Hypoxic Upregulation of IER2 Increases Paracrine GMFG Signaling of Endoplasmic Reticulum Stress‐CAF to Promote Chordoma Progression via Targeting ITGB1

et al.

Abstract: Currently, the oncogenic mechanism of endoplasmic reticulum stress‐CAF (ERS‐CAF) subpopulation in chordoma remains unknown. Here, single‐cell RNA sequencing, spatial transcriptomics, GeoMx Digital Spatial Profiler, data‐independent acquisition proteomics, bulk RNA‐seq, and multiplexed quantitative immunofluorescence are used to unveil the precise molecular mechanism of how ERS‐CAF affected chordoma progression. Results show that hypoxic microenvironment reprograms CAFs into ERS‐CAF subtype. Mechanistically, th… Show more
