Abstract
Docetaxel (DTX) is one of the chemotherapeutic drugs indicated as a first-line treatment against metastatic prostate cancer (mPCa). This study aimed to compare the impact of DTX on mPCa (DU-145) tumor cells cultured as 2D monolayers and 3D multicellular tumor spheroids (MCTS) in vitro. The cells were treated with DTX (1-96 µM) at 24, 48, or 72 hr in cell viability assays (resazurin, phosphatase acid, and lactate dehydrogenase). Cell death was assessed with fluorescent markers and proliferation by clonogenic assay (2D) and morphology, volume, and integrity assay (3D). The cell invasion was determined using transwell (2D) and extracellular matrix (ECM) (3D). Results showed that DTX decreased cell viability in both culture models. In 2D, the IC50 (72 hr) values were 11.06 μM and 14.23 μM for resazurin and phosphatase assays, respectively. In MCTS, the IC50 values for the same assays were 114.9 μM and 163.7 μM, approximately 10-fold higher than in the 2D model. The % of viable cells decreased, while the apoptotic cell number was elevated compared to the control in 2D. In 3D spheroids, only DTX 24 μM induced apoptosis. DTX (≥24 μM at 216 hr) lowered the volume, and DTX 96 μM completely disintegrated the MCTS. DTX reduced the invasion of mPCa cells to matrigel (2D) and migration from MCTS to the ECM. Data demonstrated significant differences in drug response between 2D and 3D cell culture models using mPCa DU-145 tumor cells. MCTS resembles the early stages of solid tumors in vivo and needs to be considered in conjunction with 2D cultures when searching for new therapeutic targets.

Abstract
Introduction Early-life osteosarcoma is associated with severe morbidity and mortality, particularly affecting young children and adults. The present cancer treatment regimen is exceedingly costly, and medications like ifosfamide, doxorubicin, and cisplatin have unneeded negative effects on the body. With the introduction of hyphenated technology to create medications based on plant molecules, the application of ayurvedic medicine as a new dimension (formulation, active ingredients, and nanoparticles) in the modern period is rapidly growing. The primary source of lead compounds for the development of medications for avariety of ailments is plants and their products. Traditionally, Cuminum cyminum (cumin) has been used as medication to treat a variety of illnesses and conditions. Methods The cumin seed was successfully extracted with solvents Hexane, Chloroform, Methanol, Ethanol and Acetone. Following the solvent extraction, the extract residue was assayed in MG63 cells for their anti-proliferative properties. Results First, we used the [3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide] (MTT) assay to test the extracted residue's cytotoxicity. The results show that hexane extract Half-maximal inhibitory concentration (IC50 86 µG/mL) effciently inhibits cells by causing programmed cell death. Furthermore, using the Acridine orange/ethidium bromide (AO/EB) staining method, the lactate dehydrogenase assay, and the reactive oxygen species assay using the Dichloro-dihydro-fluorescein diacetate (DCHFDA) staining method, we have demonstrated that the hexane extract causes apoptosis in MG63 cells. Furthermore, flow cytometry research revealed that the hexane extract stops the cell cycle in the S phase. In addition, the hexane extract limits colony formation and the migration potential as shown by the scratch wound healing assay. Furthermore, the extract from cumin seeds exhibits remarkable bactericidal properties against infections that are resistant to drugs. Gas chromatography analysis was used to quantitatively determine the hexane and methanolic extract based on the experimental data. The primary chemical components of the extract are revealed by the study, and these help the malignant cells heal. The present study finds that there is scientific validity in using cumin seeds as a novel method of anticancer therapy after undergoing both intrinsic and extrinsic research.

A Novel Mitochondria-Targeting Iron Chelator Neuroprotects Multimodally via HIF-1 Modulation Against a Mitochondrial Toxin in a Dopaminergic Cell Model of Parkinson's Disease. Mol Neurobiol 2023; 60:749-767.

Abstract
Coumarins are plant-derived polyphenolic compounds belonging to the benzopyrones family, possessing wide-ranging pharmaceutical applications including cytoprotection, which may translate into therapeutic potential for multiple diseases, including Parkinson's disease (PD). Here we demonstrate the neuroprotective potential of a new polyhydroxyl coumarin, N-(1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)-2-(7-hydroxy-2-oxo-2H-chromen-4-yl)acetamide (CT51), against the mitochondrial toxin 1-methyl-4-phenylpyridinium (MPP+). MPP+'s mechanism of toxicity relates to its ability to inhibit complex I of the mitochondrial electron transport chain (METC), leading to adenosine triphosphate (ATP) depletion, increased reactive oxygen species (ROS) production, and apoptotic cell death, hence mimicking PD-related neuropathology. Dopaminergic differentiated human neuroblastoma cells were briefly pretreated with CT51, followed by toxin exposure. CT51 significantly restored somatic cell viability and neurite processes; hence, the drug targets cell bodies and axons thereby preserving neural function and circuitry against PD-related damage. Moreover, MPP+ emulates the iron dyshomeostasis affecting dopaminergic neurons in PD-affected brains, whilst CT51 was previously revealed as an effective iron chelator that preferentially partitions to mitochondria. We extend these findings by characterising the drug's interactive effects at the METC level. CT51 did not improve mitochondrial coupling efficiency. However, voltammetric measurements and high-resolution respirometry analysis revealed that CT51 acts as an antioxidant agent. Also, the neuronal protection afforded by CT51 associated with downregulating MPP+-induced upregulated expression of hypoxia-inducible factor 1 alpha (HIF-1α), a protein which regulates iron homeostasis and protects against certain forms of oxidative stress after translocating to mitochondria. Our findings support the further development of CT51 as a dual functioning iron chelator and antioxidant antiparkinsonian agent.

