ABSTRACT
Breast cancer is one of the most common types of cancer causing high mortality rates among women worldwide. This study was aimed to evaluate the effect of Pistacia terebinthus (terebinth) resin extract (TRE) on the MDA-MB-231 breast cancer cell line. In the study, the cytotoxic dose of the resin extract in MDA-MB-231 cells was evaluated by MTS analysis. The effect of TRE on apoptosis was examined by Hoechst staining. Caspase-3 and cleaved caspase-3 protein expressions were determined by western blot analysis. Based on the outcomes of our MTS analysis, the IC50 dose of TRE was calculated at 56.54 µg/mL during a 24-h application period. With Hoechst staining analysis, an increase was observed in cells that underwent apoptotic change at 10 and 100 µg/ml TRE concentrations compared to the control. At 25 and 50 µg/mL TRE concentrations, no apoptotic change was found in comparison to the control; however, a significant drop in the number of viable cells was observed because 200, 300, and 500 µg/mL TRE concentrations were above the toxic dose. The caspase-3 protein expression level was significantly higher in cells treated with 100 µg/ml TRE compared to the control group, while there was no significant change in cleaved caspase-3 protein expression. It was thought that P. terebinthus resin might cause cell death in MDA-MB-231 cells via caspase-independent apoptosis pathway or other cell death pathways, and it was concluded that it could be a supportive treatment for breast cancer treatment.
ABSTRACT
Background: We aimed to determine the nutrient intake of Crohn's patients and to expose its relationship with Crohn's Activity Index (CDAI), Subjective Global Assessment (SGA) and Body Mass Index (BMI). Methods: This randomized controlled trial was conducted on patients enrolled in the Gastroenterology Polyclinic of a University Medical Faculty Hospital, Kayseri, Turkey in 2017. Two groups were included in this study: Crohn's Group (n = 100) and Control (n = 89). Crohn's Disease Activity Index was used to detect disease activity. Malnutrition risk was determined by the SGA and daily energy and nutrient intakes were calculated. Results: There was a significant relationship between SGA and both CDAI and BMI (P<0.001, P=0.008, respectively). Daily energy, carbohydrate, monosaccharide, starch, sucrose, fructose, poly-unsaturated fatty acids, omega-3 fatty acids, fiber, vitamin E and C, thiamine, niacin, pyridoxine, Mg, P, Fe, Cu, Zn intakes were significantly lower in Crohn's Group than in Control Group. While more than 50% of the patients did not consume enough, B6, C, thiamine, niacin, folic acid, Mg, Ca and fiber, intakes of vitamin E, riboflavin, Fe, P, and Zn were adequate. Energy and nutrient (vitamin E, thiamine, vitamin B6, mono and poly unsaturated fatty acids, saturated fatty acids, Mg, Ca, P, Zn, n-3 fatty acids and starch) intakes were negatively correlated with CDAI, but there was no relationship between these intakes and SGA. Conclusion: There was a relationship between CDAI, SGD and BMI used to determine nutritional status in patients with Crohn's.
