Abstract
The safest and most effective sources of medications are natural and traditional medicines derived from plants and herbs. In Western India, various parts of the Dalbergia sissoo plant, which belongs to the Fabaceae family, have been traditionally used to treat different types of cancer by the local tribes. However, this claim has not been scientifically proven yet. Thus, the purpose of this study was to examine the antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity) and anticancer effects of different plant extracts from Dalbergia sissoo bark, root, and branch on six different cancer cell lines (K562, PC3, A431, A549, NCIH 460, and HEK 293 T) using in vitro cell viability and cytotoxicity assays. The study also involved in silico docking, MD simulation, and ADME studies of previously reported bioactive compounds from the same parts of the plant to confirm their bioactivity. The DPPH radical scavenging experiment findings showed that the methanol: water extract of the bark had a more significant antioxidant activity IC50 (45.63 ± 1.24 mg/mL). Furthermore, the extract prevented the growth of the A431, A549, and NCIH 460 cancer cell lines with the lowest IC50 values of 15.37, 29.09, and 17.02 g/mL, respectively, demonstrating remarkable anticancer potential. Molecular docking and dynamic simulation studies revealed that Prunetin, Tectorigenin, and Prunetin 4'-O-Galactoside show efficient binding to the EGFR binding domain. This study suggests that tested hits may have antioxidant and anticancer agents and can be considered for future applications in the pharma sector.Communicated by Ramaswamy H. Sarma.

Abstract
Programmed cell death-ligand 1 (PDL1) is a transmembrane protein that is characterized as an immune regulatory molecule. We recently developed a recombinant single-chain fragment of variable domain (scFv) against PDL1, which showed high binding efficiency to purified recombinant PDL1 protein. However, at that time, proof-of-concept data for the effect of scFv using PDL1-expressing cells was lacking. In this study, we conducted two kinds of cell-based immunoassays, western blotting and enzyme-linked immunosorbent assay, using anti-PDL1 scFv. The results indicate that scFv can selectively and sensitively detect PDL1 from PDL1 positive human cancer cell lines. Our findings suggest that scFv could be used as a potential PDL1 inhibitor agent and probe for cell-based immunoassays to detect PDL1.

Abstract
Giant plasma membrane vesicles (GPMVs) have been utilized as a model to study phase separation in the plasma membrane. Additionally, GPMVs have been employed as vehicle for delivering molecular cargo, including small molecule drugs and nanoparticles. Nearly all examples of GPMV production use a defined salt buffer that is a stark contrast to typical cell culture medium. In this study, we demonstrate that the addition of formaldehyde and dithiothreitol to a standard culture medium was capable of generating GPMVs at a concentration equal to or higher than the traditional production buffer. These methods were evaluated for two human cell lines: kidney endothelial and Schwann cells (SCs). Morphological properties of the resultant GPMVs exhibited no significant differences between the two formulations. Factors such as pH and seeding density significantly influenced the production of GPMVs in both mediums. The cell type and seeding density was shown to influence the number of GPMVs to the greatest extent. SCs yield more GPMVs at higher seeding densities compared to endothelial cells. Stability of the membrane of the GPMVs produced in both mediums was evaluated by monitoring passive diffusion of two fluorescently tagged dextrans (3 and 10 kDa). Regardless of the production formulation or cell type, approximately 85% GPMVs are impermeable to either dextran. Cold storage for on-demand use and shipping are essential for broader use of GPMVs. Toward this aim, we have evaluated the GMPV number and morphologies following storage at -80 °C and in liquid nitrogen. A significant loss of the GPMV number, ∼30%, was observed following storage across production formulations as well as cell types. Our results indicate that smaller GMPVs, <5 μm are more stable for preservation. In conclusion, GPMVs can be produced in a broad range of formulations, exhibit a high degree of stability, and can undergo cold storage for further adoption.

Abstract
Tissue engineering is currently one of the fastest-growing areas of engineering, requiring the fabrication of advanced and multifunctional materials that can be used as scaffolds or dressings for tissue regeneration. In this work, we report a bilayer material prepared by electrospinning a hybrid material of poly(vinyl alcohol) (PVA) and bacterial cellulose (BC NFs) (top layer) over a highly interconnected porous 3D gelatin-PVA hydrogel obtained by a freeze-drying process (bottom layer). The techniques were combined to produce an advanced material with synergistic effects on the physical and biological properties of the two materials. The bilayer material was characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and a water contact measurement system (WCMS). Studies on swelling, degradability, porosity, drug release, cellular and antibacterial activities were performed using standardized procedures and assays. FTIR confirmed cross-linking of both the top and bottom layers, and SEM showed porous structure for the bottom layer, random deposition of NFs on the surface, and aligned NFs in the cross section. The water contact angle (WCA) showed a hydrophilic surface for the bilayer material. Swelling analysis showed high swelling, and degradation analysis showed good stability. The bilayer material released Ag-sulfadiazine in a sustained and controlled manner and showed good antibacterial activities against severe disease-causing gram + ive and -ive (Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa) bacterial strains. In vitro biological studies were performed on fibroblasts (3T3) and human embryonic kidneys (HEK-293), which showed desirable cell viability, proliferation, and adhesion to the bilayer. Thus, the synergistic effect of NFs and the hydrogel resulted in a potential wound dressing material for wound healing and soft tissue engineering.