Chemical characterization of Brazilian savannah Byrsonima species (muricis) and their impact on genomic instability and chemopreventive effects. MUTATION RESEARCH/GENETIC TOXICOLOGY AND ENVIRONMENTAL MUTAGENESIS 2023; 887:503586.

Abstract
The identification of new drugs with few or no adverse effects is of great interest worldwide. In cancer therapy, natural products have been used as chemopreventive and chemotherapeutic agents. Plants from the Brazilian savannah belonging to the Byrsonima genus are popularly known as muricis and have attracted much attention due to their various pharmacological activities. However, there are currently no data on these plants concerning their use as chemopreventive or chemotherapeutic agents in human cell lines. The present study assessed the potential of B. correifolia, B. verbascifolia, B. crassifolia, and B. intermedia extracts as natural alternatives in the prevention and/or treatment of cancer. The chemical constituents present in each extract were analyzed by electrospray ionization-mass spectrometry (ESI-MSN). The mutagenic/antimutagenic (micronucleus assay), genotoxic/antigenotoxic (comet assay), apoptotic/necrotic (acridine orange/ethidium bromide uptake), and oxidative/antioxidative (CM-H2DCFDA) effects of the extracts and their influence on gene expression (RTqPCR) were investigated in nonmetabolizing gastric (MNP01) and metabolizing hepatocarcinoma (HepG2) epithelial cells to evaluate the effects of metabolism on the biological activities of the extracts. The genotoxicity, mutagenicity, and apoptotic effects observed in HepG2 cells with B. correifolia and B. verbascifolia extracts are probably associated with the presence of proanthocyanidins and amentoflavone. In MNP01 cells, none of the four extracts showed mutagenic effects. B. crassifolia and B. intermedia extracts exhibited strong antimutagenicity and enhanced detoxification in HepG2 cells and antioxidant capacities in both types of cells, possibly due to the presence of gallic and quinic acids, which possess chemopreventive properties. This study identifies for the first time B. correifolia and B. verbascifolia extracts as potential agents against hepatocarcinoma and B. crassifolia and B. intermedia extracts as putative chemopreventive agents.

Abstract
AIM This in vitro study aimed to investigate the effect of propolis extracts from two different solvents on human submandibular salivary gland (HSG) tumor cell line. MATERIALS AND METHODS Propolis was extracted by dichloromethane (DCM) and hexane (HEX). Crude extracts were prepared from 6.25 to 200 µg/mL in Dulbecco's modified eagle medium without serum. Flavonoid and total phenolic contents of crude extracts were measured using a modified colorimetric method. The cytotoxicity was evaluated by 3-[4, 5-dimethylthiazol-2-yl]-2,5 diphenyl-tetrazolium (MTT) assay and lactate dehydrogenase (LDH) release assay. The statistics were analyzed by independent sample t-test. RESULTS Propolis extracts obtained using DCM and HEX exhibited comparable % yield (38.58 and 38.25) and physical characteristics and different amounts of flavonoid (0.439 ± 0.02 and 0.250 ± 0.01 mg catechin/g sample) and total phenolic compounds (3.759 ± 0.03 and 1.618 ± 0.03 mg gallic acid equivalents/g sample). The DCM group at 25, 50, 100, and 200 µg/mL as well as the HEX group at 50, 100, and 200 µg/mL significantly displayed a decrease in % cell viability and an increase in % cytotoxicity, compared with the untreated control group (P < 0.05). The DCM group showed the half-maximal inhibitory concentration (IC50) of MTT (42.93 ± 2.70) and LDH (34.94 ± 0.22). The HEX group showed the IC50 of MTT (61.30 ± 5.39) and LDH (42.32 ± 1.00). Propolis extracts obtained using both DCM and HEX are effective to inhibit HSG viability. CONCLUSION Regarding to the cell morphological observation, MTT and LDH assays, propolis extracts obtained using DCM and HEX exhibited the cytotoxic effect on HSG tumor cell line. Based on our knowledge, this research demonstrates the first preliminary result suggesting propolis as a natural product of choice for salivary gland cancer prevention and therapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Byrsonima fagifolia Niedenzu (Malpighiaceae) and other Byrsonima species are popularly employed in Brazilian traditional medicine in the form of preparations as cicatrizing, anti-inflammatory, and antimicrobial. AIM OF THE STUDY To characterize the phytochemical profile of the hydromethanolic extract obtained from B. fagifolia leaves (BF extract) and to evaluate the toxicity and the antifungal activity. MATERIALS AND METHODS The compounds from BF extract were isolated by HPLC and the structures were elucidated based on extensive analyses of 1D and 2D NMR spectra (HMQC, HMBC and COSY) data. The antifungal effect was determined by the broth microdilution method and the toxicity was evaluated on erythrocytes from sheep's blood and Galleria mellonella larvae. RESULTS Phytochemical investigation of the BF extract led to the isolation and characterization of pyrogallol, n-butyl gallate, 3,4-di-O-galloylquinic acid, 3,5-di-O-galloylquinic acid, 3,4,5-tri-O-galloylquinic acid, and 1,3,4,5-tetra-O-galloylquinic acid. The BF extract showed high content of galloylquinic acid derivatives reaching more than twenty-times the quercetin derivatives content, according to the quantification by HPLC. These galloylquinic acid derivatives, obtained during this study, and quercetin derivatives, previously isolated, were submitted to the antifungal assays. The BF extract inhibited yeast growth mainly against Cryptococcus spp., at concentrations of 1-16 μg/mL, comparable to isolated compounds galloylquinic acid derivatives. However, the quercetin derivatives as well as quinic acid, gallic acid, and methyl gallate showed lower antifungal effect compared with galloylquinic derivatives. In addition, the BF extract had no hemolytic effect and no toxicity on G. mellonella. CONCLUSION The phytochemical analysis revealed that galloylquinic acid derivatives are the major compounds in the leaves of B. fagifolia and they are associated to anti-cryptococcal activity and presented reduced toxicity.

