Discuss how advances in cellular biology have enhanced technology in terms of cancer, drugs, AIDS, ...

Cellular biology deals with sell signaling pathways, such as signal transduction. Signal transduction is the process by which an extracellular signaling molecule activates a membrane receptor that in turn alters intracellular molecules creating a response. If we know how this works, we'll be able to trace which pathways cause cancer. Understanding the cellular mechanisms and interactions between cellular components is instrumental to the development of new effective drugs and vaccines. Protein-protein interaction network, involving many aspects of cellular biology, is important to systematically understand the biological mechanisms such as molecular mechanisms of metabolic or signal pathway and the construction of complexes.

Cellular biology is important because there are a few tricks that are used to focus the treatments on the cancer cells and minimize the killing of normal cells. Like he mentioned ^, the one distinguishing feature of cancer cells is their rapid growth - much faster than normal cells. So, most treatments are designed to affect only cells that are rapidly growing by disrupting cellular growth. If you remember all the stuff about mitosis - this is how all cells grow in number. If you can disrupt mitosis, you can stop cancer - radiation and most older chemotherapies work this way.

Yah! I got a flag of my native country!
