    ABSTRACT: IntroductionWe investigated Nestin expression in triple-negative breast cancer and examined how the modulation of Nestin expression affects cell cycle progression, survival, invasion and regulatory signaling in breast cancer stem cells (CSC) in vitro.Methods Nestin expression in 150 triple-negative breast cancer specimens were examined by immunohistochemistry. The role of Nestin expression in tumorigenesis was examined by assaying naturally occurring Nestinhigh/Nestinlow CSC from 12 breast cancer tissues, as well as CSC from 26 clinical specimens, where Nestin overexpression and silencing was achieved by genetic manipulation, for their ability to form mammospheres and induce solid tumors. Cell cycle progression, spontaneous apoptosis and invasiveness of Nestin-silenced breast CSC were investigated by flow cytometry and transwell assays. The relative levels of expression of epithelial-mesenchymal transition (EMT) and Wnt/ß-catenin pathway-related molecules were determined by western blotting.ResultsNestin expression was significantly associated with poor survival in patients with triple-negative breast cancer (p¿=¿0.01). Nestinhigh breast CSC rapidly formed typical mammospheres in vitro. Nestinhigh, but not Nestinlow CSC, efficiently formed solid tumors in vivo. Nestin silencing induced cell cycle arrest at G2/M (52.03% versus 19.99% in controls) and promoted apoptosis (36.45% versus 8.29% in controls). Nestin silencing also inhibited breast CSC invasiveness, and was associated with significantly upregulated E-cadherin, while N-cadherin, vimentin, a-smooth muscle actin (a-SMA), matrix metalloproteinase-2 (MMP-2), MMP-9 and vascular endothelial growth factor (VEGF) expression was downregulated (p¿<¿0.05 for all). Nestin silencing also upregulated Axin, glycogen synthase kinase-3 beta (GSK-3ß), adenomatous polyposis coli (APC), and peroxisome proliferator-activated receptor alpha (PPARa), and downregulated ß-catenin, c-Myc, cyclin D and MMP-7 expression in CSC. Inhibition of the Wnt/ß-catenin pathway mitigated mammosphere formation in Nestinhigh CSC, while inhibition of GSK-3ß promoted the mammosphere formation in Nestinlow CSC (p¿<¿0.05 for all).Conclusions Our data indicates that Nestin positively regulates the proliferation, survival and invasiveness of breast CSC by enhancing Wnt/ß-catenin activation.

    ABSTRACT: It is well-established that triple-negative breast cancer (TNBC) is a subtype of breast cancer, characterized by a poor prognosis and aggressive biological behavior. However, the available relevant data on TNBC in non-Western populations are limited. In order to analyze the clinicopathological and molecular biological characteristics and observe survival and prognostic factors, 972 breast cancer patients (156 of whom had TNBC) who received treatment at the First Affiliated Hospital of Medical School of Xi'an Jiaotong University and the First Hospital of China Medical University, between January, 2004 and January, 2007 were retrospectively evaluated. In the univariate analysis, tumor size, TNM stage, axillary lymph node status and recurrence or metastasis were identified as prognostic factors for 7-year disease-free survival (DFS) and overall survival (OS). Our multivariate Cox's regression analysis demonstrated that tumor size and axillary lymph node status were significant prognostic factors for 7-year DFS and OS. Notably, tumor subgroup (TNBC vs. non-TNBC) was a significant prognostic factor associated with 7-year DFS and OS in breast cancer. It was suggested that TNBC exhibited a worse 7-year survival compared with that in non-TNBC patients, most likely due to its more aggressive behavior and insensitivity to specific therapy.

