Abstract

Antioxidants are agents that can reduce free radicals. Parijoto fruit (Medinilla speciosa) contains flavonoids that could act as an antioxidant. However, those flavonoids are water-soluble and show low bioavailability. Nanotechnology is a potential approach to improve the bioavailability of flavonoids from Parijoto fruit. This study was conducted to determine the antioxidant activity of parijoto nanoparticles with variations of the chitosan, alginate, and chitosan/alginate encapsulants. Secondary metabolites of parijoto fruit were using the maceration method. The synthesis of parijoto nanoparticles was conducted using the ionic gelation method with chitosan, alginate, and chitosan/alginate encapsulation. Parijoto nanoparticle size and distribution were characterized using Particle Size Analyzer (PSA). The formation of nanoparticles in colloids was determined as a percent. The antioxidant activity of nanoparticle was evaluated using Ferric Reducing Antioxidant Power (FRAP) method using a UV-Vis spectrophotometer. Chitosan encapsulation produced nanoparticles with a size of 269.3 nm, pdI 0.372 and transmittance 99.379%. Alginate encapsulation produced a particle size of 366.4 nm, pdI 0.589 and transmittance 99.690%. The combination of chitosan/alginate encapsulants produced a particle size of 187.00 nm, pdI 0.239 and transmittance 99.894%. Parijoto nanoparticles obtained from chitosan, alginate, and chitosan/alginate encapsulant showed strong antioxidant powers indicated by IC50 values 2.442±0.047 ppm, 3.175±0.169 ppm and 2.115±0.045 ppm, respectively. Altogether, our study shows that parijoto nanoparticles are potent as antioxidant agents.Keywords: Alginate, antioxidant, chitosan, FRAP, Medinilla speciosa, nanoparticle

Abstract

TNBC, one of the sub type of breast cancers was widely known with high tumorigenic and poor prognosis than others. The development of combination agent (co-chemotherapy) with doxorubicin for chemotherapy of TNBC were carried out to decrease doxorubicin side effect and resistance in cancer. This present study aims to explore the co-chemotherapeutic properties of PGV-0 and investigate induction of doxorubicin on apoptosis, senescence and ROS against TNBC. 4T1 Cell line were used as a TNBC in vitro model. Cytotoxic measurement was performed using MTT assay resulting in IC50 values of 52 μM. Meanwhile, the combination of doxorubicin and PGV-0 showed synergistic effect which decreased cell viability of 4T1 better than single treatment of doxorubicin. Apoptosis analysis was performed using annexin V/PI assay indicated that the combination treatment of PGV-0 and doxorubicin increased apoptosis evidence. Senescence detection was carried out using senescence-associated-β galactosidase (SA-β-gal) assay. The results showed that a single treatment of PGV-0 induced cellular senescence and increased senescence cells in combination treatment. Moreover, DCFDA staining showed that PGV-0 increased ROS level at single treatment, whereas combination treatment increased ROS intracellular compared to the positive control of doxorubicin. Based on these results, PGV-0 has potential as a co-chemotherapeutic candidate on TNBC.Keyword: 4T1, PGV-0, Co-chemotherapy, Cytotoxic, Senescence, Apoptosis, ROS

Abstract

Fetal bovine serum (FBS) is a gold standard as a supplement to cell and tissue culture media. This is due to a large number of Growth Factor (GF) contained in FBS. However, the use of FBS is at risk of transferring endotoxins, prions, bacteria and viruses from animals to humans, so it is risky to be used on cell therapy. Human Platelet Lysate (HPL) is a medium that can be developed as an alternative cell growth medium. The advantage of HPL is that it does not contain aggregate platelets so it does not cause the cells to clot. This condition causes HPL to be used as a substitute medium replacing FBS for cell propagation. The use of HPL for cell propagation has been widely reported. However, the use of HPL in cancer cells has not been found. Thus, this study aims to see the effectiveness of HPL as a T47D cell culture medium. The study began with donor selection with criteria for the male sex, the blood type O, the age ≤35 years. Furthermore, the Platelet Concentrate (PC) was processed into HPL then measured pH, total protein and albumin levels. The cell viability was measured using the MTT assay to determine the ability of cell proliferation when propagation using HPL. The doubling time test was carried out as in the cell proliferation test. However, the incubation was carried out for 24 h, 48 h and 72 h and the HPL concentration used was 5%. The result shows that HPL 10% and 20% ability to increase proliferation better than the FBS 10%. HPL with a 5% concentration ability to shortens the doubling time than FBS 10% (doubling time is less than 19.94 h). It this study, cell proliferation is influenced by the pH of HPL and total protein but not by the amount albumin.Keywords: Human Platelet Lysate, Proliferation, T47D cell line, total protein, albumin.

