Question

Quizplus · Accepted Answer

Protein kinase inhibitors directly target the intracellular cascade of reactions leading to proliferation and survival of cancerous cells. They work by inhibiting enzymes called protein kinases, which are involved in cell signaling pathways that regulate cell growth, division, and survival. By blocking these pathways, protein kinase inhibitors can slow or stop the growth of cancer cells. S-phase inhibitors, monoclonal antibodies, and radioactive samarium all have different mechanisms of action and do not directly target intracellular signaling pathways.
