Description
Medulloblastoma is the most frequent malignant pediatric brain tumor and is divided into at least four subgroups known as Wnt, SHH, Group 3 and Group 4. Here we characterized gene regulation mechanisms in the most aggressive subtype, Group 3 tumors, through genome-wide chromatin and expression profiling. Our results show that most active distal sites in these tumors are occupied by the transcription factor OTX2. Highly active OTX2 bound enhancers are often arranged as clusters of adjacent peaks and are also bound by the transcription factor NEUROD1. These sites are responsive to OTX2 and NEUROD1 knockdown and could also be generated de novo upon ectopic OTX2 expression in primary cells, showing that OTX2 cooperates with NEUROD1 and plays a major role in maintaining and possibly establishing regulatory elements as a pioneer factor. Among OTX2 target genes we identified the kinase NEK2, whose knockdown and pharmacological inhibition decreased cell viability. Our studies thus show that OTX2 controls the regulatory landscape of Group 3 medulloblastoma through cooperative activity at enhancer elements and contributes to the expression of critical target genes. Overall design: Primary Group 3 Medulloblastomas tumor samples were analyzed by RNA-seq. Group 3 medulloblastoma cell line (D341) was analyzed by RNA-seq. OTX2 was depleted by infection with lentiviral shRNAs (sh OTX2 and sh GFP control). Raw data not provided for primary Medulloblastoma samples due to patient privacy concerns. Submitter states that the raw data for these samples will be submitted to dbGaP.

Description
Tumor-stromal communication within the microenvironment contributes to initiation of metastasis and may present a therapeutic opportunity. Using serial single cell RNA-sequencing in an orthotopic mouse prostate cancer model, we find upregulation of Prolactin receptor as cancer cells that have disseminated to the lung expand into micrometastases. Secretion of the ligand Prolactin by adjacent lung stromal cells is induced by tumor cell production of the COX-2 synthetic product prostaglandin E-2 (PGE-2). PGE-2 treatment of fibroblasts activates the nuclear orphan receptor NR4A (Nur77), with Prolactin as a major transcriptional target for the NR4A-Retinoid X receptor (RXR) heterodimer. Ectopic expression of Prolactin receptor in mouse cancer cells enhances micrometastasis, while treatment with the COX-2 inhibitor Celecoxib abrogates Prolactin secretion by fibroblasts and reduces tumor initiation. Across multiple human cancers, COX-2, Prolactin, and Prolactin receptor show consistent differential expression in tumor and stromal compartments. Such paracrine crosstalk may thus contribute to the documented efficacy of COX-2 inhibitors in cancer suppression. Overall design: Primary tumors were established by direct prostate inoculation into immunosuppressed NSG mice of CE1-4 prostate cancer cells, derived from tissue-specific inactivation of PTEN [Pubmed ID: 20631921]. These cells, which were GFP-luciferase tagged, are noteworthy in that they have preserved expression of the androgen receptor and epithelial markers and recapitulate biological features of human prostate cancer. Six weeks following intra-prostate inoculation, multiple single DTCs were identified microscopically within the lungs (394 cells/hpf), with a smaller number in liver (54 cells/hpf), brain (9 cells/hpf) and bone marrow (1 cell/hpf). To undertake RNA sequencing of single cells during progression from quiescent DTCs to proliferative lesions, we identified GFP-tagged single tumor cells from lung harvested at various intervals, analyzing these separately from microdissected multicellular lesions. Individual DTCs collected at 6-7 weeks (DTC-I; N=20) and at 9-11 weeks (DTC-II; N=55) were compared with single cells derived from the primary tumor (N=29), lung micro-metastases (N=33), and CTCs isolated by microfluidic capture from blood specimens (N=12) [Pubmed ID: 28181495].
