These technologies provide an excellent opportunity to produce biomass and bioactive compounds from plants, especially Gynura procumbens. Previous reports mentioned a small-scale bioreactor could increase biomass and bioactive compounds of G. procumbens adventitious roots. Therefore, a larger bioreactor for adventitious root culture is necessary to develop. In this study, the development of the 19 L pilot bioreactor was successful. The optimal condition for bioreactor sterilization is 1.8 bar for 60 min using an autoclave. We found that G. procumbens adventitious roots culture in pilot bioreactors has resulted in optimal biomass using MS-Tek media (technical grade) compared to MS-PA (pro analyze) media after 35 d of the culture period. Although, higher productivity of total phenolics and total flavonoids in G. procumbens roots has been achieved from MS-PA media rather than MS-Tek media. In further study, it is necessary to evaluate the effect of technical-grade chemicals on kinetics root growth and chemical uptake. The hope is to obtain a suitable media formulation with affordable cost for adventitious root culture production.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47741451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Doxorubicin, for example, increases the level of reactive oxygen species (ROS), leading to cell senescence in the kidneys. Cardamom essential oil (Amomum compactum Soland. ex Maton) contains compounds that exhibit antioxidant activity, such as 1.8-cineole, α-pinene, α-terpineol, and linalool. This study focused on exploring the potency of cardamom essential oil (CEO) as an anti-senescence induced by doxorubicin using Vero cells. CEO was obtained by steam distillation. The cytotoxic assay was carried out using trypan blue exclusion assay. We performed the 2',7'-dichlorodihydrofluorescein diacetate (DCFDA) staining and the senescence-associated beta-galactosidase (SA-β-gal) staining to measure the effect of CEO on intracellular ROS level and cell senescence, respectively. Analysis of the compounds with gas chromatography-mass spectrophotometry (GC-MS), revealed seven compounds with significant abundance, namely 1.8-cineole (50.82%), ß-pinene (12.43%), α-terpineol (8.50%), fenchone (4.10%), α-pinene (4.00%), sabinene (3.00%), and linalool (1.98%). The cytotoxicity assay of CEO on Vero cells showed an IC50 value of 178 μg/mL. Thus, the CEO is considered to be not cytotoxic and safe for normal kidney cells. Concentrations of 50 and 100 μg/mL reduced the senescence induced by doxorubicin. Therefore, the CEO has the potency as a nephroprotective agent in doxorubicin-induced senescence.

The leaves of S. trifasciata show antibacterial properties against Pseudomonas aeruginosa. This bacterium is an opportunistic pathogen that can cause serious illness in humans and produce a variety of virulence factors responsible for bacterial pathogenesis with quorum sensing (QS) systems that mediate intracellular communication. Bacteria produce protease through a QS mechanism in which they express signaling molecules to become pathogens. Proteases are extracellular enzymes required for successful infection that mediate biofilm spread through QS and regulate a variety of cellular and physiological functions. This research aimed to evaluate the protease, and anti‐QS activities of the ethanolic extract from S. trifasciata leaves against P. aeruginosa and the expression of QS genes. An azocasein test was used to determine the protease activity in qualitative and quantitative methods. Using real‐time quantitative polymerase chain reaction, a study was conducted to investigate the effect of ethanolic extract from S. trifasciata leaves on selected QS‐regulatory genes at the transcriptional level. The results showed that the potential ethanolic extract from S. trifasciata leaves inhibited the protease enzyme activity by as much as 77.1%.

This study aims to determine the activity, purity level, and molecular weight of purified chitinase from Micromonospora sp. AR17 determines the concentration of NAG produced by purified chitinase that has been characterized. Chitinase was produced by fermentation in colloidal chitin broth at 40 °C, pH 7, for 7 days, while chitinase activity was checked every 24 h. The optimal fermentation time was used to produce chitinase for a further purification step. Enzyme purification was carried out by ultrafiltration, ammonium sulfate precipitation, ion exchange chromatography (Q Sepharose Fast Flow), and gel filtration (Sephacryl S‐300). The purified enzyme was then char‐ acterized for optimum time, pH, and temperature to produce NAG. The results suggested that the fourth day was the optimal time for chitinase production, with chitinase activity of 0.0040 U/mL and a NAG concentration of 7.62 µg/mL.

