Semenova MN, Kuptsova TS, Semenov VV. Toxicity of organic solvents and surfactants to the sea urchin embryos. CHEMOSPHERE 2024; 353:141589. [PMID: 38432465 DOI: 10.1016/j.chemosphere.2024.141589] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 02/25/2024] [Accepted: 02/29/2024] [Indexed: 03/05/2024]
Abstract
A comparative toxicity of widely applied organic solvents (methanol, ethanol, n-propanol, i-propanol, n-butanol, 2-butanol, i-butanol, t-butanol, 3-methoxy-3-methylbutanol-1 (MMB), ethylene glycol, diethylene glycol, 2-methoxyethanol, 2-ethoxyethanol, glycerol, ethyl acetate, acetonitrile, benzene, dioxane, dimethylformamide, dimethylacetamide, dimethylsulfoxide, 2-pyrrolidone, and N-methyl-2-pyrrolidone) and surfactants (PEG 300, PEG 6000, Tween 20, Tween 80, miramistin, and Cremophor EL) was studied using a sea urchin embryo model. Sea urchin embryo morphological alterations caused by the tested chemicals were described. The tested molecules affected P. lividus embryo development in a concentration-dependent manner. The observed phenotypic anomalies ranged from developmental delay and retardation of plutei growth to formation of aberrant blastules and gastrules, cleavage alteration/arrest, and embryo mortality. Discernible morphological defects were found after embryo exposure with common pharmaceutical ingredients, such as glycerol, Tween 80, and Cremophor EL. In general, solvents were less toxic than surfactants. PEG 6000 PEG 300, DMSO, ethanol, and methanol were identified as the most tolerable compounds with minimum effective concentration (MEC) values of 3.0-7.92 mg/mL. Previously reported MEC value of Pluronic F127 (4.0 mg/mL) fell within the same concentration range. Toxic effects of methanol, ethanol, DMSO, 2-methoxyethanol, 2-ethoxyethanol, Tween 20, and Tween 80 on P. lividus embryos correlated well with their toxicity obtained using other cell and animal models. The sea urchin embryos could be considered as an appropriate test system for toxicity assessment of solvents and surfactants for their further application as solubilizers of hydrophobic molecules in conventional in vitro cell-based assays and in vivo mammalian models. Nevertheless, to avoid adverse effect of a solubilizing agent in ecotoxicological and biological experiments, the preliminary assessment of its toxicity on a chosen test model would be beneficial.

Biomed Pharmacother 2024; 172:116216.

Abstract
Platycodin D (PD) is the main component of triterpene saponins found in Platycodi radix. In this study, we observed a decrease in cell viability, an increase in apoptotic bodies, and an increase in the rate of apoptosis. Also, we observed an increase in cleaved PARP and Bax, a decrease in Bcl-2, and p-ERK, and an increase in p-p38 and p-JNK. Furthermore, a change in cell viability and the expression of p-p38, Bax, and Bcl-2 using the p38 inhibitor revealed a decrease in p-p38 and Bax and an increase in Bcl-2 in the inhibitor treatment group. In addition, we observed an increase in vacuole formation through morphological changes and an increase in acidic vesicular organelles (AVOs). We also observed an increase in the expression of beclin 1, LC 3-I, and -II. There was no significant decrease in cell viability in the group treated with 3-MA, but a decrease in cell viability was noted in the group treated with HCQ. HCQ treatment resulted in an increase in Bax and a decrease in Bcl-2. These findings reveal that in HT-29 colon cancer cells, PD induces apoptosis through the MAPK pathway, thereby exerting anticancer effects. Moreover, autophagy caused by PD inhibits apoptosis by protecting the cells.

Desai R, Jain R, Dandekar P. Surfactants reduce aggregation of monoclonal antibodies in cell culture medium with improvement in performance of mammalian cell culture. Biotechnol Prog 2023; 39:e3370. [PMID: 37348004 DOI: 10.1002/btpr.3370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 05/06/2023] [Accepted: 05/09/2023] [Indexed: 06/24/2023]
Abstract
Therapeutic monoclonal antibodies (mAbs) are biologics produced using mammalian cells and represent an important class of biotherapeutics. Aggregation in mAbs is a major challenge that can be mitigated by rigorous and reproducible upstream and downstream approaches. The impact of frequently used surfactants, like polysorbate 20, polysorbate 80, poloxamer 188, and 2-hydroxypropyl-beta-cyclodextrin, on aggregation of mAbs during cell culture was investigated in this study. Their impact on cell proliferation, viability, and mAb titer was also investigated. Polysorbate 20 and polysorbate 80 at the concentration of 0.01 g/L and poloxamer 188 at the concentration of 5 g/L were found to be effective in reducing aggregate formation in cell culture medium, without affecting the cell growth or viability. Furthermore, their presence in culture media resulted in increased cell proliferation as compared to the control group. Addition of these surfactants at the specified concentrations increased monomer production while decreasing high molecular weight species in the medium. After mAbs were separated, using protein "A" chromatography, flasks with surfactant exhibited improved antibody stability, when analyzed by DLS. Thus, while producing aggregation-prone mAbs via mammalian cell culture, these excipients may be employed as cell culture medium supplements to enhance the quality and yield of functional mAbs.

