Wnt signaling pathway is believed to be responsible for control over various types of stem cells and may act as a niche factor to maintain stem cells in a self-renewing state. Moreover, dysregulated Wnt signaling pathway is strongly associated with several diseases including cancer. Previously, we have shown that AF1q associates with a poor prognosis in leukemia, myelodysplastic syndromes, multiple myeloid, ovarian cancer, and breast cancer. Also, AF1q plays a pivotal role as an oncogene and metastasis enhancer in breast cancer via activation of Wnt signaling pathway. AF1q is highly expressed in stem cells, and this expression is diminished by differentiation. To understand the role of AF1q in stem-like population, we examined stem-like cells derived from breast cells which dysregulated Wnt signaling pathway by alteration of AF1q expression. The effect of Wnt signaling pathway by AF1q on EMT marker expression, stem cell marker expression, and sphere formation was determined. Activated Wnt signaling pathway by AF1q enriched stem-like population showed enhanced sphere formation ability. Interestingly, Wnt signaling pathway inhibitor, Quercetin, decreased the sphere formation in these cells. These results suggest that AF1q would have a role as an enhancer in generation of stem-like population through activation of Wnt signaling pathway.