Abstract
Familial Mediterranean Fever (FMF) is a recurrent polyserositis characterized by self-limiting episodes or attacks of fever along with serosal inflammation. It mainly impacts people of the Mediterranean and Middle Eastern basin. FMF is a recessive autoinflammatory condition caused by mutation in the MEFV gene located on chromosome 16p13. MEFV mutations lead to the activation of the pyrin inflammasome resulting in an uncontrolled release of IL-1β. Various in vitro, in vivo and ex vivo experimental models have been developed to further comprehend the etiology and pathogenesis of FMF. These models have been proven to be clinically relevant to human FMF and can provide significant information about biological systems with respect to this condition. Additionally, these models have provided pertinent contributions to the development of potent therapeutic strategies against FMF. In this review, we describe the different experimental models utilized in FMF and we focus primarily on the most widely used models that have produced prominent insights into the pathophysiology of the disease.

Ameliorative effect of traditional polyherbal formulation on TNF-α, IL-1β and Caspase-3 expression in kidneys of wistar rats against sodium fluoride induced oxidative stress. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116900. [PMID: 37442489 DOI: 10.1016/j.jep.2023.116900] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 07/05/2023] [Accepted: 07/08/2023] [Indexed: 07/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sharbat-e-bazoori Motadil (SBM) is a polyherbal formulation that have been used for centuries as a part of the Unani system of medicine for renal disease. AIM OF THE STUDY The objective of this study was to explore and validate the nephroprotective potential of sugar-free SBM (SF-SBM) and its mechanisms of action against sodium fluoride (NaF)-induced nephrotoxicity in HEK-293 cells. Additionally, the study aimed to assess the quality control of SF-SBM and investigate its effects using an in vivo rat model with pattern recognition following oral administration of SF-SBM. MATERIALS AND METHODS The nephroprotective effect of SF-SBM was investigated using both an HEK-293 cell line and Wistar rats. Nephrotoxicity was induced in these models by administering NaF at a concentration of 600 ppm (parts per million) for a duration of seven days. The SF-SBM formulation was standardized using high-performance thin-layer chromatography (HPTLC) to assess the presence of marker compounds, namely gallic acid, quercetin, and ferulic acid. Metabolite characterization of SF-SBM was carried out using ultra-high-performance liquid chromatography mass spectrometry (UPLC-MS) with a monolithic capillary silica-based C18 column. This analytical technique allowed for the identification of bioactive substances and verification of the identified markers. Acute toxicity of SF-SBM was evaluated in Wistar rats by administering a single oral dose of 2000 mg/kg of SF-SBM. The nephroprotective efficacy of SF-SBM was further assessed at low (LD), medium (MD) and high (HD) doses of 32.1, 64.2, and 128.4 mg/kg, respectively, administered orally. Nephrotoxicity was induced in Wistar rats by adding NaF to their drinking water for seven days. Biochemical and urine markers were analyzed to evaluate the antioxidant, inflammatory, and apoptotic potential of SF-SBM. Additionally, histopathological analysis and immunohistochemical alterations in the expression of caspase-3 and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-4 (NOX-4) in kidney tissue were performed to confirm the findings of the in vivo experiments. Furthermore, in vivo pattern recognition of SF-SBM metabolites, identified through GC-MS metabolomics, and in-silico docking analysis of major metabolites in plasma were conducted to gain further insights. RESULT Phytochemical analysis using HPTLC, TLC-bioautography, and UPLC-MS revealed the presence of several bioactive constituents in SF-SBM, including ferulic acid, gallic acid (GA), ellagic acid, quercetin, and apigenin. These compounds exhibit diverse pharmacological properties. In vitro studies demonstrated the protective effect of SF-SBM on HEK-293 cell line against nephrotoxicity. The acute toxicity study of SF-SBM at a dose of 2000 mg/kg showed no mortality or signs of toxicity throughout the 14-day observation period. In the in vivo studies, administration of NaF resulted in significant elevation (P < 0.001) of biochemical and urine parameters, indicating oxidative, inflammatory, and apoptotic stress. Histopathological examination revealed severe depletion of Bowman's capsule, and immunohistochemistry demonstrated negative immunostaining for caspase-3 and reduced NOX-4 reactions. Pre-treatment with SF-SBM significantly attenuated the elevated biochemical and urine markers, restored the antioxidant enzyme levels (such as SOD, CAT, GSH, GPx and NO), and regulated the expression of inflammatory cytokines (TNF-α, IL-1β, CASP-3) in kidney tissue at doses of SF-SBM-MD (64.2 mg/kg) and SF-SBM-HD (128.4 mg/kg), showing comparable results to those of α-Ketoanalogue. Histopathological assessment demonstrated improvements in tissue damage. Pattern recognition analysis of SF-SBM identified the presence of 56 metabolites at different time intervals. Additionally, in-silico studies revealed strong interactions of SF-SBM with a binding energy of -6.5 and -5.6 kcal for 4C2N. CONCLUSION The phytoconstituents present in SF-SBM play a crucial role in its nephroprotective action by acting as potent antioxidants and reducing proinflammatory and apoptotic damage in rat cells. This indicates that SF-SBM has promising potential for the treatment of nephrotoxicity.

