Sufu and Spop cooperate to suppress SHH medulloblastoma tumorigenesis via regulation of Gli2 protein stability [ChIP-seq]

Project description:GLI2 overexpression is a hallmark in SHH subgroup of medulloblastoma (SHH MB). Here we identify the targetome of Gli2 in two mouse models of SHH MB: SmoM2 overexpression and Sufu;Spop double knockout MB.

Olig2 targetome in SHH subgroup of medulloblastoma

Project description:Several basic helix-loop-helix (bHLH) transcription factors are upregulated in Sonic Hedgehog subgroup of medulloblastoma (SHH MB). Olig2, a neural bHLH transcription factor known to regulate differentiation of neural cell populations, is broadly expressed in mouse models of SHH MB. ChIP-Seq of Olig2 revealed its binding to a large number of sites near genes known to promote SHH MB tumorigenesis, suggesting a potential role for Olig2 in regulating transcriptional programme of MB.

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.

Single-cell RNAseq of childhood medulloblastoma

Project description:We explore cellular heterogeneity in 28 childhood medulloblastoma (MB) (1 WNT, 9 SHH, 7 GP3 and 11 GP4) using single-cell RNA sequencing (scRNA-seq), immunohistochemistry and deconvolution of bulk transcriptomic data. Neoplastic cells are broadly clustered according to subgroup, and within subgroups discrete sample clustering is associated with chromosomal copy number variance. Each subgroup contains subpopulations exhibiting mitotic , undifferentiated and neuronal differentiated transcript profiles , corroborating other recent medulloblastoma scRNA-seq studies and identifying new subpopulations. We identify a photoreceptor-differentiated subpopulation that is predominantly found in GP3 medulloblastoma, and in SHH, a subpopulation that constitutes differentiating nodules . Deconvolution of a large transcriptomic dataset shows that neoplastic subpopulations are associated with major and minor subgroup subdivisions, for example, photoreceptor subpopulation cells are more abundant in GP3-alpha. This scRNA-seq dataset also demonstrates medulloblastoma subgroup-specific differences in the tumor microenvironment and immune landscape, and reveals an SHH nodule -associated myeloid subpopulation. Additionally, we perform scRNA-seq on genetically engineered mouse (GEM) models of GP3 and SHH medulloblastoma. These models specifically matched the corresponding human subgroup-specific neoplastic subpopulations. We provide an interactive online resource that facilitates exploration of these MB single cell datasets. Collectively, our findings advance our understanding of the neoplastic and immune landscape of the main medulloblastoma subgroups in both humans and GEM models.

scRNA-seq analysis of SHH medulloblastomas in Gfap-Cre/SmoM2 mice treated with CT-179 or Pox-resiquimod

Project description:Our parallel studies have shown that the OLIG2 inhibitor CT-179 and the TLR7/8 agonist resiquimod delivered in polyoxazoline nanoparticle (Pox-resiquimod) produce significant anti tumor effects when administered to mice with SHH medulloblastoma. To gain insight into the cellular events set in motion by each treatment, we compared sets of replicate mice with SHH medulloblastomas treated with either CT-179 or POx-resiquimod to a common set of untreated control mice with SHH medulloblastoma.

Identification of genes involved in SHH subgroup medulloblastoma using murine whole-body Sleeping Beauty insertional mutagenesis

Project description:Ptch+/- mice, which are predisposed to SHH subgroup medulloblastoma, were mutagenised using the Sleeping Beauty transposon to identify genes which increase the frequency of medulloblastoma formation. Gene expression in tumours was assessed both to investigate their relationship to human subgroup tumours, and to identify genes where expression was altered by mutagenesis. Total RNA isolated from tumours induced by SB mutagenesis were compared to normal cerebellum, tumours induced witout SB mutagenesis, and tumours from a distinct model of disease (GTML).
