-2 overexpression, by means of the modulation in the redox atmosphere. The inability of Bcl-2 to sustain redox homeostasis, in response to increased oxidative strain, may be attributed to ATN-224’s capability to target CcOX [11]. Disrupting the ability of Bcl-2 to maintain mitochondrial respiration, by way of the regulation of CcOX activity, appears to have possible as a novel therapuetic stragety for circumventing Bcl-2 overexpression. Our data suggest that ATN-224 has pontential as an adjuvant in combination with ROSimplicated chemotherapeutics. There are numerous ROS-implicated chemotherapeutics employed to treat lymphoid malignancies, like bortezomib, gluocorticoids and aresenic trioxide [20, 47, 48]. Enhancing the efficacy of these drugs will be of great benefit for the patient, in particular when reduced doses could possibly be utilized. Within the case of doxorubicin, where cardiotoxicity is really a dose limiting aspect [49], decreasing the dose when attaining comparable if not superior efficacy could boost patient outcome. In ovarian cancer Kim et al. showed that another analogue of tetrathiomolybdate enhanced the impact of mitomycin C, fenretinide and 5fluorouracil [50], suggesting ATN-224 also has potential as an drug adjuvant in strong tumors. Redox modulating drugs mainly attain efficacy in combination with other chemotherapeutics. In our model, ATN-224 was capable to induce cell death at nanomolarNIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptFree Radic Biol Med.

Hematological malignancies arise at sites of chronic inflammation, therefore exposing them to larger levels of oxidative tension [2]. In response to enhanced oxidative anxiety, cells upregulate antioxidant defense enzymes [3], suggesting these malignanices could exhibit chemoresistance. Lots of hematological malignancies overexpress Bcl-2, which is connected with drug resistance. The capability of ATN-224 to induce cell death straight or act as a chemosensitizer in tumor cells with known chemoresistance mechanisms indicates that ATN-224 has clinical prospective for the therapy of hematological malignancies.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptAcknowledgmentsWe thank John Fitch and Paula Campbell at the AZCC Cytometry Core Facility for their assistance plus the Arizona Lymphoid Tissue and Blood Repository that is supported by 1P50CA130805-04.916304-19-3 Price This function was supported by National Cancer Institute Grants CA09213 (KL) and CA71768 (MMB).PMID:23381601 APM was supported by U01 CA151461-02, P50 HL107186-01 and H Foundation Funds.