Abstract
Gram-negative bacteria have a robust cell envelope that excludes or expels many antimicrobial agents. However, during infection, host soluble innate immune factors permeabilize the bacterial outer membrane. We identified two small molecules that exploit outer membrane damage to access the bacterial cell. In standard microbiological media, neither compound inhibited bacterial growth nor permeabilized bacterial outer membranes. In contrast, at micromolar concentrations, JAV1 and JAV2 enabled the killing of an intracellular human pathogen, Salmonella enterica serovar Typhimurium. S. Typhimurium is a Gram-negative bacterium that resides within phagosomes of cells from the monocyte lineage. Under broth conditions that destabilized the lipopolysaccharide layer, JAV2 permeabilized the bacterial inner membrane and was rapidly bactericidal. In contrast, JAV1 activity was more subtle: JAV1 increased membrane fluidity, altered reduction potential, and required more time than JAV2 to disrupt the inner membrane barrier and kill bacteria. Both compounds interacted with glycerophospholipids from Escherichia coli total lipid extract-based liposomes. JAV1 preferentially interacted with cardiolipin and partially relied on cardiolipin production for activity, whereas JAV2 generally interacted with lipids and had modest affinity for phosphatidylglycerol. In mammalian cells, neither compound significantly altered mitochondrial membrane potential at concentrations that killed S. Typhimurium. Instead, JAV1 and JAV2 became trapped within acidic compartments, including macrophage phagosomes. Both compounds improved survival of S. Typhimurium-infected Galleria mellonella larvae. Together, these data demonstrate that JAV1 and JAV2 disrupt bacterial inner membranes by distinct mechanisms and highlight how small, lipophilic, amine-substituted molecules can exploit host soluble innate immunity to facilitate the killing of intravesicular pathogens. IMPORTANCE Innovative strategies for developing new antimicrobials are needed. Combining our knowledge of host-pathogen interactions and relevant drug characteristics has the potential to reveal new approaches to treating infection. We identified two compounds with antibacterial activity specific to infection and with limited host cell toxicity. These compounds appeared to exploit host innate immunity to access the bacterium and differentially damage the bacterial inner membrane. Further, both compounds accumulated within Salmonella-containing and other acidic vesicles, a process known as lysosomal trapping, which protects the host and harms the pathogen. The compounds also increased host survival in an insect infection model. This work highlights the ability of host innate immunity to enable small molecules to act as antibiotics and demonstrates the feasibility of antimicrobial targeting of the inner membrane. Additionally, this study features the potential use of lysosomal trapping to enhance the activities of compounds against intravesicular pathogens.

Int Immunopharmacol 2022; 112:109206.

Abstract
Streptococcus agalactiae is one of the main pathogens associated with bovine mastitis. The invasion of S. agalactiae in bovine mammary epithelial cells (BMECs) has been implicated as a key event in the pathogenesis of mastitis. Matrine is known for its various pharmacological activities, such as immune response regulation and anti-inflammation. The primary aim of the research was to investigate the preventive effect of matrine on S. agalactiae-induced inflammation in BMECs along with underlying molecular mechanisms. Our data showed matrine at the concentrations of 50-100 μg/mL promoted BMECs proliferation without infection, and decreased cytotoxicity induced by S. agalactiae. Subsequently, BMECs were pre-treated with matrine (50, 75, or 100 μg/mL) for 24 h, followed by the infection with S. agalactiae for an additional 6 h. Pretreatment with matrine followed by S. agalactiae treatment decreased cell apoptosis of BMECs. Also, pretreatment of matrine to BMECs prevented the invasion of S. agalactiae. The mRNA abundances of IL-1β, IL-6, IL-8, and TNF-α were down-regulated in S. agalactiae-infected cells pretreated with matrine. In addition, the greater ratios of protein NF-κB p-p65/p65, p-IκBα/IκBα, p-38/38, and p-ERK/ERK induced by S. agalactiae were attenuated due to matrine treatment. Furthermore, pretreatment of BMECs with matrine impeded the degradation of TAK1 induced by S. agalactiae infection. These results suggest matrine could be a potential modulator in immune response of the mammary gland. In conclusion, matrine prevents cellular damage due to S. agalactiae infection by the modulation of NF-κB and MAPK signaling pathways and pro-inflammatory cytokine production.

Abstract
Zearalenone (ZEN), one of the most prevalent non-steroidal oestrogenic mycotoxins, is primarily produced by Fusarium fungi. Due to its toxicity as an oestrogenic compound and wide distribution in feed and foods, the reproductive toxicology of ZEN exposure is of public concern. The aim of the present study was to investigate the effect of ZEN on Sertoli cells to identify apoptotic pathways induced by this compound. We found that ZEN reduced the viability and caused apoptosis in Sertoli cells in vitro. Notably, we observed that such effects were associated with a significant increase in reactive oxygen species (ROS) and the number of cells that showed positive staining for γH2AX and RAD51, enzymes essential for repairing DNA damage. There was a parallel decrease in the expression of occludin and connexin 43, proteins that are present in the testis-blood barrier and gap junctions of Sertoli cells, respectively. Overall, the present study confirms that ZEN exposure can have serious deleterious effects on mammalian Sertoli cells and offers novel insight about its molecular targets in these cells.

