Chronic lymphocytic leukaemia (CLL) results from the accumulation of apoptosis-resistant clonal B cells that are arrested in G0/G1, and is heterogeneous with respect to clinical outcome. An aggressive form of the disease is identified by an impaired p53 response to ionizing radiation (IR). This is associated with inactivating mutations of either p53 or ATM, a regulator of p53 activated by IR-induced DNA damage. Since other forms of DNA damage activate p53 via ATR, a kinase closely related to ATM ...[more]
