P4HA3 drives cervical cancer lymphatic metastasis by facilitating ACLY-mediated ferroptosis resistanceCell death and differentiation · 2026
Summary (written by the submitters)
The lymph node is the most common site of distant metastasis of cervical cancer (CCa), which elicits dismal prognosis and limited efficiency for treatment. Identification of the factors contributing to CCa lymphatic metastasis is needed to develop effective prevention and treatment strategies. Here, we found upregulation of prolyl 4-hydroxylase subunit alpha 3 (P4HA3), an α-subunit of prolyl hydroxylase, in lymphatic metastatic lesions of cervical cancer, which is strongly associated with poor prognosis.

In vitro and in vivo experiments showed that P4HA3 promoted CCa lymphatic metastasis by conferring ATP-citrate lyase (ACLY)-mediated ferroptosis resistance. Mechanistically, P4HA3 stabilizes ACLY protein by competitively inhibiting its interaction with the E3 ubiquitin ligase UBR4, which prevents UBR4-mediated proteasomal degradation of ACLY. ACLY-derived acetyl-CoA enhances H3K27 acetylation (H3K27Ac) modification level in the promoter of SLC7A11 gene, ultimately enhancing SLC7A11 transcription and ferroptosis resistance. Collectively, our study provides a mechanistic understanding of the interplay between ferroptosis resistance and lymph node metastasis, providing a possibility to combat lymph node metastasis in cervical cancer.

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 GSE308704_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 PRJNA1332558 and SRA study SRP624275. Searching any of these in the dataset finder brings you back here.
