NAMPT and NNMT released via extracellular vesicles and as soluble mediators are distinguished traits of BRAF inhibitor resistance of melanoma cells impacting on the tumor microenvironment

NAMPT and NNMT released via extracellular vesicles and as soluble mediators are distinguished traits of BRAF inhibitor resistance of melanoma cells impacting on the tumor microenvironment

Abstract Drugs targeting mutant BRAF and MEK oncogenes are effective in melanoma, even though resistance rapidly develops. This complex picture includes acquired intrinsic tumor and tumor microenvironmental-mediated mechanisms. Here we show that melanoma cells resistant to BRAF inhibitors (BRAFi) ov...
