Experiment 1 Reporting the Ferroptosis Target of This Regulator [1]
Target for Ferroptosis Suppressor
Responsed Disease Ovarian cancer ICD-11: 2C73
 Disease Info 
Pathway Response Fatty acid metabolism hsa01212
Cell Process Cell ferroptosis
Cell apoptosis
In Vitro Model
 HEY cells Ovarian carcinoma Homo sapiens CVCL_0297
A2780 cells Ovarian endometrioid adenocarcinoma Homo sapiens CVCL_0134
SK-OV-3 cells Ovarian serous cystadenocarcinoma Homo sapiens CVCL_0532
HEK-293T cells Normal Homo sapiens CVCL_0063
In Vivo Model
Female 4- to 6-week-old BALB/c nude mice were purchased from SLA Laboratory Animal (Changsha, China) and housed in a specific pathogen-free facility. 2 x 106 A2780 or 1 x 106 HEY cells were injected subcutaneously into mice to grow tumors up to approximately 100 mm3. Mice were then intraperitoneally injected olaparib (100 mg/kg) or/and liproxstatin-1 (10 mg/kg, A2780) or/and sulfasalazine (250 mg/kg, HEY) until the endpoint indicated in the corresponding figures.

Response regulation Mechanistically, pharmacological inhibition or genetic deletion of PARP4 downregulates the expression of cystine transporter SLC7A11 in a p53-dependent manner. Consequently, decreased glutathione biosynthesis caused by SLC7A11 repression promotes lipid peroxidation and ferroptosis. Pharmacologic inhibition of PARP4 is the primary therapeutic strategy for BRCA mutant ovarian cancer.
