abstract = {Chronic lymphocytic leukemia is a malignancy of mature B
cells that strongly depend on microenvironmental factors,
and their deprivation has been identified as a promising
treatment approach for this incurable disease. Cytokine
array screening of 247 chronic lymphocytic leukemia serum
samples revealed elevated levels of tumor necrosis factor
(TNF) receptor-1 which were associated with poor clinical
outcome. We detected a microenvironment-induced expression
of TNF receptor-1 in chronic lymphocytic leukemia cells in
vitro, and an aberrantly high expression of this receptor in
the proliferation centers of patients' lymph nodes.
Stimulation of TNF receptor-1 with TNF-α enhanced nuclear
factor κ-light-chain-enhancer of activated B cells (NFκB)
activity and viability of chronic lymphocytic leukemia
cells, which was inhibited by wogonin. The therapeutic
effects of wogonin were analyzed in mice after adoptive
transfer of Eμ-T-cell leukemia 1 (TCL1) leukemic cells.
Wogonin treatment prevented leukemia development when given
early after transplantation. The treatment of full-blown
leukemia resulted in the loss of the TNF receptor-1 on
chronic lymphocytic leukemia cells and their mobilization to
blood. Targeting TNF receptor-1 signaling is therefore
proposed for the treatment of chronic lymphocytic leukemia.},
