Abstract

Cytogenetic investigations carried on 1021 cases of Down syndrome revealed translocation in 46 cases. The most frequent was of t(14;21) and t(21;21) types. Most of the translocation DS cases (n = 31) were born to younger mother's (< 25 years), when compared to pure trisomy 21 DS cases. Parental karyotypes, family history and parental ages has helped us greatly in offering genetic counseling, prenatal diagnosis and estimating the risk for the next conception.

The fusion protein AML1-ETO in acute myeloid leukemia with translocation t(8;21) induces c-jun protein expression via the proximal AP-1 site of the c-jun promoter in an indirect, JNK-dependent manner.

Overexpression of proto-oncogene c-jun and constitutive activation of the Jun N-terminal kinase (JNK) signaling pathway have been implicated in the leukemic transformation process. However, c-jun expression and the role of the JNK signaling pathway have not been investigated in primary acute myeloid leukemia (AML) cells with frequently observed balanced rearrangements such as t(8;21). In the present study, we report elevated c-jun mRNA expression in AML patient bone marrow cells with t(8;21), t(15;17) or inv(16), and a high correlation in mRNA expression levels of AML1-ETO and c-jun within t(8;21)-positive AML patient cells. In myeloid U937 cells, c-jun mRNA and protein expression increase upon inducible expression of AML1-ETO. AML1-ETO transactivates the human c-jun promoter through the proximal activator protein (AP-1) site by activating the JNK pathway. Overexpression of JNK-inhibitor JIP-1 and chemical JNK inhibitors reduce the transactivation capacity of AML1-ETO on the c-jun promoter and the proapoptotic function of AML1-ETO in U937 cells. An autocrine mechanism involving granulocyte-colony stimulating factor (G-CSF) and G-CSF receptor (G-CSF-R) might participate in AML1-ETO mediated JNK-signaling, because AML1-ETO induces G-CSF and G-CSF-R expression, and G-CSF-R-neutralizing antibodies reduce AML1-ETO-induced JNK phosphorylation. These data suggest a model in which AML1-ETO induces proto-oncogene c-jun expression via the proximal AP-1 site of the c-jun promoter in a JNK-dependent manner.

Haplotype block partition with limited resources and applications to human chromosome 21 haplotype data.

Recent studies have shown that the human genome has a haplotype block structure such that it can be decomposed into large blocks with high linkage disequilibrium (LD) and relatively limited haplotype diversity, separated by short regions of low LD. One of the practical implications of this observation is that only a small fraction of all the single-nucleotide polymorphisms (SNPs) (referred as "tag SNPs") can be chosen for mapping genes responsible for human complex diseases, which can significantly reduce genotyping effort, without much loss of power. Algorithms have been developed to partition haplotypes into blocks with the minimum number of tag SNPs for an entire chromosome. In practice, investigators may have limited resources, and only a certain number of SNPs can be genotyped. In the present article, we first formulate this problem as finding a block partition with a fixed number of tag SNPs that can cover the maximal percentage of the whole genome, and we then develop two dynamic programming algorithms to solve this problem. The algorithms are sufficiently flexible to permit knowledge of functional polymorphisms to be considered. We apply the algorithms to a data set of SNPs on human chromosome 21, combining the information of coding and noncoding regions. We study the density of SNPs in intergenic regions, introns, and exons, and we find that the SNP density in intergenic regions is similar to that in introns and is higher than that in exons, results that are consistent with previous studies. We also calculate the distribution of block break points in intergenic regions, genes, exons, and coding regions and do not find any significant differences.

Predicting human minisatellite polymorphism.

We seek to define sequence-based predictive criteria to identify polymorphic and hypermutable minisatellites in the human genome. Polymorphism of a representative pool of minisatellites, selected from human chromosomes 21 and 22, was experimentally measured by PCR typing in a population of unrelated individuals. Two predictive approaches were tested. One uses simple repeat characteristics (e.g., unit length, copy number, nucleotide bias) and a more complex measure, termed HistoryR, based on the presence of variant motifs in the tandem array. We find that HistoryR and percentage of GC are strongly correlated with polymorphism and, as predictive criteria, reduce by half the number of repeats to type while enriching the proportion with heterozygosity >/=0.5, from a background level of 43% to 59%. The second approach uses length differences between minisatellites in the two releases of the human genome sequence (from the public consortium and Celera). As a predictor, this similarly enriches the number of polymorphic minisatellites, but fails to identify an unexpectedly large number of these. Finally, typing of the highly polymorphic minisatellites in large families identified one new hypermutable minisatellite, located in a predicted coding sequence. This may represent the first coding human hypermutable minisatellite.
