Chemotherapy-resistant human acute myeloid leukemia cells are not enriched for leukemic stem cells but require oxidative metabolism
Chemotherapy-resistant human acute myeloid leukemia (AML) cells are thought to be enriched
in quiescent immature leukemic stem cells (LSC). To validate this hypothesis in vivo, we …

Signatures of microRNAs and selected microRNA target genes in human melanoma
Small noncoding microRNAs (miRNA) regulate the expression of target mRNAs by repressing
their translation or orchestrating their sequence-specific degradation. In this study, we …

Neurodegeneration by activation of the microglial complement–phagosome pathway
Systemic inflammatory reactions have been postulated to exacerbate neurodegenerative
diseases via microglial activation. We now demonstrate in vivo that repeated systemic …
