Abstract

Mesenchymal stem cells (MSC) derived from white adipose tissue are considered to be an appropriate therapeutic candidate for various human diseases due to their natural ability to maintain homeostasis. They have also been considered for use as a therapeutic alternative due to their sufficient availability and ease of harvesting. MSC play an important role in the process of adipogenesis and energy metabolism that is directly related to the pathogenesis of various degenerative diseases and metabolic syndromes. The purpose of this study was to obtain MSC cultures from white adipose tissue biopsied from three adult males Macaca fascicularis and to evaluate these cultures qualitatively and quantitatively regarding their characteristics and ability to differentiate. Polymerase chain reaction (PCR) was used to confirm the expression of mesenchymal stem cell-specific gene markers, and a specific growth medium was used to differentiate these cells into adipocytes, chondrocytes, and osteocytes. The results obtained showed that the MSC culture from M. fascicularis WAT had a fibroblast-like morphology with a spindle shape. The MSC markers of CD73, CD90 and CD105, were also expressed. The MSC culture was also able to differentiate into adipocytes, chondrocytes, and osteocytes. Based on these results, white adipose tissue from Macaca fascicularis was found to have potential as a source of MSC.

Abstract

Pemanfaatan hewan primata dalam hal ini monyet ekor panjang (MEP) atau Macaca fascicularis sebagai hewan model untuk uji vaksin Human Papilloma Virus (HPV) harus melalui penapisan untuk mendapatkan hewan yang tepat. Tujuan dari penelitian ini untuk menapis dan memvalidasi kecocokan MEP sebagai hewan model vaksin papillomavirus. Jenis vaksin yang akan di uji menentukan jenis penapisan yang dilakukan. Metode penapisan dilakukan dengan uji serologis, molecular dan patologi serta validasi dengan histopatologi. Vaksin pencegahan atau profilaksis memerlukan hewan yang bebas dari virus-virus penekan kekebalan tubuh (immunosuppressive virus) dan HPV nya sendiri agar antibodi yang terbentuk benar-benar berasal dari vaksin yang diujikan, vaksin terapeutik memilih hewan dengan positif MfPV khususnya MfPV3. Hasil penapisan dari 136 ekor hewan diperoleh 42 (30%) ekor hewan dengan negatif antibodi serta  diperoleh  39 (28%) ekor MEP positif MfPV diantaranya yaitu sebanyak 24 (17%) ekor positif MfPV-3. Hewan dengan positif MfPV3 selanjutnya akan digunakan untuk uji vaksin terapeutik HPV. Adanya perubahan abnormal sel-sel epitel serviks pada hewan dengan positif MfPV yang menuju pada pembentukkan sel kanker (Carcinoma Intra epithelial Neoplasia/CIN) juga semakin menguatkan kemiripan model MEP dengan manusia.

Abstract

Macaca nemestrina, also known as the pigtail macaque, plays a crucial role in drug development and serves as a highly valuable animal model for studying various human diseases due to its phenotypic similarities to humans, including those related to the aging process. Hematology is a critical component of clinical assessments for this spesies, serving both as a diagnostic tool to determine their health status and to characterize disease models, including degenerative and geriatric diseases. As anemia is a common phenomenon in the elderly, it is also important to determine whether M. nemestrina exhibit a similar condition with age. The aim of this study was to determine the hematological profiles of clinically healthy female M. nemestrina across young, adult, and elderly age groups, particularly related to anemia parameters. This study was conducted at the Primate Research Center, IPB University, Bogor, Indonesia. The animals were part of a breeding colony and were divided into three groups based on age: young (5–7 years), adult (12–14 years), and elderly (18–21 years). Following anesthesia with ketamine, a physical examination was performed to determine clinical status, and blood samples were collected for a complete blood count (CBC) evaluation using an automated analyzer. The results showed that total erythrocytes, hemoglobin concentration, hematocrit value, and mean corpuscular hemoglobin (MCH) were significantly different (P<0.05) in the elderly group compared to the other groups. Additionally, the red cell distribution width (RDW) percentage and leukocyte count differed significantly between the adult and elderly groups. The results showed that the erythrogram differs with age in clinically healthy M. nemestrina, suggesting the importance of determining appropriate baseline reference values in macaques of different ages.

