Tamoxifen Subcellular Localization; Observation of Cell-Specific Cytotoxicity Enhancement by Inhibition of Mitochondrial ETC Complexes I and III

Recently, a nongenomic cytotoxic component of the chemotherapeutic agent tamoxifen (TAM) has been identified that predominantly triggers mitochondrial events. The present study delineates the intracellular fate of TAM and studies its interaction with a spectrum of cell homeostasis modulators primarily relevant to mitochondria. The subcellular localization of TAM was assessed by confocal fluorescence microscopy. The effect of the modulators on TAM cytotoxicity was assessed by standard MTT assays. Our findings show that in estrogen receptor positive MCF7 breast adenocarcinoma cells and DU145 human prostate cancer cells, TAM largely accumulates in the mitochondria and endoplasmic reticulum, but not lysosomes. Our results further demonstrate that in MCF7, but not in DU145 cells, mitochondrial electron transport chain complex I and III inhibitors exacerbate TAM toxicity with an order of potency of myxothiazol = stigmatellin > rotenone > antimycin A, suggesting a cell-specific cytotoxic interplay between mitochondrial complex I and III function and TAM action.

Concepts for Contemporary Social Work: Globalization, Oppression, Social Exclusion, Human Rights, Etc.

The society wrestles with mass social change congruent with economic globalization and the communications revolution. This change creates new challenges for the social work profession in the areas of social and economic justice. This article analyzes the terminology of the new global era, words that signify a paradigm shift in outlook, most of them a reaction to the new authoritarianism of the age. Globalization, oppression, social exclusion, human rights, harm reduction, and restorative justice are the representative terms chosen.
