Identificación de empalme alternativo y poliadenilación en datos de RNA-seq

Overview

This study addresses the complexity of alternative splicing (AS) and alternative polyadenylation (APA) in gene expression regulation. Using bioinformatic protocols to analyze RNA sequencing data, the research highlights the advantages of both exon-based and event-based methods for detecting and visualizing alternative splicing and polyadenylation across different experimental conditions.
