Abstract

Quercetin and hyperoside (QH) in combination (1:1 ratio) have previously been shown to inhibit the growth of human leukemia cells. Here, we investigated the anticancer activity of the same mixture in 786-O renal cancer cells. QH decreased the generation of reactive oxygen species (ROS) by up to 2.25‑fold and increased the antioxidant capacity by up to 3-fold in 786-O cells (3.8-60 μg/ml), whereas IC50 values for viability were 18.2, 18.7 and 11.8 μg/ml, respectively. QH also induced caspase-3 cleavage (2-fold) and increased PARP cleavage. Specificity protein (Sp) transcription factors are overexpressed in cancer cells and regulate genes required for cell proliferation, survival and angiogenesis. QH treatment decreased the expression of Sp1, Sp3 and Sp4 mRNA and this was accompanied by decreased protein expression. Moreover, expression of the Sp-dependent anti-apoptotic survival gene survivin was also significantly reduced, both at the mRNA and protein levels. QH decreased microRNA‑27a (miR‑27a) and induced the zinc finger protein ZBTB10, an Sp-repressor, suggesting that interactions between QH and the miR‑27a‑ZBTB10 axis play a role in Sp downregulation. This was confirmed by transfection of cells with a specific mimic for miR‑27a, which partially reversed the effects of QH. These findings are consistent with previous studies on botanical anticancer agents in colon cancer cells.
