Abstract
|
|
|
The flowers and leaves buds of Buddleja officinalis are used to treat eye troubles, hernia, gonorrhea and liver troubles in Asia. The present study investigated the effect of aqueous extract of Buddleja officinalis (ABO) on indoxyl sulfate (IS)-induced inhibition of cell proliferation in HK-2 cells. The HK-2 cells were incubated with 5 mM IS 5 mM in the absence or presence of ABO (2, 5, 10, 20 ¥ìg/ml) for 24 hr. The effect of ABO on IS-treated HK-2 cells was investigated by using MTT assay, flow cytometric analysis and Western blot. IS-induced proliferation inhibition was recovered dose-dependently by treatment with ABO. ABO reduced S and G2/M phase cell cycle arrest induced by IS. Recovery effect of ABO on inhibition of cell proliferation by IS is related to the decrease of p21 expression. Taken together, these results suggest that recovery effect of ABO on proliferation of IS-treated HK-2 cells be associated with cell cycle progression through down-regulation of p21 levels.
