Members of the fibroblast growth factor receptor (FGFR) family have essential roles in normal physiology and in cancer where they control diverse processes. FGFRs have been associated with breast cancer development. Thus, models to study the role of FGFR in breast cancer and their targeting potential are important. We present an in vitro and in vivo analysis of FGFRs in the breast cancer model ...

Prognosis of metastatic breast cancer is very poor which urges the necessity to develop novel potential drug candidates. We assessed two compounds with tri-aryl structures (A and B) for their potency to reduce primary breast tumor growth and lung metastasis in 4T1 mice model. MTT assay, 4T1 mammary mouse model and immunohistochemistry experiments were used in this study. In vitro results exhibi...

BACKGROUND Lipocalin 2, an iron binding protein, is abnormally expressed in some malignant human cancers and may play an important role in tumor metastasis. However, the roles of lipocalin 2 in breast cancer formation and metastasis have not been clearly shown. This study aimed to investigate the roles of lipocalin 2 in breast tumor metastasis. METHODS Lipocalin 2 was overexpressed in the met...

The aim of the present study was to investigate the effect of matrine on breast cancer and its underlying mechanism. Matrine is a major component of Sophora flavescens, exhibited antitumor activity in a number of neoplasms, including breast cancer. The present study revealed that matrine inhibited cell viability and induced apoptosis in 4T1 and MCF-7 cells in a dose- and time-dependent manner i...

Porphyra dentata, an edible red macroalgae, is used as a folk medicine in Asia. This study evaluated in vitro and in vivo the protective effect of a sterol fraction from P. dentata against breast cancer linked to tumor-induced myeloid derived-suppressor cells (MDSCs). A sterol fraction containing cholesterol, β -sitosterol, and campesterol was prepared by solvent fractionation of methanol extra...

The strategies available for the treatment of metastatic breast cancer are limited. Dietary botanicals may have a better protective effect on this disease. We therefore investigated the effects of grape seed proanthocyanidins (GSPs) on a highly metastatic mouse mammary carcinoma cell line. In vitro treatment of breast cancer cells, 4T1, MCF-7 and MDA-MB-468, with GSPs resulted in significant in...

BACKGROUND Metastasis is the major cause of cancer related death and targeting the process of metastasis has been proposed as a strategy to combat cancer. Therefore, to develop candidate drugs that target the process of metastasis is very important. In the preliminary studies, we found that schisandrin B (Sch B), a naturally-occurring dibenzocyclooctadiene lignan with very low toxicity, could s...