Mechanisms of gut epithelial barrier impairment caused by food emulsifiers polysorbate 20 and polysorbate 80. Allergy 2023; 78:2441-2455. [PMID: 37530764 DOI: 10.1111/all.15825] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 06/19/2023] [Accepted: 07/05/2023] [Indexed: 08/03/2023]
Abstract
BACKGROUND The rising prevalence of many chronic diseases related to gut barrier dysfunction coincides with the increased global usage of dietary emulsifiers in recent decades. We therefore investigated the effect of the frequently used food emulsifiers on cytotoxicity, barrier function, transcriptome alterations, and protein expression in gastrointestinal epithelial cells. METHODS Human intestinal organoids originating from induced pluripotent stem cells, colon organoid organ-on-a-chip, and liquid-liquid interface cells were cultured in the presence of two common emulsifiers: polysorbate 20 (P20) and polysorbate 80 (P80). The cytotoxicity, transepithelial electrical resistance (TEER), and paracellular-flux were measured. Immunofluorescence staining of epithelial tight-junctions (TJ), RNA-seq transcriptome, and targeted proteomics were performed. RESULTS Cells showed lysis in response to P20 and P80 exposure starting at a 0.1% (v/v) concentration across all models. Epithelial barrier disruption correlated with decreased TEER, increased paracellular-flux and irregular TJ immunostaining. RNA-seq and targeted proteomics analyses demonstrated upregulation of cell development, signaling, proliferation, apoptosis, inflammatory response, and response to stress at 0.05%, a concentration lower than direct cell toxicity. A proinflammatory response was characterized by the secretion of several cytokines and chemokines, interaction with their receptors, and PI3K-Akt and MAPK signaling pathways. CXCL5, CXCL10, and VEGFA were upregulated in response to P20 and CXCL1, CXCL8 (IL-8), CXCL10, LIF in response to P80. CONCLUSIONS The present study provides direct evidence on the detrimental effects of food emulsifiers P20 and P80 on intestinal epithelial integrity. The underlying mechanism of epithelial barrier disruption was cell death at concentrations between 1% and 0.1%. Even at concentrations lower than 0.1%, these polysorbates induced a proinflammatory response suggesting a detrimental effect on gastrointestinal health.

Int J Pharm 2023; 641:123039. [PMID: 37225026 DOI: 10.1016/j.ijpharm.2023.123039] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 04/17/2023] [Accepted: 05/05/2023] [Indexed: 05/26/2023]
Abstract
Bisdemethoxycurcumin (BDMC) is the main active ingredient that is isolated from Zingiberaceae plants, wherein it has excellent anti-tumor effects. However, insolubility in water limits its clinical application. Herein, we reported a microfluidic chip device that can load BDMC into the lipid bilayer to form BDMC thermosensitive liposome (BDMC TSL). The natural active ingredient glycyrrhizin was selected as the surfactant to improve solubility of BDMC. Particles of BDMC TSL had small size, homogenous size distribution, and enhanced cultimulative release in vitro. The anti-tumor effect of BDMC TSL on human hepatocellular carcinomas was investigated via 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method, live/dead staining, and flowcytometry. These results showed that the formulated liposome had a strong cancer cell inhibitory, and presented a dose-dependent inhibitory effect on migration. Further mechanistic studies showed that BDMC TSL combined with mild local hyperthermia could significantly upregulate B cell lymphoma 2 associated X protein levels and decrease B cell lymphoma 2 protein levels, thereby inducing cell apoptosis. The BDMC TSL that was fabricated via microfluidic device were decomposed under mild local hyperthermia, which could beneficially enhance the anti-tumor effect of raw insoluble materials and promote translation of liposome.

Poult Sci 2022; 102:102246. [PMID: 36335735 PMCID: PMC9640312 DOI: 10.1016/j.psj.2022.102246] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Revised: 09/29/2022] [Accepted: 10/08/2022] [Indexed: 11/05/2022] Open
Abstract
This study was conducted to simulate salpingitis of laying hens by observing the morphology and expression of inflammatory genes in the oviduct. A total of one hundred twenty 81-wk-old Roman Pink laying hens in good physical condition without the oviduct disease with an average egg production rate of 76% were fed a basal diet for 2 wks and then randomly allocated into 4 groups (6 replicates/group, 5 birds/replicate). The experimental treatments were as follows: 1) Control group (treated with PBS); 2) Organic chemical reagent (OCR) group; 3) Lipopolysaccharide (LPS) group; 4) LPS + OCR group. First, the chickens were kept upside down to make ectropion and exposure of the apertura uterinae; then prepared reagents were poured into the uterine part of the fallopian tube by using the chicken vas deferens (1 mL/layer); finally, the chickens were kept in the inverted position for 5 to 10 min. The fallopian tube samples (the magnum, isthmus, and uterus) were collected after 48 h of treatment. Compared with the control, treatment with LPS+OCR decreased (P < 0.05) the secondary villus length and primary villus area in magnum and villus length in isthmus (P < 0.05). An increase (P < 0.05) of the intervillous space of uterus was observed in LPS + OCR group compared with the control. The expressions of interleukin-6 mRNA of magnum and interferon-γ (IFN-γ) of isthmus in the LPS and LPS+OCR treatments were higher (P < 0.05) than that in control. Compared with the control, treatment with LPS+OCR increased (P < 0.05) the expressions of IFN-γ mRNA of magnum and IFN-γ, tumor necrosis factor-α and inducible nitric oxide synthase mRNA of uterus in laying hens. In conclusion, the results of morphological damage of fallopian tube tissue and increased expression of inflammatory factors in LPS + OCR treatment group suggested that LPS+OCR treatment can provide data basis to establish salpingitis model in laying hens for studying the pathogenesis of it.

Abstract
Abstract
This study evaluated the effect of surfactant-assisted enzymatic extraction on the quality of tiger nut milk (TNM). TNM was extracted from tiger nuts using different concentrations of xylanase (0.010–0.100%) and Tween 20 (0.005–0.010%). The yield, stability, nutritional, antioxidant, and sensory properties of the samples were determined. The yield of TNM significantly increased, by 32.72–50.67%, following surfactant-assisted enzymatic extraction. Optimum yield and stability of TNM were obtained using 0.010% xylanase and Tween 20. Enzymatic extraction significantly increased total sugar and flavonoids, however, starch, dietary fibre, protein, carotenoids, lycopene, total phenolic content, and antioxidant properties reduced significantly. The incorporation of Tween 20 stabilised these parameters. There was no significant difference in panellists' preference for the control (sample extracted without enzyme and surfactant), enzymatically-extracted, and surfactant-assisted enzymatic extracted samples in mouthfeel and aroma, however, the surfactant-assisted enzymatic extracted sample was most preferred in colour, consistency, taste, and overall acceptability. Using surfactant-assisted enzymatic extraction could prove invaluable for the production of TNM.

