Project description:Transcriptomic and epigenomic profiling of matched CML diagnosis/remission samples revealed a reconfiguration of gene expression and DNA methylation at remission exhibiting patterns similar to those observed in healthy individuals. In contrast, alternative splicing retains chronic phase-like abnormal patterns. Most dramatic dissimilarities between remission and healthy control samples were observed in intron retention. While reduced DNA methylation around splice sites could explain increased intron retention at diagnosis, maintenance of high intron retention levels at remission has other causes, such as reduced splicing factor expression and histone modifications.
