Abstract

Flamboyant flower (Delonix regia) extract can increase proliferation and differentiation rates of mesenchymal stem cells (MSCs) into specific cells such as bone, nerve, and fibroblast cells. The extract possess metabolic compounds that may act as antibiotics, anti-inflammatory, antimicrobial, diuretic, anthelmentic, astringent, leucorrhoea, and potentially increase the body's metabolism normally. This study aimed to investigate expression level of alkaline phosphatase (ALP) by mice MSCs treated with flamboyant flower extract in vitro. Here, mice bone marrow cell cultures were treated with flamboyant flower extracts of 0.6 mg/ml (P1), 0.7 mg/ml (P2), 0.8 mg/ml (P3), and 0.9 mg/ml (P4). Untreated cell culture was used as negative control (P0). Expression of ALP gene was measured by RT-qPCR method. The results showed that mice mesenchymal stem cell could differentiate into bone, nerve, and fibroblast cells. The addition of flamboyant flower extract ranged from 0.6-0.9 mg/ml significantly (p<0.05) influenced the expression of ALP by differentiating MSCs. The highest expression was found at the stem cells treated with flamboyant flower extract of 0.8 mg/ml, 0.13 times compared with control. In conclusion, flamboyant flower extracts treatment might increase the expression of ALP in differentiating MSCs.  This information can be used as a basis for finding an appropriate biomarkers for tracking the differentiation and profileration of tissue originated MSCs induced by extracts of medicinal plants.

Abstract

COVID-19 caused by SARS-CoV-2 poses a major threat to the global community, particularly in Indonesia. Countermeasures to prevent the spread of this disease have also been implemented, including the implementation of a vaccination program. An immunoassay technique that can be used to analyze antibodies that might develop following vaccination is the indirect enzyme-linked immunosorbent assay (ELISA). We produced the recombinant spike protein used in this study. The optimization comprised adjusted concentrations of spike recombinant protein (5 and 10 ng/mL), blocking agent (2.5% and 5%), and conjugate (1:1000 and 1:5000). The optimal conditions in this study included a spiked concentration of 10 ng/mL, a blocking agent concentration of 5%, sample dilution of 1:33, and a conjugate concentration of 1:1000. The intra-assay value of this optimized indirect ELISA was 7.3, and the inter-assay value was 5.3. The commercial MyBioSource kit and immunodiagnostic were utilized as a reference in the T-test, with P-values of 0 and 0.313, indicating that the recombinant protein in-house ELISA kit in this study demonstrated the same ability as the commercial immunodiagnostic kit in detecting SARS-CoV-2 antibodies, allowing it to be used for post-vaccination efficacy evaluation.

Abstract

Melanoma is the deadliest type of skin cancer, having a high mortality rate. This cancer has an aggressive nature, is highly invasive, and has the tendency to metastasize. Matrix metalloproteinases (MMPs) are essential in that process, especially MMP2 and MMP9. Their expression is upregulated during metastasis progression. Myristicin is one example of a compound that can be utilized to target MMP 2 and MMP 9 in melanoma. This research concerns the activity of myristicin to inhibit melanoma cell invasion and migration by suppressing MMP2 and MMP9 gene expression. The MTT assay in this study demonstrated that myristicin exhibited strong cytotoxic activity against melanoma cells. This compound works in a dose-dependent manner by inhibiting cell migration and invasion. The invasion test was performed using the transwell assay, whereas the migration test was performed using the wound healing assay. The invasion assay results were consistent with MMP2 and MMP9 gene expression. These two genes were analyzed using the RT-qPCR technique. It has been demonstrated that low gene expression in melanoma cells inhibits cell invasion. In contrast, higher MMP2 and MMP9 gene expression was associated with an increase in the number of invasive cells on average. However, MMP2 and MMP9 in excessive expression and uncontrolled activity impair the ability of melanoma cells to form a monolayer sheet to cover wound gaps. This condition significantly reduced the migration rate and percentage of wound closure.