Protective effect of l-carnitine-loaded solid lipid nanoparticles against H 2O 2-induced genotoxicity and apoptosis. Colloids Surf B Biointerfaces 2022; 212:112365.

Abstract
L-carnitine (LC) is a highly water-soluble compound involved in the β-oxidation of lipids and transportation of long-chain fatty acids across the membrane of mitochondria. However, the higher hydrophilicity of LC limits its free diffusion across the bilayer lipid membrane of intestinal epithelium in oral administration, decreasing oral bioavailability. Drug delivery with nanoparticles enhances cargo bioavailability and cellular uptake and improves therapeutic outcomes while decreasing unwanted side effects. Here, we proposed solid lipid nanoparticles (SLNs) as a hydrophobic carrier for LC delivery, aiming at increasing LC bioavailability and its protective role against intracellular oxidative stress damages. The LC-SLNs were prepared using the hot homogenization technique, and different physicochemical properties were investigated. The inhibition of H2O2-induced ROS generation in human umbilical vein endothelial cells (HUVECs) with plain LC and LC-SLNs was investigated. Moreover, various in vitro experiments were performed to assess whether LC-SLNs can protect HUVECs from H2O2-induced genotoxicity and apoptosis. The monodispersed and spherical blank SLNs and LC-SLNs were 104 ± 1.8 and 128 ± 1.5 nm, respectively with a drug loading (DL) of 11.49 ± 0.78 mg/mL and acceptable encapsulation efficiency (EE%) (69.09 ± 1.12) of LC-SLNs. The formulation process did not affect the antioxidant properties of LC. MTT assay and comet assay demonstrated that the LC-SLNs decreased cytotoxicity and genotoxicity of H2O2, respectively on HUVECs. Besides, LC-SLNs more inhibited ROS generation, along with apoptotic events in H2O2-treated HUVECs compared to the plain LC. Altogether, our findings affirmed the protective effects of LC-SLNs against H2O2-induced genotoxicity and apoptosis in HUVECs. In conclusion, LC-SLN formulation is a promising drug delivery system to overcome the bioavailability issue of hydrophilic LC, enhancing the antioxidant and biological properties of the plain LC.

Abstract
The phosphorylation of histone variant H2AX and formation of γH2AX is a primary response to the DNA double-strand breaks (DSBs). Detection of γH2AX is a robust and sensitive tool for diagnosis of DNA damage and repair in pre-clinical drug discovery investigations. In addition, the replication stress also leads to the formation of γH2AX and cell death and so γH2AX can serve as a surrogate marker of drug-induced cytotoxicity. Recent advances in genomic research offer an opportunity to detect γH2AX as a specific biomarker for quantitative analysis of DNA damages and repair using high content screening technology and quantitative imaging analysis. The proposed approaches identify a wide range of genetic disorders and are applied in combination with other assays in drug discovery and also for the evaluation of the efficacy of various developmental drugs. In the current review, we provide recent insights into the potential of γH2AX biomarker as a powerful tool in genotoxicity analyses for the monitoring and managing of cancer diseases.

Abstract
Recycling residual industrial gases and residual biomass as substrates to biofuel production by fermentation is an important alternative to reduce organic wastes and greenhouse gases emission. Clostridium carboxidivorans can metabolize gaseous substrates as CO and CO2 to produce ethanol and higher alcohols through the Wood-Ljungdahl pathway. However, the syngas fermentation is limited by low mass transfer rates. In this work, a syngas fermentation was carried out in serum glass bottles adding different concentrations of Tween® 80 in ATCC® 2713 culture medium to improve gas-liquid mass transfer. We observed a 200% increase in ethanol production by adding 0.15% (v/v) of the surfactant in the culture medium and a 15% increase in biomass production by adding 0.3% (v/v) of the surfactant in the culture medium. The process was reproduced in stirred tank bioreactor with continuous syngas low flow, and a maximum ethanol productivity of 0.050 g/L.h was achieved.

Abstract
Acriflavine (ACF) is an antiseptic compound with the potential antitumor activity which is used for the fluorescent staining of RNA due to its dominant fluorescent emission at ∼515 nm. Here, solid lipid nanoparticles (SLNs) containing ACF (ACF-SLNs) were prepared and their physicochemical properties, potential geno/cytotoxicity, as well as the fluorescent properties were investigated. FITC-annexin V/PI staining and cell cycle assays were carried out to find the type of cellular death caused. Particle size analysis and SEM images revealed that spherical ACF-SLNs had a homogeneous dispersion with a mean diameter of 106 ± 5.7 nm. Drug loading (DL) of 31.25 ± 4.21 mg/mL and high encapsulation efficiency (EE%) (89.75 ± 5.44) were found. ACF-SLNs physically were relatively stable in terms of dispersion, size, and EE. The uptake study demonstrated the potential use of fluorescent ACF-SLNs in bio-distribution studies. MTT assay showed that plain ACF could induce growth inhibition of A549 cells with IC50 of 8.5, 6, and 4.5 μMol after 24, 48, and 72 hours, respectively, while ACF-SLNs had stable cytotoxic effects after 48 hours. ACF-SLNs induced remarkable apoptosis and even necrosis after 48 h. Conclusively, ACF-SLNs with acceptable physicochemical features showed increased bioimpacts after 48 h compared to plain ACF.