    ABSTRACT: Interleukin 27 (IL-27), belonging to the IL-12 family, exerts a critical role in immune regulation of infection, autoimmunity, and tumor. In this study, we aimed to investigate the roles of IL-27 and vascular endothelial growth factor (VEGF) in breast cancer. The serum levels of IL-27 and VEGF in 150 patients with breast cancer and 90 control subjects were measured by an enzyme-linked immunosorbent assay. Estrogen receptor, progesterone receptor, and human epithelial growth factor receptor 2 were measured by immunohistochemistry. Clinical stage, tumor size, lymph node metastasis, grade, and histological type were also recorded. The serum levels of IL-27 and VEGF were significantly greater in breast cancer patients than in the control group. In addition, there was a significant correlation between IL-27 and VEGF, and serum IL-27 and VEGF levels were associated with the clinical stage of breast cancer. Moreover, the serum levels of IL-27 were especially elevated in breast cancer patients who were estrogen receptor-positive and progesterone receptor-positive. Furthermore, the serum levels of IL-27 and VEGF decreased after patients with breast cancer had modified radical mastectomy. Interleukin 27 may be a new prognostic biomarker of breast cancer and a promising target to limit both angiogenesis and tumor growth.

    ABSTRACT: The purpose of this study is to investigate the relationship between nestin expression and clinicopathological characteristics, immunohistochemical markers and to determine the prognostic impact of nestin expression in breast cancer so as to lay a foundation for the treatment of breast cancer. A total of 109 patients who were histologically diagnosed with breast cancer and underwent radical operations from January 2006 to September 2007 in China Medical University were enrolled in the study. Nestin protein expression was evaluated by immunohistochemistry. The relationship between nestin and other parameters was analyzed by using chi-square test and Fisher's exact test. Nestin expression was observed in 37.6 % (41/109) of cases. There were no significant differences between the age of >40 and ≤40 years group in terms of nestin expression (39.8 vs 18.2 %; P = 0.161). The rate of nestin expression between those with and without lymph node metastasis was not significantly different (X (2) = 0.086; P = 0.769). The 5-year survival rates of the patients with nestin expression and those without were 34.1 % (14/41) and 55.9 % (38/68), respectively (P = 0.028). Overall, triple-negative breast cancers had higher expression rates than other cancers (54.1 vs 29.2 %; P = 0.011). Nestin expression rate in ER- and PR-negative tumors was found to be significantly higher than cases that were ER- and PR-positive (P = 0.011 and P = 0.036, respectively). However, it was not found that HER2 expression was related to nestin expression (P = 0.120). These results suggest that the expression of nestin might play an important role in the prognosis of breast carcinoma, especially in the triple-negative subgroups.

    ABSTRACT: The aim of this study is to explore the expression of BAF250a protein in breast cancer and its association with the clinical and pathological characteristics and prognosis of breast cancer. The expression status of BAF250a protein was detected by Western blot analysis and immunohistochemical staining. The relationship between BAF250a proteins and clinicopathological parameters in 496 breast cancer specimens was analyzed. Western blot analysis showed that BAF250a protein had a lower expression in breast cancer specimens than in matched normal breast tissue (104.38 ± 11.65 vs. 55.94 ± 10.27; P = 0.004, t test). Among the 496 enrolled breast cancer patients, BAF250a protein expression was absent in 324 (65.3 %). Universal and multiple analyses indicated that BAF250a protein expression loss was significantly related to histological grade, metastatic nodes, tumor node metastasis (TNM) stage, and the expression of estrogen receptor (ER), progesterone receptor (PR), c-erbB-2, and p53 (all P < 0.05). For TNM stage, rank correlation coefficients were 0.199 and 0.191, respectively, (P < 0.05), but BAF250a protein deletion had either a positive or a negative correlation with ER, PR, c-erbB-2, and p53 protein expression (correlation coefficients were 0.231, 0.207, -0.098, -0.128; P < 0.05). Analysis of survival rates showed that the patients with BAF250a protein expression attained a significantly better postoperative disease-specific survival than those with BAF250a protein deletion (88.4 vs. 79.0 %; P = 0.003). In the Cox regression test, BAF250a protein deletion was detected as an independent prognostic factor (P = 0.014). BAF250a protein might be a new potential target for breast cancer treatment.

