Project description:To examine the effects of SRp20 on genome-wide RNA splicing in tumor cells, we utilized Exonhit SpliceArray to compare genome-wide changes of RNA splicing and transcription in U2OS cells with or without knockdown of SRp20 by RNAi. U2OS cells were treated by SRp20 siRNA or non-specific siRNA, each performed in triplicate. A human genome-wide splice-array assay was performed by using a service provider ExonHit Therapeutics, Inc (Gaithersburg, MD). Fifty ng of total RNA isolated from U2OS cells with or without knockdown of SRp20 was quality controlled and analyzed by using Affymetrix GeneChip platform to profile the expression of 20,649 genes and splicing events of 19,066 genes.
Project description:We used RNA sequencing to identify the RBFOX1 splicing network at a genome-wide level in primary human neural stem cells during differentiation. We observe that RBFOX1 regulates a large set of alternative splicing events implicated in neurogenesis and cell maintenance. Subsequent alterations in gene expression define an additional transcriptional network regulated by RBFOX1 involved in neurodevelopmental pathways remarkably parallel to those affected by splicing.
Project description:TCERG1 is a highly conserved human protein implicated in interactions with the transcriptional and splicing machinery. To investigate TCERG1 function, we survey genome-wide changes in transcript and exon levels upon TCERG1 knockdown in HEK293T cells. Our data revealed that TCERG1 regulates different types of alternative spliced events, indicating a broad role in the regulation of alternative splicing.
