Two distinct regions of minimal deletion (RMD) have been identified at 6q25-q27 in non-Hodgkin's lymphoma (RMD-1), and at 6q21-q23 in acute lymphoblastic leukemia (ALL; RMD-2) by loss of heterozygosity and fluorescence in situ hybridization studies. In this study, 30 overlapping yeast artificial chromosomes (YACs), 1 expressed sequence tag, and 11 novel YAC ends were identified using bidirectional YAC walks between markers D6S447 (proximal) and D6S246 (distal) in RMD-2. The genes AF6q21, human homologue of the Drosophila tailless (HTLX), CD24 antigen, the Kruppel-like zinc finger BLIMP1, and cyclin C (CCNC), previously mapped to 6q21, were accurately positioned in a telomere-to-centromere orientation. Approximately 3.5 Mb were found to separate the BLIMP1 (adjacent to D6S447) and AF6q21 genes (telomeric to D6S246). Deletions of 6q were investigated in 21 cases of ALL using the newly characterized YAC clones in dual-color fluorescence in situ hybridization studies. A region centromeric to D6S447 (containing marker D6S283) and a region telomeric to marker CHLC.GGAT16CO2 (and containing marker D6S268) were identified as distinct and nonoverlapping regions of deletion in ALL.

Chromosome 20q13.2 is amplified in 20-30% of early-stage breast tumors and is associated with poor prognosis. Detailed mapping of the amplified region using molecular cytogenetics, positional cloning and genomic sequencing culminated in a detailed molecular description of the candidate oncogene ZNF217. ZNF217 proteins resemble Kruppel-like transcription factors, localize predominately to the nucleus and associate with proteins involved in transcriptional repression. The findings that ZNF217 can immortalize human mammary epithelial cells and that its amplification is associated with poor prognosis suggest that it may play roles in both early- and late-stage breast cancer. We present evidence that ZNF217 can attenuate apoptotic signals resulting from telomere dysfunction as well as from doxorubicin-induced DNA damage and that silencing ZNF217 with siRNA restores sensitivity to doxorubicin. Moreover, elevated ZNF217 leads to increased phosphorylation of Akt, whereas inhibition of the phosphatidylinositol 3 kinase pathway and Akt phosphorylation decreases ZNF217 protein levels and increases sensitivity to doxorubicin. These results suggest that ZNF217 may promote neoplastic transformation by increasing cell survival during telomeric crisis and may promote later stages of malignancy by increasing cell survival during chemotherapy.
