DDX5 in colonic tumors

ABSTRACT: The Asp-Glu-Ala-Asp (DEAD)-box RNA binding protein, DDX5, is ubiquitously expressed in many cell types, yet its role in RNA metabolism and its downstream function in vivo has not been fully elucidated. In the intestine, DDX5 is highly expressed in the intestinal epithelial cell (IECs) and contributes to tumorigenesis. Here, we used a conditional mouse lines where DDX5 is knocked out in IECs upon Tamoxifen administration to uncover mechanisms underlying DDX5 functions in colon tumors.

Expression signatures of human HeLa cells with RNAi targetting A1 hnRNP, FUS, H hnRNP and p68-DDX5

Project description:Transcription profiling of human HeLa cells (cervical cancer cell line) transfected with a plasmid expressing shRNAs cloned into the pSuper expression vector compared to emprty vector negative controls for transfection. Four different RNA interference treatments targetted: A1 hnRNP (HNRNPA1, Heterogeneous nuclear ribonucleoprotein A1); FUS (fusion gene, involved in t(12;16) in malignant liposarcoma); H hnRNP (HNRNPH1); and p68 helicase (DDX5, DEAD (Asp-Glu-Ala-Asp) box polypeptide 5). Keywords: genetic modification Five-condition experiment, where HNRNPA1, FUS, HNRNPH1 and DDX5 gene product levels were inhibited by siRNA transfection and compared to transfection with the negative control (scrambled siRNA). Biological replicates: 2 of each of the first three treatments and 3 of the treatment against DDX5, all independently grown and harvested. No technical replicates were performed.

Alternative splicing signatures in apoptosis related genes of human HeLa cells with RNAi targeting p68 RNA helicase-DDX5

Project description:Alternative splicing profiling of apopotosis related genes in human HeLa cells (cervical cancer cell line) transfected with a plasmid expressing shRNAs targetting p68 helicase (DDX5, DEAD (Asp-Glu-Ala-Asp) box polypeptide 5) cloned into the pSuper expression vector compared to empty vector. Keywords: treated vs. untreated comparison; alternative splicing Two-condition experiment, where the p68 DDX5 gene product levels was inhibited by siRNA transfection and compared to transfection with the negative control (scrambled siRNA). Biological replicates: 2, all independently grown and harvested. A dye swapping technical duplicate was performed for each biological replicate. Samples were hybridized onto a 44290 feature array designed by ExonHit to detect splicing events in apopotosis related genes and manufactured by Agilent using in situ synthesis of oligonucleotides by SurePrint technology.

Spatial transcriptomic studies of the small intestine from WT and DDX5△IEC (KO) mice

Project description:DDX5, a DEAD box containing RNA binding protein, is involved in multiple aspects of RNA metabolism and is abundantly expressed in all subsets of the intestinal epithelial cells (IEC). Here, we characterized the DDX5-dependent transcriptome in the small intestine. In the DDX5△IEC tissue, we found that secretory IEC lineage progenitor containing spots (Atoh1hi and Sox4hi) had reduced expression of Pou2f3, a master regulator of a subset of IECs called tuft cells. As a result of the loss of Pou2f3 expression in the progenitors, DDX5△IEC tissue harbored lower number of tuft cell containing spots (Dclk1hi) compare to WT tissues.

Regulation of gene expression in undifferentiated spermatogonia by DDX5

Project description:The maintenance of spermatogenesis in adult males is dependent on a population of mitotic germ cells with self-renewal potential known as undifferentiated spermatogonia. Regulation of undifferentiated spermatogonia function is dependent on transcriptional and post-transcriptional mechanisms. We have identified an essential role for the RNA helicase DDX5 in undifferentiated spermatogonia through generation of a UBC-CreERT2;Ddx5flox/flox mouse model that allows tamoxifen-dependent Ddx5 ablation. To identify genes regulated by DDX5, we generated lines of cultured undifferentiated spermatogonia from these mice and treated cells with tamoxifen (TMX) to induce Ddx5 knockout or vehicle (VEH) as a control, and performed RNA-sequencing analysis to compare these conditions.

RIP-seq of DDX5 in rhabdomyosarcoma cells

Project description:Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma of childhood characterized by the inability to exit the proliferative myoblast-like stage. Here, we identified the DEAD box RNA helicase 5 (DDX5) as a potential therapeutic target to inhibit alveolar rhabdomyosarcoma (ARMS) growth. We show that DDX5 is overexpressed in alveolar RMS cells, demonstrating that its depletion drastically decreases ARMS viability and slows tumor growth in xenograft models. Mechanistically, we provide evidence that DDX5 functions upstream the G9a/AKT survival signalling pathway, by modulating G9a protein stability

DDX5 RNA interactome in cultured T cells

Project description:RAR-related orphan receptor gamma (ROR t)-expressing regulatory T (ROR t+ Treg) cells play pivotal roles in preventing T cell hyperactivation and maintaining tissue homeostasis, in part, by secreting the anti-inflammation cytokine interleukin 10 (IL-10). Here, we report that Hypoxia Induced Factor 1a (HIF1alpha) is the master transcription factor for *Il10* in ROR t+ Tregs. Interestingly, this critical anti-inflammatory pathway is negatively regulated by an RNA-binding protein DEAD box helicase 5 (DDX5). As a transcriptional corepressor, DDX5 restricts the expression of HIF1 and its downstream target gene *Il10* in ROR t+ Tregs. T cell specific *Ddx5* knockout (DDX5 T) mice have augmented ROR t+ Treg suppressor activities and are better protected from intestinal inflammation. Genetic ablation or pharmacologic inhibition of HIF1a restores enteropathy susceptibility in DDX5 T mice. The DDX5-HIF1 -IL-10 pathway is conserved in mice and humans. These findings reveal potential therapeutic targets for intestinal inflammatory diseases.
