Elimination of Enhanced Thermal Resistance of Spheroid Culture Model of Prostate Carcinoma Cell Line by Inhibitors of Hsp70 Induction
... Furthermore, the spheroids showed a more significant resistance to hyperthermia compared to the monolayer cultures (p = 0.01). They also produced more Hsp70 than the monolayer cultures. Treatment of cells with quercetin reduced the Hsp70 level in both culture systems. However, with the reduced Hsp70 levels, thermal resistance of the spheroids showed a greater decrease ... the monolayers. Conclusion: The results suggest that the enhanced hyperthermia resistance mechanism of the spheroid cultures compared to that of the monolayer cultures can be attributed to spheroids' Hsp70 production.