Abstract

High-risk human papillomaviruses (HPVs) are the primary etiological agents of cervical cancer, accounting for more than 300,000 deaths annually worldwide. Current prophylactic vaccines based on recombinant L1 major capsid virus-like particles (VLPs) have demonstrated strong efficacy but are restricted to a limited spectrum of HPV types. To address this limitation, the present study evaluated a recombinant L1L2 chimeric protein derived from HPV type 52 as a potential candidate for a broad-spectrum vaccine. The chimeric protein was expressed in Escherichia coli strain BL21 (DE3) and purified for immunization studies. Female BALB/c mice (Mus musculus, n = 5 groups) were immunized, and immune responses were analyzed by enzyme-linked immunosorbent assay (ELISA) and pseudovirion-based neutralization assays (PBNA). The recombinant L1L2 vaccine candidate induced detectable antibody responses against HPV antigens; however, neutralizing activity remained modest. Histopathological analysis of liver and kidney tissues showed no evidence of toxicity, supporting the safety profile of the candidate. In summary, these results suggest that the HPV type 52 L1L2 chimeric protein represents a promising platform for the development of cervical cancer vaccines, although further optimization is required to achieve robust cross-neutralizing efficacy.

Abstract

Indonesian people use plants as medicine because they are considered to have fewer side effects. The Lingga island community used Phanera semibifida (Roxb.) traditionally to make therapeutic drugs. P. semibifida has the potential to be a medicinal plant. We extracted stems and leaves with three different solvents and tested their cytotoxic activity. The ethanolic stem extract showed the highest value of LC₅₀ in the moderate toxicity category. The ethanolic steam extract continued to be subjected to in silico analysis, using molecular docking. We selected four compounds for molecular docking studies against five cancer-related proteins. The proteins are Estrogen receptor α, CDK2, Human Cytochrome P450 CYP17A1, Cyclin A, and BCL-2. The result showed that Ellagic acid bound strongly to Estrogen receptor α, CDK2, CYP17A1, and Cyclin A protein. Cyanidanol showed the highest affinity to BCL-2. These results suggest that P. semibifida contains compounds that can target multiple cancer-related proteins. Our findings highlight its potential as a source of anticancer agents. We recommend isolating these compounds and testing their efficacy through in vitro and in vivo studies to confirm their therapeutic potential in future studies.

Abstract

Colistin is the last drug of choice for dealing with carbapenem-resistant Enterobacteriaceae bacteria; hence, this drug is very crucial to human health. The discovery of a plasmid-mediated colistin-resistant gene, the mobilized colistin resistance-1 (mcr-1), signals a significant global health threat. Colistin sulfate is an antimicrobial agent which has been approved for use in broilers in Indonesia. Thus, this study aimed to measure the prevalence of colistin-resistant Escherichia coli and to detect the mcr-1 colistin-resistant gene in E. coli and E. coli O157:H7 in the entire supply chain of broilers in Bogor Regency, West Java Province, Indonesia. Samples were taken from 47 flocks that used colistin sulfate (47 pools of cloacal swabs, 47 pools of drinking water, and 47 pools of litter), seventy fresh meat samples and seven plucker swab samples from seven small-scale poultry slaughterhouses, seventy fresh meat samples from seven traditional markets, and seventy cooked meat samples from seven small restaurants. The isolation of E. coli was done on each of the 358 samples, and 493 isolates were obtained. All the E. coli isolates were then tested for their susceptibility to colistin sulfate by using the agar dilution method. The detection of the mcr-1 gene from the colistin-resistant isolates (minimum inhibitory concentration > 2 µg/mL) was conducted using the polymerase chain reaction (PCR). The prevalence value of colistin-resistant E. coli in all the isolates was 11.76% (CI 95%; CL 9.21–14.91), and the prevalence of the mcr-1 gene was 10.55% (CI 95%; CL 8.13–13.57%). A very good agreement correlation existed between the colistin-resistant phenotype and the mcr-1 gene (κ = 0.939). The mcr-1 gene was found in 89.66% of colistin-resistant E. coli isolates. Two colistin-resistant and mcr-1 carrying isolates were identified as E. coli O157:H7 serotype. This research was the first study attempt on the mcr-1 gene in Indonesia, covering the entire supply chain of broiler meat from farms to consumers. The results indicated the necessity to reduce the use of colistin sulfate in broiler management and to improve biosecurity measures, not only in farms but also in the entire supply chain of broiler meat production.

