Project description:We have employed single cell RNA sequencing using the 10x Genomics platform to study the molecular mechanisms underlying resistance to treatment. In clinically relevant mouse models of G3 medulloblastoma, CT-guided fractionated radiotherapy was given to induce the clonal selection of radioresistant subpopulations. Comparison of recurrent and treatment naïve tumors revealed a prognostic gene expression signature reflective of radio-resistance.
Project description:Group 3 medulloblastoma is the most aggressive among the four medulloblastoma subgroups, with poor prognosis and early metastasis making treatment particularly challenging. The lack of an immune-competent mouse model has hindered effective in vivo testing of potential drugs and mechanisms. Given the prevalent MYC overexpression in Group 3 medulloblastoma, we developed a Group 3-like medulloblastoma mouse model in C57BL/6J mice by overexpressing MYC in the cerebellum of newborn pups. This model provides a valuable tool for studying Group 3 medulloblastoma more effectively.

Project description:PRTG+ve cells show high self renewability in Group 3 medulloblastoma tumors. To access the proteins differentially expressed in this subset of cells, we sorted PRTG+ve and PRTG-ve cells by surface staining with Anti-PRTG antibody from Gr3 medulloblastoma xenografts.

Project description:We evaluated changes in active and repressive histone modifications following the silencing of OTX2 in Group 3 medulloblastoma tumorspheres
