Integrated analysis of post-transcriptional regulations reveals insights into acute myeloid leukemia.

ABSTRACT: Post-transcriptional regulations play crucial roles in gene expression, but their global impact in acute myeloid leukemia (AML) remains poorly understood. Here, we perform an integrative analysis of transcriptomic and proteomic data from 44 AML samples to uncover the determinants of protein-to-mRNA-ratios (PTRs), a metric summarizing post-transcriptional regulatory processes. Using over a thousand proxies related to mRNA sequestration, translation efficiency, and RNA/protein stability, multivariate regression reveals key features driving PTRs. Our findings show that PTRs are conserved between AML samples and human tissues, underscoring the universality of underlying mechanisms. Furthermore, we show that the shadow proteome, consisting of genes frequently undetectable by mass spectrometry,