Particulate matter (PM 10) induces in vitro activation of human neutrophils, and lung histopathological alterations in a mouse model. Sci Rep 2022; 12:7581. [PMID: 35534522 PMCID: PMC9083477 DOI: 10.1038/s41598-022-11553-6] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Accepted: 04/26/2022] [Indexed: 01/03/2023] Open
Abstract
The epidemiological association between exposure to particulate matter (PM10) and various respiratory and cardiovascular problems is well known, but the mechanisms driving these effects remain unclear. Neutrophils play an essential role in immune defense against foreign agents and also participate in the development of inflammatory responses. However, the role of these cells in the PM10 induced inflammatory response is not yet fully established. Thus, this study aims to evaluate the effect of PM10 on the neutrophil-mediated inflammatory response. For this, neutrophils from healthy adult human donors were in vitro exposed to different concentrations of PM10. The cell viability and cytotoxic activity were evaluated by MTT. LDH, propidium iodide and reactive oxygen species (ROS) were quantified by flow cytometry. Interleukin 8 (IL-8) expression, peptidyl arginine deiminase 4 (PAD4), myeloperoxidase (MPO), and neutrophil elastase (NE) expression were measured by RT-PCR. IL-8 was also quantified by ELISA. Fluorescence microscopy was used to evaluate neutrophil extracellular traps (NETs) release. The in vivo inflammatory responses were assessed in BALB/c mice exposed to PM10 by histopathology and RT-PCR. The analysis shows that PM10 exposure induced a cytotoxic effect on neutrophils, evidenced by necrosis and LDH release at high PM10 concentrations. ROS production, IL-8, MPO, NE expression, and NETs release were increased at all PM10 concentrations assessed. Neutrophil infiltration in bronchoalveolar lavage fluid (BALF), histopathological changes with inflammatory cell infiltration, and CXCL1 expression were observed in PM10-treated mice. The results suggest that lung inflammation in response to PM10 could be mediated by neutrophils activation. In this case, these cells migrate to the lungs and release pro-inflamatory mediators, including ROS, IL-8, and NETs. Thus, contributing to the exacerbation of respiratory pathologies, such as allergies, infectious and obstructive diseases.

Front Bioeng Biotechnol 2022; 9:767256. [PMID: 35087798 PMCID: PMC8787041 DOI: 10.3389/fbioe.2021.767256] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 12/15/2021] [Indexed: 12/16/2022] Open
Abstract
Besides osteoconductivity and a high degradation rate, mesoporous bioactive glasses (MBGs) are specific for their highly ordered channel structure and high specific surface area, making them suitable as drug and/or growth factor delivery systems. On the other hand, the mesoporous channel structure and MBG composition can have an effect on common cell evaluation assays, leading to inconclusive results. This effect is especially important when MBG is mixed in composite bioinks, together with cells. Additionally, the hydrogel component of the ink can influence the degradation of MBG, leading to different ion releases, which can additionally affect the analyses. Hence, our aim here was to show how the MBG structure and composition influence common cell viability and differentiation assays when calcium (Ca)- or magnesium (Mg)-containing glass is part of an alginate-based composite bioink. We suggested pre-labeling of cells with DiI prior to bioprinting and staining with calcein-AM to allow identification of metabolically active cells expressing signals in both green and red channels, allowing the use of fluorescence imaging for cell viability evaluations in the presence of high amounts (7 wt %) of MBGs. The release and uptake of ions during degradation of CaMBG and MgMBG were significantly changed by alginate in the composite bioinks, as confirmed by higher release and uptake from bulk glasses. Additionally, we detected a burst release of Mg2+ from composites only after 24 h of incubation. Furthermore, we demonstrated that released ions and the mesoporous channel structure affect the measurement of lactate dehydrogenase (LDH) and alkaline phosphatase activity (ALP) in bioprinted composite scaffolds. Measured LDH activity was significantly decreased in the presence of CaMBG. On the other hand, the presence of MgMBG induced increased signal measured for the ALP. Taken together, our findings show how composite bioinks containing MBGs can interfere with common analyses, obtaining misleading results.

Abstract
In prostate cancer, flavonoids possess a wide variety of anticancer effects, focused on the antioxidant/pro-oxidant activity, inactivation of the androgen receptor, cell cycle arrest, apoptosis induction, metastasis inhibition, among others. This current research investigated the antitumoral in vitro activity of Brachydin A (BrA), a dimeric flavonoid isolated from Fridericia platyphylla, in human castration-resistant prostate cancer DU145. It was compared BrA selective effects in tumor prostate DU145 cells with non-tumor prostate epithelial PNT2 cells. Cell viability experiments (resazurin, neutral red, MTT, and LDH release assays) showed that BrA was sevenfold more cytotoxic to tumor cells than non-tumor prostate cells, with IC50 values of 77.7 µM and 10.7 µM for PNT2 and DU145 cells, respectively. Furthermore, BrA induced necrosis and apoptosis (triple fluorescence staining assay) without interfering with oxidative stress (CM-H2DCFDA) in DU145 cells. Also, BrA (15.36 µM) reduced cell proliferation on clonogenic assay (DU145 cells) but no change in cell number and protein content was observed when cell growth curve assay was used. Wound healing and transwell assays were used for checking the effects of BrA on cell migration and invasion, and BrA impaired these processes in PNT2 (wound healing) and DU145 cells (transwell). Our results inspire further studies to test BrA as a novel chemotherapeutic drug and to evaluate its effects on drug-resistant metastatic cancer cells.

