Summary (written by the submitters)
CD226 plays a vital role in NK cell cytotoxicity, interacting with its ligands on tumor targets. Acute myeloid leukemia (AML) cells have developed mechanisms to escape NK cell cytotoxicity, including inducing downregulation of CD226 on NK cells. Induced pluripotent stem cell -derived NK (iPSC-NK) cells offer an important source of standardized off-the-shelf NK cell therapy to treat AML patients.

In this study, we engineered iPSC-NK cells with CD226 to assess the ability of killing AML cells. iPSC-NK cells engineered with CD226 have a typical NK cell phenotype and demonstrate improved anti-AML activity and multiple cytokines releasing at low effector-to-target ratios. Transcriptomic analysis revealed upregulation of immune effector function pathways associated with cytotoxicity and immune activation in CD226-overexpression iPSC-NK cells. In an AML xenograft model, mice treated with CD226 overexpression iPSC-NK cells exhibited significantly reduced leukemia burden, prolonged survival, decreased systemic inflammation compared to those treated with Control iPSC-NK cells. Overall, our study provided evidence that iPSC derived-NK cells engineered with CD226 represent a promising candidate for off-the-shelf immunotherapy, particularly in AML and other CD226 ligand-expressing malignancies.

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 GSE292274_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 PRJNA1237813 and SRA study SRP571332. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 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.
