A New Approach of Detecting Fusion Oncogenes by RNA Sequencing Exon Coverage Analysis.

Cancers (Basel)

November 2024

Institute for Personalized Oncology, World-Class Research Center "Digital Biodesign and Personalized Healthcare", I.M. Sechenov First Moscow State Medical University, 119991 Moscow, Russia.

Background: In clinical practice, various methods are used to identify gene rearrangements in tumor samples, ranging from "classic" techniques, such as IHC, FISH, and RT-qPCR, to more advanced highly multiplexed approaches, such as NanoString technology and NGS panels. Each of these methods has its own advantages and disadvantages, but they share the drawback of detecting only a restricted (although sometimes quite extensive) set of preselected biomarkers. At the same time, whole transcriptome sequencing (WTS, RNAseq) can, in principle, be used to detect gene fusions while simultaneously analyzing an incomparably wide range of tumor characteristics.

Long-term high-fat diet (HFD) promotes the formation of excess body weight and disorders of lipid metabolism and causes persistent dysbiotic changes in the intestinal microbial community. Changes in eating behavior, endocrine and immune functions of the host are associated with changes in the structure and functional activity of microbial communities. Short-term HFD may also influence the composition and function of the intestinal microbiota, but data on this issue are limited, and most papers are focused on the study of the large intestinal microbiota.

Introduction: The differential ratio of nonsynonymous to synonymous nucleotide substitutions (dN/dS) is a common measure of the rate of structural evolution in proteincoding genes. In addition, we recently suggested that the proportion of transposable elements in gene promoters that host functional genomic sites serves as a marker of the rate of regulatory evolution of genes. Such functional genomic regions may include transcription factor binding sites and modified histone binding loci.