Abstract
Introduction:Ex vivo and in vitro diagnostics, such as interferon-γ (IFN-γ) release enzyme linked ImmunoSpot (ELISpot) and flow cytometry, are increasingly employed in the research and diagnostic setting for severe T-cell mediated hypersensitivity. Despite an increasing use of IFN-γ release ELISpot for drug causality assessment and utilization of a range of antimicrobial concentrations ex vivo, data regarding antimicrobial-associated cellular cytotoxicity and implications for assay performance remain scarcely described in the literature. Using the measurement of lactate dehydrogenase (LDH) and the 7-AAD cell viability staining, we aimed via an exploratory study, to determine the maximal antimicrobial concentrations required to preserve cell viability for commonly implicated antimicrobials in severe T-cell mediated hypersensitivity. Method: After an 18-h incubation of patient peripheral blood monocytes (PBMCs) and antimicrobials at varying drug concentrations, the cell cytotoxicity was measured in two ways. A colorimetric based assay that detects LDH activity and by flow cytometry using the 7-AAD cell viability staining. We used the PBMCs collected from three healthy control participants with no known history of adverse drug reaction and two patients with a rifampicin-associated drug reaction with eosinophilia and systemic symptoms (DRESS), confirmed on IFN-γ ELISpot assay. The PBMCs were stimulated for the investigated drugs at the previously published drug maximum concentration (Cmax), and concentrations 10- and 100-fold above. Results: In a human immunodeficiency virus (HIV) negative and a positive rifampicin-associated DRESS with positive ex vivo IFN-γ ELISpot assay, use of 10- and 100-fold Cmax drug concentrations decreased spot forming units/million cells by 32–100%, and this corresponded to cell cytotoxicity of more than 40 and 20% using an LDH assay and 7-AAD cell viability staining, respectively. The other antimicrobials (ceftriaxone, flucloxacillin, piperacillin/tazobactam, and isoniazid) tested in healthy controls showed similar dose-dependent increased cytotoxicity using the LDH assay, but cytotoxicity remained lower than 40% for all Cmax and 10-fold Cmax drug concentrations except flucloxacillin. All 100-fold Cmax concentrations resulted in cell death >40% (median 57%), except for isoniazid. 7-AAD cell viability staining also confirmed an increase in lymphocyte death in PBMCs incubated with 10-fold and 100-fold above Cmax for ceftriaxone, and flucloxacillin; however, piperacillin/tazobactam and isoniazid indicated no differences in percentages of viable lymphocytes across concentrations tested. Conclusion: The LDH cytotoxicity and 7-AAD cell viability staining techniques both demonstrate increased cell death corresponding to a loss in ELISpot sensitivity, with use of higher antimicrobial drug concentrations for ex vivo diagnostic IFN-γ ELISpot assays. For all the antimicrobials evaluated, the use of Cmax and 10-fold Cmax concentrations impacts cell viability and potentially affects ELISpot performance. These findings inform future approaches for ex vivo diagnostics such as IFN-γ release ELISpot.

Abstract
Allium species are medically important plants, rich in bioactive molecules with antitumoral properties. In this study, we aimed to investigate the molecular composition and in vitro anticancer activities of Allium willeanum Holmboe, an endemic Allium species of the island of Cyprus. GC-MS analysis of ethanolic extracts of A. willeanum H. bulb (AWB) showed bioactive molecules, octadecanoic acid 2-hydroxy-1-(hydroxymethyl)ethyl ester (21.99 %), hexadecanoic acid (20.42 %), pentadecanoic acid (9.19 %), 1,2-benzenedicarboxylic acid, diethyl ester (8.79 %), with known anticancer activities. AWB exerted significant reduction in mitochondria dependent metabolic activity as a measure of cell growth on MCF-7 (weakly metastatic) and MDA-MB-231 (strongly metastatic) human breast cancer (BCa) cell lines with a more prominent effect on highly metastatic BCa cells. Both trypan blue and lactate dehydrogenase (LDH) cytotoxicity assays quantitatively revealed that exposure to AWB extract significantly reduced cancer cell viability in both tested cell types. Differential activation of caspases in the tested cell lines indicated faster apoptotic activity on MDA-MB-231 cells compared to MCF-7. A significant reduction in cell motility was demonstrated upon AWB exposure of MCF-7 and MDA-MB-231 cells. AWB bioactive molecules collectively act on cancer cells to exert significant cytotoxic, apoptotic activities on both MCF-7 and MDA-MB-231 cells and significantly reduce their lateral motility, elucidating AWB as a promising agent to further be utilized in anticancer studies.

Abstract
Gastric cancer is the fifth most common malignancy worldwide. Serjania marginata Casar. (SM) displays anti-inflammatory properties and has been used to treat gastrointestinal disorders. In the current study, we examined whether the hydroethanolic extract of SM leaves exerted cytotoxic, mutagenic, and protective effects in non-tumor gastric epithelium cells (MNP01) and gastric adenocarcinoma cells (ACP02) in vitro and analyzed whether its action was selective. Initially, cell viability (MTT assay), cell cycle kinetics (flow cytometry), and cell proliferation (total protein content) were analyzed. In addition, genomic instability (cytokinesis-block micronucleus cytome assay), anti/pro-oxidant status (CM-H2 DCFDA probe), and transcriptional expression (RT-qPCR) of genes related to cell cycle, cell death, and antioxidant defense were also evaluated. The SM extract was cytotoxic toward MNP01 and ACP02 cells at concentrations greater than 300 and 100 μg·ml-1 , respectively, and decreased protein content only toward ACP02 cells at 200 μg ml-1 . In ACP02 cells, the SM extract at 100 μg·ml-1 associated with doxorubicin (DXR; 0.2 μg ml-1 ) clearly promoted cell cycle arrest at the G2/M phase. The extract alone was not mutagenic to either cell type and reversed DXR-induced DNA damage and H2 O2 -induced oxidative stress in MNP01 cells. The gene expression experiments showed that SM hydroethanolic extract exerts an antioxidant response via NFE2L2 activation in non-tumor gastric cells, and cell cycle arrest (G2/M) in ACP02 gastric cancer cells via the TP53 pathway. The selective action of SM indicates that it is a promising therapeutic agent to treat gastric diseases and merits further studies.

