| Description | Ras-association domain family (RASSF) members are a family of genes containing an RA domain in either the C-terminus (RASSF1-RASSF6) or in the N-terminus (RASSF7-RASSF10). Members of this gene family are core members of the Salvador/Warts/Hippo (SWH) tumor suppressor network and have been shown to be involved in human tumorigenesis. Among the RASSF genes, RASSF1A is one of the most frequently methylated genes in a wide range of epithelial cancers, and we previously demonstrated that RASSF6 and RASSF10 genes are frequently epigenetically inactivated in acute leukemias, particularly in those of the B cell type. We here determined the methylation profiles of all members of the RASSF gene family as well as two recently identified (KIBRA, CRB3) upstream members of the SWH pathway in the leukemic B cells obtained from a well-characterized cohort of 95 patients with chronic lymphocytic leukemia (CLL). Among the RASSF genes, RASSF10 (50%) was the most frequently methylated gene, followed by RASSF6 (16%). The remaining RASSF genes were either unmethylated or showed a frequency of methylation < 10%. The upstream SWH member KIBRA was also frequently methylated in CLL (35%) in contrast to CRB3. Interestingly, the analysis of clinical-pathological parameters showed that KIBRA methylation was associated with unfavorable biological prognostic parameters, including unmutated IGHV genes (p = 0.007) and high CD38 expression (p < 0.05). |
