Summary (written by the submitters)
Glioblastoma (GBM) is defined by heterogenous and resilient cell populations that closely reflect neurodevelopmental cell types. While it is clear that GBM echoes early and immature cell states, identifying the specific developmental programs disrupted in these tumors has been hindered by a lack of high-resolution trajectories of glial and neuronal lineages.

Here, we delineate the course of human astrocyte maturation to uncover discrete developmental stages and attributes mirrored by GBM. We generated a transcriptomic and epigenomic map of human astrocyte maturation using cortical organoids maintained in culture for nearly two years. Through this approach, we chronicled a multi-phase developmental process orchestrated by a series of transcription factor and gene regulatory networks. Our time course of human astrocyte maturation includes a novel and molecularly distinct intermediate period that serves as a lineage commitment checkpoint upstream of mature quiescence. This intermediate stage acts as a site of developmental deviation separating IDH-wildtype neoplastic astrocyte lineage cells from quiescent astrocyte populations. Interestingly, IDH1-mutant tumor astrocyte lineage cells are the exception to this developmental perturbation, where immature properties are suppressed as a result of D2HG oncometabolite exposure. We propose that this defiance is likely a consequence of IDH1mt-associated epigenetic dysregulation and we identified biased DNA hydroxymethylation (5hmC) in maturation genes as a possible mechanism. Together, this study illustrates a novel cellular state aberration in GBM astrocyte lineage cells and presents new developmental targets for experimental and therapeutic exploration.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE276176_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1155638 and SRA study SRP530031. Searching any of these in the dataset finder brings you back here.
