Figure Lengend Snippet: (A) Genome-wide matrix of topologically associated domains (TADs) shows that most interactions are intrachromosomal (diagonal intensity pattern indicates each chromosome plotted against itself). A unique interaction pattern between chromosomes 1p and 7q (black arrow) was observed in KT-47R1 but not in KT-47PT. (B) Hi-C identified an interchromosomal interaction between chromosome 1p32.3 ( GLIS1 locus) and chromosome 7q21 ( ABCB1 locus, black arrow) in KT-47R1. The light red vertical line marks the boundary between interacting regions of chromosomes 1 (right) and 7 (left). Red arcs indicate interactions between chromosomes 1 and 7 in KT-47R1, absent in KT-47PT (no blue arcs crossing the boundary). RNA-seq reads confirm upregulation of ABCB1 (black arrow) in KT-47R1. (C) CUT&Tag analysis shows H3K4me1 peaks within the interacting region of chromosome 1p32.3. Peaks are present in both KT-47PT and KT-47R1, but the chromatin interaction occurs only in KT-47R1. (D) FISH 1p32.3 break-apart analysis demonstrates no translocation involving 1p32.3 in KT-47PT, KT-47 pre-resistance, KT-47R1, or KT-47R2. Scale bars, 5 μm. (E) Chromosome 1 and 7 painting analysis indicated increased interaction (colocalization) between chromosomes 1 and 7 in KT-47R1 (48%) and KT-47R2 (48%) when compared to KT-47PT (19%) and KT-47PR (25%). Scale bars, 10 μm. n = 2 samples per group.
