Research Abstract |
In naturally occurring floating cell mass (spheroids) caused by the high-density culture of a breast cancer cell line, expression of CD133 cancer stem cell marker is increased. Analysis of the gene expression pattern using the next generation sequencers, expression variation of genes involved in the TGF-beta and the Wnt signaling were detected. Increase of aldehyde dehydrogenase activity was also observed. Although, the spheroids are resistant to anti-cancer agents such as doxorubicin, phosphorylation of HER2 is enhanced, and showed a sensitivity of nM order for HER2 inhibitors, such as lapatinib and canertinib.
