Gene Silencing of ANGPTL3 Induces PCSK9: Exploring the Biological Significance in the Hepatoma Huh7 Cell LineCells · 2026
Summary (written by the submitters)
Background: Angiopoietin-like 3 (ANGPTL3) is a hepatokine acting as negative regulator of hepatic and endothelial lipases. Vupanorsen, an antisense oligonucleotide targeting ANGPTL3, reduced triglycerides up to 60% in a phase 2b trial, but caused dose-dependent increases in hepatic fat fraction. Proprotein convertase subtilisin/kexin type 9 (PCSK9) plasma levels also correlates with liver fat accumulation.

Methods: To further elucidate the biological activity of ANGPTL3 on lipid metabolism in the liver we performed a RNAseq analysis from human hepatoma Huh7 cells transfected with siRNA-ANGPTL3, siRNA-PCSK9 and double siRNA-ANGPTL3/PCSK9. Results: RNA-seq analysis detected 192 genes out of 13,945 transcripts differential ex-pressed in response to ANGPTL3-siRNA compared to scramble-siRNA controls. In cells transfected with PCSK9-siRNA, 88 genes were differentially expressed, while dual transfection with both ANGPTL3- and PCSK9-siRNA resulted in 219 differentially ex-pressed genes. When ANGPTL3 gene expression was silenced we observed a compensa-tory induction of proprotein convertase subtilisin/kexin type 9 (PCSK9) mRNA and pro-tein expression. Moreover, PCSK9 silencing increased ANGPTL3 mRNA expression. Bi-oinformatic analysis revealed that gene silencing of ANGPTL3 or both ANGPTL3/PCSK9 suppresses SERPINA1, gene encoding α1-antitrypsin, and lectin mannose-binding 1 ex-pression (LMAN1). These data were confirmed by western blot and qRT-PCR analysis. Conclusions: Our data identified two key genes SERPINA1 and LMAN1, involved in endoplasmic reticulum stress, lipid accumulation and liver damage, that are downregu-lated in response to gene silencing of ANGPTL3 in Huh7 hepatoma cell line.

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 GSE312289_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 PRJNA1372774 and SRA study SRP650845. Searching any of these in the dataset finder brings you back here.

Study design
3 × CTRL vs 3 × Ang3 vs 3 × PCSK9 vs 3 × A3P9

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.
