MYC dosage compensation is mediated by miRNA-transcription factor interactions in aneuploid cancer
Summary We hypothesize that dosage compensation of critical genes arises from systems-level properties for cancer cells to withstand the negative effects of aneuploidy. We identified several candidate genes in cancer multiomics data and developed a biocomputational platform to construct a mathematical model of their interaction network with micro-RNAs and transcription factors, where the property of dosage compensation emerged for MYC and was dependent on the kinetic parameters of its feedback interactions with three micro-RNAs. These circuits were experimentally validated using a genetic tug-of-war technique to overexpress an exogenous MYC, leading to overexpression of the three microRNAs …
<i>MYC</i> Dosage Compensation is Mediated by miRNA-Transcription Factor Interactions in Aneuploid Cancer
Cancer complexity is consequence of genomic instability leading to aneuploidy. We hypothesize that dosage compensation of critical genes arise from systems-level properties for cancer cells to withstand the negative effects of aneuploidy. We developed a computational platform to identify a network of miRNAs and transcription factors interacting with candidate dosage-compensated genes using NCI-60 multi-omic data. We next constructed a mathematical model where the property of dosage compensation emerged for MYC and STAT3 and was dependent on the kinetic parameters of their feedback and feed-forward interactions with four miRNAs. We developed a genetic tug-of-war approach by overexpressing an…
