ABCA1/ABCB1 Ratio Determines Chemo- and Immune-Sensitivity in Human Osteosarcoma

Abstract The ATP Binding Cassette transporter B1 (ABCB1) induces chemoresistance in osteosarcoma, because it effluxes doxorubicin, reducing the intracellular accumulation, toxicity, and immunogenic cell death induced by the drug. The ATP Binding Cassette transporter A1 (ABCA1) effluxes isopentenyl pyrophosphate (IPP), a strong activator of anti-tumor Vγ9Vδ2 T-cells. Recruiting this population Read more…

Hyaluronan hydrogel: An appropriate three-dimensional model for evaluation of anticancer drug sensitivity

Abstract The extracellular polysaccharide hyaluronan (HA) controls cell migration, differentiation and proliferation, and contributes to the invasiveness of human cancers. In order to investigate the sensitivity of cancer cells to antimitotic agents, we developed a cross-linked HA hydrogel, a three-dimensional matrix in which cells can invade and grow. We have Read more…