    ABSTRACT: The objective of this study was to investigate the expression and significance of the GRHL3 protein in breast cancer diagnosis and prognosis. Overall, 111 patients with histologically confirmed breast cancer who had undergone radical surgery were enrolled in this study. The GRHL3 protein expression status in the breast cancers was evaluated by immunohistochemistry. The relationship between GRHL3 protein expression status and clinicopathological factors and the breast cancer prognoses was also determined. In total, 71 (63.96 %) out of 111 cases were found to express GRHL3 protein. GRHL3 expression was higher in breast cancers, compared to other pathologic cancer types (χ (2) = 5.68, P < 0.05). Moreover, GRHL3 protein was also observed to correlate with breast cancer clinical stage and histological grade (χ (2) = 7.99, P < 0.05 and χ (2) = 7.907, P < 0.05, respectively). Interestingly, triple-negative breast cancers had lower expression rates than other breast cancers (41.18 vs. 71.28 %, P < 0.05). GRHL3 was shown to be an independent prognostic factor of breast cancer in Cox regression analysis. Altogether, our results indicate predominant GRHL3 expression in breast cancers, especially non-triple-negative cancers and early stage cancers. GRHL3 expression appeared to decrease with tumor progression. Survival analysis demonstrated the inhibitory effect of GRHL3 in breast cancer. These results strongly suggest the possible involvement of GRHL3 in tumor suppression.

    ABSTRACT: To investigate the expression status of PIWIL2 and piR-932 in breast cancer stem cells and the role they could play in tumor cell growth and metastasis through Latexin. CD44(+)/CD24(-) tumor cells (CSC) from clinical specimens were sorted using flow cytometry. PIWIL2 expression status was detected in CSC cells by microarray analysis and 1086 breast cancer specimens by Western blot and immunohistochemistry staining. piR-932 expression was also detected in CSC cells by piRNA microarray assay. The relationship between the PIWIL2 protein and clinico-pathological parameters and prognosis was subsequently determined. CSC cells are more likely to generate new tumors in mice and cell microspheres that are deficient in NOD/SCID compared to the control group. PIWIL2 protein was expressed higher in CSC cells compared to the control cells. In total, 334 (30.76%) of the 1086 breast cases showed high PIWIL2 expression. PIWIL2 was observed to be related to age, tumor size, histological type, tumor stage, and lymph node metastasis (all P < 0.05). Furthermore, we have found that one of the Piwi-interacting RNAs (piRNAs) called piR-932 expressed significantly higher in the breast cancer cells that were induced to EMT, and it could form immune complexes through immunoprecipitation with PIWIL2; in PIWIL2+ breast cancer stem cells, Latexin expression significantly reduced because of its promoter region CpG island methylation. These results suggest that the combination of piR-932 and PIWIL2 may be a positive regulator in the process of breast cancer stem cells through promoting the methylation of Latexin, and they both could be the potential targets for blocking the metastasis of breast cancer.

    ABSTRACT: The aim of this study was to investigate the correlation between Girdin and PI3K in breast cancer stem cells and the clinical implications of the co-expression of these two proteins in breast cancer patients. CD44(+)/CD24(-) tumor cells from the MD-231 cell line were sorted by flow cytometry. The expression status of Girdin and PI3K proteins was detected using western blotting and immunohistochemical staining. The relationship between Girdin and PI3K proteins and clinicopathological parameters was analyzed in 820 breast cancer patients. Girdin and PI3K proteins were more highly expressed in CD44(+)/CD24(-) tumor stem cells compared to the control group and Girdin and PI3K proteins were co-immunoprecipitated in the MD-231 cell line. Of the 820 enrolled breast cancer patients, Girdin and PI3K proteins were expressed in 295 (35.98%) and 492 (60.00%) cases, respectively. There were 162 (19.76%) cases which co-expressed Girdin and PI3K proteins. Univariate and multivariate analyses indicated that the co-expression of Girdin and PI3K proteins correlated with histological type, metastatic nodes and distant metastasis (P=0.01, 0.001 and 0.001, respectively). After analyzing survival rates, cases with Girdin and PI3K co-expression were shown to attain a significantly increased distant metastasis rate and poorer postoperative, disease-specific survival compared to those with Girdin and PI3K co-expression (P=0.001). In the Cox regression test, Girdin and PI3K co-expression was detected as an independent prognostic factor (P=0.001). Girdin may regulate the biological behavior of breast cancer via the PI3K/Akt/mTOR pathway, and thus, serve as a potential new target for breast cancer treatment.

