Abstract

Epstein-Barr virus (EBV) is also called human herpes virus 4 (HHV-4), has detected 95% of the population and shows an asymptomatic state. EBV is etiological agent of oral hairy leukoplakia (OHL) in HIV patients. Latent membrane protein 1 (LMP1), an integral EBV protein can modulate growth, differentiation, induce the expression of several cells, activation of antigens, and adhesion molecules. The LMP1 gene has been associated with OHL. Objectives: to determine the prevalence of EBV in saliva and the LMP1 gene in HIV/AIDS patients with EBV positive. Methods: A cross-sectional was conducted on HIV/AIDS patients. The presence of EBV in saliva was done by mciroarray PCR. LMP1 is examined by using nested PCR. Results: The research subjects involved 30 HIV/AIDS patients consisting 70% men and 30% women, with 50 % age group of 31-40 years old and 40% had CD4 counts <200 cells/mm3 (40%). EBV in saliva was found in 26 out of 30 (87%) HIV patients and LMP1 was detected in 17 patients (65.38%). Conclusion: The high prevalence of EBV in saliva and the LMP1 gene may increase the risk of OHL. Early screening for EBV infection in patients with HIV/AIDS is important to reduce the risk of EBV-associated diseases.

Abstract

Mesenchymal stem cells (MSCs) are widely recognized in cell treatment due to their capacity to secrete trophic factors, differentiate multipotent, and self-renew. Although there is growing evidence that MSCs have therapeutic benefits in various clinical settings, these cells eventually lose their ability to regenerate as they age, which increases cellular dysfunction. Several factors may affect MSCs aging, such as culture dimensions, cryopreservation process, and long-term expansion. Traditional two-dimensional (2D) culture conditions lack the complexities required to recreate MSCs in their natural environment. Meanwhile, three-dimensional (3D) culture mimics the niche, dynamic, and specialized microenvironments of the cells in vivo. The most used storage technique for MSCs, cryopreservation, requires a very low temperature reduction, which stresses cells and can cause the release of pro-inflammatory cytokines. For the utilization of MSCs in therapeutic applications, an in vitro expansion technique is required. Repeated expansion may reduce proliferative capacity, disrupts cellular shape, and impairs the somatic cell function of MSCs. Various processes and techniques may influence MSCs leading to cell aging. One of the culture methods, 3D culture, is shown to reduce the factors that will compromise the therapeutic effects of MSCs, especially cell senescence. The effect of culture dimensions, cryopreservation, and long-term expansion on cell senescence will be discussed in this review article.Keywords: cell aging, mesenchymal stem cell, 3D culture, cell senescence, cryopreservation, long-term expansion

Abstract

Cedera ginjal akut atau Acute Kidney Injury (AKI) adalah salah satu sindrom klinis yang menyebabkan risiko mortalitas dan morbiditas yang tinggi. Deteksi dini AKI sangat diperlukan untuk mencegah kerusakan ginjal permanen dan memperlambat perkembangan AKI. Kidney Injury Molecule-1 (KIM-1) adalah biomarker yang sensitif, spesifik dan cepat dalam deteksi dini AKI. KIM-1 akan diekspresikan berlebih pada sel epitel tubulus proksimal setelah adanya cedera pada ginjal. KIM-1 dapat menggambarkan disfungsi ginjal melalui cairan tubuh, seperti plasma dan urin. Kajian pustaka ini membahas karakteristik, peran dan metode pengukuran KIM-1 sebagai biomarker untuk deteksi dini AKI. Kajian dilakukan terhadap 51 artikel yang didapat dari basis data PubMed dengan kata kunci “Kidney Injury Molecule-1”, “KIM-1 Biomarker”, “KIM-1 assay”, “Acute Kidney Injury” dan “KIM-1 kidney injury biomarker”. KIM-1 adalah glikoprotein transmembran tipe I dengan berat molekul ~104 kDa yang mengalami peningkatan konsentrasi di membran apikal sel epitel tubulus proksimal dan berperan dalam patogenesis cedera sel tubulus ginjal. KIM-1 memiliki sensitivitas dan spesifisitas yang baik dengan nilai AUC-ROC >0,5. Metode pengukuran yang paling banyak digunakan adalah ELISA dan sampel yang paling banyak digunakan adalah urin karena peningkatannya lebih jelas dibanding dengan plasma. KIM-1 urin yang diukur menggunakan metode ELISA memiliki potensi untuk dikembangkan dan digunakan sebagai parameter diagnosis dini AKI di masa mendatang

