OBJECTIVE To investigate whether inhibition of Akt phosphorylation by the phosphatidylinositol 3-kinase (PI3K) inhibitor, wortmannin, reduces metastasis and angiogenesis in a human breast cancer cell line via nuclear factor (NF)-κB-dependent matrix metalloproteinase (MMP)-9 and interleukin (IL)-8 pathways. METHODS MDA-MB-231 cells were treated with(More)
It has been demonstrated that ganoderma acids suppress growth, angiogenesis and invasiveness of highly invasive and metastatic breast cancer cells in vitro and vivo. However, the mechanism of action of ganoderma acids in breast cancer remains unknown. In the present study, we looked into the effect of ganoderic acid Me (GA-Me) on cellular phenotypes and(More)
Protein tyrosine phosphatase non-receptor type 12 (PTPN12) is a recently identified tumor suppressor gene (TSG) that is frequently compromised in human triple-negative breast cancer. In the present study, we investigated the expression of PTPN12 protein by patients with breast cancer in a Chinese population and the relationship between PTPN12 expression(More)
Breast cancer in young women younger than 35 years old is rare, aggressive and associated with a poor prognosis. Endocrine therapy is a preferred treatment modality in hormone receptor-positive early stage and advanced breast cancer, combined therapy of goserelin and letrozole presents an option for premenopausal women. We reported the efficacy and safety(More)
BACKGROUND Because tumorigenesis depends on a variety of oncogenes, symphyseal study of combined genes may lead to more significant knowledge about tumorigenesis and progression. Combined deficiency of p21 and p27 proteins in mice is linked to more aggressive spontaneous tumorigenesis. We investigated the effect of the transfected p21 (Waf1) -p27 (Kip1)(More)
Breast cancer is the most common malignancy among females throughout the world. Current treatments have unsatisfactory outcomes due to the dispersed nature of certain types of the disease. The development of a more effective therapy for breast cancer has long been one of the most elusive goals of cancer gene therapy. In the present study, human mesenchymal(More)
OBJECTIVE To explore the expression of miRNA-135b in a variety of breast cancer cell lines and its function on the proliferation, invasion and migration in triple-negative breast cancer cell lines by targeting adenomatous polyposis coli (APC). METHODS Quantitative real-time (RT)--PCR was used to detect the expression of miRNA-135b in seven breast cancer(More)
OBJECTIVE To elucidate the role of transforming growth factor-beta1(TGF-β1) in epithelial-mesenchymal transition of mesothelial cells and peritoneal metastasis of gastric cancer. METHODS HMrSV5 cells, a human peritoneal mesothelial cell line, were incubated with TGF-β1, and their morphological changes were observed by phase contrast microscopy.(More)
OBJECTIVE To establish human umbilical cord mesenchymal stem cells (HUMSCs) strain transfected with interleukin-18 (IL-18) gene and examine its effects on the proliferation of breast cancer cell (MCF-7). METHODS HUMSCs were isolated and cultured. And the lentivirus-IL-18 vector containing human IL-18 gene was constructed and transfected into HUMSCs. The(More)
The ability of immune system to react specifically against tumors inspirited the study of triple negative breast cancer (TNBC) immunotherapies. Sixty spontaneous breast cancer TA2 mice were randomly divided into three groups: GM-CSF group, with therapy of granulocyte-macrophage colony-stimulating factor (GM-CSF) combined with breast cancer stem cells(More)
