Silencing KRIT1 Partially Reverses the Effects of Disturbed Flow on the Endothelial Cell TranscriptomeInternational journal of molecular sciences · 2025
Summary (written by the submitters)
Endothelial cells respond to forces generated by laminar blood flow with changes in vasodilation, anticoagulant, fibrinolytic, or anti-inflammatory functions which preserve vessel patency. These responses to flow are primarily mediated by the elevation of transcription factors Krüppel-like factors 2 and 4 (KLF2 and KLF4). Notably, turbulent flow patterns, which predispose to atherosclerosis, significantly reduce the endothelial expression of KLF2 and KLF4 and reulting changes in the transcriptome that exacerbate inflammation and thrombosis.

The CCM complex, comprising KRIT1, CCM2, and CCM3 suppress expression of KLF2 and KLF4. Loss of function of the CCM complex has recently been suggested to protect from coronary atherosclerosis in humans. We thus hypothesized that silencing of KRIT1, the central scaffold of the CCM complex, can normalize the effects of turbulent flow on the human endothelial transcriptome. We conducted bulk RNA sequencing (RNA-seq) on human umbilical vein endothelial cells (HUVECs) after silencing KRIT1 expression using specific siRNAs. The endothelial cells were exposed to pulsatile shear stress (laminar flow), oscillatory shear stress (disturbed flow), or no flow for 24 hours.

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 GSE288811_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 PRJNA1219536 and SRA study SRP561731. Searching any of these in the dataset finder brings you back here.
