Project description:Several members of SRSF family play wide-ranging roles in the regulation of transcription and post-splicing processes as well as splice sites selection. Although the expression of SRSF3 was reported to be overexpressed in several cancers, the roles of SRSF3 in the cancer cells are almost unknown. We analyzed differentially expressed genes in SRSF3 siRNA-treated HCT116 cells and identified the specific pathways regulated by SRSF3. After treatment of HCT116 cells with SRSF3 (sample 02) or control (sample 01) siRNA, total RNA was extracted using RNeasy Mini Kit (Qiagen, Valencia, CA). The quality of the purified RNA and its applicability for microarray analysis were assessed by the Agilent 2100 Bioanalyzer using a RNA 6000 Nano Labchip kit (Agilent Technologies, Palo Alto, CA, USA). Total RNA (400 ng) was used for amplification, labeling and hybridization to a whole human genome oligoDNA microarray (4x44k; Agilent) according to the manufacture’s instructions.

Project description:Signaling through the platelet-derived growth factor receptor alpha (PDGFRa) is critical for mammalian craniofacial development, though the mechanisms by which the activity of downstream intracellular effectors is regulated to mediate gene expression changes have not been defined. We find that the RNA-binding protein Srsf3 is phosphorylated at Akt consensus sites downstream of PI3K-mediated PDGFRa signaling in palatal mesenchyme cells, leading to its nuclear translocation. We further demonstrate that ablation of Srsf3 in the neural crest lineage leads to facial clefting due to defective cranial neural crest cell specification and survival. Finally, we show that Srsf3 regulates the alternative RNA splicing of transcripts encoding protein kinases in the facial process mesenchyme to negatively regulate PDGFRa signaling. Collectively, our findings reveal that PI3K/Akt-mediated PDGFRa signaling primarily modulates gene expression through alternative RNA splicing in the facial mesenchyme and identify Srsf3 as a critical regulator of craniofacial development.

Project description:TDP43 and SRSF3 has been reported to be RNA-binding proteins; however their roles in breast cancer progression has not been examined previously. Here, we performed RNA-seq on MDA-MB231 cells stably expressed sh-control, shTDP43, shSRSF3 or sh-TDP43 and sh-SRSF3 using lentivirus in duplicates. In addition, MDA-MB231 cells with stable expression of flag-TDP43 or flag-SRSF3 were also generated by using lentivirus. RIP-seq was also applied to identify binding RNA against Flag antibodies.

Project description:We profiled gene expression and splicing changes in HCC1806 human TNBC cells overexpressing three splicing factor genes (SRSF2-SRSF3-SRSF7), all three splicing factors (called 3xSR) or MYC. We performed RNA-seq, in triplicate on 3xSR, MYC-OE, triple plasmid control, SRFS2, SRSF3, SRSF7, or single plasmid control HCC1806 cells.

Project description:Serine-rich splicing factor 3 (SRSF3) was recently reported as being necessary to preserve RNA stability via an mTOR mechanism in a cardiac mouse model in adulthood. Here, we demonstrate the link between Srsf3 and mitochondrial integrity in an embryonic cardiomyocyte-specific Srsf3 conditional knockout (cKO) mouse model. Fifteen-day-old Srsf3 cKO mice showed dramatically reduced (below 50%) survival and reduced the left ventricular systolic performance, and histological analysis of these hearts revealed a significant increase in cardiomyocyte size, confirming the severe remodeling induced by Srsf3 deletion. RNA-seq analysis of the hearts of 5-day-old Srsf3 cKO mice revealed early changes in expression levels and alternative splicing of several transcripts related to mitochondrial integrity and oxidative phosphorylation. Likewise, the levels of several protein complexes of the electron transport chain decreased, and mitochondrial complex I-driven respiration of permeabilized cardiac muscle fibers from the left ventricle was impaired. Furthermore, transmission electron microscopy analysis showed disordered mitochondrial length and cristae structure. Together with its indispensable role in the physiological maintenance of mouse hearts, these results highlight the previously unrecognized function of Srsf3 in regulating the mitochondrial integrity.

Project description:Alternative polyadenylation (APA) refers to the regulated selection of polyadenylation sites (PASs) in transcripts, which determines the length of their 3’ untranslated regions (3’UTRs). APA regulates stage- and tissue-specific gene expression by affecting the stability, subcellular localization and translation rate of transcripts. We have recently shown that SRSF3 and SRSF7, two closely related SR proteins, connect APA with mRNA export. The mechanism underlying APA regulation by SRSF3 and SRSF7 remained, however, unknown. Here, we combined iCLIP, RNA-Seq and 3’-end sequencing to find that both proteins bind upstream of proximal PASs (pPASs), yet they exert opposite effects on 3’UTR length. We show that SRSF7 enhances pPAS usage in a concentration-dependent but splicing-independent manner by recruiting the cleavage factor FIP1, thereby generating short 3’UTRs. Protein domains unique to SRSF7, which are absent from SRSF3, and hypo-phosphorylation contribute to FIP1 recruitment. In contrast, SRSF3 promotes distal PAS (dPAS) usage and hence long 3’UTRs by maintaining high levels of cleavage factor Im (CFIm) via alternative splicing. Upon reduced expression of SRSF3, CFIm levels strongly decrease and 3’UTRs are globally shortened. In SRSF3-regulated transcripts, CFIm and FIP1 bind upstream of dPASs and promote their usage. Surprisingly, both factors are also recruited to pPASs under conditions where their usage is blocked, suggesting the formation of inactive cleavage complexes. Thus, we identify SRSF3 as a novel regulator of CFIm activity, provide evidence that CFIm inhibits pPAS usage and show that small differences in the domain architecture of SR proteins confer opposite effects on PAS selection.
