    Antioxidant activities of inula viscosa extract and curcumin on U87 cells induced by beta-amyloid
    (Cukurova Univ, Fac Medicine, 2021) Alizade, Ares; Ozbolat, Guluzar
    Purpose: The aim of this study was to investigate the effects of Inula viscosa extract and Curcumin on the U87 (human astrocytoma cell line) treated with amyloid-beta (A beta), which is the Alzheimer's disease (AD) model cell line. Materials and Methods: Firstly, the cytotoxic potential of inula and curcumin was investigated in the U87 cells by the colorimetric MF1 (3-4,5-dimethyl-thiazolyl-2,5-diphenyltetrazolium bromide) assay. Then, the amount of Total Glutathione, Malondialdehyde (MDA), Glutathione reductase (GR) activities were investigated. ELISA test was used to examine the expression and activity of cleaved Bax and Bcl-2 proteins in the Inula viscosa and Curcumin treated U87 cell lines. Results: Inula viscosa and Curcumin treatment reduced cell death caused by amyloid-B in cells. It also reduced oxidative stress caused by amyloid-B, while reducing the activation of the proapoptotic protein Bax, and Bcl-2. Conclusion: Our results suggest that inula viscosa may represent a new approach in the treatment of Alzheimer's.

    IN VITRO EFFECTS OF ANTIOXIDANT AND PROAPOPTOTIC ACTIVITIES OF THYMOQUINONE IRON COMPLEX
    (Dokuz Eylul Univ Inst Health Sciences, 2022) Ozbolat, Guluzar; Alizade, Ares
    Introduction: This study aimed to investigate the proapoptotic and antioxidant effects of the Thymoquinone (TQ) iron complex on the SW480 cell line. This study investigates the proapoptotic and antioxi-dant effects of the TQ iron complex on the SW480 cell line. Material and Methods: The SW480 cells were routinely cultured in a medium for 48 h. and incubated at 37 degrees C in a 5% CO2 in the air. After the incubation period, the cells were washed with buffer, and 100 ml of the denaturing lysis buffer per 0.5 was added to 2x10(7) cells for 15 min, and supernatants were tak-en. ELISA test was used to examine the expression and activity of GADD153, Wee1, cleaved Caspase-3, Bax, GRP78, and Bcl-2 proteins in SW480 cells. In this study, to measure activities of total antioxidant capacity (TAS), catalase (CAT), total oxidant capacity (TOS), and superox-ide dismutase (SOD) activities were investigated by the ELISA method in cell lines SW480 treated with the TQ iron complex. Results: ELISA test results indicated that the activities of apoptotic proteins Bax, Wee1 Caspase-3, GADD153, GRP78, and Bcl-2 in human SW480 cell lines were significantly increased in the 48-hour treatment. Conclusion: Our results of this study demonstrated that in untreated cultures, high TAS, SOD and CAT ac-tivities were found in SW480 cell lines than in control cell lines.

    In vitro evaluation of the protective effects of Curcumin and Resveratrol against U87 Cells Induced by Beta-Amyloid
    (Bolu Abant Izzet Baysal Üniversitesi, 2022) Alizade, Ares; Özbolat, Gülüzar
    Objective: In this study we aimed to investigate the effects of curcumin and resveratrol antioxidant enzymes in ß-amyloid (Aß)-induced in vitro Alzheimer's Disease (AD) cell model. Materials and Methods: Three groups were created in this study; The control group consisted of U87 cells, the Aß group which was the in vitro AD model formed from the ß-amyloid-induced U-87 cell lines, and the Aß+ Curcumin+ Resveratrol group by adding curcumin and resveratrol to the Aß group. Cell viability in groups was evaluated with the 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) test. Total Antioxidant Level (TAS), Superoxide dismutase (SOD), Total Oxidant Level (TOS), and Catalase (CAT) enzyme levels, results were analyzed in order to evaluate the antioxidant levels.Results: When cell viability was evaluated, it was determined that curcumin and resveratrol did not have cytotoxic effects. TAS levels were statistically higher in the Aß+ curcumin and resveratrol group compared to the Aß group (p<0.05) and TOS levels were found to be significantly low in the Aß+ curcumin and resveratrol group compared to the Aß group (p<0.05). However, when compared to the control group, CAT and SOD enzyme levels were statistically and significantly low in the Aß group. In contrast, these enzyme levels were found significantly higher in the Aß+ curcumin and resveratrol group in comparison with the Aß group (p<0.05).Conclusion: In conclusion, it has been shown that curcumin and resveratrol support antioxidant activity.

