Red grape seed extract and its compound resveratrol exert cytotoxic effect to various human cancer lines
Abstract:
Modern medicinal agents currently available for treatment of cancers are very expensive, toxic, and less effective in treating some of the disease. Thus, one must investigate further in detail the agents derived from natural sources, such as grape seed, for the prevention and treatment of cancer and disease. In recent years interest of researchers has focused on grape seed and nowadays scientists have used extracts of grape seed to treat different health problems including cancer. We examined the cytotoxic effect of red grape seed extract (GSE) and its main compound resveratrol (RES) on different human cancer cell lines representing various solid tumors and hematological malignancies at the same time. Red GSE was prepared by using 1, 1, 1, 2- Tetrafluoroethane extraction method. Cytotoxicity of the extract and RES was evaluated by using trypan blue dye exclusion method and MTT assay. The results of our study show that GSE and RES have cytotoxic activities in varying degree in several cancer cell lines. There has not been any study evaluating the GES and RES in the same cell lines and in the same conditions. But, it is still needed to have more pre-clinical and laboratory studies to validate the usefulness of these agents either alone or in combination with existing therapy.
Insights
Red grape seed extract (GSE) and resveratrol (RES) show cytotoxic effects against various human cancer cell lines. Further research is needed to confirm their potential as cancer treatments.
Area of Science:
- Oncology
- Natural Product Chemistry
- Pharmacology
Background:
- Current cancer therapies are often expensive, toxic, and have limited efficacy.
- Natural sources, like grape seeds, offer potential alternatives for cancer prevention and treatment.
- Grape seed extract (GSE) and its compound resveratrol (RES) have garnered research interest for health benefits, including anti-cancer properties.
Purpose of the Study:
- To evaluate the cytotoxic effects of red grape seed extract (GSE) and resveratrol (RES) on diverse human cancer cell lines.
- To compare the efficacy of GSE and RES under identical experimental conditions.
- To investigate the potential of natural compounds as adjuncts or alternatives in cancer therapy.
Main Methods:
- Red grape seed extract (GSE) was prepared using 1,1,1,2-Tetrafluoroethane extraction.
- Cytotoxicity was assessed using the trypan blue dye exclusion method and MTT assay.
- The study included various human cancer cell lines representing solid tumors and hematological malignancies.
Main Results:
- Both GSE and RES demonstrated cytotoxic activities against the tested cancer cell lines.
- The degree of cytotoxicity varied among different cancer cell lines.
- This study is the first to evaluate both GSE and RES simultaneously in the same cell lines and conditions.
Conclusions:
- Red grape seed extract and resveratrol exhibit cytotoxic potential against a range of human cancer cells.
- These natural agents warrant further investigation for their therapeutic applications in oncology.
- Additional pre-clinical and laboratory studies are essential to validate their use, alone or in combination with existing therapies.
