Fig. 1From: Effects of the aqueous extract of a Tibetan herb, Rhodiola algida var. tangutica on proliferation and HIF-1α, HIF-2α expression in MCF-7 cells under hypoxic condition in vitroEffect of Rhodiola algida var. tangutica on the viability of MCF-7 cell. MCF-7 cell were cultured in microwells and incubated with increasing concentrations of Rhodiola algida var. tangutica 0, 6, 12, 24, 48 and 72 h after incubation with different concentrations of Rhodiola algida var. tangutica, percentage viability of MCF-7 cell was determined by trypan blue exclusion. The highest concentration (450 μg/mL) of Rhodiola algida var. tangutica caused a significant decrease in cell viability compared with control.Back to article page
