    Enrichment of 3T3-HOX11 DPs by cDNA RDA. (A) Ethidium-stained agarose gel electrophoresis of starting cDNA Dpn II fragment representations and various RDA enriched populations obtained by mutual subtraction of NIH 3T3 cells (3T3) with 3T3-HOX11 (left lanes show products obtained with NIH 3T3 cells as the tester and right lanes show products obtained with 3T3-HOX11 cells as the tester). Tester representation (R; unselected cDNA) and DP1, DP2, DP3, and DP4 are shown. The arrow indicates an enriched HOX11 Dpn II fragment identified by Southern filter hybridization with a HOX11 -specific probe. (B) Southern filter hybridizations (with Slim1 , Aldh1 , HOX11 , and β- actin probes as indicated) of the agarose gel-fractionated RDA DPs shown in panel A. Fragment sizes are indicated. (C) Northern filter hybridization of 10 μg of total RNA prepared from untransfected NIH 3T3 cells and three independent 3T3-HOX11 clones and hybridized with HOX11 , Slim1 , Aldh1 , and ATP synthase probes (as indicated). 3T3-HOX11 clones 5 and 18 were found to express HOX11 protein, while clone 11 did not (data not shown). Hybridization of the filter with ATP synthase was used to assess the quality of the RNA transferred.

    Identification of mVIS. Strategy outline for identification of regions flanking DNA methylated viral integration sites (mVIS) within murine leukemias. Genomic DNA was digested with DpnII (step 1), followed by methylated DNA immunoprecipitation (MeDIP, step 2). MeDIP enriched fragments were ligated (step 3) and amplified using primers within the LTR (step 4). These fragments were hybridized on a DNA promoter array (step 5). Hypergeometric Analysis of Tiling Arrays (HAT) was used to identify regions flanking mVIS (step 6).

    MIAA identifies global influence of GC-content and differentially accessible motifs. A) GC-content observed to be correlated with accessibility in both stem and endoderm cells from positive (universally opening) and negative (universally closing) control sequences. B) GC-content correlated with accessibility in random DNA phrases. The regression model was trained on MIAA Dpn proportions with GC-content, replicate, and cell type-specific effects of 20 motifs and 26 motif pairs as features, and predicts well on (C) training data (n = 21,420) and (D) held-out test data (n = 4,404). The correlation reported is the Pearson correlation coefficient (r). E) Regression weights of individual motifs and motif pairs in stem and definitive endoderm cells. Hierarchical clustering of regression weights followed by motif enrichment recovers clusters representing cell type-specific transcription factor DNA binding motifs. F) Example of individual motifs (left, middle) which alone do not differentially open chromatin, but differentially open chromatin stem cells in combination (right). Each dot represents the average DpnII read proportion of an individual phrase, compared to shuffled controls (CTRL). Significance computed by paired t-test.

    Multiplexed Integrated Accessibility Assay (MIAA) measures local DNA accessibility of synthesized oligonucleotide phrase libraries. A) 100nt phrases are integrated into stem cells at a designated genomic locus. Stem cells are split and half are differentiated into definitive endoderm cells. Retinoic acid receptor fused to hyper-activated deoxyadenosine methylase (DAM) enzyme results in methylation of phrases that open DNA. DNA is extracted and half is exposed to DpnII, which cleaves unmethylated sequences, while half is exposed to DpnI, which cleaves methylated sequences. Sequences are PCR amplified and sequenced. B) DpnI and DpnII read counts measured from a single definitive endoderm replicate show difference between designed opening and closing phrases. C) Proportion of DpnII read counts measured from a single definitive endoderm replicate gives estimate of MIAA openness. D) 100nt native sequences that were differentially opening as measured by DNase-seq are differentially opening as measured by MIAA and different from randomly shuffled control sequences (significance measured by paired t-test). E) Differential accessibility as measured by log change in normalized DNase-seq reads and MIAA methylation proportion shows correlation between native differential accessibility and MIAA accessibility. The correlation reported is the Pearson correlation coefficient (r).