Abstract

Current anti-breast cancer drugs have limited efficacy and often cause severe side effects, highlighting the need for bioactive agents that could overcome these limitations. Curcumin, a phenolic compound from Curcuma domestica, has antineoplastic activity but has low solubility in physiological media, while moringa oil is a key component of the oil-phase nanocarrier and also possesses anticancer properties. The aim of this study was to develop a moringa oil-based nanocarrier system containing curcumin and to analyze its anticancer effects on MDA-MB-231 cell lines, focusing on the underlying mechanisms involving B-cell lymphoma 2 (Bcl-2) and Bcl-2-associated X (Bax) proteins. Additionally, the study investigated the side effects of the nanocarrier system following acute administration in animals. The anticancer effects were evaluated in vitro using MDA-MB-231 cell lines, while the acute toxicity assessment was conducted in healthy female Wistar rats. The nanocarrier system was formulated using moringa oil, Cremophor RH40, and PEG 400. Its cytotoxicity against MDA-MB-231 cells was assessed using the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay. DNA fragmentation, apoptosis, and the expression of Bax and Bcl-2 proteins were analyzed via terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assays, flow cytometry, and western blotting. Acute toxicity was further evaluated in female Wistar rats. The results demonstrated that the moringa oil-based nanocarrier system containing curcumin inhibited cell proliferation and induced apoptosis in MDA-MB-231 cells. Curcumin suppressed tumorigenesis by modulating Bcl-2 and Bax protein expression. Our data indicated that the combination of curcumin and moringa oil in a nanocarrier system had greater anticancer potential than either component alone. Moreover, administration of the nanocarrier system did not result in any clinically significant changes in body weight, behavior, or organ weight indicative of toxicological effects. No treatment-related histopathological abnormalities were observed at terminal necropsy. In conclusion, this novel combination of curcumin and moringa in nanocarrier system has better anticancer potential; nevertheless, further studies are needed to confirm this in cancer animal models.

Abstract

Spons laut merupakan salah satu sumber utama senyawa bioaktif karena kemampuannya menghasilkan metabolit dengan struktur unik, seperti manzamine A, avarol, dan callyaerin G, yang memiliki aktivitas biologis tinggi sebagai mekanisme pertahanan diri. Dua spesies spons laut yang dilaporkan memiliki potensi aktivitas biologis adalah Stylotella aurantium dan Callyspongia aerizusa, namun studi mengenai potensi sitotoksisitas dan antikanker keduanya masih terbatas. Penelitian ini bertujuan mengevaluasi potensi sitotoksisitas ekstrak metanol dan n-heksan dari S. aurantium dan C. aerizusa terhadap lini sel kanker serviks HeLa dengan menggunakan metode water soluble tetrazolium-8 (WST-8). Hasil uji menunjukkan bahwa ekstrak metanol S. aurantium memiliki aktivitas sitotoksik dengan nilai IC₅₀ sebesar 873.65 µg/mL pada waktu perlakuan 24 jam. Berdasarkan kriteria ISO 10993-5, ekstrak metanol S. aurantium pada konsentrasi 1.000 µg/mL dengan waktu perlakuan 24 jam menghasilkan persentase sel viabel sebesar 39,88 ± 2,88%, yang dikategorikan sebagai aktivitas sitotoksisitas moderat hingga kuat. Sebaliknya, ekstrak n-heksan S. aurantium serta ekstrak metanol dan n-heksan C. aerizusa menunjukkan nilai IC₅₀ >1.000 µg/mL pada waktu perlakuan 24 jam dan tidak menunjukkan aktivitas sitotoksisitas signifikan terhadap sel HeLa pada konsentrasi 1.000 µg/mL. Temuan ini mengindikasikan bahwa ekstrak metanol S. aurantium memiliki potensi sitotoksik yang layak diteliti lebih lanjut sebagai kandidat antikanker.

Abstract

Disobinol is a limonoid compound from the seeds of the Chisocheton macrophyllus plant that has been reported to have anticancer activity against cervical cancer cell lines. Cervical cancer is a type of cancer caused by infection with Human papillomavirus (HPV) types 16 and 18, leading to the transformation of normal cervical epithelial cells into cancerous cells. Previous studies show that Disobinol has a cytotoxic effect on HeLa cells with the IC50 value 52,92 μg/mL (24 hours’ incubation). This study aims to determine the level of apoptosis in HeLa cells treated with Disobinol and observe the DNA fragmentation in HeLa cells undergoing apoptosis. The HeLa cells were treated with Disobinol at concentrations of 26,5 μg/mL (1/2 IC50), 52,3 μg/mL (IC50), and 104,6 μg/mL (2x IC50) and incubated for 24 hours. The level of apoptosis was analyzed by using flow cytometry, and the DNA fragmentation pattern was analyzed by agarose gel electrophoresis. The results showed that Disobinol induces early apoptosis in HeLa cells, although the difference in the percentage of cell death is not very significant, which were 37.05%, 37.7%, and 41.60%, respectively. The DNA fragmentation pattern in HeLa cells treated with various concentrations of Disobinol was also observed on agarose gel. Therefore, Disobinol has the potential to be used as a chemotherapeutic drug or as a lead compound for the treatment of cervical cancer.
