Identification of important genes related to ferroptosis in early missed abortion based on WGCNAScientific reports · 2025
Summary (written by the submitters)
A large proportion of miscarriages are classified as unexplained miscarriages (UM) since no cause is identified. No reliable biomarkers or treatments are available for these pregnancy losses. While our transcriptomic sequencing has revealed substantial upregulation of miR-146b-5p in UM villous tissues, its role and associated molecular processes have yet to be fully characterized.

Our work revealed that relative to samples from normal pregnancy (NP), miR-146b-5p was significantly elevated in villous tissues from UM patients and displayed promising diagnostic potential. Moreover, miR-146b-5p agomir contributed to higher rates of embryonic resorption in ICR mice. When overexpressed in HTR-8/SVneo cells, miR-146b-5p attenuated the proliferative, invasive, and migratory activity of these cells while suppressing the expression of MMP9 and immune inflammation-associated cytokines, including IL1B, IL11, CXCL1, CXCL8, and CXCL12. Conversely, inhibition of its expression enhanced proliferation, migration, and invasion abilities. Mechanistically, IRAK1 (IL-1 receptor-associated kinase-1) and ADAM19 (a disintegrin and metalloproteinase 19) were identified as miR-146b-5p targets regulating trophoblast function, and silencing IRAK1 had similar effects as miR-146b-5p overexpression, while IRAK1 overexpression could partially reverse the inhibitory impact of this miRNA on trophoblasts. miR-146b-5p may inhibit trophoblast proliferation, migration, invasion, and implantation-associated inflammation by downregulating IRAK1 and ADAM19, participating in the pathogenesis of miscarriage and providing a critical biomarker and a promising therapeutic target for UM.

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 GSE237732_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.

Also filed as BioProject PRJNA996514 and SRA study SRP450371. Searching any of these in the dataset finder brings you back here.

Study design
5 × normal pregnancy

Supports a between-group comparison across 5 samples.

How we read this: 1 replicated groups read from 10 sample titles; they account for 5 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.
