Background It is known that secreted protein acidic and cysteine rich (osteonectin), cwcv and kazal-like domains proteoglycan 2 (SPOCK2) plays a significant role in the development and progression of several human cancers; however, the role of SPOCK2 in prostate cancer (PCa) remains unclear. This study aimed to find the role and mechanism of SPOCK2 in the development and progression of PCa. Methods The messenger ribonucleic acid (mRNA) expression of SPOCK2 in PCa tissue was detected by real-time polymerase chain reaction (PCR). Upregulation of the SPOCK2 gene was achieved using the DU145 and LNCaP cells by transfecting the cells with SPOCK2 recombinant fragment. Cell invasion and migration ability were detected by transwell chamber and wound healing assay. The expression of membrane-type 1 matrix metalloproteinase (MT1-MMP) and matrix metalloproteinase 2 (MMP2) in the cells was detected by Western Blot and zymography gel assay. Results The mRNA level of SPOCK2 was significantly lower in the PCa tissue compared to benign prostate hyperplasia. Upregulation of SPOCK2 inhibited cell invasion and migration in DU145 and LNCaP cells, inhibited the expression of MT1-MMP and MMP2 and, inhibited activation of MMP2 in DU145 and LNCaP cells. Conclusion SPOCK2 is associated with the progression of PCa. Upregulation of SPOCK2 can inhibit PCa cell invasion and metastasis by decreasing MT1-MMP and MMP2 gene expression and decreasing MMP2 protein activation.

Purpose: To investigate the effect of indole-thiazolidinone on metastasis in HK1 nasopharyngeal carcinoma cells. Methods: HK1 cell proliferation was determined colorimetrically using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay. Invasion and migration of HK1 cells were assessed using Matrigel™ chamber coated invasion and wound healing assays, respectively. Results: Indole-thiazolidinone suppressed proliferation of HK1 and NPC 039 NPC cell lines at 72 h. The degree of proliferation of HK1 cells on treatment with 0.25, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 μM indolethiazolidinone was 99, 87, 71, 64, 49, 38 and 31 %, respectively. In HK1 cell cultures, migration potential was reduced to 58.32, 47.54, 28.91 and 17.65 %, on exposure to 1.5, 2.0, 2.5 and 3.0 μM indole-thiazolidinone, respectively. Incubation with 1.5, 2.0, 2.5 and 3.0 μM indole-thiazolidinone resulted in cell invasion values of 63.41, 49.37, 35.12 and 19.67 %, respectively. There was a marked decrease in the expressions of matrix metalloproteinase 2 and matrix metalloproteinase 9 in HK1 cells on treatment with indole-thiazolidinone (p < 0.05). In addition, indole-thiazolidinone treatment resulted in decrease in p65 and p50 in nuclear fraction. Treatment of HK1 and NPC 039 cells with indolethiazolidinone and henenalin synergistically decreased cell proliferation. Indole-thiazolidinone treatment caused significant decrease in tumor growth in mice (p < 0.05). Conclusion: Indole-thiazolidinone inhibits proliferation and metastasis in nasopharyngeal carcinoma cells. Therefore, it has potential for development as a therapeutic management of nasopharyngeal carcinoma in humans.

Purpose: To elucidate the mechanism of CXCR4/EAAT1/GS pathway in CXCL12 regulating invasion and migration in malignant pleural mesothelioma (MPM). Methods: Immunohistochemistry for CXCL12, CXCR4, EAAT1 and GS stainings and correlation analysis between them were conducted in MPM and normal tissues. Western blot and real-time PCR were performed to examine the CXCR4, EAAT1 and GS expression in H2052 cells. Wound healing and transwell assay were applied to determine the cell migration and invasion. MTT was utilized to assess cell viability. Results: CXCL12, CXCR4, EAAT1 and GS were highly expressed in MPM tissues and correlated with each other. CXCL12 upregulated both in protein and mRNA levels of CXCR4, EAAT1 and GS in H2052 cells. The EAAT1 and GS expression upregulated or not by CXCL12 were decreased by CXCR4 and EAAT1 knockdown. CXCR4 antagonist AMD3100 and EAAT1 antagonist TFB-TBOA also resulted in the same effects as CXCR4 and EAAT1 knockdown, respectively. CXCL12 promoted cell invasion and migration and increased the Matrix metalloproteinase 9 (MMP9) mRNA level. CXCR4 and EAAT1 knockdown suppressed all these functions. Furthermore, CXCL12 promoted H2052 cells growth in nude mice, both AMD3100 and TFB-TBOA inhibited this promotion. Conclusions: CXCL12 regulated the invasion and migration through CXCR4/EAAT1/GS pathway in H2052 cells.
