SpletIntroduction. Tumor protein p53 ([TP53] p53, encoded by the human gene TP53) is a tumor suppressor protein, which is involved in transcriptional activation, DNA binding and oligomerization with other proteins.The functions of p53 are primarily in inducing cell cycle arrest, apoptosis, senescence, DNA repair, and changes in metabolism. 1,2 Somatic … SpletThis therapy leads to sustained disease control in most patients with high-risk CLL, independently of TP53 status. Krämer et al. report the results of the multicenter CLL3X trial by the German CLL Study Group (GCLLSG) which evaluated RIC allo-HCT in 90 patients with high-risk CLL. Blood stem cells from related donors were used in 40% of ...