Abstract
Malignant melanoma is the major cause of skin cancer-related deaths. Surgery in combination with radiotherapy, immunotherapy or chemotherapy is used to eradicate cancer cells, however, this treatment option is limited by the tolerance of the surrounding healthy tissue. The extracts from Galenia africana have been shown to possess anti-cancer flavonoid compounds and can be a safer and cost-effective alternative treatment. The study aimed to compare the anti-proliferative effects of G. africana on human skin cells (HaCaT) and human malignant melanoma cells (A375). The cells were exposed to various concentrations of the G. africana extract at different times. In vitro assays were employed to determine cell viability and cytotoxicity. Hoechst 33342 staining was performed to observe the nuclear changes, including apoptosis. G. africana significantly reduced the cell viability of the A375 cells in a dose and time-dependent manner, while having no effect on the HaCaT cells. The A375 cells displayed nuclear condensation, brightly stained nuclei and nuclear fragmentation indicative of apoptosis. This suggests a clinical rationale for the use of G. africana as a potential anti-melanoma agent offering efficacy and low toxicity. This study provides new insights for future work on investigating the utilization of G. africana in malignant melanoma treatment.

Abstract
Mycoplasma bovis is an important cause of bovine mastitis in China and worldwide. We hypothesized that M. bovis damages bovine mammary epithelial cells (bMEC), with the degree of damage varying among field isolates. Our objective was to evaluate 2 novel sequence type (ST) field strains of M. bovis (ST172 and ST173) for their ability to induce oxidative stress, cytotoxicity, pathomorphological changes, and apoptosis in bMEC, as a model for pathogenesis of M. bovis-induced bovine mastitis. Cytotoxicity (as indicated by release of lactate dehydrogenase, LDH) from bMEC depended on multiplicity of infection (MOI), with a high MOI (1:1,000) being required to induce cytotoxicity. Morphological changes in bMEC, including shrinkage, loss of cell integrity, and heavy staining (hematoxylin and eosin) of cytoplasm were apparent 24 h after infection with ST172 or ST173 M. bovis, with more severe changes being induced by the latter strain. Adhesion and invasion assays both had curvilinear patterns, peaking 12 h after infection with MOI of 1:1,000. Both production of reactive oxygen species (ROS) and proportion of apoptotic cells increased with time after infection. Increased Bax/Bcl-2 ratios and activation of caspase-3 implied involvement of mitochondria-dependent pathways of apoptosis. Furthermore, intracellular ROS generation, apoptosis, and cleaved caspase-3 were mitigated by N-acetyl-l-cysteine, a ROS scavenger. Both interleukin (IL)-1β and IL-6 were significantly upregulated by ST172 and ST173 M. bovis, with little change in expression of tumor necrosis factor-α. One ST173 M. bovis isolate had the greatest cytotoxicity of all of our field isolates, with the highest LDH release, adhesion, invasion, ROS production, and apoptosis. In conclusion, our hypothesis was supported: M. bovis damaged bMEC by generating ROS and initiating a mitochondria-dependent pathway of apoptosis, with the degree of damage varying among field isolates. This study provided new knowledge regarding pathogenesis of M. bovis-induced bovine mastitis.

Abstract
UNLABELLED Brachydins (Br) A, B, and C are flavonoids extracted from Fridericia platyphylla (Cham.) L.G. Lohmann roots (synonym Arrabidaea brachypoda), whose extract previously exhibited cytotoxic and antitumor activity. In vitro cell culture of human prostate tumor cell line (PC-3) was used to determine cell viability as evidenced by MTT, neutral red, and LDH release using nine concentrations (0.24 to 30.72 µM) of each brachydin. A triple-fluorescent staining assay assessed the mechanism resulting in cell death. Genomic instability and protein expression were evaluated using comet assay and western blot analysis, respectively. The pro-oxidant status was analyzed using the5-(and-6)-chloromethyl-2',7'-dichlorodihydrofluorescein diacetate (CM-H2DCFDA) probe. The IC50 values for brachydins BrA, BrB, and BrC were 23.41, 4.28, and 4.44 µM, respectively, and all compounds induced apoptosis and necrosis. BrB and BrC increased p21 levels indicating a possible G1 cell cycle arrest. BrA (6 µM) and BrB (3.84 µM) decreased phospho-AKT (AKT serine/threonine kinase) expression, which also influenced cell cycle and proliferation.

Abstract
OBJECTIVE To examine the role of carvacrol in modulating PI3K/AKT signaling involved in human breast cancer pathogenesis using in vitro experimental model MCF-7 cells. METHODS MTT and lactate dehydrogenase assays were performed with cells treated with different doses of carvacrol (0-250 p mol/L) at different time points (24 and 48 h). The nuclear morphology was assessed in MCF-7 cells with propidium iodide (PI) and acridine orange/ethidium bromide (AO/EB) staining and analyzed by fluorescence microscopy. Events like cell cycle arrest, apoptosis was observed by flow cytometric analysis and expressions of p-Rb, cyclin D1, cyclin-dependent kinase 4 (CDK4), CDK6, Bax, Bcl-2, PI3K/p-AKT was analyzed by immunoblot. RESULTS Carvacrol significantly reduced cell viability with the half maximal inhibitory concentration value of 200 µmol/L at 24 and 48 h (P<0.05). importantly, there was a significant increase in the accumulation of the G0/G1 phase upon treatment with carvacrol in MCF-7 cells (P<0.05 or P<0.01). A remarkable decrease in protein expressions of p-Rb, cyclin D1, CDK4 and CDK6 denotes cell cycle arrest (P<0.05 or P<0.01). In addition, carvacrol treatment significantly inhibited PI3K/p-AKT protein expressions leading to induction of apoptosis mediated by decreased Bcl2 and increased Bax protein expressions. Further, Annexin V/PI staining by FACS analysis, dual staining by AO/EB and PI staining studies suggests induction of apoptosis by carvacrol through PI3K/Akt signaling pathway in MCF-7 cells. CONCLUSION Carvacrol significantly inhibited the breast cancer MCF-7 cell proliferation and induced apoptosis via suppressing PI3/AKT signaling pathway.

