Abstract

Background: Glucose is associated with weight gain, which increases the risk of cancer. There is insufficient information on the effects of high glucose concentrations on cell lines. This study evaluated the viability patterns of human cancer and normal cell lines treated with glucose. Methods: Human gingival fibroblast (hGF), colorectal adenocarcinoma (HT29), and skin malignant melanoma (A375) cell lines were cultured and treated with additional glucose in three respective concentrations: 1 mg/ml, 5 mg/ml, and 10 mg/ml. Then, cell viability was measured using an MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide)-assay. The data were analyzed using the Statistical Package for the Social Sciences software. Results: The hGF cells’ percentage pattern of viability showed a rapid decline of nearly 95% on the third day of treatment. Both HT29 and A375 were able to survive in the high glucose condition when the cell viability percentage was above 100% on Day 5. The data exhibited significance; the p-value was less than 0.001. Conclusion: The high glucose concentration can be toxic to hGF. In addition, HT29 and A375 might be adaptive to the hyperglycaemic condition.

Abstract

Background: Fucose is a deoxyhexose sugar. While the biological roles of L-fucose remain unclear, the sugar is known to accelerate the malignant potential of cancer cells. Therefore, this study aimed to evaluate the viability pattern of human cancer and normal cell lines treated with fucose. Methods: The human gingival fibroblast (HGF-1), colorectal adenocarcinoma (HT-29) and skin malignant melanoma (A375) cell lines were cultured and treated with fucose at three concentrations of 1, 5, and 10 mg/ml. Cell viability was then measured using (3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay. The data were analyzed using Statistical Package for the Social Sciences software. Results: The percentage of HGF-1 cell viability showed a rapid decline after day 1 of treatment. HT-29 and A375 were capable of surviving treatment with high fucose concentrations. The data were highly significant at p < 0.001. Conclusion: Whereas a high concentration of fucose is toxic to the HGF-1 cell line, the HT-29 and A375 cell lines could potentially adapt to this condition. Down- or upregulation of certain molecules that could induce or inhibit cell death may explain such adaptation. Further testing of up- and downregulated molecules should be conducted in future work.
