In several types of cancer, upregulation of phosphatidylinositol 3-kinase (PI3K)-Akt signaling facilitates tumor cell growth and inhibits apoptosis. Previous reports demonstrated that this pathway promotes growth, survival, and chemotherapy resistance in non-small cell and small cell lung cancer cells. But

Heparin-protein interactions are important in many physiological processes including angiogenesis, the growth of new blood vessels from existing ones. We have previously developed a highly angiogenic self-assembling gel, wherein the self-assembly process is triggered by the interactions between heparin and
