Project description:We collected five DMG, five GBM (including two secondary GBM), and one peritumor samples from eleven patients requiring surgical resection. To establish an atlas for spatially-resolved gene expression, we performed short-read spatial transcriptomic sequencing on the tissue sections using the 10x Visium platform.
Project description:We carried out comprehensive analysis for the miRNA profiling of primary tumor and metastatic lesion which seems to be source of circulating miRNA. We picked up two patients who treated with primary tumor resection initially and received chemotherapy followed by surgical resection of liver metastasis. The total miRNA was isolated from frozen tissue specimens. SurePrint G3 Human miRNA microarray kit Rel.21.0 (Agilent Technologies) contains 2549 human microRNA probes. As previously reported, hsa-miR200c revealed specifically high expression in metastatic sites at both two cases.
Project description:We performed scATAC-seq on glioblastoma tissue samples taken at time of initial surgical resection to map the global chromatin profiles of glioblastoma cells and associated non-neoplastic cells
Project description:Gene expression profiles generated from human tumor cells laser-microdissected from surgical samples of seven choroid plexus papillomas (Grade I WHO) as eight samples of epithelial cells lasermicrodissected from normal choroid plexus obtained at autopsy. Choroid plexus tumors are rare pediatric brain tumors derrived from the choroid plexus epithelium. Gene expression profiles of lasermicrodissected tumor cells from 7 individual choroid plexus tumor samples obtained at surgery were compared to gene expression profiles from non-neoplastic choroid plexus epithelial cells lasermicrodissected from normal non-neoplastic choroid plexus obtained at autopsy (Am J Surg Pathol. 2006 Jan;30(1):66-74.) in order to identfy genes differentially expressed in choroid plexus tumor cells.

In two colorectal cancer patients, the frozen primary tumor, normal mucosa and liver-metastatic lesion were analyzed by microRNA microarray.
Project description:Uninvolved tissue taken at the time of primary surgical resection of an adenocarcinoma. Uninvolved status determined by surgical margin and gross appearance, not pathology
Project description:Glioblastomas are lethal cancers defined by inevitable disease recurrence after maximal surgical and chemoradiological interventions. To identify possible dependencies in glioblastomas undetected by whole transcriptome sequencing, we examined the enhancer landscape marked by histone 3 lysine 27 acetylation (H3K27ac) in primary glioblastoma specimens through ChIP-seq.
Project description:Epithelioid hemangioendothelioma (EHE) is a rare vascular sarcoma that is associated with a WWTR1-CAMTA1 fusion gene in greater than 90% of cases. We aimed to investigate the transcriptional pathways activated in EHE. Total RNA was isolated from EHE tumors from surgical resection or autopsy specimens (n=6) followed by RNA-Seq. The results of this study identified a unique transcriptional profile for EHE and helped to validate a novel murine model of EHE.
