Abstract

Background: Cervical cancer is one of the leading-cancers affecting women. Cancer drugs that do not originate from natural ingredient, chemotherapy drugs, have side and resistant effects. Thus study about the natural products treating cancer cells is needed. Secondary metabolites isolated from sponge-associated fungi are expected to have a potency to fight cancer cells. In addition, the production of anticancer compounds from microorganisms has several advantages, including rapid growth and can be manipulated to increase productivity. The isolation and testing cytotoxicity against 3 fungal isolates from Yogyakarta have been done on the previous research. All three isolates have a potential candidate as anticancer drug. Aims: The purpose of this advanced study was studying bioactive compounds induced apoptosis pathway of sponge-associated fungi against cervical cancer HeLa cells. Methods: This study has been carried out for approximately 5 months. The method conducted in this research including the sponge cultivation (covers growth and isolation of secondary metabolites), the mycelium extraction of fungi, the cytotoxicity assay against HeLa cells using MTT Assay and Apoptosis Staining was to see the induction of apoptosis pathway. Results: Based on the research showed that ethyl acetate extract from mycelium is 0.22 grams. The cytotoxicity assay from mycelium extract showed IC50 value of 164 μg/mL against HeLa cell line. Conclusion: The findings is carrying to a possibility to develop the extracts of sponge-associated fungi as candidate of anti-cancer compound. By apoptosis staining, showed the cells coloured green are still alive, and cells undergoing apoptosis have nucleus that appears orange to red. We assuming that the apoptosis was caused by the possibility of peptide compounds that induce apoptosis through the mitochondrial pathway, by increasing the activity of the protein expression of apoptosis, which are Bcl-2 and Bcl-xl.

Abstract

Hyperlipidemia results in excessive superoxide anion radicals that are the cause ofoxidative stress. Phytochemical compounds can reduce oxidative stress. The aim of thisstudy was to investigate the correlations between ratio of Nrf2/Keap1 and catalase geneexpression in livers of hyperlipidemic rats after administration of 7-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-chromen-4-one. Twenty-four Rattus norvegicus rats, aged 8 weeks andweighing an average of 200 g were randomly divided into 6 groups i.e. Group 1 wasnormal group (N), Group 2 was hyperlipidemic rats (HL), Group 3 was hyperlipidemicrats with simvastatin (HL+SV), and Groups 4-6 were hyperlipidemic rats with 7-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-chromen-4-one doses 10 mg (HL+10), 30 mg (HL+30) or 90 mg/200 g BW (HL+90), respectively, administered orally by gavages. At the end ofthe study, the rats were euthanized and the livers were used to analyze the ratio of Nrf2/Keap 1 and catalase gene expression. Nrf2/Keap1 ratio and catalase gene expressionbetween groups were analyzed by Kruskal Wallis test. Spearman’s correlation test wasused to analyze the correlations between Nrf2/Keap1 ratio and catalase gene expression.The administration of 3 different doses of 7-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-chromen-4-one on hyperlipidemic rats increased catalase gene expression. There wasno correlation between ratio Nrf2/Keap1 and catalase gene expression. In conclusion,administration of 7-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-chromen-4-one can improvecatalase gene expression in hyperlipidemic rats. However, there is no correlation betweenthe ratio of Nrf2/Keap1 gene expression and the catalase gene expression.
