Özet

Pyrethrum extract (PE), an important natural bioinsecticide, is extensively used across the world to control pest insects in homes and farms. The aim of this study was to evaluate the potential cytotoxic effect of PE using MTT assay and genotoxic effect using micronucleus (MN) assay. The changes in the expressions of the apoptosis genes in mRNA levels were also investigated using Real-Time qPCR analysis as well as the ratio of apoptotic/necrotic cells with AnnexinV-FITC/Propidium iodide (PI) assay in HepG2 cells. PE markedly suppressed the cell proliferation on HepG2 cells. It significantly increased the frequency of micronucleus (MN) at 500 and 1000 mu g/mL. PE also induced the percentage of the cell population of late apoptotic/necrotic cells (FITC + PI+) and necrotic cells (FITC- PI+), especially at 4000 mu g/mL analyzed by flow cytometry. PE caused significant fold changes in the expression of several apoptotic genes including APAF1, BIK, BAX, BAD, BID, MCL-1, CASP3, CASP1, CASP2, FAS, FADD and TNFRSF1A. In particular, the pro-apoptotic gene Hrk (Harakiri) remarkably and dose-dependently was overexpressed of the mRNA level. As a result, PE may exhibit cyto-genotoxic effects, especially at higher concentrations and lead to significant changes in the expression of mRNA levels in several apoptotic genes.
