ADARs are RNA editing enzymes that catalyze the deamination of adenosine to inosine in double-stranded RNAs. In mammals, there are two isoforms of ADAR1 including a p110 isoform, which is constitutively and ubiquitously expressed, and a p150 isoform regulated by an IFN-inducible promoter. The mutation in ADAR1 gene causes Aicardi-Goutieres syndrome (AGS), a severe autoimmune disease in human. Furthermore, the significant decrease in RNA-editing activity was found in the p150 isoform mutant associated with AGS. In this study, we will perform transcriptome-wide analysis and identify the targets of ADAR1p150 isoform.

View SamplesTIA1 and TIAL1 encode a family of U-rich-sequence-specific mRNA-binding proteins (mRBPs) ubiquitously expressed and conserved in metazoans. By PAR-CLIP, we determined that both proteins bind target sites with identical specificity in 3' UTRs as well as within introns proximal to 5' and 3' splice sites. Double knockout (DKO) of TIA1 and TIAL1 increased target mRNA abundance proportional to the number of binding sites and impacted the accumulation of aberrantly spliced mRNAs including the dsRNA-binding protein PRKRA, whose expression was completely blocked and subsequently triggered the activation of the dsRNA-activated protein kinase EIF2AK2/PKR and stress granule formation. Ectopic expression of PRKRA cDNA or knockout of EIF2AK2 in DKO cells rescued this phenotype. Perturbation of maturation and/or stability of additional targets also compromised cell cycle progression. Our study reveals the essential role of a single mRBP family contributing to fidelity of mRNA maturation, translation and RNA stress sensing pathways in human cells.

View SamplesStudies in human innate lymphoid cell (ILC) development are important in understanding the pathophysiology of immune deficiencies and providing insights into the design of immunotherapies for patients with cancer, infection, and autoimmune disease. Currently, it is unclear where and how ILCs develop in humans. The overall goal of our study is to gain a comprehensive understanding of the cellular and molecular components that regulate human ILC development and function in order to best understand how they work in physiological and pathological states.

View SamplesBased on the pkl dP mutant phenotype, it is predicted that PKL plays a key role in regulating GA-responsive genes that are important for vegetative growth and phase transitions. To test this hypothesis, global transcriptome analysis was performed by RNA-Seq using shoots of 13d-old ga1-13 and ga1-13 pkl that were mock-treated or 10 µM GA3-treated for 24 h.
