  Hepatocellular carcinoma (HCC) is typically advanced at presentation and doxorubicin is the chemotherapeutic agent most frequently used in chemoembolization. Tumor microenvironment contains many cell types, including platelets, as well as cytokines and growth factors, potentially capable of modulating doxorubicin actions. Insulin-like growth factor I (IGF1) and its receptor (IGF1-R) signaling is important in cellular proliferation and prevention of apoptosis and the acquisition of chemotherapy resistance. IGF1 is present in platelets, which have been shown to alter doxorubicin actions in HCC cells. The effects on growth and motility after IGF1 pre-treatment in doxorubicin-treated HCC cells were thus examined, as well as the IGF1-R downstream pathways, PI3/Akt and MAPK kinases. We found that IGF1 antagonized the doxorubicin-mediated decrease in cell growth and motility, as well as the .. View More»
