YAP1 regulates thrombopoiesis by binding to MYH9 in immune thrombocytopeniaBlood · 2024
Summary (written by the submitters)
Immune thrombocytopenia (ITP) is a complicated bleeding disease characterized by sharp platelet reduction. As a dominating element involved in ITP, megakaryocytes (MKs) are responsible for thrombopoiesis. However, the mechanism behind the dysregulation of thrombopoiesis in ITP remains undetermined. In this study, we examined the role of YAP1, Yes-associated protein 1, in thrombopoiesis during ITP.

We observed a reduced YAP1 expression with cytoskeletal actin misalignment in MKs of ITP patients. Using experimental ITP mice, we showed that YAP1 reduction induced aberrant MK distribution, reduced the percentage of late MKs in total MKs, and caused submaximal platelet recovery. Mechanistically, YAP1 upregulation by GATA1 binding to its promoter promoted MK maturation. Phosphorylated YAP1 facilitated cytoskeletal activation by binding of its WW2 domain to MYH9, facilitating thrombopoiesis. Targeting YAP1 by its activator XMU-MP-1 was sufficient to rescue cytoskeleton defects and thrombopoiesis in YAP1+/- ITP mice and ITP patients. Taken together, these results demonstrate a crucial role for YAP1 in thrombopoiesis, providing a potential for the development of diagnostic markers and therapeutic options for ITP.

This dataset
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 GSE250220_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 PRJNA1052693. Searching any of these in the dataset finder brings you back here.

Study design
7 × ITP vs 4 × Healthy control

Supports a between-group comparison across 11 samples.

How we read this: 2 replicated groups read from 11 sample titles; they account for 11 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.
