Cellular Effects of Selected Unsymmetrical Bisacridines on the Multicellular Tumor Spheroids of HCT116 Colon and A549 Lung Cancer Cells in Comparison to Monolayer Cultures
Abstract
Multicellular tumor spheroids are a good tool for testing new anticancer drugs, including those that may target cancer stem cells (CSCs), which are responsible for cancer progression, metastasis, and recurrence. Therefore, we applied this model in our studies of highly active antitumor unsymmetrical bisacridines (UAs). We investigated the cellular response induced by UAs in 2D and 3D cultures of HCT116 colon and A549 lung cancer cells, with an additional focus on their impact on the CSC-like population. We showed that UAs affected the viability of the studied cells, as well as their spherogenic potential in the 2D and 3D cultures. Furthermore, we proved that the most promising UAs (C-2045 and C-2053) induced apoptosis in the HCT116 and A549 spheres to a similar, or even higher, extent than what was found in monolayer conditions. Next, we identified the population of the CSC-like cells in the 2D and 3D cultures of the studied cell lines by determining the levels of CD166, CD133, CD44, and EpCAM markers. We showed that the selected UAs affected the CSC-like population in both of the cell lines, and that A549 was affected more profoundly in 3D than in 2D cultures. Thus, the UAs exhibited high antitumor properties in both the 2D and 3D conditions, which makes them promising candidates for future therapeutic applications.
