PRDM1 increases cell death in spinal disc core cells by activating CASP1, contributing to disc degeneration
Updated
Abstract
PRDM1 expression was substantially upregulated in degenerated nucleus pulposus tissues and cells.
- PRDM1 is linked to the regulation of cell death and inflammatory responses.
- Overexpression of PRDM1 promotes in nucleus pulposus cells, worsening intervertebral disc degeneration.
- Silencing PRDM1 reduces pyroptosis in these cells and may slow degeneration.
- PRDM1 activates the transcription of CASP1, contributing to the pyroptotic process.
- Inhibition of CASP1 can counteract the effects of PRDM1 on cell death.
