AP-1 (c-FOS and c-JUN) eliminated the effects of PCI-34051 on HASMC ferroptosis. All HASMCs were infected with lenti-Flag and lenti-c-FOS + lenti-c-JUN, and then these HASMCs were used for subsequent experiments. (A, B) The protein level of AP-1 (c-JUN and c-FOS) was detected by Western blot in HASMCs infected with lenti-Flag and lenti-c-JUN + lenti-c-FOS ( n = 4 per group). (C, D) The CCK8 assay showing the relative viability of HASMCs treated with DMSO and PCI-34051 after CD (C) and IKE (D) stimulation for the indicated time ( n = 5 per group). (E, F) Flow cytometry with propidium iodide (PI) staining displaying the percentage of PI-positive cells of HASMCs after treatment as described above ( n = 4 per group). (G, H) The LDH assay indicating the relative cell damage rate of HASMCs treated with described above ( n = 5 per group). (I–L) The ratio of oxidized BODIPY-C11/non-oxidized BODIPY-C11 fluorescence revealing the level of ROS of HASMCs treated with described above ( n = 4 per group). (M–P). 4-HNE immunofluorescence staining and quantitative analysis exhibiting the content of 4-HNE in HASMCs after treatment as described above ( n = 4 per group). (Q–T) Western-blot analysis and quantification performed to assess the protein levels of GPX4, FSP1, and SLC7A11 in AP-1 overexpressed HASMCs after DMSO and PCI-34051 treatment along with CD or IKE induction. β-Actin served as a loading control ( n = 4 per group). Values are means ± SD; *** P < 0.001, ** P < 0.01, * P < 0.05.

The working model of PCI-34051 regulating HASMC ferroptosis and aortic dissection in mice. PCI-34051 inhibits the ferroptosis of HASMC by affecting the interaction between HDAC8 and AP-1 (c-FOS and c-JUN) and further suppresses the occurrence and development of BAPN-induced aortic dissection in mice. (This figure is created with Biorender).
