Abstract

Background: Breast cancer (BC) is the leading cause of death cancer in women. Cancer therapies using TNFα and IFNγ have been recently developed by direct effects and activation of immune responses. This study was performed to evaluate the effects of TNFα and IFNγ directly, and TNFα and IFNγ secreted by Conditioned Medium-human Wharton’s Jelly Mesenchymal Stem Cells (CM-hWJMSCs) toward apoptosis of BC cells (MCF7).Materials and Methods: BC cells were induced by TNFα and IFNγ in 175 and 350ng/mL, respectively. CM-hWJMSCs were produced by co-culture hWJMSCs and NK cells that secreted TNFα, IFNγ, perforin (Prf1), granzyme B (GzmB) for treating BC cells. The BC cells were treated with CM-hWJMSCs in 50%. The expression of apoptotic genes Bax, p53, and the antiapoptotic gene Bcl-2 were determined using RT-PCR.Results: TNFα and IFNγ at concentration of 350 ng/mL induced higher Bax expression compared to 175 ng/mL. TNFα and IFNγ 350 ng/mL, 175 ng/mL induced p53 expression, whilst TNFα and IFNγ at 350 ng/mL decreased Bcl-2 expression. Perf1, GzmB, TNFα and IFNγ-containing CM-hWJMSCs induced significantly apoptosis percentage, induced Bax expression, but did not effect p53, Bcl-2 expression.Conclusion: TNFα and IFNγ directly induce Bax, p53, decrease Bcl-2 gene expression. The Prf1, GzmB, TNFα, IFNγ-containing CM-hWJMSCs induce apoptosis and Bax expression.Keywords: breast cancer, Wharton’s Jelly mesenchymal stem cells, TNFα, IFNγ

Abstract

BACKGROUND: Oxidative stress is closely related to all aspects of cancer. Cosmos caudatus ethanolic extract (CCEE) has been proved to have antioxidant effect that inhibited cancer cell growth due to its bioactive compounds such as catechin, quercetin and chlorogenic acid. This study aimed to evaluate antioxidant and anticancer activity of CCEE and its compounds.METHODS: Total phenol was measured according to the Folin-Ciocalteu method. Catechin, quercetin and chlorogenic acid contained in CCEE were identified by high-performance liquid chromatography (HPLC). Antioxidant activity was evaluated by 2,2′-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS)-reducing activity, 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity, and ferric reducing antioxidant power (FRAP) activity test. The cytotoxic activity of CCEE was determined by MTS [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium] assay on HeLa cells.RESULTS: The result showed that total phenol of CCEE was 181.64±0.93 µg Cathecin/mg extract. ABTSreducing activity test showed that catechin had the highest activity (2.90±0.04 µg/mL), while CCEE had moderate activity compared to other compounds. FRAP activity test demonstrated that catechin had the highest activity (315.83 µM Fe(II)/µg) compared to other compounds. DPPH scavenging activity of CCEE was 22.82±0.05 µg/mL. Cytotoxicity test on HeLa cell showed that CCEE had lower activity (inhibitory concentration (IC)50= 89.90±1.30 µg/mL) compared to quercetin (IC50 = 13.30±0.64 µg/ mL).CONCLUSION: CCEE has the lowest antioxidant activity compared to quercetin, catechin, and chlorogenic acid and has the lowest anticancer activity compared to quercetin. However, CCEE and its compounds has potential as antioxidant and anticancer properties.KEYWORDS: antioxidant, anticancer, catechin, Cosmos caudatus, quercetin

Abstract

Kanker termasuk kelompok penyakit tidak menular (non-communicable diseases atau NCD) dan penyebab kematian terbesar di dunia. Salah satu faktor yang memengaruhi perkembangan kanker adalah reseptor NKG2D (natural-killer group 2, member D) merupakan kompleks reseptor yang mengaktivasi sel NK dan penting dalam immunosurveilance kanker. Brokoli, sayuran golongan Cruciferae, mengandung glukosinolat dan isotiosianat. Glukosinolat akan dihidrolisis oleh mirosinase (thioglucodase β) dan membentuk senyawa isotiosianat. Senyawa isotiosianat penting untuk mencegah kanker adalah senyawa sulforafan. Tujuan penelitian adalah menilai efek brokoli dalam meningkatkan ekspresi reseptor NKG2D dalam rangka memperbaiki aktivitas sel NK untuk mencegah kanker. Penelitian ini bersifat prospektif eksperimental laboratorium bersifat komparatif yang dilakukan di Laboratorium Aretha Medika Utama pada Februari–Juli 2016. Brokoli di-freeze dryer dan dibuat tepung dua konsentrasi, yaitu 50 μg/mL dan 25 μg/mL. Penelitian diawali dengan perbanyakan sel NK (cell line), kemudian dilanjutkan dengan perlakuan selama 24 jam dan penilaian ekspresi gen NKG2D menggunakan qPCR. Data penelitian ekspresi gen NKG2D dihitung dengan rumus Livak dan dianalisis menggunakan uji ANOVA satu arah dan uji lanjutan Tukey (SPSS 16). Pemberian brokoli konsentrasi 50 μg/mL dan 25 μg/mL meningkatkan level ekspresi gen NKG2D yang mengindikasikan peningkatan aktivitas sel-sel NK. Simpulan penelitian ini adalah pemberian brokoli meningkatkan aktivitas sel-sel NK dalam mencegah dan melawan sel-sel kanker.INCREASED NKG2D GENE EXPRESSION OF NKG CELLS BY BROCCOLI TO PREVENT CANCERCancer is the non-communicable diseases (NCD) and the biggest cause of death in the world. One of the factors that affect cancer development is NKG2D receptors (natural-killer group 2, member D) is a receptor complex that activates NK cells and is important in cancer immunosurveilance. Broccoli, Cruciferae vegetable, contains glucosinolate and isothiocyanate. Glucosinolate will be hydrolysed by the mirosinase (thioglucodase β) and form the isothiocyanate compound. Isothiocyanate compounds essential to prevent cancer are sulforafan compounds. The objective of the study was to assess the effect of broccoli in enhancing NKG2D receptor expression in order to improve NK cell activity to prevent cancer. This experimental study is a comparative true experimental laboratory, conducted in the Aretha Medika Utama in February to July 2016. Broccoli was freeze dryer and made two concentrations of flour, 50 μg/mL and 25 μg/mL. The study begins with multiplication of NK cells (cell line), then continued with treatment for 24 hours and assessment of NKG2D gene expression using qPCR. NKG2D gene expression research data was calculated by Livak formula and analyzed using one-way ANOVA test and Tukey's advanced test (SPSS 16). The administration of broccoli concentrations of 50 μg/mL and 25 μg/mL increased the level of NKG2D gene expression, indicating an increase in NK cell activity. The conclusion of this study is the provision of broccoli increases the activity of NK cells in preventing and fighting cancer cells.
