RNA-seq in HUVECs upon DDX24 knockdown

ABSTRACT: DEAD-box (DDX) RNA helicases play crucial roles in gene regulation by interacting with RNAs and influencing RNA fate and function. Previously, we have associated DDX24 with vascular development, but its precise role in RNA metabolism remains unclear. In this study, we demonstrate that DDX24 modulated endothelial cell functions by binding to and regulating mRNAs crucial for vascular morphogenesis and angiogenesis. These results establish a link between DDX24-dependent regulation of mRNA stability and endothelial cell function, providing novel therapeutic targets for angiogenesis.

irCLIP-seq of DDX24 in HUVECs

Project description:DEAD-box (DDX) RNA helicases play crucial roles in gene regulation by interacting with RNAs and influencing RNA fate and function. Previously, we have associated DDX24 with vascular development, but its precise role in RNA metabolism remains unclear. In this study, we demonstrate that DDX24 modulated endothelial cell functions by binding to and regulating mRNAs crucial for vascular morphogenesis and angiogenesis. We further identify DDX24-bound mRNAs in endothelial cells using crosslinking immunoprecipitation (CLIP) sequencing. Mechanistically, DDX24 facilitates the decay of the target mRNAs, such as CLEC14A and ERG, by recruiting the deadenylase complex CCR4-NOT. These results establish a link between DDX24-dependent regulation of mRNA stability and endothelial cell function, providing novel therapeutic targets for angiogenesis.

Anti-apoptotic and anti-oxidative effects of DDX24 through HO-1 transcriptional regulation

Project description:DEAD-box helicase 24 (DDX24) is a member of the DEAD-box protein family, which is essential for various aspects of RNA metabolism. DDX24 has been reported to play a role in ribosome biogenesis, transcription, and mRNA stability. Previous studies have implicated the functions of DDX24 in innate immunity, vascular malformation, cell growth, and cancer progression. Here, we describe a novel function of DDX24 in regulating the oxidative stress response and protecting cells from apoptosis. Our research revealed that DDX24 specifically regulates the expression of the heme oxygenase-1 (HO-1) gene, as determined by RNA sequencing analysis. HO-1 is responsible for degrading heme into carbon monoxide (CO), biliverdin, and ferrous ion (Fe2+), thereby exerting anti-apoptotic and anti-oxidative effects. We validated the regulation of HO-1 by DDX24 in both DDX24-depleted and DDX24-overexpressing HEK293 cells. Our findings indicate that DDX24 is involved in the induction of HO-1 expression under oxidative stress conditions. Importantly, DDX24 regulates the transcription of HO-1 instead of its mRNA stability, likely acting at the promoter and enhancer E1 region of the HO-1 gene. Furthermore, DDX24 depletion in HEK293T cells inhibits cell viability. DDX24 exerts both anti-apoptotic and anti-oxidative effects during oxidative stress. These results suggest that DDX24 plays a crucial role in protecting cells from oxidative stress-induced damage by regulating the transcription of HO-1.

i.e. RFX8 mediates DDX24 transcription in human hepatocellular carcinoma

Project description:Accumulating evidence suggests that DEAD-box proteins are essential in RNA metabolism and play pivotal roles in cancer progression. However, the mechanisms underlying how DDX24 drives hepatocellular carcinoma (HCC) remain largely unknown. In this study, we demonstrated that DDX24 was an oncogene and identified RFX8 as a DDX24 promoter-binding protein that transcriptionally upregulated DDX24 expression.

DEAD box RNA helicases are pervasive protein kinase interactors and activators

Project description:DEAD box (DDX) RNA helicases are a large family of ATPases, many of which have unknown functions. There is emerging evidence that besides their role in RNA biology, DDX proteins may stimulate protein kinases. To investigate if protein kinase-DDX interaction is a more widespread phenomenon, we conducted three orthogonal large-scale screens, including proteomics analysis with 32 RNA helicases, protein array profiling, and kinome-wide in vitro kinase assays. We retrieved Ser/Thr protein kinases as prominent interactors of RNA helicases and report hundreds of binary interactions. We extracted members of eleven protein kinase families, which bind to - and are stimulated by - DDX proteins, including CAMK, CDK, CK1, CK2, DYRK, MARK, NEK, PRKC, SPRK, STE7/MAP2K, and STE20/PAK family members. We identified MARK1 in all screens and validated that DDX proteins accelerate MARK1 catalytic rate. The findings indicate pervasive interactions between protein kinases and DEAD box RNA helicases and provide a rich resource to explore their regulatory relationships.