Abstract
Lawsone (LWS) is a naphthoquinone-type dye with potential antitumor activity. LWS is used in cosmetics for coloring hair, skin, and nails. In this study, solid lipid nanoparticles (SLNs) containing LWS were prepared using a hot homogenization technique. Physicochemical properties of LWS-SLNs including encapsulation efficiency (EE), drug loading (DL), size, zeta potential, homogeneity, in vitro release, and kinetics of release were determined. The potential cytotoxic properties of LWS-SLNs were investigated. Comet assay was done to assess the genotoxicity of LWS-SLNs. The scanning electron microscopy (SEM) images revealed that LWS-SLNs were spherical and homogeneously dispersed. The average diameter of free SLNs and LWS-SLNs were 97 ± 1.4 and 127 ± 3.1 nm, respectively with high EE% (95.88 ± 3.29) and a DL of 22.72 ± 1.39 mg/mL of LWS-SLNs. The plain LWS could induce growth inhibition of A549 cells with IC50 of 17.99 ± 1.11, 13.37 ± 1.22, and 9.21 ± 1.15 μg/mL after 24, 48, and 72 h, respectively, while LWS-SLNs had more cytotoxic effects after 48 h (9.81 ± 1.3 μg/mL). Comet assay represented clear fragmentation in the chromatin of the treated cells. Besides, LWS-SLNs (13.37 ± 1.22 μg/mL) induced ∼52 % apoptosis and even necrosis after 48 h. The qPCR results showed an enhanced downregulation of Bcl-2 and upregulation of Casp 9 due to the treatment of A549 cells with LSW-SLNs. In conclusion, a stable formulation of LWS-SLN was prepared with good physicochemical features and long-term biological effects that candidate it for in vivo trials.

Abstract
Human exposure to silica nanoparticles (SNPs) and formaldehyde (FA) is increasing and this has raised some concerns over their possible toxic effects on the exposed working populations. Notwithstanding several studies in this area, the combined toxicological effects of these contaminants have not been yet studied. Therefore, this in vitro study was designed to evaluate the SNPs and FA combined toxicity on human lung epithelial cells (A549 cells). The cells were exposed to SNPs and FA separately and in combined form and the single and combined toxicity of SNPs and FA were evaluated by focusing on cellular viability, DNA damage, and apoptosis via MTT, DAPI staining, DNA ladder, and Annexin V-FITC apoptosis assays. The results showed a significant increase in cytotoxicity, DNA damage, and chromatin fragmentation and late apoptotic\necrotic rates in combined treated cells compared with SNPs and FA-treated cells (P value < 0.05). Two-factorial analysis showed an additive toxic interaction between SNPs and FA. Eventually, this can be deduced that workers exposed simultaneously to SNPs and FA may be at high risk compared with exposure to each other.

Abstract
Methotrexate (MTX), a chemotherapeutic agent, has limited clinical applications due to its pulmonary and neurotoxicity. The antineoplastic activity of MTX-NE COCO, which is MTX formulated in coconut oil nanoemulsion (NE), was evaluated in A549 non-small cell lung cancer cells while its adverse side effects on the oxidative stress of the lung and brain were assessed in mice. The z-average diameter for the dispersed nanodroplet of MTX-NE COCO (79.74 ± 3.49 nm) was considerably greater than the free-NE COCO (64.80 ± 3.34 nm). In contrast, the magnitude of the negative z-potential of MTX-NE COCO (3.00 ± 0.69 mV) was markedly less than that of free-NE COCO (8.20 ± 0.76 mV). The minimum inhibitory concentration (IC50) of MTX-NE COCO (18 ± 1.8 µM) was less than the IC50 of free MTX (32 ± 1.2 µM) by around twofold. The in vivo evaluation of the MTX-NE COCO treatment revealed that the antioxidant enzymes activities of the brain and lung tissues, catalase, superoxide dismutase, and glutathione reductase, were relatively raised while the malondialdehyde amount was diminished when compared to the free MTX treatment. In conclusion, combining MTX with coconut oil in a NE had improved its efficacy while ameliorating its oxidative stress effect on the brain and lungs.

Abstract
Background: Folic acid is essential in many metabolic processes and DNA synthesis. Nevertheless, folic acid is not stable, pH-sensitive, and deteriorated upon light exposure. Objective: This work was aimed to improve folic acid stability within vitamin E-based nanoemulsion. Methods: The nanoemulsion was prepared with self-nanoemulsification method by mixing vitamin E oil, Tween 20, and PEG 400. A pseudoternary phase diagram was constructed with aqueous titration to determine the optimum ratio for the mixture. The globule size, pH and entrapment efficiency were included in the nanoemulsion characterizations. In addition, the influence of centrifugation, storage, and pH on physical and chemical stabilities of folic acid nanoemulsion was evaluated. Results: Optimum formula was obtained from vitamin E, Tween 20, and PEG 400 with the ratio of 1:11:1, and the folic acid amount was 8 mg. The size of folic acid-loaded oil globule was 15.10 ± 1.51 nm, and the nanoemulsion pH was 6.24 ± 0.01. The nanoemulsion system was able to load the folic acid completely. Folic acid in nanoemulsion was stable after 14 days at room temperature, and it was more stable compared to folic acid in solution. In addition, the physical and chemical characteristics of folic acid in nanoemulsion was not affected by the simulated gastric condition. Conclusion: Hence, nanoemulsion is a promising strategy to enhance folic acid stability.

Abstract
Ethambutol hydrocloride (EMB) is an anti-tuberculosis drug, which is commonly used as a protection agent against of unrecognized resistance to other drugs employed to treat this disease. Since oral form of EMB has some side effects and cellular toxicity, direct administration of EMB into lungs seems to be an attractive and reasonable option in order to overcome these side effects. Our main goal in this study was assessment of pulmonary administration through dry powder inhaler (DPI) using EMB-loaded solid lipid nanoparticles (SLNs). We prepared EMB-loaded SLNs using two techniques (hot homogenization and ultrasonication). DPI formulations were made by spray drying of EMB-loaded SLNs with and without mannitol. For investigation of flowbility of the prepared powders, Carr's index and Hausner ratio, and for in vitro deposition of the powders, Next Generation Impactor (NGI) analysis were used. The encapsulation efficiency and particle size of obtained particles were higher than 98% and sub-100 nm, respectively. Toxicity investigation of EMB-loaded SLNs via MTT assay showed biocompatibility and non-toxicity of the SLNs. Results of flowability and aerodynamic traits assessment of EMB-loaded SLN DPI powder confirmed the suitability of prepared powders. Overall, the attained results showed that EMB-loaded SLN DPI has high potential for direct treatment of tuberculosis.

