Abstract Title: 

Raspberry Extract With Potential Antitumor Activity Against Cervical Cancer.


BACKGROUND: Cervical cancer (CC) is one of the leading causes of mortality worldwide. Previously, we reported that blueberry extract constrains the growth of CC. Raspberry is a widely consumed fruit that exhibits antitumor properties against several cancer types but little is known about its direct effect on CC. This study was designed to investigate the potential antitumor effect of raspberry extract (RE) on CC cells and to elucidate the possible mechanisms behind it.MATERIALS AND METHODS: Clonogenic survival assay and caspase-3 activity kits were used to evaluate the effects of RE on cell survival, proliferation, and apoptosis of a widely used CC cell line, HeLa. Possible molecular mechanisms were investigated using reverse transcription-polymerase chain reaction.RESULTS: The percentage of colonies and optic density value of HeLa cells decreased in the presence of RE in comparison to controls. Relative caspase-3 activity in cancer cells increased in the presence of RE in comparison to controls. The antitumor effect displayed on HeLa cells by RE was associated with the increased expression of antiproliferative molecule P53 and the increased expression of pro-apoptotic molecule tumor necrosis factor receptor superfamily member 6 (FAS).CONCLUSION: RE displays anticancer activity against CC HeLa cells. The mechanism behind this is by up-regulation of anti-proliferative molecule P53 and pro-apoptotic molecule FAS.
