WNT pathway inhibitor pyrvinium pamoate inhibits the self-renewal and metastasis of breast cancer stem cells.
Acquisition of chemoresistance and metastatic phenotype are the major causes of breast cancer treatment failure and cancer-related mortality. Recently, a plethora of experimental and clinical studies points toward a central role of cancer stem cells (CSCs) in the chemoresistance and metastasis. In the present study, we demonstrated that pyrvinium pamoate (PP), an anthelmintic drug, inhibited pr...
متن کاملThe Antihelmintic Drug Pyrvinium Pamoate Targets Aggressive Breast Cancer
WNT signaling plays a key role in the self-renewal of tumor initiation cells (TICs). In this study, we used pyrvinium pamoate (PP), an FDA-approved antihelmintic drug that inhibits WNT signaling, to test whether pharmacologic inhibition of WNT signaling can specifically target TICs of aggressive breast cancer cells. SUM-149, an inflammatory breast cancer cell line, and SUM-159, a metaplastic ba...
متن کاملmiR205 inhibits stem cell renewal in SUM159PT breast cancer cells
miR205 has a dual activity, as tumor suppressor and as oncogene. Here we analyzed the impact of miR205 ectopic expression in the initial tumorigenic processes of SUM159PT, a triple negative breast cancer cell line with low endogenous levels of miR205. In SUM159PT, miR205 inhibited expression of its targets VEGFA, ErbB3, Zeb1, Fyn and Lyn A/B; it reduced cell proliferation, and Myc/cyclin D1 lev...
متن کاملWnt pathway regulation of embryonic stem cell self-renewal.
Embryonic stem cells (ESCs) can generate all of the cell types found in the adult organism. Remarkably, they retain this ability even after many cell divisions in vitro, as long as the culture conditions prevent differentiation of the cells. Wnt signaling and β-catenin have been shown to cause strong effects on ESCs both in terms of stimulating the expansion of stem cells and stimulating differ...
متن کاملThe Wnt/β-catenin pathway regulates self-renewal of cancer stem-like cells in human gastric cancer.
Cancer stem cells (CSCs) possess the ability of self-renewal and tumor initiation. Targeting key signaling pathways that are active in CSC self-renewal is one approach to cancer therapy. Abnormal activation of the Wnt/β-catenin pathway has been described in a wide variety of human cancers and in CSCs; however, the role of this pathway in gastric CSCs has not been reported. In our study, we inve...