Abstract
Amphipathic, nonionic, surfactants are widely used in pharmaceutical, food, and agricultural industry to enhance product features; as pharmaceutical excipients, they are also aimed at increasing cell membrane permeability and consequently improving oral drugs absorption. Here, we report on the concentration- and time-dependent succession of events occurring throughout and subsequent exposure of Caco-2 epithelium to a "typical" nonionic surfactant (Kolliphor HS15) to provide a molecular explanation for nonionic surfactant cytotoxicity. The study shows that the conditions of surfactant exposure, which increase plasma membrane fluidity and permeability, produced rapid (within 5 min) redox and mitochondrial effects. Apoptosis was triggered early during exposure (within 10 min) and relied upon an initial mitochondrial membrane hyperpolarization (5-10 min) as a crucial step, leading to its subsequent depolarization and caspase-3/7 activation (60 min). The apoptotic pathway appears to be triggered prior to substantial surfactant-induced membrane damage (observed ≥60 min). We hence propose that the cellular response to the model nonionic surfactant is triggered via surfactant-induced increase in plasma membrane fluidity, a phenomenon akin to the stress response to membrane fluidization induced by heat shock, and consequent apoptosis. Therefore, the fluidization effect that confers surfactants the ability to enhance drug permeability may also be intrinsically linked to the propagation of their cytotoxicity. The reported observations have important implications for the safety of a multitude of nonionic surfactants used in drug delivery formulations and to other permeability enhancing compounds with similar plasma membrane fluidizing mechanisms.

Abstract
The topical administration of exogenous human epidermal growth factor (hEGF) is a promising approach for improved chronic wound therapy. To develop therapeutically superior hEGF formulation, we prepared hEGF-containing neutral (NDLs), cationic (CDLs) and anionic (ADLs) deformable liposomes (DLs), respectively, since it is expected that the liposomal surface charge can affect both the liposomal physicochemical properties, their skin penetration potential and therapeutic efficacy of liposome-associated drug. All prepared liposomes were of similar size (300-350 nm) with high hEGF load (~80% entrapment efficacy). Among the studied DLs, ADLs were found to be most promising for sustained release of hEGF, as assessed in vitro using the polyamide membrane. Ex vivo studies revealed that all DLs were excellent systems for skin therapy with hEGF and no penetration of hEGF through the full thickness human skin was detected. ADLs provided a depot exhibiting the highest hEGF retention onto the human skin surface. ADLs also revealed enhanced mitogenic activities in human fibroblasts compared to both NDLs and CDLs after 48 hrs treatment. Moreover, hEGF-containing ADLs significantly enhanced mitogenic activity in fibroblast as compared to activity of hEGF solution (positive control). Similar trends were observed in human keratinocytes after 24 hrs of treatment. We proved that the liposomal surface charge affects the therapeutic potential of hEGF-containing liposomes. hEGF-containing ADLs can be a promising nanosystem-based formulation for localized therapy of chronic wounds.

Abstract
Linear alkylbenzene Sulphonate (LAS) is the anionic surfactant component of globally consumed detergents. Exposure of sub-inhibitory fractions viz., 1/10th (T1), 1/5th (T2), and 1/2.5th (T3) of IC50 for 48 h, of LAS (5 μM, 10 μM, and 20 μM, respectively) to viable C6 glioma cells of rat, besides imparting morphological alterations leads to gross cytotoxicity. Expression of the damaged DNA coupled with cleaved PARP (p < 0.05; p < 0.01 and p < 0.001) were recorded for T1, T2 and T3, respectively. Subsequently, the cell cycle at G2/M check point was significantly arrested (p < 0.05 for T1 and T2; p < 0.01 for T3). The flow cytometric analysis reveals the initiation of apoptosis in C6 cells as is evident by a significant increase (p < 0.01 for T1, p < 0.001 for T2, and T3) in the intake of annexin-V, the calcium dependent apoptotic phospholipid binding protein. Moreover, significantly increased reactive oxygen species (ROS) (p < 0.05; p < 0.01 and p < 0.001) after 6 h of exposure for all the three sets, registered a declining trend (P < 0.001) when T3 cells were co-treated with N-acetyl cysteine (NAC). Furthermore, the significant attenuation (p < 0.01) of expression of the cleaved PARP and a consequent decrease (p < 0.05) in the cell cycle arrest at G2/M phase after scavenging ROS induced oxidative stress by treating C6 cells with NAC clearly evinces that LAS induced apoptosis is mediated by intracellular ROS. Thus, these findings provide a tangible basis for further investigations including in vivo studies, to unravel the molecular mechanism involved in ROS mediated and LAS induced cytotoxic manifestations.

Abstract
Nowadays, the safety of parabens as pharmaceutical preservatives is debated. Recent studies investigated their interference with the oestrogen receptors, nevertheless their carcinogenic activity was also proved. That was the reason why the re-evaluation of the biocompatibility and antimicrobial activity of parabens is required using modern investigation methods. We aimed to test the cytotoxic, antifungal and antibacterial effect of parabens on Caco-2 cells, C. albicans, C. parapsilosis, C. glabrata, E. coli, P. aeruginosa and S. aureus. Two complex systems (glycerol-Polysorbate 20; ethanol-Capryol PGMC™) were formulated to study-with the MTT-assay and microdilution method, respectively-how other excipients may modify the biocompatibility and antimicrobial effect of parabens. In the case of cytotoxicity, the toxicity of these two systems was highly influenced by co-solvents and surfactants. The fungi and bacteria had significantly different resistance in the formulations and in some cases the excipients could highly modify the effectiveness of parabens both in an agonistic and in a counteractive way. These results indicate that with appropriate selection, non-preservative excipients can contribute to the antimicrobial safety of the products, thus they may decrease the required preservative concentration.

