Regulation of NUMB alternative splicing by RBM5, RBM6 and RBM10 controls cancer cell proliferation

ABSTRACT: RBM5, a regulator of alternative splicing of apoptotic genes, and its close homologues, RBM6 and RBM10, are RNA binding proteins frequently deleted or mutated in lung cancer. We report that RBM5/6 and RBM10 antagonistically regulate the proliferative capacity of cancer cells and display distinct positional effects in alternative splicing regulation. We identify the Notch pathway regulator NUMB as a key target of these factors in the control of cell proliferation. NUMB alternative splicing, which is frequently altered in lung cancer, can regulate colony and xenograft tumor formation and its modulation recapitulates or antagonizes the effects of RBM5, 6 and 10 in cell colony formation. RBM10 mutations identified in lung cancer cells disrupt NUMB splicing regulation to promote cell growth. Our results reveal a key genetic circuit in the control of cancer cell proliferation. RNA from 3 biological replicates of knockdowns of RBM5, 6 and 10 and a control set were used. Changes between the control and knockdowns were measured based on using a splice-junction array (Affymetrix HJAY).

RBM5, a regulator of alternative splicing of apoptotic genes, and its highly homologous RBM6 and RBM10 are RNA-binding proteins frequently deleted or mutated in lung cancer. We report that RBM5/6 and RBM10 antagonistically regulate the proliferative capacity of cancer cells and display distinct positional effects in alternative splicing regulation.

Project description:Alternative RNA splicing analysis in Hep3B cell cultured under 21% (N1,3,5) or 1.2% (H2,4,6) oxygen Hypoxia is a common characteristic of many solid tumors. The hypoxic microenvironment stabilizes hypoxia-inducible transcription factor 1? (HIF1?) and 2? (HIF2?) to activate gene transcription, which promotes tumor cell survival. 95% of human genes are alternatively spliced, producing RNA isoforms that code functionally distinct proteins. Thus, effective hypoxia response requires increased HIF target gene transcription as well as proper RNA splicing of these HIF target genes. However, it is unclear if and how hypoxia regulates RNA splicing of HIF target genes. This study determined the effects of hypoxia on alternative splicing (AS) of HIF and non-HIF target genes in Hep3B cells and characterized the role of HIF in regulating AS of HIF induced genes. The results indicated that hypoxia generally promotes exon inclusion for hypoxia-induced, but reduces exon inclusion for hypoxia reduced genes. Mechanistically, HIF activity, but not hypoxia per se is found to be necessary and sufficient to increase exon inclusion of several HIF target genes including pyruvate dehydrogenase kinase 1 (PDK1). PDK1 splicing reporters confirmed that transcriptional activation by HIF is sufficient to increase exon inclusion of PDK1 splicing reporter. In contrast, transcriptional activation of the PDK1 minigene by other transcription factor in the absence of endogenous HIF target gene activation fails to alter PDK1 RNA splicing, demonstrating a novel role of HIF target gene(s) in regulating RNA splicing of HIF target genes. Implications:This study demonstrates a novel function of HIF in regulating RNA splicing of HIF target genes. We analyzed total RNA from Hep3B cells cultured under 21% (N1,3,5) or 1.2% (H2,4,6) oxygen using the Affymetrix Human Exon 1.0 ST platform. Array data was processed by Altanalyze software version 2.0.7. Techinical replicates were performed for Nx and Hx treated Hep3B cells

