CD15s EXPRESSION IN DIFFERENT CD44CD24 BREAST CANCER CELL SUBPOPULATIONS AFTER THIENO[2,3-b]PYRIDINE TREATMENT

Depending to the extent of CD44/CD24 ratio in breast cancer cells, they are more related to cell proliferation and tumorigenesis then to metastasis. CD44+ CD24- cells are well known as cancer stem cell subpopulation. Recently, three different breast CD44CD24 non-cancer stem cell subpopulations have been described as relevant for cancer proliferation and drug resistance: CD44- CD24+ and CD44- CD24- as epithelial, and CD44+ CD24+ as hybrid cells with both mesenchymal and epithelial features. The aim of this study was to investigate novel anticancer compound 1, 3-amino-5-oxo-N-naphthyl- 5, 6, 7, 8- tetrahydrothieno[2, 3-b]quinoline-2-carboxamide, effect upon expression of CD15s, the ligand that enables cancer cell to metastasize, in three different triple negative breast cancer cell subpopulations. MDA-MB-231 triple negative breast cancer cells were incubated 48 h with compound 1 alone or in combination with paclitaxel. Flow cytometric analysis was performed to detect the number of cells in each subpopulation as well as their CD15s expression and percentage of each CD15s+ subpopulation. Compound 1 decreased the number of CD44- CD24+ cells but without statistical significance (p=0.123). CD44+ CD24+ subpopulation was halved (p=0, 021). Compound 1 lowered CD15s expression only in CD44- CD24+ epithelial cells. Treatment with paclitaxel was without effect. In addition to our previous findings of compound 1 effects in CD44+ CD24- cancer stem cells, this study proved its anticancer effects in CD44+ CD24+ and CD44- CD24+ breast cancer cell subpopulations, superior in relation to paclitaxel.