Abstract

Glyphosate, which has been documented as a contaminant in tea, promotes the proliferation of human breast cancer cells (MCF-7). Tea, on the other hand, includes various antioxidants, including epigallocatechin gallate (EGCG), which may protect against cancer cell proliferation. The purpose of this research is to determine the preventive effect of concentrated brewed green tea on MCF-7 development caused by glyphosate. The glyphosate concentration that promotes MCF-7 development was determined using a serial concentration of glyphosate. Glyphosate concentrations of up to 64 mg/L were shown to have no effect on MCF-7 cell proliferation. Concentrated brewed tea and EGCG 200 mg/L have the potential to suppress MCF-7 cell proliferation in the presence of glyphosate up to 512 mg/L. The combination of glyphosate and concentrated brewed tea or EGCG protects against glyphosate toxicity via altering the expression of tumor suppressor protein (p53).

Abstract

Three-dimensional (3D) culture is a technique commonly utilized in bioprocessing and biomedical research. Exosomes have been investigated as carriers for medications in numerous studies employing 3D culture methodologies. The objective of this research is to employ 3D cell culture for the isolation and treatment of exosomes targeting colon cancer cells. The isolation of exosomes obtained from HEK293 cells was conducted through the ultracentrifugation technique. Subsequently, exosome treatment was administered to WiDr cells at concentrations of 3.5 µg/ml, 7 µg/ml, and 14 µg/ml.The validation of molecular markers of exosomes (CD9 and CD81), along with BAX, BCL-2, and CD133, was performed using qRT-PCR. The findings revealed the successful isolation of exosomes derived from HEK293 cells, which exhibited the expression of markers CD9 and CD81. Furthermore, the expression of BAX and BCL-2 indicated the potential of exosomes to induce apoptosis, while the expression level of CD133 decreased with treatment at varying concentrations. These results suggest that exosome treatment has the capability to impede the proliferation of WiDr cells and reduce the expression of CD133, thereby signifying the potential application of exosomes as an in-vitro model for investigating cancer therapy in the future.

Abstract

Artificial whitening agents available in the market can cause damage to melanocytes; therefore, a safe and naturally derived skin-whitening agent is needed. Avocado seeds (Persea americana Mill.) are often discarded as waste but possess numerous health benefits. One of the compounds in avocado seeds is catechin, a flavonoid metabolite. This compound has been reported to exhibit antioxidant activity and inhibit tyrosinase to prevent melanin formation, making it suitable for skin-whitening applications. This study aimed to conduct phytochemical screening, assess antioxidant activity using the DPPH method, analyze catechin content using HPLC, and perform cell viability tests using the MTT method from the ethyl acetate extract of avocado seeds. Phytochemical screening has revealed the presence of flavonoids, saponins, and steroids. The DPPH assay yielded an IC50 value of 89.47±0.73 ppm, indicating an intense antioxidant activity, and HPLC detected 0.09% catechin. The MTT test results yielded cell viability percentages ranging from 80-100% at test concentrations of 0.75-25 ppm, with an IC50 value of 61.7 ppm. In conclusion, our results indicate that the ethyl acetate extract from avocado seeds affects cell viability without toxicity, warranting further testing for tyrosinase inhibition in the mouse melanoma B16F10 cell line.

Abstract

Black cumin (Nigella sativa) is a herbal plant that has been cultivated locally in Indonesia and is traditionally used for various diseases. Thymoquinone, one of the main components, is rich in biological activity. In several countries, topical application of its oil on human skin with vitiligo can stimulate skin repigmentation with minimal side effects. This study aims to determine the viability of B16F10 melanoma mouse cells against ethanol and n-hexane extracts of black cumin seeds through the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The ethanol extract (EE) yield was 14.306%, and the n-hexane extract (NHE) was 7.442%. Phytochemical screening of EE detected flavonoids, alkaloids, saponins, and steroids, and High-performance liquid chromatography (HPLC) detected 0.040% thymoquinone. The MTT test showed cell viability was >100% from EE at all treatment concentrations, namely 0.75-100 ppm and only 0.75-6.25 ppm for NHE. In conclusion, this study indicates that 96% EE of Nigella sativa is less toxic than NHE on B16F10 mouse melanoma cells and has potential as an alternative treatment for vitiligo, which needs to be proven in further research.
