ChemicalInductionofApoptosis
Chemical Induction of Apoptosis - 1 May 2001p53, p21WAF1, Myc, Bcl-2, Bax, Bcl-x and bak are among the proteins involved in the regulation of apoptosis. The agents and doses listed in the table below have all been used to induce apoptosis by scientists at Oncogene Research Products. Not every agent will induce apoptosis in every cell type. Depending on the agent chosen and the concentrations used, maximal induction o......閱讀全文