    ABSTRACT: BACKGROUD: isoAsp-Gly-Arg (isoDGR) is a derivative of the Asn-Gly-Arg (NGR) motif, which is used as a targeted delivery tool to aminopeptidase N (CD13) positive cells. Recent studies have shown that cyclic isoDGR (CisoDGRC) has a more efficient affinity with α(v)β(3), a type of integrin that overexpresses in tumor cells. Antimicrobial peptides (AMPs) are an efficient antitumor peptide that specifically kills tumor cells. In the present study, we designed antimicrobial peptides containing the CisoDGRC motif (CDAK) and assessed its antitumor activity for CD13(-)/α(v)β(3) (+) breast cancer cells (MCF-7 and MDA-MB-231) in vitro and in vivo. IN VITRO: We assessed the cytotoxicity of CDAK for MCF-7 and MDA-MB-231 breast cancer cells, the human umbilical vein endothelial cell (HUVEC), and human foreskin fibroblasts (HFF). We performed an apoptosis assay using Annexin-V/PI, DNA ladder, mitochondrial membrane potential, and Caspase-3 and Bcl-2. The effect on cell cycles and affinity with cell were tested using flow cytometry and fluorescent microscopy and the effect on invasion was analyzed using an invasion assay. CDAK was injected intravenously into tumor-bearing athymic nude mice in vivo experiment. CDAK showed cytotoxic activity in MCF-7 and MDA-MB-231 cells, whereas HUVEC and HFF were less sensitive to the peptides. CDAK induced apoptosis, reduced mitochondrial membrane potential, promoted Caspase-3, and inhibited Bcl-2 expression in the two breast cancer cell lines. In addition, CDAK inhibited proliferation of cancer cell through S phase arrest, and own selective affinity with MCF-7 and MDA-MB-231cells, inhibited the invasion of MDA-MB-231 cells. In vivo, CDAK significant inhibited the progression of the tumor and the generation of neovascularization. Antimicrobial peptides containing the CisoDGRC (CDAK) motif could efficiently exhibit the antitumor activity for CD13(-)/α(v)β(3) (+) breast cancer cells.

    ABSTRACT: Seven years ago, a 48-year-old female patient discovered a painless tumor in her right breast simply by chance. In the next year, the tumor increased significantly in size. At this point, the patient received a tumor resection, which was misdiagnosed as a benign mesenchymal tissue-originated tumor. Unfortunately, the tumor recurred just 10 days after resection. We subsequently resected the recurrent lesion and confirmed primary breast malignant fibrous histiocytoma. The tumor began to exhibit an unprecedented, massive, and uncontrolled growth, ulcerating soon after the operation. Treatment of the patient was limited by time. After the patient received a cycle of chemotherapy, she died of cachexia with the emergence of multiorgan metastasis 2 months after the operation.

    ABSTRACT: Vascular endothelial growth factor receptor-1 (VEGFR-1 or Flt-1), a tyrosine kinase receptor, is highly expressed in breast cancer tissues, but near absent in normal breast tissue. While VEGFR-1 expression is associated with poor prognosis of women with breast cancer, it is not clear whether it is involved in the aggressiveness of breast cancer. Thus, the present study examined whether VEGFR-1 activation is associated with the invasiveness of breast cancer. We reported that VEGFR-1 was detected in 60.6% of invasive breast carcinoma tissue sections. In addition, VEGFR-1 expression positively correlated with lymph node-positive tumor status, low expression level of membranous E-cadherin, and high expression levels of N-cadherin and Snail. We found that PlGF-mediated VEGFR-1 activation promoted migration and invasion in MCF-7 (luminal) cells and led to morphologic and molecular changes of epithelial-mesenchymal transition (EMT). This was blocked by the down-regulation of VEGFR-1. Conversely, down-regulation of VEGFR-1 in MDA-MB-231 (post-EMT) cells resulted in morphologic and molecular changes similar to mesenchymal-epithelial transition (MET), and exogenous PlGF could not reverse these changes. Moreover, VEGFR-1 activation led to an increase in nuclear translocation of Snail. Finally, MDA-MB-231 cells expressing shRNA against VEGFR-1 significantly decreased the tumor growth and metastasis capacity in a xenograft model. Histological examination of VEGFR-1/shRNA-expressing tumor xenografts showed up-regulation of E-cadherin and down-regulation of N-cadherin and Snail. These findings suggest that VEGFR-1 may promote breast cancer progression and metastasis, and therapies that target VEGFR-1 may be beneficial in the treatment of breast cancer patients.