Abstract. Elfita L, Wientarsih I, Sajuthi D, Bachtiar I, Darusman HS. 2020. The diversity in nutritional profile of farmed edible bird’s nests from several regions in Indonesia. Biodiversitas 21: 2362-2368. &nbsp;Edible bird’s nest (EBN) is produced by certain swiftlet species mainly Aerodramus fuciphagus. This study aimed to compare the composition of proximate, nitrite, nitrate, amino acid and protein profiles of EBNs collected from different regions in Indonesia (West Sumatra, South Sumatra, West Java, West Kalimantan, Central Sulawesi, and Southeast Sulawesi). The results showed that the order of proximate composition was protein (53.09-56.25%) &gt; carbohydrate (19.57-23.04%) &gt; moisture (17.08-21.50%) &gt; ash (5.44-6.25%) &gt; fat (0.07-0.57%). Nitrite and nitrate contents were 3.11-18.28 ppm and 650.11-1051.06 ppm, respectively. Amino acid analysis found that EBNs contained 18 amino acids, composed of ten essential amino acids and eight non-essential amino acids. Aspartic acid content of EBNs from West Sumatra and West Kalimantan (4.21 and 3.27%, respectively) were much higher than the one found in other regions, which was on the range of 0.32-0.37%. SDS-PAGE analysis demonstrated that majority of EBNs possessed seven protein bands with molecular weight range of 19.6 to 82.7 kDa. However, EBNs from West Sumatra and West Kalimantan showed abundant of protein with molecular weight of approximately 34.0 kDa. Thus, EBNs collected from different regions in Indonesia showed different nutritional profiles.

Abstract. Ramadhanty PW, Saepuloh U, Suparto IH, Darusman HS. 2023. Characterization of 16S rRNA of the gut microbiome in long-tailed macaque (Macaca fascicularis) with spontaneous type 2 diabetes mellitus. Biodiversitas 24: 6191-6199. The gut microbiota in the body is very complex and varied. It is known to influence human health. Imbalance (dysbiosis) of the gut microbiota can lead to type 2 diabetes mellitus (T2DM) and become a new feature in the development of the disease. Several human studies have compared the bacterial community in T2DM and non-T2DM patients. Until now, research on gut microbiota associated with T2DM in non-human primate animal models is still rare. T2DM can be developed by long-tailed macaque with clinical features similar to humans, which provides important information about the relationship between gut microbiota and T2DM. This study aims to characterize full-length 16S rRNA genes to obtain gut microbiota profiles in long-tailed macaques with and without spontaneous T2DM. The characterization was carried out using a metagenomic approach targeted at the full-length 16S rRNA gene with Nanopore technology (GridION) as one of the third-generation sequencing. The sample used was rectal swabs from adult male long-tailed macaques in the spontaneous T2DM group (n=3) and non-T2DM group (n=3). An increase in the alpha diversity, Firmicutes phylum, Oscillibacter genus, Oscillibacter valericigenes, and Oscillibacter ruminantium species, as well as a decrease in the Proteobacteria phylum were found in the T2DM group. The Firmicutes/Bacteroidetes ratio was also increased in the T2DM group compared to the non-T2DM group, which indicates dysbiosis. Based on these results, the metagenomic marker of the gut microbiome T2DM was obtained in long-tailed macaque primates, similar to humans with T2DM.