Abstract
Fridericia platyphylla (Cham.) L.G. Lohmann (FP) has cytotoxic, anti-inflammatory, and analgesic properties. We aimed to characterize the cytotoxic and antiproliferative effects of FP extract on normal (GAS) and tumor-derived (ACP02 and HepG2) cell lines. The effective concentrations (EC50s) by tetrazolium bromide assay (MTT) were 56.16, 43.68, and 42.57 µg mL−1 and 69.38, 41.73, and 52.39 µg mL−1 by neutral red assay for GAS, ACP02, and HepG2 cells, respectively. The extract decreased nuclear division indices, which was not reflected in cell proliferation curves. Flow cytometric analyses showed that even 30 µg mL−1 extract (shown to be noncytotoxic by MTT assay) increased the sub-G1 population, indicating cell death due to apoptosis and necrosis. A cytokinesis-block micronucleus cytome assay showed that 30 µg mL−1 of the extract increased the frequency of nuclear buds in tumor cells. Real-time quantitative polymerase chain reaction showed CCND1 upregulation in doxorubicin-treated GAS cells and BCL-XL, BIRC5, and MET downregulation in 5 or 30 µg mL−1 in FP extract-treated ACP02 cells. In conclusion, FP extract modulated apoptosis- and cell cycle-related genes and presented selective cytotoxicity toward tumor cells that deserves further investigation by testing other cell types. Our results demonstrated that even medicinal plants exert adverse effects depending on the extract concentrations used and tissues investigated.

Abstract
BACKGROUND The plant-derived terpenoid, alpha-pinene is a bicyclic monoterpene potentially useful for the treatment of various diseases which also includes cancer and its types. The present investigation is about finding the anticancer activity of the alpha-pinene extracted from the leaves of Boswellia dalzielii over the PA-1 cancer cells of the human ovary. MATERIAL AND METHODS The cytotoxic activity of the alpha-pinene was evaluated using MTT and LDH assays which indicated that alpha-pinene could induce cytotoxicity in cancer-causing cells in the ovary. The consequences of alpha-pinene on the cell sequence regulation were determined by the staining technique using propidium iodide (PI) followed with flow cytometry. RESULTS The cell cycle distribution analysis showed that alpha-pinene inhibit the cycle progression from G₂ to M phase. In addition, apoptosis analysis is done through the double staining investigation using Annexin V-FITC/PI to analyze the controlled growth of alpha-pinene which is associated with the apoptosis. Caspase-3 a crucial enzyme involved in apoptosis was markedly increased in the a-pinene treated PA-1 cells. The apoptosis results reveal, that the cancer cells at the human ovary with alpha-pinene induces the significant populations of apoptotic cells. CONCLUSIONS Overall, alpha-pinene may exert anticancer effects in PA-1 cells by promoting cytotoxicity, suppression of cell sequence progression along with the programmed cell death.

Abstract
BACKGROUND UV filters should be determined a strict toxicological safety prior to approval. Homosalate (HMS) is one of the most widely used organic UV filter. HMS accumulates in aquatic biota ecosystems and humans through the food chain; therefore, it is important to consider the effects on health and know its mechanisms of action. AIMS The study aimed to evaluate the cytotoxic and genotoxic effects of HMS in MCF-7 cell line. METHODS Cell viability was examined by the 3-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide (MTT) and cell membrane integrity by the lactate dehydrogenase release assays (LDH), and genotoxicity by using the micronucleus test at 250, 500, 750, 1000, 1500, and 2000 µM concentrations with the human breast cell line MCF-7. RESULTS Homosalate affected the cell viability dose-dependently at a concentrations of above 1000 µM. Micronucleus formation was significantly induced at 750 and 1000 µM within 24 hours due to an increase in cytostatic effect, the cell viability of HMS decreased to 57% at a concentration of 2000 µM, and a sufficient number of binucleated cells could not be obtained to count. Homosalate was also clastogenic when the cells were incubated at cytotoxic concentrations. CONCLUSION These results suggest that homosalate can be considered as a cytotoxic and genotoxic substance.

Abstract
The integrity and normal function of the small intestinal epithelium depends critically on the rapid renewal of epithelial cells from basal stem cells. The intensive proliferation that fuels this self-renewal process is confined to the intestinal crypts. Establishment of suitable protocols for crypt isolation and culture is pivotal for the studies of intestinal self-renewal mechanisms. In this study, chicken small intestinal crypts were isolated, purified, and further cultured in a Matrigel 3-D culture system. The growth factor concentration assay on the fourth d of culture showed that Group C (50 ng/mL epidermal growth factor (EGF), 100 ng/mL Noggin, and 500 ng/mL R-spondin 1) supplement in culture medium could significantly enlarge the diameter of organoids when compared with Group A (5 ng/mL EGF, 10 ng/mL Noggin, 50 ng/mL, and R-spondin 1) and Group B (10 ng/mL EGF, 20 ng/mL Noggin, and 100 ng/mL R-spondin 1) by 188.4% (P = 0.026) and 176.9% (P = 0.034), respectively. Transmission electron microscopy, neutral red staining, and 5-ethynyl-2΄-deoxyuridine incorporation demonstrated the integrated structure, high viability, and proliferative activity in cultured chicken intestinal organoids. In addition, intestinal stem cell marker genes (Olfm4, Znrf3, Hopx, and Lgr5) also could be detected in cultured intestinal organoids. Furthermore, CHIR99021 (a glycogen synthase kinase 3β inhibitor) could enhance the expression of Olfm4, Znrf3, Hopx, and Lgr5 by 750% (P = 0.001), 467% (P < 0.001), 450% (P < 0.001), and 333% (P = 0.008), respectively, indicating the responsiveness of the cultured chicken intestinal organoids to exogenous stimulus. This study modified a murine culture model and optimized it to provide a chicken intestinal organoid model for use as a physiological or pathological research platform in vitro.