    ABSTRACT: PURPOSE: To investigate the association of the CD44+/CD24- cancer stem cell (CSC) ratio with clinicopathologic features and its prognostic value in breast cancer. Materials and Methods: The CD44+/CD24- CSC ratio was determined in formalin-fixed, paraffin-embedded breast cancer tissues from 1350 breast cancer patients by double immunofluorescence staining. The Cox regression analysis was performed to evaluate whether the CD44+/CD24- CSC ratio is an independent prognostic factor. The Kaplan-Meier survival analysis was conducted to determine the association of the CD44+/CD24- CSC ratio with cancer-specific survival. Results: The mean average CSC ratio in clinical specimens was 8.06% (range from 1.02% to 37.54%). The CD44+/CD24- CSC ratio, together with histological grade, molecular type, and clinical stage, was independent prognostic factors of breast cancer. The CD44+/CD24- CSC ratio was significantly correlated with estrogen receptor (ER), progesterone receptor (PR), and Ki67, but not the Her-2 and P53 status. Furthermore, the CD44+/CD24- CSC ratio was significantly associated with 5-year breast cancer-specific survival in 1242 cases (88.97% vs. 75.76% vs.52.11% for ≤ 5%, 5%-10% and >10% CSC ratio cases, respectively, p=0.001). The linear regression analysis showed that the CSC ratio was borderlinely correlated with the N stage related (R=0.397 p=0.06), and significantly correlated with distant recurrence (R=0.487, p=0.01) in 1350 specimens. After the survival analysis, the 5-year distant recurrence rates were (57/435 [13.10%] vs. 159/594 [26.77%] vs. 114/213 [53.52%] for ≤ 5%, 5%-10%, and >10% CSC ratio cases, p=0.001). Conclusion: The CSC ratio was an independent prognostic factor for breast cancer as well as a potential predictive marker for chemotherapy in breast cancer.

    ABSTRACT: OBJECTIVES:: The purpose of this study was to evaluate the outcome of the ratio between metastatic and examined lymph nodes (N ratio) in gastric cancer patients with <15 examined lymph nodes after curative resection. METHODS:: A retrospective study of 710 patients who underwent radical gastrectomy (R0) for gastric cancer from January 1980 to December 2000 was analyzed statistically to identify the N ratio. Patients with <15 examined lymph nodes (group 1, n=327) and those with ≥15 examined lymph nodes (group 2, n=383) were analyzed separately. N ratio categories were identified as follows: N ratio 0, 0%; N ratio 1, 1% to 9%; N ratio 2, 10% to 25%; and N ratio 3, >25%. All the enrolled categories were evaluated by the best cutoff approach. RESULTS:: The univariate analysis showed that age, tumor site, tumor size, surgery, T categories, number of metastatic nodes, and N ratio significantly affected prognosis in groups 1 and 2. By multivariate analysis, the N ratio (but not the TNM N category) classification was retained as an independent prognostic factor in groups 1 and 2 compared with the N category system. However, patients with N1 disease in group 1 obtained a better postoperative prognosis than those with N1 disease in group 2 according to the N stage classification (P=0.003). When the N ratio classification was applied, no significant differences were found for N ratios 0, 1, 2, or 3 between the 2 groups (P>0.05). CONCLUSIONS:: The metastatic lymph node ratio is an independent prognostic factor regardless of the examined number of lymph nodes. In predicting the prognosis of gastric cancer, the staging system based on the metastatic lymph node ratio is more reliable than the system based on the number of metastatic lymph nodes regardless of the examined number of lymph nodes. This can help improve the TNM staging classification of gastric cancer and reduce the International Union Against Cancer N categories of stage migration.

