Experiment 1 Reporting the Ferroptosis Target of This Regulator [1]
Responsed Disease Oesophageal cancer ICD-11: 2B70
Pathway Response Fatty acid metabolism hsa01212
Ferroptosis hsa04216
Cell Process Cell ferroptosis
Cell proliferation
In Vitro Model
TE-1 cells Esophageal squamous cell carcinoma Homo sapiens CVCL_1759
KYSE30 cells Esophageal squamous cell carcinoma Homo sapiens CVCL_1351
In Vivo Model
A total of 128 immune active female C57BL/6 mice (6 weeks old) were procured from SLAC Laboratory Animal Co., Ltd. (Shanghai, China). ESCC cells (TE-1 and KYSE-30) resuspended in PBS were mixed with Matrigel and subcutaneously injected into the mice (1 x 106 cells per mouse) at the right flank to induce subcutaneous tumors. When the tumor size reached around 150 mm3, the tumor site was locally exposed to irradiation (2 Gy/d for consecutive 4 d). For antibody injection, the mice were injected with IgG or Anti-SIGECE on day 1, 7, or 14 after the first irradiation exposure. After 28 d, the mice were euthanized via overdosed barbiturate (150 mg/kg). The subcutaneous tumors were collected for IHC. Another group of ESCC cells were injected into mice via tail vein (2 x 106 cells per mouse).

Response regulation LINC01004 recruited Spi-1 proto-oncogene (SPI1) in nucleus of TAMs to induce transcriptional activation of SIGLEC9. SIGLEC9 interacted with mucin 1 (MUC1). MUC1 overexpression in esophageal squamous cell carcinoma (ESCC) induced M2 skewing of TAMs, enhanced radioresistance and immunosuppression, and promoted nuclear translocation of -catenin to suppress radiotherapy-induced ferroptosis of ESCC cells.
