C
ancer relapse has been an issue in oncology research for more than few decades but author hasn’t reached
at a solution yet. Their study aims at avoiding the recurrence by making conventional therapies more ef-
ficient with adjunct treatment. Cancer stem cells (CSCs) is the root cause for drug/chemo-resistance as these
cells have characteristic properties of stem cells, they are quiescent and are highly invasive. Recent research
article explored various chemical compounds though high-throughput screening which would selectively tar-
get CSCs. Salinomycin is the reported potent drug and we decided to further investigate the same. Colorectal
cell lines DLD1, SW620 and breast cancer cell lines MCF7, MDA-MB-231 cells were used for the study. These
cells were exposed repeatedly to radiation dosage or treated with IC50 concentration of 5-Flurouracil (5-FU)
to generate resistant cell line. Levels of stemness markers like SOX2, KLF4, OCT4 etc. and epithelial-to-mesen-
chymal (EMT) markers like Snail1, Zeb1, E-cadherin, N-cadherin etc., were observed and were compared with
that of untreated cells. There was a significant up regulation in stemness and EMT pathway at transcriptional as
well as at protein level which was evaluated through real-time PCR and western blot, immune cytochemistry
respectively. At as low concentration of salinomycin as 2µM, these markers were down regulated and function-
al assays like colony forming assay and flow cytometry analysis of CD133 and CD44-CSC markers corroborated
the same. Thus, salinomycin could be potent drug to target CSCs avoid secondary tumor formation. Further
understanding of the target mechanism could help us improve the current treatment method.
