Summary (written by the submitters)
Enhancing ten-eleven translocation 2 (TET2) activity through genetic or pharmacologic approaches, such as ascorbate supplementation, can slow myeloid malignancy progression. However, ascorbate alone may be insufficient to fully activate TET2 in malignant cells due to pharmacokinetic constraints and the need for chromatin remodeling to enable effective cellular reprogramming.
Read the full summary ↓
Here, we identify a novel mechanism to enhance TET2 activity via all-trans retinoic acid (ATRA), which induces retinoic acid receptor alpha (RARA)-mediated TET2 transcription in myeloid leukemia cells and synergizes with ascorbate to promote DNA hydroxymethylation and chromatin remodeling at key myeloid differentiation loci. Using Tet1/2/3-deficient mice and primary human acute myeloid leukemia (AML) models, we show that ATRA plus ascorbate more effectively induces differentiation, inhibits leukemia stem cell self-renewal in a TET2-dependent manner, and sensitizes AML cells to targeted therapies in vivo, leading to improved survival. These findings support the combined use of ATRA and ascorbate as a strategy to enhance TET2 activity for the treatment of myeloid 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 GSE298861_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1271513 and SRA study SRP589632. Searching any of these in the dataset finder brings you back here.