    IN VITRO STUDIES ON THE PROTECTIVE EFFECT OF TANNIC ACID OF U87 CELLS INDUCED BY BETA-AMYLOID
    (Dokuz Eylul Univ Inst Health Sciences, 2021) Ozbolat, Guluzar; Alizade, Ares
    Background: While the prevalence of Alzheimer's disease continues to increase throughout the twentieth century, the cause and pathology of the disease are not well understood and scientists are seeking treatments for the disease. Tannic acid can be used effectively to treat Alzheimer's disease and seems to be one of the alternative therapeutic strategies in medicine. In this study, we aimed to investigate the effects of tannic acid on the U87 (human astrocytoma cell line) treated with amyloid-beta (A beta), which is the Alzheimer's disease (AD) model cell line. Materials and Methods: In the study; three groups were formed as the control group, the A beta group, and the A beta + tannic acid group obtained by adding tannic acid to the A beta group. Firstly, the cytotoxic potential of TA in U87 cells was investigated by the colorimetric MTT (3-4,5-dimethyl-thiazolyl-2,5 diphenyltetrazolium bromide) test. To determine the antioxidant status in the cell line treated with tannic acid, to examine the effects of total oxidant status (TOS), superoxide dismutase (SOD), total antioxidant status (TAS) and catalase (CAT) activities, were measured by the ELISA method. Results: In our study, the viability and proliferation of the cell decreased in U87 cells treated with amyloidB compared to the control group, but tannic acid increased cell viability and proliferation when compared with the group treated with amyloid-B. When compared to the control group, the TAS, SOD, and CAT levels were significantly decreased in the U87 cell line exposed to A beta; TOS levels were found to increase significantly. Conclusions: In in vitro experiments, we determined that tannic acid has a protective effect by increasing antioxidant parameters in the amyloid beta-induced cell line.

    Investigation of apoptotic effects of D-pantothenic acid on PC-3 prostate cancer cells
    (Cukurova Univ, Fac Medicine, 2020) Alizade, Ares; Ozbolat, Guluzar
    Purpose: The anti-inflammatory and antioxidant properties of D-pantothenic acid have been demonstrated and the effects of dexpentanol on inflammatory pathways and apopototic pathways that trigger cell death are of interest. Apoptotic pathways are important in resistance to chemotherapeutics in cancer diseases and in cancer development. Therefore, we planned how treatment of PC-3 human prostate cancer cells with dexpanthenol will affect the levels and activities of apoptotic and inflammation mediators. For this purpose, human prostate cancer cell culture was performed. Materials and Methods: The human prostate cancer cells were treated with dexpentanaol then protein levels and activities of inflammatory and apoptotic pathway mediators such as gadd153, AIF, grp78, bax and bcl-2 in the cells were analyzed by ELISA. Results: The results of our study showed that, Dpantothenic acid did not statisticaly decreased the leves of bax, bcl-2 and grp78 protein expression in PC-3 prostate cancer cells. The effect of D-pantothenic acid on gadd153 and AIF proteins in PC-3 cells was increased but this increased level did not statisticaly significant. Conclusion: Recent studies have demonstrated the potential benefits of anti-inflammatory drugs. Our study showed that D-pantothenic acid had no significant effect on the growth of PC-3 cells and has no significant effect on intracellular apoptotic pathways.