Abstract
BACKGROUND AND OBJECT Polyelectrolyte microcapsule is a promising candidate for multifunctional drug delivery system. However, the lack of reports about animal experiments have greatly slowed down their development for drug delivery. We engineered biodegradable chitosan-alginate polyelectrolyte multilayer capsule filled with bovine serum albumin gel (BSA-gel-capsule). Herein, we demonstrated their applicability for local chemotherapy, a means of treating local or regional malignancies by direct administration of anti-tumor agents to tumor sites. METHOD Doxorubicin (DOX) was loaded in BSA-gel-capsules and DOX-resistant cell line (MCF-7/ADR cells) was employed for antitumor studies in vitro. The cytotoxicity, cellular uptake and distribution of DOX from BSA-gel-capsules were studied. Afterwards, MCF-7/ADR xenografts tumor model was established in nude mice. The in vivo antitumor efficacy of DOX-loaded BSA-gel-capsules by intratumor injection was then evaluated. RESULT Compared with free DOX, more effective cytotoxicity against MCF-7/ADR cells after treatment with DOX-loaded BSA-gel-capsules was revealed, demonstrating the positive reversal effect on drug-resistance. Thereafter, the more cellular uptake and nucleus distribution of DOX from BSA-gel-capsules in MCF-7/ADR cells provided convincing explanation for the reversal effect. DOX-loaded BSA-gel-capsules displayed remarkably more antitumor efficacy than free DOX in MCF-7/ADR cell-xenografted mice. Finally, the high DOX accumulation and prolonged retention in tumor site after local administration of DOX-loaded BSA-gel-capsules was demonstrated, displaying the unique advantages of BSA-gel-capsules for local chemotherapy. CONCLUSION These findings indicate that DOX-loaded BSA-gel-capsules should be considered a potential candidate for the treatment of drug-resistant breast cancer. This paper provides a feasibility for the local chemotherapy of polyelectrolyte microcapsules, which will be a big step towards their application as drug delivery vehicles.

Abstract
Cytotoxicity and genotoxicity of sodium acetate (SA), sodium diacetate (SDA), and potassium sorbate (PS) was tested on Human Umbilical Vein Endothelial Cells (HUVEC). Cytotoxicity was investigated by MTT assay and flow cytometry analysis, while genotoxicity was evaluated using DNA fragmentation and DAPI staining assays. The growth of treated HUVECs with various concentrations of SA, SDA and PS decreased in a dose-and time-dependent manner. The IC50 of 487.71, 485.82 and 659.96 µM after 24 h and IC50 of 232.05, 190.19 and 123.95 µM after 48 h of treatment were attained for SA, SDA and PS, respectively. Flow cytometry analysis showed that early and late apoptosis percentage in treated cells was not considerable. Also neither considerable DNA fragmentation nor DNA smear was observed using DAPI staining and DNA ladder assays. Overall, it can be concluded that the aforementioned food additives can be used as safe additives at low concentration in food industry.

Abstract
Oxidative stress possesses a key role in the onset and development of cardiovascular diseases (CVDs), thus it can be an efficient target to tackle such ailment. Marrubiin, a bioactive diterpene, is a potent antioxidant against oxidative stress. Herein, we aimed to formulate marrubiin loaded solid lipid nanoparticles (SLNs) to improve its pharmacokinetics and bioavailability and also to investigate free drug and formulation's protective impact against intracellular reactive oxygen species (ROS) generation in HUVECs. Marrubiin-SLNs were formulated using hot homogenization/solidification method and then were subjected to physicochemical characterizations, i.e. size, zeta potential, morphology, polydispersity index (PDI), encapsulation efficiency (% EE), drug loading/content and physical stability assessments. MTT assay was performed to study the cytotoxicity of the intact and SLN incorporated marrubiin on HUVECs. Further, the antioxidant property of marrubiin and formulations was evaluated using DPPH radical scavenging assay and their protective effect against TNF-α induced oxidative stress was assessed by the means of intracellular ROS assessment, and also apoptosis/necrosis, cell cycle, and DNA fragmentation assays. Electron microscopy analysis showed spherical monodispersed SLNs with the size less than 100 nm, particle/zeta size analyses also approved the size of particles with a zeta potential of -1.28 ± 0.17 mV. Results also showed high EE (98%), drug loading (31.74 mg/g) with 3.15% drug content. In vitro release studies revealed about 90% of marrubiin cumulative release during 24 h. The stability of marrubiin-SLNs in terms of size, zeta potential, polydispersity index, EE and drug leakage was approved. Marrubiin antioxidant stability after formulation was approved by DPPH analysis. MTT cell survival assay showed no significant cytotoxicity after 24 h and 48 h. Intracellular ROS detection assay revealed that marrubiin and marrubiin-SLNs, play protective effect against TNF-α induced oxidative stress in HUVECs which was further approved by apoptosis assessment. Conclusively, based on our findings, marrubiin nanoparticles are proposed as a preventive/therapeutic remedy against disorders elicited by increased levels of intracellular ROS in CVDs.

Abstract
BACKGROUND Drug delivery-based nanoparticles have been emerged to be an alternative and efficient approach to cancer therapy compared to conventional systems. Here, we investigated the role of all-trans retinoic acid (ATRA) formulated with precirol in increasing doxorubicin (Dox) induced apoptosis and cell cycle arrest in MDA-MB-231 breast cancer cells. METHODS ATRA-loaded Nano structured lipid carriers (NLCs) were evaluated in terms of particle size, zeta potential, Fourier transforms infrared spectroscopy (FTIR), cell internalization, and scanning electron microscope (SEM). To understand molecular mechanism of apoptosis and cell cycle progression flow cytometric assay, MTT and DAPI staining was applied. Real time (RT)-PCR analysis was employed to investigate the expression of apoptosis related genes, including Survivin, Bcl-2 and Bax. RESULTS The optimized ATRA formulation exhibited average particle size of 95±5nm with nearly narrow size distribution. The IC50 values for ATRA and doxorubicin were 48±0.4μM and 0.81±0.02μM, respectively. ATRA-loaded NLCs decreased percentage of cell proliferation from 51±7.2% to 36±4.1% (p <0.05). Co-treatment of the MDA-MB-231 cells with ATRA formulation and doxorubicin caused two-fold increase in the percentage of apoptosis (p<0.05). The results from gene expression exhibited a significant decrease in survivin along with increase at Bax mRNA levels accompanied by a slight increase in Bax/Bcl-2 ratio. CONCLUSION Our results propose that ATRA encapsulated in precirol as a biocompatible compound augments the efficacy of Dox in cancer therapy.

