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

The m6A reader YTHDC1 and the RNA helicase DDX5 control the production of rhabdomyosarcoma-enriched circRNAs

Project description:N6-Methyladenosine (m6A) is well-known for controlling different processes of linear RNA metabolism. Conversely, its role in the biogenesis and function of circular RNAs (circRNAs) is still poorly understood. Here, we characterize circRNA expression in the pathological context of rhabdomyosarcoma (RMS), observing a global increase when compared to wild-type myoblasts. For a set of circRNAs, such an increase is due to the raised expression of the m6A machinery, which we also find to control the proliferation activity of RMS cells. Furthermore, we identify the RNA helicase DDX5 as a novel mediator of the back-splicing reaction and as a co-factor of the m6A regulatory network. DDX5 and the m6A reader YTHDC1 are shown to interact and to promote the production of a common subset of circRNAs in RMS. In line with the observation that YTHDC1/DDX5 depletion reduces RMS proliferation, our results provide proteins and RNA candidates for the study of rhabdomyosarcoma tumorigenicity.

RNA helicase DDX5 maintains cardiac function by regulating CamkIIδ alternative splicing [RIP-seq]

Project description:The cardiomyocyte-specific deletion of Ddx5 in mice resulted in heart failure characterized by diminished cardiac function, enlarged heart chambers, and heightened fibrosis. Proteomic analysis unveiled the involvement of DDX5 in RNA splicing within cardiomyocytes. Our study identified DDX5 as a regulator of the abnormal splicing of CamkIIδ, preventing the generation of CaMKIIδA. This isoform activates LTCC through serine phosphorylation of Cacna1c, disrupting Ca2+ homeostasis. Consistently, DDX5-depleted cardiomyocytes exhibited elevated intracellular Ca2+ transients and increased sarcoplasmic reticulum Ca2+ content.

Next Generation Sequencing Facilitates Quantitative Analysis of RNAs bound by DDX5 and RORgt in cultured T helper 17 cell [RIP-seq]

Project description:Purpose: The goals of this study are to compare RNAs bound by DDX5 and RORgt in cultured T helper 17 cell in wildtype background. Methods: Th17 mRNA profiles of 48hrs in vitro cultured T helper 17 cells from wild-type mice were generated by deep sequencing, using Illumina HighSeq. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: BurrowsâWheeler Aligner (BWA) and TopHat followed by CuffDiff. qRTâPCR validation was performed using SYBR Green assays. Results: Among the 3444 RefSeq non-coding RNAs and 46449 NONCODE non-coding RNAs, 2533 were found to be expressed in Th17 cells (FPKM>1). 210 of them were enriched in DDX5 pull-down and 119 of them were enriched in RORgt pull-down. Conclusions: Our study suggest that a subset of 31 ncRNAs were co-enriched in DDX5 and RORgt pull-down. DDX5 or RORgt-associated-RNA profiles of 48hr in vitro cultured Th17 from wild type (WT) mice were generated by deep sequencing using Illumina HighSeq

RIP-seq data for CCNT1

Project description:To demonstrate RIPSeeker program that is developed for RIP-seq analyses, we generated RIP-seq data corresponding to the protein CCNT1 in HEK293 cell line using standard RIP-seq protocols described in Zhao et al., (2010). We performed two in-house RIP-seq experiments both for CCNT1 in human HEK293 cells. Briefly, we generated tagged CCNT1 using a triple tag system that supports lentiviral stable expression and mammalian affinity purification (MAPLE) Mak et al (2010). The HEK293 cells stably expressing tagged CCNT1 was purified by M2 agarose beads, followed by RNA extraction by Trizol. The library synthesis was carried out according to the RIP-seq protocol described in Zhao et al., (2010) except that one of the two experiments was done with non-strand-specific sequencing.
