Gemcitabine-based chemotherapy regimens have shown limited antitumor effects for PDAC, and combination targets are urgently needed to restrict chemoresistance. Mechanistically, the focal adhesion kinase (FAK) inhibitor (IN10018) could restrict chemoresistance to Gem of PDAC by targeting SLC7A11-mediated ferroptosis through PI3K-Akt signaling pathway. For tumor microenvironment, IN10018 reduced the abundance of mesenchymal components and enhanced CD8+ T cell infiltration.

These models were treated with FAK inhibitor IN10018 as monotherapy or in combination with anti-PD-1 immunotherapy...FAK inhibitors can enhance the sensitivity of HCC to anti-PD-1 therapy by inhibiting angiogenesis and fibrosis and promoting CD8+ T cell infiltration. This effect exceeds the efficacy of the current first-line treatment, highlighting FAK inhibition as a novel and promising therapeutic strategy for HCC.
By inhibiting FAK activation and upregulating PIK3IP1, Ifebemtinib and paclitaxel blocked the PI3K/Akt pathway, effectively suppressing TNBC proliferation and metastasis. Our findings suggest that FAK may serve as a potential therapeutic target for TNBC.

We show that focal adhesion kinase (FAK) inhibition with ifebemtinib or tumor genetic FAK knockout (KO) in syngeneic ovarian tumor models stimulated resident large peritoneal macrophages to express CXCL13 chemokine and promoted B cell infiltration. reveal that tumor FAK inhibition educates macrophages to express CXCL13 associated with B cell infiltration - highlighting a new therapeutic pathway linking FAK inhibition, omega-3 fatty acid containing exosomes, and macrophage mediated anti-tumor activation. Genetic or small molecule FAK inhibition enhances ovarian tumor B cell infiltrationTumor FAK inhibition stimulates GATA6+ macrophages to make CXCL13FAKi, pegylated doxorubicin and anti-TIGIT promote tertiary lymphoid structuresOmega-3 fatty acids stimulate human HGSOC ascites macrophages to make CXCL13.