    ABSTRACT: We investigated the expression status of periostin in breast cancer stem cells and its clinical implications in order to lay a foundation for managing breast cancer. CD44+/CD24-/line- tumor cells (CSC) from clinical specimens were sorted using flow cytometry. Periostin expression status was detected in CSC cells and 1,086 breast cancer specimens by Western blot and immunohistochemistry staining, with the CSC ratio determined by immunofluorescence double staining. The relationship between the periostin protein and clinico-pathological parameters and prognosis was subsequently determined. As a result, CSC cells are more likely to generate new tumors in mice and cell microspheres that are deficient in NOD/SCID compared to the control group. Periostin protein was expressed higher in CSC cells compared to the control cells and was found to be related to CSC chemotherapy resistance. Moreover, periostin expression was found to be related to the CSC ratio in 1,086 breast cancer specimens (P = 0.001). In total, 334 (30.76%) of the 1,086 breast cases showed high periostin expression. After universal and Spearman regression correlation analysis, periostin was observed to be related to histological grade, CSC ratio, lymph node metastasis, tumor size, and triple-negative breast cancer (all P<0.05). Furthermore, periostin was shown to attain a significantly more distant bone metastasis and worse disease-specific survival than those with none or low-expressed periostin protein (P = 0.001). In the Cox regression test, periostin protein was detected as an independent prognostic factor (P = 0.001). In conclusion, periostin was found to be related to the CSC and an independent prognostic factor for breast cancer. It is also perhaps a potential target to breast cancer.

    ABSTRACT: The aim is to investigate the clinical implications of the Oct-4 and Nestin protein in human breast cancers. A total of 346 cases including 26 fresh and 320 paraffin-embedded tumor tissues were selected for characterizing the frequency of CD44(+)CD24(-) tumor cells by flow cytometry and the differential expression of the stem cell-related genes between CD44(+)CD24(-) and non-CD44(+)CD24(-) tumor cells was analyzed by PCR Array and immunofluorescence. In comparison with the non-CD44(+)CD24(-) tumor cells, the CD44(+)CD24(-), particularly for those with high percentage of Oct-4(+) and Nestin(+), tumor cells had higher tumorigenicity by forming mammospheres in vitro. More importantly, 42 (13.125%) out of 320 tumor tissues were positive for Oct-4 and Nestin staining. Universal analysis and multivariate analysis revealed that the expression of Oct-4 and Nestin was associated significantly with younger age, pathogenic degrees, lymph node metastasis and triple-negative breast cancer independently (P < 0.05) as well as shorter survival (P = 0.001). Oct-4 and Nestin were important regulators of the development of breast cancer, and Oct-4 and Nestin may be used as predictors for the prognosis of breast cancers.

    ABSTRACT: To investigate the expression status and the clinical implications of Girdin protein in breast cancer. The expression status of Girdin protein and clinicopathological parameters in 820 breast cancer specimens was analyzed using immunohistochemistry staining and the relationship between Girdin protein and clinicopathological parameters. The prognosis of breast cancer was subsequently determined. Girdin protein was expressed positively in 295 (35.98%) of the 820 cases examined. The expression of Girdin protein was related to histological type and CerbB2 (P = 0.001, 0.006, and 0.001, respectively). After analyzing survival rates, the cases with highly expressed Girdin protein were shown to attain a significantly more distant metastasis rate and poorer postoperative, disease-specific survival than those with none or low expressed Girdin protein (P = 0.001). In the Cox regression test, Girdin protein was detected as an independent prognostic factor (P = 0.031). Girdin protein may be a potential new distant metastasis biomarker of breast cancer.