Thus, characterization of the virus strains from Indonesia is important. GISAID, NCBI BLAST, and MAFFT version 7 were used. There were 9,488 isolates in Indonesia as of November 2021, with the majority including the Delta variant. While most of the isolates have mutations common to those from other countries, there are some atypical ones, such as mutation V1264L in the Delta variant that was suspected to play a role in worsening the pandemic. The Delta variant had the most mutations in the spike protein when compared to the Alpha and Beta variants, giving it important roles in infectivity and vigorous entry into cells, with some general clinical manifestations like fever and sore throat; however, the severity of the Delta variant is attributable to its rapid growth.

IL‐10 and TGF‐β act as robust anti‐inflammatory cytokines in accelerating the wound healing process by regulating myofibroblasts. Hypoxic mesenchymal stem cell‐conditioned medium (hypMSC‐CM) containing cytokines potentially contribute to accelerate wound repair without scarring through the paracrine mechanism. This study aims to observe the role of hypMSC‐CM in controlling TGF‐β and IL‐10 levels to accelerate full‐thickness wound repair and regeneration. A total of 24 male Wistar rats were used in this study. Six healthy rats as a sham group and 18 rats were created as full‐thickness‐wound animal models using a 6 mm punch biopsy. The animals were randomly assigned into three groups (n = 6) consisting of two treatment groups treated with hypMSC‐CM at a low dose (200 µL hypMSC‐CM with 2 g water‐based gel added) and a high dose (400 µL hypMSC‐CM with 2 g water‐based gel added) and a control group (2 g water‐based gel only). The IL‐10 and TGF‐β levels were examined by ELISA. The results showed a significant increase in IL‐10 levels on day 3 after hypMSC‐CM treatment, followed by a decrease in platelet‐derived growth factor (PDGF) levels on days 6 and 9. In line with this finding, the TGF‐β levels also increased significantly on day 3 and then linearly decreased on days 6 and 9. HypMSC‐CM administra‐ tion may thus promote wound healing acceleration by controlling IL‐10 and TGF‐β levels in a full‐thickness‐wound rat model.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44183714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the chemical process often produces a by‐product that may be harmful to human health. Therefore, this study established a protocol to induce hairy roots (HRs) from a Vietnamese carrot variety and produce natural β‐carotene. The Rhizobium rhizogenes ATCC15834 harbouring Ri plasmid and a Vietnamese carrot variety were used as materials for genetic transformation and HR induction studies. The result showed that approximately 50 HR lines were obtained. Culture medium supplemented with 30 mg/L of sucrose that gave the highest biomass of HR was shown in carrot HR line 30, which had a doubling time of 6.5 days. The highest content of β‐carotene extraction, at 128 mg/100g hairy roots, was achieved with a ratio volume (v/v) of 2‐propanol and plant samples of 20:1, followed by two hours’ incubation with 2‐propanol at 60 °C. Our study reveals a highly efficient protocol for Vietnamese carrot hairy root establishment and multiplication. A very efficient protocol for β‐carotene extraction from the hairy root was established to produce natural β‐carotene that achieves the same β‐carotene quantity as that produced by normal roots. This study provides new insight into the production of high‐content and natural β‐carotene for therapeutic application.","PeriodicalId":13452,"journal":{"name":"Indonesian Journal of Biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45089616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to explain the anti‐diabetic effect of andrographolide compared to pioglitazone (a positive control) on glucose uptake by measuring the expression levels of peroxisome proliferator‐activated receptor gamma (PPARγ) and glucose transporter type 4 (GLUT‐4) genes in 3T3‐LI mouse adipocytes as an in vitro model. The differentiation of mature adipocytes from 3T3‐L1 fibroblasts was induced with 3‐isobutyl‐1‐methylxanthine, dexamethasone, and insulin. Andrographolide was provided through direct isolation from A. paniculata herbs. The gene expression was detected using the reverse transcription‐polymerase chain reaction (RT‐PCR). Pioglitazone and andrographolide significantly increased glucose uptake capability. Andrographolide was able to increase the mRNA levels of PPARγ and GLUT‐4 compared to pioglitazone with the best concentration at 5.6 µM. In conclusion, andrographolide can improve glucose uptake by increasing mRNA levels of PPARγ and GLUT‐4 that encodes protein, which are key factors for glucose homeostasis.
