Background: Berberine and Nano-curcumin are two herbal medicines with strong anti-cancer effects on tumor cells, but low toxicity on normal cells, when used alone. Breast cancer is known as the most common cancer in women and second deadly one. In this study, we evaluated the cytotoxicity effects of combination Berberine and Nano-curcumin in breast cancer cell line to see whether they have furt...
Breast cancer is the most common cancer in women and the second leading cause of cancer deaths in women. Over 90% of breast cancer deaths are attributable to metastasis. Our lab has recently reported that AKT activates heat shock factor 1 (HSF1), leading to epithelial-to-mesenchymal transition in HER2-positive breast cancer. However, it is unknown whether the AKT-HSF1 pathway plays an important...
A cancer stem cell has been defined as a cell within a tumor that possesses the capacity to self-renew and to cause the heterogeneous lineages of cancer cells that comprise the tumor. These tumor-forming cells could hypothetically originate from stem, progenitor, or differentiated cells. Previously, we have shown that breast cancer cells with low metastatic potential can be induced into a rever...
The survival rate for women with advanced, metastatic breast cancer has not changed significantly for decades. Regardless of effective therapies, many women still experience recurrences of breast cancer after treatment. Chemotherapy with docetaxel (and other anti-cancer reagents) is widely used for the treatment of breast cancer. Despite an initial response to treatment, the sensitivity to anti...
Increasing evidence suggests that lineage specific subpopulations and stem-like cells exist in normal and malignant breast tissues. Epigenetic mechanisms maintaining this hierarchical homeostasis remain to be investigated. In this study, we found the level of microRNA221 (miR-221) was higher in stem-like and myoepithelial cells than in luminal cells isolated from normal and malignant breast tis...
Purpose: Breast cancer stem cells have been shown to be associated with resistance to chemotherapy in vitro, but their clinical significance remains to be clarified. The aim of this study was to investigate whether cancer stem cells were clinically significant for resistance to chemotherapy in human breast cancers. Experimental Design: Primary breast cancer patients (n = 108) treated with neoad...
Recently, the inflammatory cytokine IL-6 has been reported as a potent inducer of epithelial-mesenchymal transition (EMT) in breast cancer cells with an epithelial phenotype. Furthermore, EMT induces stem cell features in normal and transformed mammary cells. We explored whether IL-6-induced EMT promoted the generation of breast cancer stem-like c...
It has been proposed that the epithelial-mesenchymal transition (EMT) in mammary epithelial cells and breast cancer cells generates stem cell features. WISP2 (Wnt-1-induced signaling protein-2) plays an important role in maintenance of the differentiated phenotype of estrogen receptor-positive breast cancer cells and loss of WISP2 is associated with EMT. We now report that loss of WISP2 in MCF7...
Abstract Background: Taking into account the resistance of cancer cells to chemical drugs and considering the various reports on the effects of plants from the genus Artemisia for the cure of various ailments and diseases, this investigation was undertaken to compare the cytotoxic effects of different plant organs collected from low and high altitudes. In this study the cytotoxicity of metha...
