A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Paper
The Ednrb-Aim2-AKT axis regulates neural crest-derived melanoblast proliferation during early developmentDevelopment (Cambridge, England) · 2024
Summary (written by the submitters)
Ednrb is specifically required to develop neural crest (NC) stem cell-derived lineages. However, it is still unknown why Ednrb signaling is only needed for the early development of melanoblasts in the skin and eye. We show that Ednrb is required for the proliferation of melanoblasts during early mouse development. To understand the mechanism of melanoblast proliferation, we found that the gene absent in melanoma 2 (Aim2) is upregulated in Ednrb-deficient NC cells by RNA-sequencing analysis.

Consequently, the knockdown or knockout of Aim2 partially rescued the proliferation of Ednrb-deficient melanoblasts. Conversely, the overexpression of Aim2 in melanoblasts suppressed their proliferation. We further show that Ednrb signaling could act through the microRNA miR-196b to block the suppression of melanoblast proliferation by Aim2 in primary NC cell cultures. These results reveal the Ednrb–Aim2–AKT axis in regulating melanocyte development and suggest that Ednrb signaling functions as a negative regulator of Aim2, which inhibits the proliferation of melanoblasts in early development. These findings uncover a previously unreported role for Aim2 outside the inflammasome, showing that it is a significant regulator controlling NC stem cell-derived lineage development.

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 GSE275956_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 PRJNA1153952 and SRA study SRP529657. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 10 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 10 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
