AbstractTwo ATP-binding cassette transporters, ABCB1/MDR1 and ABCG2/BCRP, are considered the most critical determinants for chemoresistance in hepatocellular carcinoma. However, their roles in the chemoresistance in liver cancer stem cells remain elusive. Here we explored the role of inhibition of MDR1 or ABCG2 in sensitizing liver cancer stem cells to doxorubicin, the most frequently used chemotherapeutic agent in treating liver cancer. We show that the inhibition of MDR1 or ABCG2 in Huh7 and PLC/PRF/5 cells using either pharmacological inhibitors or RNAi resulted in the elevated level of intracellular concentration of doxorubicin and the accompanied increased apoptosis as determined by confocal microscopy, high-performance liquid chromatography, flow cytometry, and annexin V assay. Notably, the inhibition of MDR1 or ABCG2 led to the reversal of the chemoresistance, as evident from the enhanced death of the chemoresistant liver cancer stem cells in tumorsphere-forming assays. Thus, the elevation of effective intracellular concentration of doxorubicin via the inhibition of MDR1 or ABCG2 represents a promising future strategy that transforms doxorubicin from a traditional chemotherapy agent into a robust killer of liver cancer stem cells for patients undergoing transarterial chemoembolization.

<p>The present study demonstrates the effects of triptolide, one of the constituents from Tripterygium wilfordii, on the self‑renewal capacity of human hepatocellular carcinoma. The investigation revealed that triptolide markedly prevented the proliferation of liver cancer stem cells (LCSCs). For the LCSCs the minimum inhibitory concentration of triptolide was 0.6 μM. There was a significant and obvious decrease in the capacity of LCSCs to form self-sphere. Furthermore, triptolide reduced the sphere-forming capacity of LCSCs along with inhibition of β‑catenin expression. However, the exposure of triptolide-treated cells to lithium chloride, an activator the Wnt/β-catenin signaling pathway, reversed the triptolide-induced inhibition of β-catenin expression and inhibited the self-renewal capacity. Therefore, triptolide effectively eradicates LCSCs through the inhibition of β-catenin protein and may act as a novel agent for the treatment of hepatocellular carcinoma.</p><p> </p>
