Figure 7From: Doxorubicin loaded Polymeric Nanoparticulate Delivery System to overcome drug resistance in osteosarcoma Caspase-3/7 activity was measured as a second parameter of apoptotic cell death. KHOS (A) and KHOSR2 (B) showed significant increase in apoptosis when they were treated with doxorubicin loaded nanoparticle. The experiment was repeated three times in triplicate. P values are shown as follows: *P < 0.05.Back to article page
