Increased expression of cyclic guanosine 3', 5' monophosphate phosphodiesterase-5 (cGMP-PDEs) mRNAs has been
demonstrated in several human carcinomas, including breast carcinoma, pancreatic cancer, bladder cancer, squamous
cell carcinoma and prostate cancer, in comparison to adjacent normal tissues. Studies have elucidated that an increase in
intracellular cGMP induces apoptosis and decreases cell population growth. Therefore, selective inhibitors of these PDEs
might be potential anticancer agents. Previous investigations have demonstrated that Levisticum officinale contains flavonoids
and alkaloids compound that are known as antitumoral components. The purpose of this study was to investigate the effect of
Levisticum officinale hydroalcoholic extract on phosphodiesterase 5 gene expression, cGMP signaling pathway and its role in
inducing apoptosis in the MCF-7(ER+) and in MDA-Mb-468 (triple-negative) cell lines. The mean inhibitory concentration
(IC50) of extract was determined in both cell lines using of MTT assay, and the type of cell death was detected by flow
cytometry. The expression of PDE5 and cGMP levels was measured by real-time polymerase chain reaction and colorimetric
assay, respectively. Treatment with hydroalchoholic extract of Levisticum officinale showed that 200 �?¼g/ml to be the IC50 for
both cell lines. 12 hour treatment with IC50 dosage showed a maximum decrease in the PDE5 expression and maximum
increase in intracellular cGMP level, although, these effects were more significant in MDA-MB-468. In conclusion, our results
showed that hydroalchoholic extract of Levisticum officinale had an anti-proliferative and apoptotic effect in MCF-7 and MDAMb-
468 targeting PDE5 and cGMP signaling pathway.
