Transforming growth factor beta (TGFβ) and activin A suppress natural killer (NK) cell function proliferation, limiting the efficacy of adoptive NK therapies. Inspired by partial resistance to TGFβ cells with SMAD4 haploinsufficiency, we used CRISPR–Cas9 for knockout in human cells. Here show that SMAD4KO were resistant inhibition, retaining their cytotoxicity, cytokine secretion interleukin-2/interleukin-15-driven proliferation. They showed enhanced tumor penetration control, both as...

Abstract In patients with trastuzumab-resistant HER2-positive breast cancer, the combination of everolimus (mTORC1 inhibitor) trastuzumab failed to show a clinically significant benefit. However, mTOR inhibition and antibody–drug conjugate (ADC) trastuzumab-emtansine (T-DM1) remains unexplored. We tested T-DM1 plus in broad panel cancer cell lines. The was superior alone four lines (HCC1954, SKBR3, EFM192A, MDA-MB-36) two cultures from primary tumor cells derived patient-derived xenografts...
