We utilized gene targeting by homologous recombination to define the role that MEF, a transcriptional activating member of the ETS family of transcription factors, plays in lymphopoiesis. MEF-/- mice have a profound reduction in the number of NK-T and NK cells. Purified MEF-/- NK cells cannot lyse tumor cell targets and secrete only minimal amounts of(More)
The LIM domain protein rhombotin-2 (RBTN-2/TTG-2/Lmo2) has distinct functions in erythropoiesis and in T-cell leukemogenesis. Additional functions for RBTN2 are indicated by its expression in non-hematopoietic tissues. These diverse functions of RBTN2 are presumed to be accomplished through physical interaction with different protein partners that bind the(More)
MEF is an ETS-related transcription factor with strong transcriptional activating activity that affects hematopoietic stem cell behavior and is required for normal NK cell and NK T-cell development. The MEF (also known as ELF4) gene is repressed by several leukemia-associated fusion transcription factor proteins (PML-retinoic acid receptor alpha and(More)
Overcoming acquired drug resistance remains a core challenge in the clinical management of human cancer, including in urothelial carcinoma of the bladder (UCB). Cancer stem-like cells (CSC) have been implicated in the emergence of drug resistance but mechanisms and intervention points are not completely understood. Here we report that the pro-inflammatory(More)