Abstract
Pouteria ramiflora (Mart.) Radlk., popularly known as curriola, is commonly used in Brazil as medicinal plant to treat worm infections, dysentery, pain, inflammation, hyperlipidemia, and obesity. At present the safety of this extract when used therapeutically in human remains to be determined. Thus, the aim of this study was to examine cytotoxicity, antiproliferative, and antimutagenic actions of this extract. The hydroalcoholic extract from P. ramiflora leaves consisted of flavonoids identified and quantified as myricetin-3-O-β-D-galactopyranoside (13.55 mg/g) and myricetin-3-O-α-L-rhamnopyranoside (9.61 mg/g). The extract exhibited cytotoxicity at concentrations higher than 1.5 µg/ml in human hepatocarcinoma (HepG2)and 2.5 µg/ml in non-tumoral primary gastric (GAS) cells using the MTT assay, and at concentrations higher than 3 µg/ml in HepG2 and 3.5 µg/ml in GAS cells by the neutral red assay. The extract did not show antiproliferative effect as evidenced by the nuclear division index (NDI). However, in the presence of benzo[a]pyrene (BaP) (positive control), an enhanced cytostatic effect in the NDI and flow cytometry was noted. It is of interest that when the extract was co-incubated with BaP a significant decrease in DNA damage was observed indicating an antimutagenic action. This protective effect might be attributed to myricetin and gallic acid found in P. ramiflora extract. The low cytotoxicity action and protective effect observed in the present study encourage further studies regarding other biological effects of P. ramiflora, as well as its potential use as a chemopreventive agent.

Abstract
Cancer is a major public health problem around the globe. This disorder is affected by alterations in multiple physiological processes, and oxidative stress has been etiologically implicated in its pathogenesis. Glioblastoma (GBM) is considered the most common and aggressive brain tumor with poor prognosis despite recent improvements in surgical, radiation, and chemotherapy-based treatment approaches. The purpose of this study was to evaluate antitumor activity from Mentha crispa essential oil (MCEO), its major constituent rotundifolone (ROT), and a series of six analogues on the human U87MG glioblastoma cell line. Cytotoxic effects of the compounds on the human U87MG-GBM cell line were assessed using in vitro cell viability and oxidative and molecular genetic assays. In addition, biosafety assessment tests were performed on cultured human blood cells. Our findings revealed that MCEO, 1,2-perillaldehyde epoxide (EPER1), and perillaldehyde (PALD) were the most cytotoxic compounds against U87MG cells, with IC50 values of 16.263, 15.087, and 14.888 μg/mL, respectively. Further, these compounds increased the expressions of BRAF, EGFR, KRAS, NFκB1, NFκB1A, NFκB2, PIK3CA, PIK3R, PTEN, and TP53 genes at different degrees and decreased the expression of some genes such as AKT1, AKT2, FOS, and RAF1. Finally, treatment with MCEO, EPER1, and PALD did not lead to genotoxic damage in blood cells. Taken together, our findings reveal antiproliferative potential of MCEO, its major component ROT, and its tested analogues. Some of these chemical analogues may be useful as prototypes for the development of novel chemotherapeutic agents for treating human brain cancer and/or other cancers due to their promising activities as well as nonmutagenic property and safety.

Abstract
Colorectal carcinoma is one of the most common cancers in adults. As chemotherapy, the first-choice treatment for colorectal carcinoma, is often infeasible due to acquired tumor resistance and several adverse effects, it is important to discover and explore new molecules with better therapeutic action. Snake venom toxins have shown promising results with high cytotoxicity against tumor cells, but their mechanisms of action remain unclear. Here we examined how BjussuLAAO-II, an L-amino acid oxidase isolated from Bothrops jararacussu snake venom, exerts cytotoxicity towards colorectal adenocarcinoma human cells (Caco-2) and human umbilical vein endothelial cell line (HUVEC). A 24-h treatment with BjussuLAAO-II at 0.25 - 5.00 μg/mL diminished cell viability by decreasing (i) mitochondrial activity, assessed by reduction of 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide and resazurin; (ii) the activity of acid phosphatases; and (iii) lysosomal function, assessed by neutral red uptake. BjussuLAAO-II also increased intracellular levels of reactive oxygen species and DNA damage, as assessed by fluorescence and the comet assay, respectively. BjussuLAAO-II altered the expression of cell proliferation-related genes, as determined by RT-qPCR: it elevated the expression of the inflammatory cytokine genes TNF and IL6, and lowered the expression of the apoptotic-related genes BAX, BCL2, and RELA. Therefore, BjussuLAAO-II induces Caco-2 cells death by acting on multiple intracellular targets, providing important data for further studies to assess whether these effects are seen in both tumor and normal cells, with the aim of selecting this drug for possible therapeutic purposes in the future.
