Article Abstract
For several decades there has been accumulating evidence implicating type I interferons (IFNs) as key elements of the immune response. Therapeutic approaches incorporating different recombinant type I IFN proteins have been successfully employed to treat a diverse group of diseases with significant and positive outcomes. The biological activities of type I IFNs are consequences of signaling events occurring in the cytoplasm and nucleus of cells. Biochemical events involving JAK/STAT proteins that control transcriptional activation of IFN-stimulated genes (ISGs) were the first to be identified and are referred to as "canonical" signaling. Subsequent identification of JAK/STAT-independent signaling pathways, critical for ISG transcription and/or mRNA translation, are denoted as "non-canonical" or "non-classical" pathways. In this review, we summarize these signaling cascades and discuss recent developments in the field, specifically as they relate to the biological and clinical implications of engagement of both canonical and non-canonical pathways.

The plastid genome of the critically endangered Valeriana trinervis (= Centranthus trinervis) and insights from comparison with other Valeriana plastomes (Caprifoliaceae).

The first complete plastid genome of the critically endangered species Valeriana trinervis was sequenced, assembled and compared with other published Valeriana plastomes. In this study, we assembled the plastid genome of the critically endangered, endemic species Valeriana trinervis (= Centranthus trinervis) and compare it with all published plastomes of Valeriana. We found not only differences in the inverted repeats boundaries, in the type and abundance of repeats, but also similarities in codon usage and microsatellite numbers.

E3 ubiquitin ligases regulate the cellular proteome proteasome-dependent protein degradation; however, there exist limited studies outlining their non-canonical functions. RNA-binding ubiquitin ligases (RBULs) represent a subset of E3 ligases that harbour RNA-binding domains, making them uniquely positioned to function as both RNA-binding proteins and E3 ligases. Our initial microarray screen for E3 ligases from mouse cortical neural progenitor cells identified MEX3B, a known RNA-binding ubiquitin ligase, to be differentially expressed.

The RbFox RNA binding proteins regulate alternative splicing of genes governing mammalian development and organ function. They bind to the RNA sequence (U)GCAUG with high affinity but also non-canonical secondary motifs in a concentration dependent manner. However, the hierarchical requirement of RbFox motifs, which are widespread in the genome, is still unclear.

Mutations in Delta Like Non-Canonical Notch Ligand 1 (DLK1), a paternally expressed imprinted gene, underlie central precocious puberty (CPP), yet the mechanism remains unclear. To test the hypothesis that DLK1 plays a role in gonadotropin releasing hormone (GnRH) neuron ontogeny, 75 base pairs were deleted in both alleles of DLK1 exon 3 with CRISPR-Cas9 in human pluripotent stem cells (hPSCs). This line, exhibiting More than 80% loss of DLK1 protein, was differentiated into GnRH neurons by dual SMAD inhibition (dSMADi), FGF8 treatment and Notch inhibition, as previously described, however, it did not exhibit accelerated GNRH1 expression.

Cancer cells are exposed to diverse metabolites in the tumour microenvironment that are used to support the synthesis of nucleotides, amino acids and lipids needed for rapid cell proliferation. In some tumours, ketone bodies such as β-hydroxybutyrate (β-OHB), which are elevated in circulation under fasting conditions or low glycemic diets, can serve as an alternative fuel that is metabolized in the mitochondria to provide acetyl-CoA for the tricarboxylic acid (TCA) cycle. Here we identify a non-canonical route for β-OHB metabolism that bypasses the TCA cycle to generate cytosolic acetyl-CoA.
