Role of the tumor microenvironment in mediating de novo resistance to drugs and physiological mediators of cell death

Hazlehurst, Lori A, Landowski, Terry H, Dalton, William S·2003·Oncogene

Abstract

The emergence of clinical drug resistance continues to be an obstacle for the successful treatment of cancer. Our current understanding of mechanisms associated with drug resistance has been ascertained by investigating drug-resistant models created by exposing a parental population to increasing concentrations of a cytotoxic. These unicellular drug-resistant models have been critical in elucidating drug-resistant mechanism and in some cases have aided in the identification of drug targets. However, these models do not address resistance mechanisms that contribute to de novo drug resistance. We propose that specific niches within the tumor microenvironment may provide a sanctuary for subpopulations of tumors cells that affords a survival advantage following initial drug exposure and may facilitate the acquisition of acquired drug resistance. More specifically, we propose that the bone marrow microenvironment is a sanctuary for hema-topoietic cancers. This review will focus on the bone marrow microenvironment and its role in conferring resistance to cytotoxics and physiological mediators of cell death.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
