Paper
Differentiating erythroblasts adapt to mechanical stimulation by upregulation of cholesterol biosynthesis via S1P/SREBP-induced HMGCR expressionScientific reports · 2024
Summary (written by the submitters)
In vitro culture of erythroblasts and production of mature erythrocytes for transfusion purposes requires upscaling in bioreactors with turbulent fluidic environments, resulting in membrane shear stress. For the implementation of erythroid cultures in bioreactors, further understanding of the effects of mechanical stress on terminal erythroblast differentiation are required.

To this end, we investigated the effect of orbital shaking-induced shear stress on differentiation of CD49d+CD235low primary human erythroblast (EBL) towards enucleated reticulocytes at the molecular, cellular, and functional level. Orbital shaking at the onset of erythroblast differentiation enhanced cell maturation and increased enucleation percentage compared to static cultures, without loss of cell viability. Transcriptome analysis uncovered 505 genes to be differentially expressed between static and non-static cultures, where genes involved in lipids and cholesterol biosynthesis pathways where upregulated in non-static conditions. In line with this finding, cells differentiated in orbital shakers showed an increased cholesterol concentration and higher osmotic resistance compared to cells differentiated in static condition. HMGCR (3-Hydroxy-3-Methylglutaryl-CoA-Reductase), a rate limiting enzyme of the cholesterol biosynthesis pathway, is significantly increased and showed earlier induction during differentiation in shear stress environments. Inhibition of HMGCR using lovastatin led to severe loss of EBL differentiation in shear environments but not in static conditions. In conclusion, differentiating EBL display a dynamic capability to adapt to shear stress environments, by modulating their transcriptional program and consequently upregulating cholesterol biosynthesis, which is critical for their survival. This work sheds light into specific mechanisms which will assist on the successful upscaling of erythroid differentiation in turbulent bioreactors.

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 GSE247121_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 PRJNA1036247 and SRA study SRP470394. Searching any of these in the dataset finder brings you back here.