Abstract
Non-small cell lung cancer (NSCLC) patients with sensitizing mutations in the exons 18-21 of the epithelial growth factor receptor (EGFR) gene show increased kinase activity of EGFR. Hence, tyrosine kinase inhibitors (TKIs) such as erlotinib (ETB) have commonly been used as the second line therapeutic option for the treatment of metastatic NSCLC. While the ETB is available as an oral dosage form, the local delivery of this TKI to the diseased cells of the lung may ameliorate its therapeutic impacts. In the current study, we report on the development of ETB-loaded solid lipid nanoparticle (SLN) based formulation of dry powder inhaler (ETB-SLN DPI). ETB-SLNs were formulated using designated amount of compritol/poloxamer 407. The engineered ETB-SLNs showed sub-100 nm spherical shape with an encapsulation efficiency of 78.21%. MTT assay and DAPI staining revealed that the ETB-SLNs enhanced the cytotoxicity of cargo drug molecules in the human alveolar adenocarcinoma epithelial A549 cells as a model for NSCLC. To attain the ETB-SLN DPI, the ETB-SLNs were efficiently spray dried into microparticles (1-5 μm) along with mannitol. The ETB-SLN DPI powder displayed suitable flowability and aerodynamic traits. The Carr's Index, Hausner ratio and Next Generation Impactor (NGI) analyses confirmed deep inhalation pattern of the formulation. Based on these findings, we propose the ETB-SLN DPI as a promising treatment modality for the NSCLC patients.

Abstract
In this study, a nanoemulsion formulation for encapsulating turmeric extract was developed and its physicochemical characteristics including particle diameter, zeta potential, polydispersity index, and stability were determined. The turmeric nanoemulsion (TE-NE) droplets exhibited small diameter (165 nm), low PDI (0.17), and high zeta potential (−31.80 mV), all desirable characteristics in nanoemulsions, as well as stability in a wide range of pH. The TE-NE was spray-dried as a means to allow its incorporation into food products and reduce potential transport and storage costs. The resulting powder exhibited a pale yellowish appearance and had a curcuminoids content of 0.39 mg/g. The spray-dried TE-NE powder was incorporated into minced pork to make canned ham, and the sensory characteristics of the ham were evaluated. As a result, the canned ham incorporating TE-NE powder received the same overall acceptability score as the control, and only exhibited slight yellowing. By contrast, ham incorporating turmeric extract exhibited substantial yellowing, and its appearance was considered less acceptable by the panelists. Therefore, the TE-NE formulation could be incorporated into canned ham and other meat products without substantially affecting their sensory qualities.

Abstract
This study investigated the role of interfacial myofibrillar protein (MFP) in the oxidative stabilization of meat emulsions. Emulsions with 10% oil were prepared using either 2% (w/v) Tween 20 or 0.25, 0.5, and 1% (w/v) MFP and then subjected to hydroxyl radical oxidation at 4 °C for 0, 2, and 24 h. MFP was more readily oxidized (intrinsic fluorescence quenching, sulfur losses, and carbonyl formation) than oil [conjugated dienes and 2-thiobarbituric acid-reactive substances (TBARS)]. However, oxidized MFP in the continuous phase stimulated lipid oxidation after 24 h, sharply contrasting with interface-adsorbed MFP that inhibited TBARS formation nearly 90% (p < 0.05). Interfacial MFP from 2 h oxidized samples exhibited greater losses of fluorescence and more extensive polymerization of myosin (detected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis) than MFP present in the continuous phase. Results indicated that, due to the physical localization, interface-adsorbed MFP in general and myosin in particular provided accentuated protection of emulsions against oxidation.

Abstract
The potential health risk associated with excessive dietary intake of fat and cholesterol has led to a renewed interest in replacing animal fat with nutritionally-balanced unsaturated oil in processed meats. However, as oils are more fluid and unsaturated than fats, one must overcome the challenge of maintaining both physical and chemical (oxidative) stabilities of prepared emulsions. Apart from physical entrapments, an emulsion droplet to be incorporated into a meat protein gel matrix (batter) should be equipped with an interactive protein membrane rather than a small surfactant, and the classical DLVO stabilization theory becomes less applicable. This review paper describes the steric effects along with chemical roles (radical scavenging and metal ion chelation) of proteins and their structurally modified derivatives as potential interface-building materials for oxidatively stable meat emulsions.

γ-H2AX induced by linear alkylbenzene sulfonates is due to deoxyribonuclease-1 translocation to the nucleus via actin disruption. Mutat Res 2015; 777:33-42. [PMID: 25938903 DOI: 10.1016/j.mrfmmm.2015.04.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2014] [Revised: 04/02/2015] [Accepted: 04/07/2015] [Indexed: 12/25/2022]
Abstract
Phosphorylation of histone H2AX (γ-H2AX) occurs following formation of DNA double strand breaks (DSBs). Other types of DNA damage also generate DSBs through DNA replication and repair, leading to the production of γ-H2AX. In the present study, we demonstrated that linear alkylbenzene sulfonates (LAS), the most widely used and non-genotoxic anionic surfactants, could generate γ-H2AX via a novel pathway. Breast adenocarcinoma MCF-7 cells were treated with five kinds of LAS with alkyl chains ranging from 10 to 14 carbon units (C10-C14LAS). The generation of DSBs and subsequent production of γ-H2AX increased in a manner that depended on the number of carbon units in LAS. γ-H2AX could also be generated with non-cytotoxic doses of LAS and was independent of the cell cycle, indicating the non-apoptotic and DNA replication-independent formation of DSBs. The generation of γ-H2AX could be attenuated by EGTA and ZnCl2, deoxyribonuclease-1 (DNase I) inhibitors, as well as by the knockdown of DNase I. LAS weakened the interaction between DNase I and actin, and the enhanced release of DNase I was dependent on the number of carbon units in LAS. DNase I released by the LAS treatment translocated to the nucleus, in which DNase I attacked DNA and generated γ-H2AX. These results suggested that the LAS-induced generation of γ-H2AX could be attributed to the translocation of DNase I to the nucleus through the disruption of actin, and not to LAS-induced DNA damage.