Abstract

Hyptis pectinata (L.) poit, popularly known in the world as “comb bushmint” is a medicinal plant commonly used for the treatment of throat and skin inflammations, bacterial infection, pain and cancer. The objective of this research is to determine the cytotoxic and antiproliferative effect under Hyptis pectinata ethanolic extract (HPE) treatment on breast cancer cells. The effect HPE of on cytotoxicity was examined by MTT assay on MCF-7 breast cancer cells. This assay also used to determine cell proliferation over 3 days of treatment with 1.5 – 100 µg/mL HPE. HPE showed that exhibited cytotoxic effects with IC50 value of 30 µg/mL for 24 hours and changes the physiological morphology on MCF-7 cells. Interestingly, the treatment of HPE for 48 and 72 hours highly decreases cell viability on MCF-7 with dose and time-dependent manner compared to untreated cells. These results indicate that HPE has antiproliferative activities and maybe the potential to be developed as a natural chemotherapeutic agent.Keywords: Hyptis pectinata (L.) poit extract, cytotoxicity, antiproliferative, MCF-7 cells

Abstract

As one of the leading causes of death in worldwide, cervical cancer requires the effective therapies to reduce its mortality rate. One of the chemotherapy agents that frequently used in the treatment is cisplatin. However, due to drug resistance and its side effects, an agent that can be combined with cisplatin is needed. Parijoto fruit (Medinilla speciosa Reinw.ex.Bl) contains secondary metabolites compounds that have potential as anticancer. The study aims to determine the cytotoxic effect of methanol extract of Parijoto fruit calculated from the IC50 value and the synergicity of the combinational treatment with cisplatin evaluated from the Combination Index (CI) value and its cell viability by using MTT assay. Results showed that methanol extract of Parijoto fruit (MEP) performed cytotoxic effect on HeLa cell line with IC50 of 209.6 μg/mL while the value of IC50 of cisplatin against HeLa cells amounted to 12.8 μg/mL. The combination of 26.205 ppm (1/8 IC50) of MEP and 1.601 ppm (1/8 IC50) of Cisplatin performed synergistic effect on HeLa cell line with the CI value of 0.69. From the above results, it can be concluded that MEP is potential as co-chemotherapy agent based on the synergistic cytotoxicity effect with cisplatin.Keyword: cytotoxic, Medinilla speciosa, cisplatin, co-chemotherapy, MTT

Abstract

The utilization of natural resources, one of which is plants, has been researched as an alternative to synthetic drugs because of their natural content. Potato (Solanum tuberosum L.) peels, the parts of potatoes that are often cut off and discarded, have been reported to have some phenolic compounds and flavonoids in their composition. The extract of potato peels was investigated for its analgesic, anti-inflammatory, and anti-biofilm-forming properties. A hot plate test was conducted to assess the analgesic activity in treatment doses of 50 mg/kg, 100 mg/kg, and 200 mg/kg with paracetamol as the reference drug and distilled water as the negative control, while carrageenan-induced paw edema was used to assess anti-inflammatory activity in treatment doses of 100 mg/kg, 200 mg/kg, and 400 mg/kg with diclofenac as the reference drug and distilled water as the negative control. Anti-biofilm-forming activity was tested by using the crystal violet assay. The results showed that, compared with the negative control, treatment doses of 100 mg/kg and 200 mg/kg significantly (p < 0.05) reduced pain stimuli, whereas a treatment dose of 100 mg/kg, 200 mg/kg, and 400 mg/kg significantly (p < 0.05) reduced the edema volume increment. However, compared with the positive control, paracetamol and diclofenac were associated with the least pain stimulus and the least edema volume increment, respectively. Potato peel extract against S. mutans biofilm formation demonstrated effectiveness (p < 0.05). Based on these data, it can be concluded that potato peel extract has analgesic, anti-inflammatory, and anti-biofilm-forming activities, as demonstrated in this study.

Abstract

One of the main modalities of cancer treatment is chemotherapy, which uses chemicals that are generally electrophilic. These xenobiotic compounds sometimes does not produce effective response due to activity of glutathione S-transferase (GST) which inactivate the xenobiotics. Several natural phenolic compounds were reported to inhibit GST activity in vitro. Noni fruit (Morinda citrifolia L.) which contains flavonoids and other phenolic compounds such as scopoletin and morindon is proposed to interfere GST activity. This study aimed to analyze the effect of ethanolic extract of Noni fruit in vivo on GST activity in lung rat using 1,2-dichloro-4-nitrobenzene (DCNB). This substrate is a specific for class mu GST. First, rats were administered with ethanolic extract of Noni and dimethylbenz(α)anthracene (DMBA) for two weeks. The cytosolic fraction of lung was isolated then the GST activity was determined by simple kinetic program which was automatically calculated using spectrophotometer. The results showed that ethanolic extract of Noni in 1 and 5% (w/v) of concentration induced class mu GST activity, whereas 10% (w/v) of concentration inhibited class mu GST activity. After a treatment with DMBA, all tested concentrations of ethanolic extract of Noni inhibited class mu GST activity of lung rat significantly. These results indicated that Noni fruit extract can be further developed as a supportive agent of a chemotherapy drug.Keywords: DMBA, GST, Morinda citrifolia L., spectrophotometer.
