GPX4-AUTAC is a GPX4-targeting autophagy-mediated degrader (AUTAC). GPX4-AUTAC consists of an inhibitor ML162-yne (HY-153748), a degradation tag FBnG (HY-W073762) and a glycol linker (HY-W021401). GPX4-AUTAC promotes the ubiquitination of GPX4 by E3 ligase TRAF6, and enhances the binding with GPX4 and p62, leading to the selective autophagy-dependent degradation of GPX4. GPX4-AUTAC significantly induces ferroptosis and shows a potent anti-cancer activity in breast cancer cells, breast cancer-derived organoids (PDOs) and MDA-MB-231 tumor xenograft mice model, with potent synergistic effects when combined with Sulfasalazine (SAS) (HY-14655) or chemotherapy drugs (Paclitaxel (HY-B0015) or Cisplatin (HY-17394)).

In Vitro

GPX4-AUTAC (5-80 μM, 12-72 h) significantly reduces the protein level of GPX4 in a dose- and time-dependent manner, but barely affects the mRNA level of GPX4 in MDA-MB-231 and MCF-7 cells ^[1].
GPX4-AUTAC (20-40 μM, 24 h) effectively reduces the protein level of GPX4 in ovarian cancer, lung cancer, melanoma, and glioma cells^[1].
GPX4-AUTAC (10 μM, 24-96 h, 37-57°C) continuously down-regulates GPX4 protein level for 96 h and significantly enhances the thermal stability of GPX4 in heat-denatured intact cells and cell lysates in MDA-MB-231 and MCF-7 cells^[1].
GPX4-AUTAC (5-80 μM, 24 h) selectively degrades GPX4 without influence other selenoproteins expression, such as of GPX1, TXNRD1 (GPX4 homologs) or HK2 (a TRAF6/p62 substrate)^[1].
GPX4-AUTAC selectively degrades GPX4 and induces ferroptosis in tumor cells (MDA-MB-231 cells) with minimal effect on normal cells (MCF-10A cells)^[1].
GPX4-AUTAC (10 μM, 24 h) autophagy-dependently accelerates GPX4 degradation, increases polyubiquitylation of GPX4, specifically the endogenous and exogenous K63-linked ubiquitin chains in HEK293T cells^[1].
GPX4-AUTAC (10-40 μM, 12 h) is reversed by PYR-41, NH4Cl and 3-MA to reduce the down-regulation of GPX4 in MDA-MB-231 cells^[1].
GPX4-AUTAC (24 h) induces co-localization of GPX4 and p62 and increases co-localization of GPX4 with LC3B or LAMP2 in PDOs^[1].
GPX4-AUTAC (40?μM, 24?h) selectively targets GPX4 and ferroptosis is significantly enriched in MDA-MB-231 cells^[1].
GPX4-AUTAC (5-40 μM, 72 h) has a specific ferroptosis inductive effect, and significantly enhanced the lipid ROS and promoted accumulation of Fe²⁺ in MDA-MB-231 cells, but only fully rescued by the ferroptosis inhibitor Ferrostatin-1 (Fer-1) (HY-100579) in MCF-7 cells^[1].
GPX4-AUTAC (5-80 μM) induces ferroptosis with mitochondrial dysfunction (abnormal morphology, dense content and disrupted crista) and significant increase in mRNA levels of PTGS2 in MDA-MB-231^[1].
GPX4-AUTAC (5-40 μM, 24-96 h) dose- and time-dependently inhibited cell viability and proliferation, with insensitivity to knock-down of GPX4 in both MDA-MB-231 and MCF-7 cells^[1].
GPX4-AUTAC (5-40 μM, 4 days) significantly inhibits the growth of PDOs with reducing diameter and bright-field, and PDOs with high expression of GPX4 increases sensitivity ^[1].
GPX4-AUTAC (10-20 μM, 4 days) down-regulates GPX4 expression and induces ferroptosis with high level of 4-HNE, and inhibits cancer cell proliferation in PDOs with low level of Ki67^[1].
GPX4-AUTAC induces much more ferroptosis and has a stronger anti-cancer effect in combination with Sulfasalazine compared to Sulfasalazine alone treatment in MDA-MB-231 and MCF-7 cells and PDOs ^[1].
GPX4-AUTAC (10?μM, 72 h or 4 days) sensitizes MDA-MB-231 and HCC1806 cells to chemotherapy and synergistically inhibits cell viability and proliferation and the growth of PDOs in combination with chemotherapy drugs (Paclitaxel or Cisplatin)^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
