of 103 patients with CRC was evaluated by gelatin zymography and quantified using ImageJ...

Glioblastoma multiforme (GBM) is the most malignant type of primary brain tumor in adults and can diffusely infiltrate adjacent normal tissue. GBM is therefore rarely cured by surgery or radiation therapy. Matrix metalloproteinases (MMPs) are involved in tissue remodeling and numerous other physiological progresses. The MMPs MMP-2 and MMP-9 are associated with the invasion ability of GBM. PT93 is a novel caffeic acid amide derivative that was first synthesized in 2013. In the present study, the human GBM T98G, U87 and U251 cell lines and the normal mouse neuron HT22 cell line were used to investigate the anticancer and cytotoxic effects of PT93 in vitro...

A form of microcirculation called vasculogenic mimicry (VM), which constitutes a novel approach for tumor blood supply in certain highly aggressive malignant tumors, was recently reported to contribute to tumor metastasis and poor prognosis in melanoma patients. Development of strategies to target tumor VM may be significant to reduce the recurrence and metastasis of melanoma. Norcantharidin (NCTD) has been shown to inhibit tumor growth and VM of human gallbladder carcinomas. Besides, NCTD could induce melanoma cell apoptosis...

In non-small cell lung cancer (NSCLC), estrogen significantly promotes NSCLC cell growth via estrogen receptor beta (ERβ). However, the effects by which ERβ contributes to metastasis in NSCLC have not been previously reported. This study aims at defining whether the stimulation of ERβ promotes NSCLC metastasis in vitro and in vivo. Here, Our results showed that estrogen and ERβ agonist enhanced aggressiveness of two lung cancer cell lines (A549 and H1793) and promoted murine lung metastasis formation. ER-inhibitor Fulvestrant treatment or ERβ-knockdown significantly suppressed the migration, invasion and nodule formation of NSCLC cells...

The chemokine CCL3 is a chemotactic cytokine crucial for inflammatory cell recruitment in homeostatic and pathological conditions. CCL3 might stimulate cancer progression by promoting leukocyte accumulation, angiogenesis and tumour growth. The expression of CCL3 and its receptors CCR1 and CCR5 was demonstrated in oral squamous cell carcinoma (OSCC), but their role was not defined. Here, the functions of CCL3 were assessed using a model of chemically induced tongue carcinogenesis with 4-nitroquinoline-1-oxide (4NQO)...

AIM: Our previous study found expression of GALNT3 gene was reduced in coronary artery disease (CAD) patients, and it contributed to endothelial injury by regulating apoptosis and matrix metalloproteinase (MMP) expression. GALNT3 gene may be a potential target for future therapeutic intervention of CAD. However, none reports linking the GALNT3 gene to susceptibility of CAD. This study investigated the variant associations of GALNT3 gene and CAD. METHODS: Thirteen single nucleotide polymorphism (SNP) in and around the GALNT3 gene were tagged and analyzed in CAD patients (n = 1515) and control individuals (n = 5019), and the SNPs with CAD were tested with multiple logistic regression analysis in an additive genetic model (with one degree of freedom) after adjusting for age and sex...

MicroRNAs (miRNAs) are small non-coding RNAs which participate in the post-transcriptional regulation of gene expression. They play important roles in cellular events such as growth and differentiation. Deregulation of miRNAs is frequently evident in human cancers where their aberrant expression is associated with uncontrolled proliferation, metastasis, impaired cell cycle and DNA damage response. The miRNAs are important in cancer as ∼50% of miRNA genes are located in cancer-associated regions such as fragile sites of genome...

This investigation identifies interleukin 8 (IL-8) as the main inflammatory mediator in head and neck squamous cell carcinoma (HNSCC). The expressions of chemokines of IL-8, IL-1β and IL-6 and the cytokines of tumor necrosis factor-α (TNF-α) were higher in HNSCC patient tissues than in non-cancerous matched tissues (NCMT) whereas the expression of IL-10 was lower. IL-8 is most highly expressed in the tissues of patients with HNSCC. Treatment of HNSCC cells with IL-8 increased the secretion of IL-1β, IL-6 and TNF-α and reduced IL-10 expression; the increase in the expression of IL-1β was particularly considerable...
