Abstract

Background: Diabetes mellitus is a metabolic disease, characterized by hyperglycemia due to disturbance in both insulin secretion and function. One of theurapeutic approaches is to reduce blood glucose levels by inhbiting α-/β-glucosidase and α-amylase involved in carbohydrate digestion. Thus, inhibition of these enzymes play important role in the treatment of diabetes mellitus. Roselle (Hibiscus sabdariffa L.) has been known to have several medicinal properties and potency as an antidiabetics agents. This reseacrh aimed to observe antidiabetic properties of roselle ethanol extract (REE) towards α-glucosidase, β-glucosidase and α-amylase.Materials and Methods: REE was done with maceration technique using diluent of 70% ethanol. Antidiabetic properties were measured by inhibitory activity of α-amylase, α-glucosidase and β-glucosidase.Results: REE was able to inhibit α-/β-glucosidase and α-amylase in the highest concentration with inhibition percentage of 72.68, 47.34 and 73.08% respectively, and were comparable with Acarbose of 81.49, 50.97, 73.08%. The median inhibitory concentration (IC50) of α-/β-glucosidase and α-amylase of REE were 15.81, 41.77, 18.09 μg/mL respectively, and Acarbose were 9.45, 22.57, 3.64 μg/mL respectively.Conclusions: REE inhibits α-/β-glucosidase and α-amylase.Keywords: Roselle, Acarbose, α-glucosidase, β-glucosidase, α-amylase, antidiabetic

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: 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: Mesenchymal stem cells (MSCs) are the cells which have high renewal capacity and and are capable for differentiating into some types of cells. MSCs can be obtained from several tissues including bone marrow, synovial membrane, blood, adipose tissue and periosteum. The proliferation and self-repair ability of MSCs are the advantages to use as stem cells-based therapy of various diseases. The aim of this study was to determine the differentiation, characterization and proliferation of synovial membrane-derived MSCs (SM-MSCs).Materials and Methods: The cells proliferation capacity was determined by cell counting using trypan blue, characterization of MSCs (cluster of differentiation (CD)90, CD11b, CD73, CD34, CD19, CD45, CD105 and human leukocyte antigen-DR isotype (HLA-DR)) using flow cytometry analysis, and differentiation capability into three lineage cells was determined with red alcian blue, oil red O and alizarin staining.Results: The type culture of SM-MSCs was adherent and showed positive CD44, CD105, CD73, CD90 and negative of CD19, HLA-DR, CD11b, CD45, CD34 surface marker. Based on the result, SM-MSCs P3 showed differentiation potency into adipogenic, chondrogenic, and osteogenic lineage cells. The population doubling time of SM-MSCs has increased from P3 to P8. The population doubling time of SM-MSCs P3 was 1.69 days and SM-MSCs P8 was 3.64 days.Conclusion: The results indicated that SM-MCSCs from osteoarthritis patients are able to differentiate into osteocytes, chondrocytes, adipocytes and highly express of CD105, CD73, CD90, CD44 and negative for CD34, CD45, CD14, CD19.Keywords: synovial membrane, mesenchymal stromal cells, adipocyte, chondrocyte, osteocyte

Abstract

Recent research has demonstrated that mesenchymal stem cells (MSCs) potentially benefit and enhance coronavirus disease (COVID-19) recovery. This benefit occurs via a mechanism that promotes viral clearance by phagocytes and macrophages. This action occurs through the innate (increase in IL-10 production and decrease in TNF-α and IL-12 production) and the adaptive immune system (decrease in IL-17 production, promote regulatory T cell proliferation and inhibit effectors T cell proliferation). MSCs are expected to act as an anti-inflammatory in the hyper-inflammatory state of COVID-19. MSCs enhance immune cell replacement that have been overwhelmed or have been lost due to cytokine storm. Although vaccines are the answer to this pandemic, MSCs can improve COVID-19 patients, especially in patients with chronic illnesses. The focus on keeping death-rates low is a great opportunity for MSCs-based therapy for severe or critically ill patients. MSCs and conditioned medium have the potential to serve as adjunctive therapy in preventing the body's overactive defense response or the so-called cytokine storm caused by COVID-19.Keywords: adjuvant therapy, COVID-19, mesenchymal stem cells, secretome

Abstract

Combining chemotherapeutic agents such as doxorubicin with herbal products or other compounds that can enhance cytotoxicity without side effects is required. Thus, we aimed to observe the cytotoxicity of doxorubicin and sesoot (Garcinia picrorrhiza) fruit ethanolic extract (GpKar) on human fibroblast cells, BJ. This study used a post-test-only control randomized group design with n=3 and a number group of 5. The method used in this research is cell number, and viability was measured with (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium assay. Treatments consisted of a combination of doxorubicin (0.02 μg/ml) and GpKar of 66.47 µg/ml (DES1), 132.94 µg/ml (DES2) and 265.89 μg/ml (DES3). The data were analyzed using a one-way ANOVA and Duncan post hoc tests. DES3 showed the lowest viability among treatments (89.32%). DES1 and DES2 showed high viability (>90%), 97.93%, and 95.08%, respectively. Thus, the combination of doxorubicin (0.02 μg/ml) and GpKar (66.47 µg/ml) was considered safe for further use in the following assay. In summary, the combination of doxorubicin and GpKar showed high viability in normal fibroblast cells.
