iFSP1

SKU: orb1219768

Description

iFSP1 is able to sensitize a variety of human cancer cell lines to the ferroptosis inducer, such as (1S,3R)-RSL3.iFSP1 is a potent, selective and glutathione-independent inhibitor of ferroptosis suppressor protein 1 (FSP1) (AIFM2) with an EC50 of 103 nM. iFSP1 selectively induces ferroptosis in GPX4-knockout cells which overexpressed FSP1.iFSP1 (0.001-1 μM; 24 hours) is less efficient than genetic deletion of FSP1, whereas iFSP1 treatment in the FSP1-knockout background had no additive effect to RSL3-induced ferroptosis.iFSP1 (3 μM; 24 hours) treatment results in an obvious toxicity of RSL3 in a panel of genetically engineered (FSP1-knockout) human cancer cell lines.AIFM2: the flavoprotein apoptosis-inducing factor mitochondria-associated 2 is a previously unrecognized anti-ferroptotic gene. AIFM2, which is renamed ferroptosis suppressor protein 1 (FSP1).iFSP1 (0.001-1 μM; 24 hours) inhibits the Gpx4-knockout cell growth as a dose-dependent manner, but does not inhibit the wild type cell growth. Treatment with the ferroptosis inhibitor Lip-1 protects GPX4- knockout cells from iFSP1-induced ferroptosis.

Cell Proliferation Assay Cell line: Wild-type and Gpx4-knockout Pfa1 or HT 1080 cells overexpressing FSP1-HA. Concentration: 0.001-1 μM Incubation time: 24 hours. Result: Was toxic to cells that depend solely (no GPX4 expression detectable) on FSP1 function. Cell Viability Assay Cell line: NCl-H1437, NCl-H1437 FSP1 KO, U-373, U-373 FSP1 KO, MDA-MB-436, MDA-MB-436 FSP1 KO, SW620, SW620 FSP1 KO, MDA-MB-435S, MDA-MB-435S FSP1 KO, A549 and A549 FSP1 KO. Concentration: 3 μM. Incubation time: 24 hours. Result: Sensitized a variety of human cancer cell lines to the ferroptosis inducer (1S, 3R)-RSL3.
