Eliminating Acute Myeloid Leukemia Stem Cells By Targeting The Niche Microenviromnent: Co-Inhibition Of Tnf/Il1- Jnk And Nf-Κb, Andrew Volk
Dissertations
Leukemia Stem Cells (LSCs) from Acute Myeloid Leukemia (AML) require the activity of the transcription factor NF-kB to maintain stemness and drive tumor formation. Blocking NF-kB can preferentially eliminate LSCs in vitro with minimal effects on healthy Hematopoietic Stem and Progenitor Cells (HSPCs), making NF-kB a compelling target for anti-leukemia therapies. However, blocking NF-kB in vivo can only extend survival for a short period of time before transplanted mice succumb to the disease. I propose this is due to components of the in vivo niche supporting LSC survival and compensating for the inhibition of NF-kB.
I observed patients with partially …
