TranscriptomicsTriplication of a 21q22 region contributes to B cell transformation through HMGN1 overexpression and loss of histone H3 Lys27 trimethylation [RNA-Seq]
Down syndrome (DS) confers a 20-fold increased risk of B cell acute lymphoblastic leukemia (ALL), yet the mechanisms underlying this association are undefined.  We show that triplication of only 31 genes orthologous to the putative DS Critical Region (DSCR) on chr.21q22 is sufficient to promote B ce...

GenomicsTriplication of a 21q22 region contributes to B cell transformation through HMGN1 overexpression and loss of histone H3 Lys27 trimethylation [ChIP-seq]
Children with Down syndrome (DS) have a 20-fold increased risk of developing B cell acute lymphoblastic leukemia (B-ALL). Polysomy 21 (i.e., extra copies of chr.21) is also the most frequent somatic aneuploidy among all B-ALLs. Additional B-ALLs harbor intrachromosomal amplifications of chr.21q22 (i...

TranscriptomicsPolyploidy can drive rapid adaptation in yeast
Analysis of copy number variation in evolved haploid, diploid, tetraploid strains. All experimental samples were compared to the same reference strain S288C. The samples include the progenitor strains for the haploid, diploid, and tetraploid evolution experiments, and single colony isolates (clones...
