Fibroblast growth factor receptor 3 mutation promotes HSPB6-mediated cuproptosis in hypochondroplasia by impairing chondrocyte autophagy by Jing Chen, Dan He, Chengrun Yuan, Na Li, Baohong Shi, Conway Niu, Jiangfei Yang, Liangkai Zheng, Lin Che, Ren Xu

“…We demonstrated that the mutant-activated FGFR3 promotes heat shock protein B 6 (HSPB6)-mediated cuproptosis by inhibiting chondrocyte autophagy both in vivo and in vitro. Additionally, we revealed that FGFR3 (G382D) mutation leads to enhanced ERK signaling, increased Drp1-mediated mitochondrial fission, and upregulated cuproptosis-related protein ferredoxin 1 (FDX1). …”
