Furthermore, in vitro and in vivo experiments validate the ability of the small molecule filgotinib, identified by D-FR20, to re-sensitize BBDI and effectively eliminate resistant TNBC cells. Collectively, this study provides two computational frameworks for predicting BBDI resistance and candidate re-sensitizer, as well as demonstrates the roles of ferroptosis in BBDI resistance, offering a promising avenue for TNBC treatment.
This mechanism of antigen loss can be rescued with anti-IFNγ neutralizing antibody, the JAK inhibitor ruxolitinib, or 4-phenylbutyrate (an ER stress reliever). We revealed a negative effect of IFNγ that uniquely interferes with immunotherapies targeting native surface antigens, such as CART and BiTE therapies, which may be reversed by disrupting stress signaling pathways to enhance solid tumor CART and BiTE immunotherapies.
In contrast, other JAK-STAT3 inhibitors such as ruxolitinib and knockdown of STAT3 does not replicate this effect, indicating that the anti-tumor effect of filgotinib is independent of JAK-STAT3 signaling. This study offers innovative insights and potential therapeutic strategies for the treatment of PDAC through EIF3A m6A.