Abstract
CONTEXT Galbanic acid (GBA) is a sesquiterpene coumarin with different medicinal properties and anticancer effects. OBJECTIVE To improve the anticancer activities of GBA, in the current study, we aimed to fabricate GBA-loaded solid lipid nanoparticles (GBA-SLNs) and study their biological activities in vitro. MATERIALS AND METHODS Hot homogenization was used for preparation of GBA-SLNs. The encapsulation efficiency (EE) and drug loading (DL) and in vitro release were determined. MTT, DAPI, DNA fragmentation, comet, and Anexin V apoptosis assays were used to compare the anti-cell proliferation and genotoxicity properties of GBA and GBA-SLNs against A549 cells and HUVEC to detect apoptosis and DNA damage in the final concentration of 100 µM after 48 h treatment. RESULTS Scanning electron microscopy (SEM) and particle size analysis showed spherical SLNs (92 nm), monodispersed distribution, and zeta potential of -23.39 mV. High EE (>98%) and long-term in vitro release were achieved. The stability of GBA-SLNs in aqueous medium was approved after 3 months in terms of size and polydispersity index. GBA was able to inhibit A549 growth with an IC50 value of 62 µM at 48 h. Although GBA-SLNs could also inhibit the growth rate of A549 cells, the effect is perceived after 48 h, as approved by the quantitative expression of Bcl-xL and Casp 9 genes, and also genotoxicity assays. CONCLUSION Long-term apoptotic effect of GBA-SLNs compared with GBA may be due to the accumulation of GBA-SLNs in the tumor site because of deviant tumor pathology. Our data confirmed that SLNs could be exploited for sustained lipophilic GBA delivery.

Introduction: Dorema glabrum (Apiaceae) is a rare and monocarpic species distributed in Transcaucasia and North West of Iran. We aimed to explore anti-cancer potency of bioactive compounds from the seeds of Dorma glabrum.
Methods: Methanol extract was subjected to phytochemical investigation using normal phase Sep-pak and reversed-phase HPLC, and cytotoxic effect of isolated compounds on CAOV-4 cell line was evaluated. Furthermore, Annexin V/PI staining and comet assay were used to study genotoxicity of compounds.
Results: Diglucosyl caffeoyl ester (1), Glucopyranosylcaffeic acid (2) and skimmin (3), were identified. MTT cytotoxicity assay showed growth inhibition of CAOV-4 cells due to treatment with compunds (1), (2) and (3) with an IC50 of 99.7, 87.3 and 70.03 μg/ml at 48 h, respectively. Annexin V-FITC/PI staining showed occurrence of early/late apoptosis in the (1)-treated cells, while (2)-and (3)-treated cells necrosis/late apoptosis was dominant event. Single/double strands DNA breakages were observed by comet assay in all treatments.
Conclusion: This work provides sufficient information about anti-cancer properties of the diglucosyl caffeoyl ester from the seeds of D. glabrum.

Abstract
The pressing issue to feed the increasing world population has created a demand to enhance food production, which has to be cheaper, but at the same time must meet high quality standards. Taste, appearance, texture, and microbiological safety are required to be preserved within a foodstuff for the longest period of time. Although considerable improvements have been achieved in terms of food additives, some are still enveloped in controversy. The lack of uniformity in worldwide laws regarding additives, along with conflicting results of many studies help foster this controversy. In this report, the most important preservatives, nutritional additives, coloring, flavoring, texturizing, and miscellaneous agents are analyzed in terms of safety and toxicity. Natural additives and extracts, which are gaining interest due to changes in consumer habits are also evaluated in terms of their benefits to health and combined effects. Technologies, like edible coatings and films, which have helped overcome some drawbacks of additives, but still pose some disadvantages, are briefly addressed. Future trends like nanoencapsulation and the development of "smart" additives and packages, specific vaccines for intolerance to additives, use of fungi to produce additives, and DNA recombinant technologies are summarized.

Abstract
We previously demonstrated that the nonionic surfactants, nonylphenol polyethoxylates (NPEOs) induced the phosphorylation of histone H2AX (γ-H2AX), accompanied by DNA double-strand breaks (DSBs), and that exposure to ultraviolet (UV) degraded NPEOs, which sometimes enhanced their DNA-damaging ability. In this study, we showed that linear alkylbenzene sulfonates (LAS), general anion surfactants, also generated DSBs with γ-H2AX, and this ability was attenuated by UVB exposure. In the human breast adenocarcinoma cell line, MCF-7, γ-H2AX was generated in a dose-dependent manner immediately after cells were treated with LAS, and this was attributed to the formation of DSBs and was independent of cell cycle phases. The ability to generate γ-H2AX was markedly reduced in LAS exposed to UVB. HPLC analysis revealed that LAS were a mixture of various alkyl chain lengths, the peaks of which were detected at individual retention times. UVB evenly decreased all peaks of LAS, without migration of peaks to other retention times, which indicated that UVB may degrade the benzene ring of LAS, but did not shorten the alkyl chains. UVB is an important environmental factor in the degradation of LAS exhibiting the ability to induce DSBs, the most serious type of DNA damage.
