Cooperative adaptation to therapy (CAT) confers resistance in heterogeneous non-small cell lung cancer

ABSTRACT: To study the interaction between mutated clones using interspecies competition and mathematical models Methods: RNA was extracted from 3-D cultures after 48 hours of growth in spheroids using manufacturer protocol (Qiagen) and sequenced in duplicate using Illumina NextSeq500. libraries were prepared from 500ng of purified RNA using Illumina TruSeq preparation kits. Sequence reads that passed quality filters were aligned to the UCSC mm9 reference genome and quanitifed using STAR (v2.5.1b). Normalized read counts (FPKM) were calculated using cufflinks and transcriptome profiling was analyzed using DESeq2. We determined that previously sensitive cancer cell clones within heterogeneous tumors will induce drug resistant phenotypes among neighboring cells while under drug pressure Non-mutational drug resistance can arise through drug-induced mechanisms augmented in heterogeneous tumors.

RNA-seq profiling of parental and NLUCAT1-deleted A549 cells under hypoxia

Project description:Parental or NLUCAT1 CRISPR/Cas9-deleted A549 clones (WT A549 Hx, n = 1 clone; DEL A549 Hx, n = 1 clone) were exposed to hypoxia (Hx) at 1% O2 for 24 hours. Libraries were generated from 500 ng of total RNAs using TruSeq Stranded Total RNA kit with Ribo-Zero (Illumina) and sequenced on a NextSeq500 sequencer (Illumina) with 2x75bp paired-end chemistry. Reads were aligned to the human genome release hg19 using STAR v2.4.0a with default parameters.

Cell of origin epigenetic priming determines susceptibility to Tet2 mutation

Project description:Hematopoietic stem cell (HSC) mutations can result in clonal hematopoiesis (CH) with heterogeneous clinical outcomes. Here, we investigated how the cell state preceding Tet2 mutation impacts the pre-malignant phenotype. Using an inducible system for clonal analysis of myeloid progenitors, we found that the epigenetic features of clones at similar differentiation status were highly heterogeneous and functionally responded differently to Tet2 mutation. Cell differentiation stage also influenced Tet2 mutation response indicating that the cell of origin's epigenome modulates clone-specific behaviors in CH. Molecular features associated with higher risk outcomes include Sox4 that sensitized cells to Tet2 inactivation, inducing dedifferentiation, altered metabolism and increasing the in vivo clonal output of mutant cells, as confirmed in primary GMP and HSC models. Our findings validate the hypothesis that epigenetic features can predispose specific clones for dominance, explaining why identical genetic mutations can result in different phenotypes.

Whole-genome genotyping of human islets using Illumina infinium chips

Project description:Genomic DNA was extracted from human islets using Dneasy Blood & Tissue Kit (QIAGEN) with RNase A treatment. 200-500ng DNA was genotyped using InfiniumOmni2-5-8v Genotyping BeadChips (Illumina).DNA was isolated from human islet cells from various donors. DNA was genotyped using Illumina Infinium whole-genome genotyping array. Genotypes were called with GenomeStudio (v.2.0.4) using default settings. Genotypes that passed quality filters (missing<0.05, minor allele frequency (MAF>0.01), non-ambiguous alleles defined by AT/GC variants with MAF>40%) were exported.