Abstract
Astaxanthin is a fascinating molecule with powerful antioxidant activity, synthesized exclusively by specific microorganisms and higher plants. To expand astaxanthin production, numerous studies have employed metabolic engineering to introduce and optimize astaxanthin biosynthetic pathways in microorganisms and plant hosts. Here, we report the metabolic engineering of animal cells in vitro to biosynthesize astaxanthin. This was accomplished through a two-step study to introduce the entire astaxanthin pathway into human embryonic kidney cells (HEK293T). First, we introduced the astaxanthin biosynthesis sub-pathway (Ast subp) using several genes encoding β-carotene ketolase and β-carotene hydroxylase enzymes to synthesize astaxanthin directly from β-carotene. Next, we introduced a β-carotene biosynthesis sub-pathway (β-Car subp) with selected genes involved in Ast subp to synthesize astaxanthin from geranylgeranyl diphosphate (GGPP). As a result, we unprecedentedly enabled HEK293T cells to biosynthesize free astaxanthin from GGPP with a concentration of 41.86 µg/g dry weight (DW), which represented 66.19% of the total ketocarotenoids (63.24 µg/g DW). Through optimization steps using critical factors in the astaxanthin biosynthetic process, a remarkable 4.14-fold increase in total ketocarotenoids (262.10 µg/g DW) was achieved, with astaxanthin constituting over 88.82%. This pioneering study holds significant implications for transgenic animals, potentially revolutionizing the global demand for astaxanthin, particularly within the aquaculture sector.

Abstract
Esculetin is an antioxidant and anti-inflammatory compound derived from coumarin. Oxidative stress can cause overproduction of reactive oxygen species (ROS), which can lead to the development of chronic kidney failure. In this study, human embryonic kidney 293 (HEK293) cells were treated with tert-butyl hydroperoxide (t-BHP) to determine the antioxidant effects of esculetin. HEK293 cells were treated with t-BHP to validate changes in cell viability, ROS production, and apoptosis, and then treated with esculetin to evaluate the changes. Changes in mRNA and protein levels were analyzed using a proteome kit, PCR, and Western blotting. Esculetin improved HEK293 cell viability and reduced apoptosis caused by t-BHP-induced oxidative stress. At the mRNA and protein levels, esculetin decreased pro-apoptotic factor expression as well as increased anti-apoptotic factor expression. The antioxidant efficacy of esculetin was validated when it inhibited the apoptosis caused by t-BHP-induced oxidative stress in HEK293 cells.

Abstract
The kidneys are often involved in adverse effects and toxicity caused by exposure to foreign compounds, chemicals, and drugs. Early predictions of these influences are essential to facilitate new, safe drugs to enter the market. However, in current drug treatments, drug-induced nephrotoxicity accounts for 1/4 of reported serious adverse reactions, and 1/3 of them are attributable to antibiotics. Drug-induced nephrotoxicity is driven by multiple mechanisms, including altered glomerular hemodynamics, renal tubular cytotoxicity, inflammation, crystal nephropathy, and thrombotic microangiopathy. Although the functional proteins expressed by renal tubules that mediate drug sensitivity are well known, current in vitro 2D cell models do not faithfully replicate the morphology and intact renal tubule function, and therefore, they do not replicate in vivo nephrotoxicity. The kidney is delicate and complex, consisting of a filter unit and a tubular part, which together contain more than 20 different cell types. The tubular epithelium is highly polarized, and maintaining cellular polarity is essential for the optimal function and response to environmental signals. Cell polarity depends on the communication between cells, including paracrine and autocrine signals, as well as biomechanical and chemotaxis processes. These processes affect kidney cell proliferation, migration, and differentiation. For drug disposal research, the microenvironment is essential for predicting toxic reactions. This article reviews the mechanism of drug-induced kidney injury, the types of nephrotoxicity models (in vivo and in vitro models), and the research progress related to drug-induced nephrotoxicity in three-dimensional (3D) cellular culture models.

