Selenomethionine alleviates T-2 toxin-induced articular chondrocyte ferroptosis via the system Xc−/GSH/GPX4 axis by Fang-fang Yu, Juan Zuo, Miao Wang, Shui-yuan Yu, Kang-ting Luo, Tong-tong Sha, Qian Li, Zai-chao Dong, Guo-yu Zhou, Feng Zhang, Xiong Guo, Yue Ba, Yan-jie Wang

“…Here, the oxidative stress and ferroptosis of chondrocytes exposure to T-2 toxin were observed. Mechanistically, T-2 toxin increased ROS, lipid ROS, MDA and Fe2+ contents in chondrocytes, decreased GSH and GPX4 activity, and inhibited the system Xc−/GSH/GPX4 antioxidant axis. …”

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). …”

KLF9-GRK5-HDAC6 axis aggravates osteoarthritis pathogenesis by promoting chondrocyte extracellular matrix degradation and apoptosis by Xiaonan Zhou, Peng Jiang, Huangqi Tan, Yanfang Wang, Lunhao Bai

“…KLF9 was upregulated in cartilage tissues of OA patients and medial meniscotibial ligament (MMTL)-induced OA rats, as well as in IL-1β-treated chondrocytes. Furthermore, knockdown of KLF9 inhibited OA-related cartilage injury, as evidenced by inhibiting chondrocyte extracellular matrix (ECM) degradation, increasing chondrocyte viability, and decreasing apoptosis. …”
