Abstract

Breast cancer (BC) is the number one cause of deaths from cancer in women. Metastasis in BC is caused by immunosurveillance deficiency, including impairment of Natural Killer (NK) cell maturation, low NK activity, and decreasing cytotoxicity. This study was performed to improve activating receptors and cytotoxicity of NK cells using interleukin 15 (IL15) against BC cells. Human recombinant IL15 was used to induce NK cells. To evaluate the potential of IL15 in inducing NK cells, we measured the activating and inhibiting receptors (NKG2D, NKG2A), apoptotic potency of NK cells on BC cells (MCF7) using transwell assay. The IL15 inducer on the NK cell were measured NKG2D, NKG2A gene expression with quantitative polymerase chain reaction (qPCR), (GzmB) secretion using ELISA, apoptotic gene expression of MCF7 using qPCR. IL15 increased NKG2D expression 4.01-9.13%, but IL15 could not affect toward NKG2A expression on NK cells. IL15-activated NK cells, inhibited BC cells proliferation, induced apoptotic BC cells 25.89-32.19%, induced apoptotic genes of BC cells bax, p53. IL15 increase NK activating receptor (NKG2D), inhibit BC cells proliferation, induce apoptotic percentage and induce apoptotic gene expression.

Abstract

Background: The excessive free radicals condition called oxidative stress can harmful for the body. To prevent and cure it, the antioxidant agents are required. Nowadays, the natural product extracted from plants have been widely used in folk medicine as antioxidant for the treatment of many diseases. Ficus elastica (rubber tree) has some compounds that has several biological activities, i.e., quercitrin, myricitrin, morin, and eleutheroside B. The F. elastica works against the free radicals and can be potential as antioxidant agent. The purpose of this study was to evaluate antioxidant properties of F. elastica ethanolic extract (FEE), quercitrin, myricitrin, morin, and eleutheroside B.Materials and Methods: The antioxidant activities of FEE and standard compounds were evaluated by free radical-scavenging activity of 2,2-diphenyl-1-picrylhydrazil (DPPH), hydrogen peroxide (H2O2), 2,2’-azinobis-(3-ethylbenzothiazoline- 6-sulfonic acid) (ABTS), and ferric reducing antioxidant power (FRAP) activities using spectrophotometry method.Results: FEE has the lowest of DPPH scavenging activity (IC50=13.82 µg/mL) than other compounds. In ABTS scavenging activity, FEE has moderate activity with IC50 value 23.29 µg/mL. In FRAP activity, FEE has moderate activity with value 241.58 µM Fe(II)/µg, while in H2O2 scavenging activity, FEE also show moderate activity with IC50=83.97 µg/mL compared to other compounds.Conclusion: In summary, FEE and the pure compounds (quercitrin, myricitrin, morin, and eleutheroside B) have potential as antioxidant agent.Keywords: free radical, morin, myricitrin, quercitrin, rubber tree, scavenging activities

Abstract

Background: Skin-aging is a progressive changes in the skin combine with cumulative extrinsic factors which are mostly caused by free radicals caused by exposure to lots of free radicals molecules from pollutant, wrongly food intake, or too much sun bathing. These free radicals can be tackled by a treatment using antioxidants. Prevention of aging can be done by escalating antioxidant intake. Protocatechuic acid (PCA) and Ferulic acid (FA) have been known for their scavenging properties on free radicals and antiaging activity. Antioxidant and antiaging activity of both compounds have not been compared comprehensively before. Hence, current study was conducted to compare the potential of PCA and FA for their antioxidant and antiaging activities using various methods.Materials and Methods: Antioxidant analysis of PCA and FA was conducted using H2O2 scavenging assay, 2,2’-azinobis-3-ethylbenzo-thiazoline-6-sulfonic acid (ABTS), 2,2-diphenyl-1-picrylhydrazil (DPPH), and ferric reducing antioxidant power (FRAP). Meanwhile, antiaging activities of PCA and FA were examined using inhibitory activities of tyrosinase, collagenase, elastase, hyaluronidase and tyrosinase.Results: IC50 of scavenging activity of ABTS were 125.18 µg/mL (PCA) and 35.55 µg/mL (FA), inhibition activity of collagenase were 126.16 µg/mL (PCA) and 52.85 µg/mL (FA) and inhibition activity of tyrosinase were 246.42 µg/mL (PCA), 253.58 µg/mL (FA).Conclusion: In conclusion, FA has better ABTS scavenging and collagenase inhibition activities compared to PCA. Meanwhile, PCA has better activity of tyrosinase inhibition than FA.Keywords: antioxidant, antiaging, ferulic acid, protocatechuic acid

Abstract

Background: Skin aging is a condition where skin is unable to retain both its physiological and structural integrity. Plants is the main source of phtytochemicals compound with wide range of biological activities. Through the efforts of ongoing scientific researches, an increasing number of plant extracts and phytochemicals have been showed promising result as anti-aging agent. Snake fruit (Salacca zalacca (Gaert.) Voss) is tropical plant belongs to the palm tree family (Arecaceae) that served as important crop in Indonesia. Despite its utilization, the phytochemical compound available in snake fruit, especially its peel have not been well documented. Present study aimed to elucidate the phytochemical constituent of snake fruit peel and its anti-aging potency.Materials and Methods: Snake fruit peel extract (SPE) was subjected to qualitative phytochemical assay, high performance liquid chromatography, and molecular docking towards protein related in skin aging.Results: The screening showed SPE contained phytochemical compound belong to flavonoid, tannin, phenol, triterpenoid, saponin and alkaloid. Thus, based on the analysis only chlorogenic acid was present in SPE whilst rutin and caffeic acid were not detected. The SPE was contained chlorogenic acid around 1.074 mg/g dry weight. Chlorogenic acid had the high binding affinity towards matrix metalloproteinase (MMP)-1 (-9.4 kcal/mol).Conclusion: Current findings may provide scientific evidence for possible usage of SPE and its compounds as antioxidant and anti-aging agent.Keywords: Salacca zalacca, phytochemical compound, high performance liquid chromatography, anti-aging
