Kaempferol Attenuates Spaceflight-Associated Knee Cartilage Degradation by Targeting NOX4-Mediated Mitochondrial DysfunctionAdvanced science (Weinheim, Baden-Wurttemberg, Germany) · 2026
Summary (written by the submitters)
Microgravity and space radiation experienced during spaceflight have negative effects on musculoskeletal health, yet their impact on articular cartilage remains poorly understood. In this study, we demonstrated that simulated spaceflight on Earth leads to cartilage degeneration in the knees of mice. Similar changes were also observed in mice exposed to actual space flight.

To investigate the mechanisms behind spaceflight-associated cartilage loss, human chondrocytes were encapsulated within a hydrogel scaffold and then subjected to rotary culture to mimic the alterations caused by microgravity. Simulated microgravity increased the expression of biomarkers related to inflammation and cellular senescence. Additionally, rotary culture decreased mitochondrial respiration and increased the production of reactive oxygen species. Through RNA sequencing and bioenergetic profiling, we identified NADPH oxidase 4 (NOX4) as a crucial factor driving these changes. Additionally, kaempferol, a naturally occurring flavonoid that directly binds to NOX4, was found to partially reverse the harmful effects of microgravity on chondrocytes. Finally, systemic administration of kaempferol reduced cartilage degradation in mice subjected to simulated spaceflight on the ground. These findings establish that NOX4-mediated mitochondrial dysfunction is a key mechanism underlying spaceflight-induced cartilage degeneration and highlight kaempferol as a potential protective measure for joint health in space.

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 GSE310264_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 PRJNA1365659 and SRA study SRP646175. Searching any of these in the dataset finder brings you back here.
