Is treosulfan-induced apoptosis in acute myeloid leukemia cells accompanied by translocation of protein kinase C delta and enhanced by bryostatin-1?
Our data provide evidence for a strong antileukemic effect of treosulfan in both cell lines and AML blasts from patients at concentrations below the plasma levels described at standard dose levels. Furthermore, the proapoptotic effect of treosulfan is mediated at least in part by activation of PKC isoforms and can be augmented by coincubation with bryostatin-1.
Chronic CSC is associated with genetic variants in ARMS2 and CFH, indicating a genetic and pathophysiologic overlap between cCSC and AMD. Intriguingly, alleles in ARMS2 and CFH that confer risk of AMD may be protective for cCSC, and alleles in CFH that are protective for AMD confer risk for cCSC. Significant differences in allele frequencies were found among the phenotypic subgroups for several SNPs, illustrating the importance of correct clinical classification.
