Introduction: Cancer is a non-communicable disease with over 18.1 million new cases and 9.6 million deaths annually according to WHO. Breast cancer is the number two highest count type of cancer trailing behind lung cancer. Treating cancer is expensive and have various side effects. Active components found in plants or fungi that have antioxidant and cytotoxic activity towards cancer cells, could be an alternative for anticancer. One of the fungi that is potentially developed as an anticancer, are the genus of Auricularia sp. also known as black-white fungus. This study aims to determine the phytochemicals components, antioxidant activity and cytotoxic effect of the Auricularia sp. towards MCF-7 breast cancer cells. Methods: Dried black-white fungus of Auricularia sp. grinded into a fine powder. Then, multilevel maceration is done with the n-hexane, ethyl acetate, ethanol as solvents. The extracts of black-white fungus undergo phytochemical screening and thin layer chromatography (TLC), followed by measuring antioxidant and evaluating the cytotoxic activity towards MCF-7 breast cancer cells. Results: black-white fungus of Auricularia sp. contained secondary metabolites of flavonoids, alkaloids, and triterpenoids and a total of 17 other phytochemical components. Ethyl acetate extract of black-white fungus showed a weak antioxidant activity towards DPPH free radical with IC50 of 215.51 μg/mL and a very active cytotoxic activity on MCF-7 cells with IC50 of 0.21 μg/mL. On the other hand, ethanol and n-hexane extracts of black-white fungus are categorized with an active cytotoxic activity on MCF-7 cells with IC50 of 29.28 μg/mL and 50.39 μg/mL, respectively. Conclusion: Black-white fungus Auricularia sp. that had anticancer activity towards breast MCF-7 cells should be considered as an alternative treatment for breast cancer therapy.

Background: Chronic kidney injury produced free radicals. In a previous study, the ethanolic extract of binahong leaves (Anredera cordifolia (Ten.) Steenis) has a flavonoid content, quercetin, a protective free radical effect. This study aims to determine the impact of binahong leaves against chronic kidney damage in Sprague Dawley rats. Results: To this end, we developed a chronic kidney injury animal model by Unilateral Ureteral Obstruction (UUO) method. We randomly divided rats into six groups. Group I is the Sham group; Group II is the negative control group; Group III is the positive control group (losartan 1.18 mg/kg BW); Group IV is Dose I of binahong leaves extract 75 mg/kg BW); Group V is Dose II binahong leaves extract 150 mg/kg BW); Group VI is Dose III binahong leaves extract 300 mg/kg BW). We administered losartan and binahong extracts on day 14 after UUO treatment. The plasma was examined for the superoxide dismutase (SOD) enzyme activity, catalase enzyme activity, and malondialdehyde (MDA). All statistical analyzes were processed using the Statistical Program of Social Sciences (SPSS) software for Windows, version 16. The measured values of the parameters were expressed in mean {\textpm} SD. The difference test between groups was evaluated by ANOVA (Analysis of Variance) followed by LSD (Least Significant Difference) with a degree of significance (p) \<0.05 if the data distribution was normal and homogeneous. If the distribution of data is not normal and not homogeneous use non-parametric Kruskal Wallis analysis. Results: The results showed that UUO produced high MDA levels, whereas SOD activity and catalase activity were decreased compared with the Sham group. Administration of binahong extracts could reduce the MDA amount and increased the SOD and catalase activity. Conclusion: Binahong leaves extracts showed antioxidant activity to prevent kidney injury in UUO model rats.

Background: Acute kidney injury (AKI) is a kidney disease resulting in high morbidity and mortality levels in humans. One of the disorders classified as AKI is ischemia-reperfusion injury (IRI), characterized by two phases. The first phase is Ischemia in the kidneys due to obstruction of the renal arteries or veins, followed by the second phase, which is the occurrence of reperfusion with blood flowing back in the renal arteries veins. The aim of this current research is to analyze the efficacy of Artocarpus altilis on Kidney ischemiareperfusion model rats. Methods: To this end, first, we established Ischaemia-reperfusion kidney injury rat. We then evaluated the Artocarpus altilis extract on IRI model rats. A total of 36 rats have grouped into six groups. Group I is the Sham group, Group II is the negative control group, Group III is the positive control group (vitamin C 100 mg/kg BW), Group IV is Dose I of Artocarpus altilis extract 50 mg/kg BW), Group V is Dose II Artocarpus altilis extract 100 mg/kg BW), Group VI is Dose III Artocarpus altilis extract 200 mg/kg BW). The vitamin C and Artocarpus altilis extract administered 14 days before and after Ischemia-reperfusion treatment. At day 0, Ischemia was made by bilateral renal pedicle clamping method for 30 minutes, sacrificed 14 days after reperfusion. The blood and histology samples were collected on day 0, a day after reperfusion, at 24 hrs after reperfusion, at 48 hrs after reperfusion, and 14 days after treatment. Results: The clamping duration of 30 minutes leads to achieving the most representative clinical IRI conditions. It shows the most significant recovery of injury conditions within the 14-day reperfusion period in IRI animal models, making it ideal for IRI operations for the preliminary test. The administration of 100 mg/kg BW of Artocarpus altilis extract could reduce the malondialdehyde plasma compared with the sham group. The SOD and Catalase activity showed improvement after reperfusion. Conclusion: Artocarpus altilis extracts showed antioxidant activity to prevent the kidney from ischemia-reperfusion injury by modulated SOD and Catalase.
