OBJECTIVE: This study aimed to investigate the levels of matrix metalloproteinas-es (MMP)-2, MMP-9 and Twist in tumor tissue and serum from 46 cases of breast cancer patients and 31 cases of benign breast diseases patients by immunohistochemical staining and enzyme-linked immunosorbent assay, respectively. The association of gelatinase and Twist expression with clinicopathological factors was also analyzed in the present study. PATIENTS AND METHODS: The studied population consisted of 46 breast cancer patients and 31 benign breast disease patients. Serum concentrations of MMP-2, MMP-9 and Twist were measured by using human enzyme-linked im-munosorbent assay. The protein expression of Twist, MMP-2 and MMP-9 were determined by im-munohistochemical. RESULTS: The results show that the levels of MMP-2, MMP-9 and Twist expression were significantly increased in tissue and serum from breast cancer group, compared to the group of benign breast lesions diseases (p < 0.05). The pre-operative serum levels of MMP-2, MMP-9 and Twist were positively correlated with their expression in breast cancer tissues, respectively (p < 0.05). We, then, correlated serum and tissue levels of MMP-2, MMP-9 and Twist in breast cancer samples with patients' clinico-pathologic characteristics. Compared to low expression, high serum and tissue levels of MMP-2 and Twist were associated with lymph node metastasis and higher TNM stage, high tissue MMP-9 levels were associated with lymph node metastasis and higher TNM stage, and high serum MMP-9 levels were associated with c-erbB-2 expression. CONCLUSIONS: These data suggest that serum levels of MMP-2, MMP-9 and Twist could be as potential biomarkers for diagnosis and predicting metastasis of breast cancer.

Objective: The purpose of this study was to investigate the expression of Twist in salivary adenoid cystic carcinoma (SACC) and the relations between Twist expression and the clinicopathological characteristics. Methods: The expression of Twist was examined immunohistochemically in 48 cases of SACC, 18 of pleomorphic adenoma and 10 of normal parotid gland. The relationship between Twist expression in SACC and the clinicopathological factors was analyzed. Results: Twist expression was significantly higher in SACC tissues compared with pleomorphic adenomas and normal parotid gland tissues (P < 0.05). Twist expression levels in SACC were significantly associated with histological type, perineural invasion, postoperativerecurrence, and distant metastasis (P < 0.05), rather than age, gender, tumor site, tumor size, or clinical staging (P > 0.05). Conclusion: Twist expression may be associated with tumor cell differentiation, perineural invasion and metastasis of SACC. Twist expression is a potential prognostic factor for disease survival of SACC. © Springer-Verlag Berlin Heidelberg 2010.

The pineal hormone, melatonin (MLT), has been shown to have therapeutic effects in patients with gastric cancer; however, the mechanisms for the anti-cancer effects are unknown. We investigated the effects of melatonin on cell proliferation, apoptosis, colony formation and cell migration in the gastric adenocarcinoma cell line, SGC7901, using MTT assay, Hoechst 33258 staining, flow cytometry, western blot, caspase-3 activity assay, soft agar colony formation assay, and scratch-wound assay. Our results showed that melatonin could inhibit cell proliferation, colony formation and migration efficiency, and it promoted apoptosis of SGC7901 cells. Our findings suggest that the anti-cancer effects of melatonin may be due to both inhibition of tumor cell proliferation and reduction of the metastatic potential of tumor cells. © 2013 The Biological Stain Commission.

Diabetic nephropathy (DN) is a major cause of morbidity and mortality in diabetic patients. Effective therapies to prevent the development of this disease and to improve advanced kidney injury are required. Berberine (BBR) has preventive effects on diabetes and its complications. This study is to investigate the effects of BBR on the expression of E-prostanoid receptors (EPs) in rats with high-fat diet and streptozotocin (STZ)-induced DN and underlying molecular mechanisms of BBR on DN rats. DN model was induced in male Sprague - Dawley rats with high-fat diet and low dose of STZ injection. BBR (50, 100, 200 mg/kg/d) were orally administered to rats after STZ injection and conducted for 8 weeks. The levels of interleukin-6 (IL-6) and prostaglandin E2 (PGE2) in renal cortex were measured by enzyme-linked immunosorbent assay. Expression of EPs receptors (EP1 - EP4) were determined by western blotting. Remarkable renal damage, hyperglycemia and hyperlipidemia were observed in DN rats. BBR could restore renal functional parameters, suppress alterations in histological and ultrastructural changes in the kidney tissues, improve glucose and lipid metabolism disorders, and increase cAMP levels compared with those of DN model group (Wang et al. in Mol Biol Rep 40:2405-2418, 2013). The level of IL-6 and PGE2 were significantly increased in DN model group compared with normal group, BBR could apparently reduced the level of IL-6 and PGE2. Furthermore, the expression of EP1 and EP3 were both increased and EP4 was lessened in the DN model group compared with normal group, BBR could down-regulate total protein expression of EP1 and EP3 of renal cortex in DN rats and up-regulate the expression of EP4, and there is no significant difference on the expression of EP2 among all groups. These studies demonstrate, for the first time, that BBR exerts renoprotection in high-fat diet and STZ-induced DN rats by modulating the proteins expression of EPs in EP - G protein - cAMP signaling pathway. © Springer Science+Business Media 2014.

This article provides an overview of metastases to jaws (MJ), mainly concerning the differences between American and Chinese patients, and exploring the relationship between the primary tumors' prevalence (PTP) and constituent ratio of MJ. Information concerning of 399 MJ cases in 215 papers, including one new case in our hospital, was subjected to statistic analysis. The main clinical features of MJ, such as constituent ratio of PTP and that of MJ, metastatic sites, treatments, and prognosis were summarized. Breast, lung, kidney, prostate and thyroid (in descending order) were the leading primary sites of MJ. Furthermore, the constituent ratio of MJ was found to be correlated with that of PTP in all subjects including American and Chinese subjects in our study. As to metastatic sites in the mandible, a specific "M" shaped pattern appeared regardless of the tumor type or constituent ratios of MJ were in all subjects. Almost all subjects received traditionally palliative treatments, and the prognosis was quite poor. The PTP had a significant impact on the constituent ratio of MJ. However, it was the properties of the microenvironment rather than characteristics or constituent ratios of tumor cells, that decided the metastatic sites in various tumor subjects.
