This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The basic premise of what we're doing is to really demonstrate clinically what Dr. Iwakuma found out in the labthat the reason why there is a potential for an anticancer effect of statins is because they can lead to degradation of conformational p53-mutated proteins, she said. The Advanced Worksheet challenges students to explore these ideas in greater depth, including how p53 interacts with other molecules in the cell. Search for another form here.
