Tetramethylpyrazine potentiates arsenic trioxide activity against HL-60 cell lines

The objective of this study was to evaluate the effects of tetramethylpyrazine (TMP) in combination with arsenic trioxide (As2O3) on the proliferation and differentiation of HL-60 cells. The HL-60 cells were treated with 300 µg/mL TMP, 0.5 µM As2O3, and 300 µg/mL TMP combined with 0.5 µM As2O3, respectively. The proliferative inhibition rates were determined with MTT. Differentiation was detect...

Vitamin D3 potentiates the antitumorigenic effects of arsenic trioxide in human leukemia (HL-60) cells

BACKGROUND Arsenic trioxide (ATO) is a novel form of therapy that has been found to aid acute promyelocytic leukemia (APL) patients. Our laboratory has demonstrated that ATO-induced cytotoxicity in human leukemia (HL-60) cells is mediated by oxidative stress. Pro-oxidants have been known to play a role in free radical-mediated oxidative stress. Vitamin D3, (Vit D3) an active metabolite of vitam...

Vitamin D3 Potentiates the Antitumor Effects of Arsenic Trioxide in Human Leukemia (hl-60) Cells

Recent studies in our laboratory have indicated that oxidative stress plays a key role in ATOinduced cytotoxicity in human leukemia (HL-60) cells. Pro-oxidants have been known to plays a role in free radical-mediated oxidative stress. Medical reports have indicated that Vitamin D3, a well-known antioxidant works synergistically with tamoxifen to inhibit breast cancer cell proliferation. Therefo...

Docosahexaenoic acid enhances arsenic trioxide-mediated apoptosis in arsenic trioxide-resistant HL-60 cells.

Recent reports indicate a broad spectrum of antileukemic activity for arsenic trioxide (As(2)O(3)) due to its ability to induce apoptosis via intracellular production of reactive oxygen species (ROS). Despite its potent apoptotic mechanism, As(2)O(3) is not equally effective in all leukemic cells, which has prompted a search for agents enhancing As(2)O(3) efficacy. Recently, evidence has been g...

Arsenic Trioxide-induced Toxicity and Cell Death through Necrosis in Human Leukemia (hl-60) Cells

The treatment of acute promyelocytic leukemia (APL) has been based on the administration of all-trans retinoic acid plus anthracycline chemotherapy, which is very effective as first line therapy; however 25 to 30% of patients will relapse with their disease becoming refractory to conventional therapy. Therefore, the aim of the present study was to investigate whether arsenic trioxide (ATO) indu...