Project description:Alternative splicing analysis of laser micro-dissected lung dysplasia RNA samples Lung dysplasia is a precancerous condition with high risk of malignant transformation. Little is known about alternative spliced (AS) genes in dysplasia. We therefore investigated laser micro-dissected microscopic foci of non-contaminant dysplasia and/or lung adenocarcinoma of c-Raf transgenic mice and searched genome wide for AS genes using exon arrays. Notably, bioinformatics defined 34 and 36 AS genes in the comparison dysplasia versus transgenic unaltered and non-transgenic lung tissue while the comparison adenocarcinoma versus transgenic unaltered and non-transgenic lung tissue revealed 54 and 56 genes, respectively. So far only 6 of these were reported for lung cancer. Importantly, dysplasia related AS genes were also regulated in lung cancer to suggest a role in disease onset. Next to exon skipping/inclusion alternative splicing at the 3M-bM-^@M-^Y and 5M-bM-^@M-^Y was common and included genes of the splicing regulatory pathway. Disease dependent changes of variant transcripts were confirmed by RT-PCR while Western blotting identified alternative splicing to modulate protein levels of AS genes. For the AS genes Add3, Cast, Osbpl6, Nedd4l, Numb, Picalm and Slk transcript and protein level agreed well, whereas for Arhgef11, Clstn1, Dlg1, Dock9, Mbnl2, Mfge8, Npnt, Pdlim5, Ppp2r5c, Tjp1 notable differences in the abundance of variant transcripts were observed by RT-PCR and gel electrophoresis. Moreover, expression of individual variants differed between dysplasia and carcinoma to suggest their disease dependent regulation. Western blotting of IQGAP1, MYO6, PTPRM, RABGAP1L and RAD50 confirmed significant regulation of isoforms in lung cancer as compared to non-transgenic, transgenic unaltered and dysplastic lung tissue. For 46 AS genes expression of the non-variant protein was reported in human lung cancer (www.proteinatlas.org) and for 13 of these, cancer related AS events are known. Overall, new insight into lung dysplasia was obtained with 43 new cancer related AS genes to aid diagnosis and molecular intervention strategies. We analyzed and compared dysplastic (n=4) and adenocarcinoma (n=4) lesions and with transgenic but unaltered (n=4) and non-transgenic (n=5) lung tissue obtained from SPC/c-Raf transgenic mice with aid of laser micro dissection pressure catapulted (LMPC) technique. Dysplasia is a pre-neoplastic condition and developed at 5 month of age in the proposed mouse model. LMPC provides precise microscopic lesion collection without contamination. The RNA samples were analyzed using the Affymetrix Mouse Exon 1.0 ST platform. Alternative splicing was analyzed using Biotique XRAY tool. No technical replicates were performed.

Project description:The efficacy of cancer treatments have improved constantly in the last decade. However, therapeutic resistance and the lack of curative treatments in metastatic disease, raises the question if conventional anticancer therapies target the right cells. Indeed, these treatments might miss cancer stem cells (CSCs), which might also represent a more chemoresistant and radioresistant subpopulation within cancer. In this view using vaccines in tertiary prevention of cancer, i.e. residual disease treatment, might be particularly effective if vaccine-elicited immune response is directed against CSC oncoantigens (OAs) M-bM-^@M-^T proteins required for the neoplastic process M-bM-^@M-^T the chance that the tumour will evade the vaccine should be reduced. An important task to devise effective CSC preventive vaccines is therefore the identification of CSC OAs. In this experiment we used a cell line (TuBo) derived by the mouse breast cancer model BALB-neuT and its CSC subpupolation, enriched by mean of mammosphere formation. Integrating data derived by gene and exon-level transcription profiling of the above experiments with public available normal and tumor datasets we identified two new breast cancer CSC OAs: TMPRSS4 and xCT. Both genes are linked to invasion, migration and metastasis. Furthermore, we observed that alternative splicing events discriminating TuBo cells, grown in adherent medium, with respect of TuBo mammospheres, produced growing in no-adherent medium, are very limited. We detect only one clear splcing event characterizing the beta-isoform of Rabgap1l gene. This SuperSeries is composed of the SubSeries listed below. The adherent TuBo epithelial cells were generated from a mammary carcinoma arising in a BALB/c mouse female transgenic for the activated rat ErbB2 oncogene (BALB-neuT) and were cultured in DMEM supplemented with 20% FCS. Single TuBo cells were plated in ultra low attachment flasks in serum-free DMEM-F12 medium supplemented with bFGF, EGF and insulin. Nonadherent spherical clusters of cells, named mammospheres, were collected by gentle centrifugation after 7 days and dissociated enzymatically and mechanically, using trypsin and pipetting, respectively.
