Expansion of the eukaryotic proteome by alternative splicing
TLDR
It is now clear that the 'missing' information is in large part provided by alternative splicing, the process by which multiple different functional messenger RNAs, and therefore proteins, can be synthesized from a single gene.Abstract:
The collection of components required to carry out the intricate processes involved in generating and maintaining a living, breathing and, sometimes, thinking organism is staggeringly complex. Where do all of the parts come from? Early estimates stated that about 100,000 genes would be required to make up a mammal; however, the actual number is less than one-quarter of that, barely four times the number of genes in budding yeast. It is now clear that the 'missing' information is in large part provided by alternative splicing, the process by which multiple different functional messenger RNAs, and therefore proteins, can be synthesized from a single gene.read more

Interferon-Stimulated Genes: A Complex Web of Host Defenses
TL;DR: This review begins by introducing interferon (IFN) and the JAK-STAT signaling pathway to highlight features that impact ISG production and describes ways in which ISGs both enhance innate pathogen-sensing capabilities and negatively regulate signaling through the Jak-STAT pathway.

rMATS: Robust and flexible detection of differential alternative splicing from replicate RNA-Seq data
Shihao Shen,Juw Won Park,Zhi-xiang Lu,Lan Lin,Michael D. Henry,Ying Nian Wu,Qing Zhou,Yi Xing +7 more
TL;DR: A new statistical model and computer program, replicate MATS (rMATS), designed for detection of differential alternative splicing from replicate RNA-Seq data, which uses a hierarchical model to simultaneously account for sampling uncertainty in individual replicates and variability among replicates.

Complementary Sequence-Mediated Exon Circularization
TL;DR: It is demonstrated that exon circularization is dependent on flanking intronic complementary sequences in human introns and that alternative formation of inverted repeated Alu pairs can lead to alternative circularization, resulting in multiple circular RNA transcripts produced from a single gene.
