Expression profiling of DDX3X and DDX54 knockdown in MCF7 cells

Project description:We performed RNA-seq to observe the gene expression changes in cells following siRNA-mediated knockdown of DDX3X and DDX54 RNA helicases in human breast cancer MCF7 cells. Two siRNAs were used to target each RNA helicase and scramble siRNA-treated MCF7 cells were used as controls.

iCLIP of DDX3X and DDX54 in human breast cancer MCF7 cells

Project description:Individual nucleotide resolution cross-linking immunoprecipitation (iCLIP) detects protein-RNA binding sites at a single nucleotide resolution. We aimed to identify the transcripts directly bound to DDX3X and DDX54 in human breast cancer MCF7 cells and to characterize the site of interaction at a single nucleotide resolution.

ChIPseq of DDX3X, DDX54, ERalpha and H3K4me3 in human breast cancer MCF7 cells

Project description:We aimed to investigate the chromatin binding activity of DDX3X and DDX54 RNA helicases in human ER -dependent breast cancer MCF7 cells. We run a parallel chromatin binding profiling of ER ChIP-seq. H3K4me3 profiling was used as a quality control of the ChIP-seq procedure.

Medulloblastoma associated DDX3X mutants restore malignant potential of medulloblastoma cells decreased upon the loss of DDX3X expression

Project description:DDX3X is an ATP-dependent RNA helicase. Missense mutations in DDX3X gene are known to occur in WNT, SHH subgroup medulloblastomas. The role of DDX3X in medulloblastoma biology was studied by downregulating its expression in a SHH subgroup Daoy medulloblastoma cell line. DDX3X knockdown resulted in considerable reduction in proliferation, clonogenic potential and anchorage-independent growth of the medulloblastoma cells. Transcriptome analysis was performed to delineate the molecular mechanism underlying reduction in the malignant potential of the medulloblastoma cells upon DDX3X knockdown. Exogenous expression of three DDX3X missense mutants in the DDX3X knockdown cells could restore the malignant potential of the medulloblastoma cells.

Inhibiting DDX3X triggers tumor-intrinsic type I interferon response and enhances anti-tumor immunity

Project description:Accumulating evidence has shown that cellular double-stranded RNAs (dsRNAs) induce antiviral innate immune responses in human normal and malignant cancer cells. However, it is not fully understood how endogenous ‘self’ dsRNA homeostasis is regulated in the cell. Here, we show that an RNA-binding protein, DEAD-box RNA helicase 3X (DDX3X), prevents the aberrant accumulation of cellular dsRNAs. Loss of DDX3X induces dsRNA sensor-mediated type I interferon signaling and innate immune response in breast cancer cells due to abnormal cytoplasmic accumulation of dsRNAs. Dual depletion of DDX3X and a dsRNA-editing protein, ADAR1 synergistically activates the cytosolic dsRNA pathway in breast cancer cell. Moreover, inhibiting DDX3X enhances the antitumor activity by increasing tumor intrinsic-type I interferon response, antigen presentation, and tumor-infiltration of cytotoxic T cells as well as dendritic cells in breast tumors, which may lead to the development of breast cancer therapy by targeting DDX3X in combination with immune checkpoint blockade. To assess the impact of DDX3X on the gene expression in the breast cancer, we stably depleted DDX3X in breast cancer MCF7 cells using a short hairpin RNA (shRNA)-mediated knockdown, and performed a genome-wide transcriptome analysis using a next-generation RNA deep sequencing.
