Ivy Glioblastoma Atlas project

This is the online help for the Ivy Glioblastoma Atlas Project web application.

The Ivy Glioblastoma Atlas Project is a foundational resource for exploring the anatomic and genetic basis of glioblastoma at the cellular and molecular levels. The project is organized into six studies that were designed to identify genes enriched in glioblastoma. Three of those studies were based on anatomic structures or features of glioblastoma and three were focused on putative cancer stem cells.

Ivy Glioblastoma Studies

Color Key

Study

Description

Anatomic Structures ISH Survey

Primary screen of 8 tumors with probes for 343 genes enriched in glioblastoma.

Anatomic Structures RNA-Seq

Screen of 5 structures (Leading Edge, Infiltrating Tumor, Cellular Tumor, Microvascular Proliferation, and Pseudopalisading Cells Around Necrosis) identified by H&E staining. A total of 122 RNA samples were generated from 10 tumors.

Anatomic Structures ISH for Enriched Genes

Subsequent screen of 29 tumors with probes for 37 genes enriched in glioblastoma structures identified in Anatomic Structures RNA-Seq Study.

Cancer Stem Cells ISH Survey

Primary screen of 16 tumors with probes for 55 genes enriched in putative cancer stem cells, resulting in a 20 probe reference set, which was then used in an extensive screen of 42 tumors.

Cancer Stem Cells RNA-Seq

Screen of 35 clusters of putative cancer stem cells identified by ISH with a 17 reference probe subset (validated in the Cancer Stem Cells ISH Survey). A total of 148 RNA samples were generated from 34 tumors.

Cancer Stem Cells ISH for Enriched Genes

Subsequent screen of 37 tumors with probes for 76 genes enriched in clusters of putative cancer stem cells identified in the Cancer Stem Cells RNA-Seq Study.
