Experiment 1 Reporting the Ferroptosis Target of This Regulator [1]
Responsed Disease Acute pancreatitis ICD-11: DC31
 Disease Info 
Pathway Response Fatty acid metabolism hsa01212
Autophagy hsa04140
Cell Process Cell ferroptosis
Cell autophagy
In Vitro Model
 HT-1080 cells Fibrosarcoma Homo sapiens CVCL_0317
Calu-1 cells Lung squamous cell carcinoma Homo sapiens CVCL_0608
PANC-1 cells Pancreatic ductal adenocarcinoma Homo sapiens CVCL_0480
5637 cells Bladder carcinoma Homo sapiens CVCL_0126
SK-OV-3 cells Ovarian serous cystadenocarcinoma Homo sapiens CVCL_0532
PC-3 cells Prostate carcinoma Homo sapiens CVCL_0035
In Vivo Model
Pancreatic-specific gpx4 knockout mice were produced and identified in our laboratory by crossing floxed Gpx4 (a gift from Dr. Qitao Ran, UT Health San Antonio) and Pdx1-Cre (the Jackson Laboratory, 014647) transgenic mice (C57BL/6J background). For cerulein-induced acute pancreatitis, female mice (8-10 weeks) received seven hourly i.p. injections of 50 ug/kg cerulein in sterile saline. We repeatedly administered iHPCAL1 by i.p. at a dose of 10 mg/kg to mice at 3 and 12 h after the first cerulein injection, while controls were treated by administration with vehicle. The parameters of acute pancreatitis were assessed 12 h after the last cerulein treatment.

Response regulation HPCAL1 as a specific autophagy receptor provides the first mechanistic understanding of how CDH2 is selectively delivered to phagophores, leading to CDH2 degradation for the induction of ferroptosis. The genetic or pharmacological inhibition of HPCAL1 prevented ferroptosis-induced tumor suppression and pancreatitis in suitable mouse models.
