resistance of CD44+CD24- breast cancer cells Abstract Fulltext Metrics Get Permission Authors Phuc PV, Nhan PLC, Nhung TH, Tam NT, Hoang NM, Tue VG, Thuy DT, Ngoc PK Published 21 June 2011 Volume 2011:4 Pages 71—78 DOI http://doi.org.secure.sci-hub.bz/10.2147/OTT.S21431 Review by Single-blind Peer reviewer comments Pham Van Phuc, Phan Lu Chinh Nhan, Truong Hai Nhung, Nguyen Thanh Tam, Nguyen Minh Hoang, Vuong Gia Tue, Duong Thanh Thuy, Phan Kim Ngoc Laboratory of Stem Cell Research and Application, University of Science, Vietnam National University, Ho Chi Minh, Vietnam Background: Cells within breast cancer stem cell populations have been confirmed to have a CD44+CD24- phenotype Strong expression of CD44 plays a critical role in numerous types of human cancers CD44 is involved in cell differentiation, adhesion, and metastasis of cancer cells Methods: In this study, we reduced CD44 expression in CD44+CD24- breast cancer stem cells and investigated their sensitivity to an antitumor drug The CD44+CD24- breast cancer stem cells were isolated from breast tumors; CD44 expression was downregulated with siRNAs followed by treatment with different concentrations of the antitumor drug Results: The proliferation of CD44 downregulated CD44+CD24- breast cancer stem cells was decreased after drug treatment We noticed treated cells were more sensitive to doxorubicin, even at low doses, compared with the control groups Conclusions: It would appear that expression of CD44 is integral among the CD44+CD24- cell population Reducing the expression level of CD44, combined with doxorubicin treatment, yields promising results for eradicating breast cancer stem cells in vitro This study opens a new direction in treating breast cancer through gene therapy in conjunction with chemotherapy Keywords: antitumor drugs, breast cancer stem cells, CD44, CD44+CD24- cells, doxorubicin This work is published and licensed by Dove Medical Press Limited The full terms of this