Protein arginine N-methyltransferase 5 in colorectal carcinoma: Insights into mechanisms of pathogenesis and therapeutic strategies. Biomed Pharmacother 2021; 145:112368. [PMID: 34794114 DOI: 10.1016/j.biopha.2021.112368] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 10/20/2021] [Accepted: 10/20/2021] [Indexed: 12/14/2022] Open
Abstract
Protein arginine N-methyltransferase 5 (PRMT5) enzyme is one of the eight canonical PRMTs, classified as a type II PRMT, induces arginine monomethylation and symmetric dimethylation. PRMT5 is known to be overexpressed in multiple cancer types, including colorectal cancer (CRC), where its overexpression is associated with poor survival. Recent studies have shown that upregulation of PRMT5 induces tumor growth and metastasis in CRC. Moreover, various novel PRMT5 inhibitors tested on CRC cell lines showed promising anticancer effects. Also, it was suggested that PRMT5 could be a valid biomarker for CRC diagnosis and prognosis. Hence, a deeper understanding of PRMT5-mediated CRC carcinogenesis could provide new avenues towards developing a targeted therapy. In this study, we started with in silico analysis correlating PRMT5 expression in CRC patients as a prelude to further our investigation of its role in CRC. We then carried out a comprehensive review of the scientific literature that dealt with the role(s) of PRMT5 in CRC pathogenesis, diagnosis, and prognosis. Also, we have summarized key findings from in vitro research using various therapeutic agents and strategies directly targeting PRMT5 or disrupting its function. In conclusion, PRMT5 seems to play a significant role in the pathogenesis of CRC; therefore, its prognostic and therapeutic potential merits further investigation.

Ultrastructural Features of Gold Nanoparticles Interaction with HepG2 and HEK293 Cells in Monolayer and Spheroids. NANOMATERIALS 2020; 10:nano10102040. [PMID: 33081137 PMCID: PMC7650816 DOI: 10.3390/nano10102040] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 10/13/2020] [Accepted: 10/13/2020] [Indexed: 12/14/2022]
Abstract
Use of multicellular spheroids in studies of nanoparticles (NPs) has increased in the last decade, however details of NPs interaction with spheroids are poorly known. We synthesized AuNPs (12.0 ± 0.1 nm in diameter, transmission electron microscopy (TEM data) and covered them with bovine serum albumin (BSA) and polyethyleneimine (PEI). Values of hydrodynamic diameter were 17.4 ± 0.4; 35.9 ± 0.5 and ±125.9 ± 2.8 nm for AuNPs, AuBSA-NPs and AuPEI-NPs, and Z-potential (net charge) values were −33.6 ± 2.0; −35.7 ± 1.8 and 39.9 ± 1.3 mV, respectively. Spheroids of human hepatocarcinoma (HepG2) and human embryo kidney (HEK293) cells (Corning ® spheroid microplates CLS4515-5EA), and monolayers of these cell lines were incubated with all NPs for 15 min–4 h, and fixed in 4% paraformaldehyde solution. Samples were examined using transmission and scanning electron microscopy. HepG2 and HEK2893 spheroids showed tissue-specific features and contacted with culture medium by basal plasma membrane of the cells. HepG2 cells both in monolayer and spheroids did not uptake of the AuNPs, while AuBSA-NPs and AuPEI-NPs readily penetrated these cells. All studied NPs penetrated HEK293 cells in both monolayer and spheroids. Thus, two different cell cultures maintained a type of the interaction with NPs in monolayer and spheroid forms, which not depended on NPs Z-potential and size.

Cytotechnology 2020; 72:731-739. [PMID: 32779071 DOI: 10.1007/s10616-020-00415-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Accepted: 08/04/2020] [Indexed: 11/28/2022] Open
Abstract
White-spotted charr (Salvelinus leucomaenis, S. I.) is an anadromous cold water-adapted fish, distributed in the Far East. We have previously reported the complete mitochondrial DNA sequences of white-spotted chars (S. l. imbrius and S. l. pluvius) in Japan. In general, fish hepatocytes are useful for cellular and biochemical studies of fish. In this study, we isolated hepatocytes from the liver of white-spotted charr and used basic methods, such as enzyme digestion and low centrifugation, to analyze the molecular mechanisms involved in specific cellular responses. The isolated hepatocytes could be cultured at 5-20 °C but not 37 °C. The morphology of hepatocytes was altered in a temperature-dependent manner. The properties of hepatocyte were similar to those of living fish. Moreover, the proliferation rate and damage of isolated hepatocytes depended on the concentration of fetal bovine serum in the culture medium. Taken together, this study demonstrates that this simple method for isolation and culture of hepatocytes from white-spotted charr may be useful for other biochemical and cellular studies.
