Oncogenes

Description

This program discusses how the chemical alteration of oncogenes in human cells causes the growth of cancerous tumors. Toxic substances, radiation, viruses, and inherited genetic defects are examined as factors causing such alteration. The mechanisms by which the altered forms overrule normal cell regulation are illustrated through microscope views and computer animation. Specific information is provided on cell cycle, cell division, growth factors, receptors, protein kinase, phosphatase, G-proteins, transduction processes, src-, ras-, and raf-oncogenes, and signal transduction.
