It accepts original papers on clinical and experimental research that are pertinent in the biomedical sciences. The Journal is published 4 issues/year (i.e., Mar, Jun, Sep, and Dec). Background Rhuematoid arthritis (RA) is associated with infl ammation of the synovial membrane which results in an abnormal proliferation and resistance to the apoptosis process in synovial fi broblasts leading to synovial hyperplasia and joint destruction. Reversal of apoptosis resistance of fi broblasts in RA synovium is one of the targets for suppression of RA pathogenesis. Objectives This study aimed to investigate the apoptosis-inducing effects of crude extract of red jasmine rice (CE) on proinfl ammatory cytokine-stimulated apoptosis resistance in a human synovial sarcoma cell line (SW982). Methods SW982 cells were preincubated for 6 hours with combined cytokines, tumor necrosis factor-α (TNF-α), and interleukin 17-A (IL-17A). That was followed by the addition of CE at a concentration of 12.50-100 μg/ml. After either 24 or 48 hours of incubation, expression of apoptotic related genes, including the FLICE-like inhibitory protein gene (FLIP), the anti-apoptotic gene (Bcl-2), and the pro-apoptotic gene (Bax), was determined by real-time PCR. Expression of the apoptotic cells was determined by fl ow cytometric analysis and the caspase-3 activity was analyzed by ELISA. Results The expression of the apoptosis resistance markers, FLIP and Bcl-2/Bax ratio, was signifi cantly elevated when the cells were treated with the combined cytokines compared with the control group. These markers were signifi cantly decreased when co-treated with CE. These results were concomitant with a rise in caspase-3 activity and an increase in apoptotic cells when compared to the cytokine-treated group. Conclusions CE reduces cytokine-induced apoptotic resistance in SW982 cells via down regulation of the expression of anti-apoptotic genes. These results suggest application of CE is an alternative treatment of RA. 2019-05-07T10:02:39Z 2019-05-07T10:02:39Z 2018 บทความวารสาร 0125-5983 https://www.tci-thaijo.org/index.php/CMMJ-MedCMJ/article/view/111921/87285 http://cmuir.cmu.ac.th/jspui/handle/6653943832/65080 Eng Faculty of Medicine, Chiang Mai University |
