Dual Targeting of Matrix Metalloproteases and the MAPK Pathway in Acute Myeloid Leukemia Cells Using an MMP-activated anthrax lethal toxin (PrAgL1/LF)
Published 2020“…Inhibition of the MAPK pathway through PrAgL1/LF led to sustained activation of autophagy, starting at 24 hours and lasting up to 120 hours following treatment with PrAgL1/LF in the AML cell lines. Addition of CQ led to an increase in cell cytotoxicity following treatment with PrAgL1/LF, at all time points, indicating that the inhibition of the MAPK pathway in AML cells leads to the activation of autophagy, which in turn mediates cell death following treatment with PrAgL1/LF. …”
