Measurements of transcript isoform specific translation across the human genome reveal that isoforms from the same gene can differ in protein production by two orders of magnitude.
The Aire-dependent genes show a preference for short 3’UTR transcript isoforms resulting in the escape from the post-transcriptional repression mediated by miRNAs in medullary thymic epithelial cells.

ESRP1 is central to intestinal barrier integrity in mice and humans and alterations in ESRP1 function or expression contribute to intestinal pathology, partly through modified expression of ESRP1-specific GPR137 isoforms.

Delineation of the cuticular hydrocarbon biosynthetic pathway in malaria vectors is a key step in understanding how mosquitoes adapt to anthropogenic change and vector control interventions.
Cis-regulation such as enhancers and promoters plays a major role in parallel gene expression divergence and has features that make it a well-poised substrate for adaptive evolution.
New methods reveal that complex local splicing variations are more prevalent in animals than previously appreciated, and demonstrate that local splicing variations are relevant for studies of development, gene regulation and neurodegenerative diseases.

RNA polymerase II generates numerous transcript isoforms, including transcripts initiating downstream of the START codon, that are efficiently degraded by the nonsense-mediated mRNA decay pathway.
