Abstract
Animal models are considered prime study models for inhalation-like toxicity assessment. However, in light of animal experimentation reduction (3Rs), we developed and investigated an alternative in vitro method to study systemic-like responses to inhalation-like exposures. A coculture platform was established to emulate inter-organ crosstalks between a pulmonary barrier, which constitutes the route of entry of inhaled compounds, and the liver, which plays a major role in xenobiotic metabolism. Both compartments (Calu-3 insert and HepG2/C3A biochip) were jointly cultured in a dynamically-stimulated environment for 72 h. The present model was characterized using acetaminophen (APAP), a well-documented hepatotoxicant, to visibly assess the passage and circulation of a xenobiotic through the device. Based on viability and functionality parameters the coculture model showed that the bronchial barrier and the liver biochip can successfully be maintained viable and function in a dynamic coculture setting for 3 days. In a stress-induced environment, present results reported that the coculture model emulated active and functional in vitro crosstalk that seemingly was responsive to xenobiotic exposure doses. The hepatic and bronchial cellular responses to xenobiotic exposure were modified in the coculture setting as they displayed earlier and stronger detoxification processes, highlighting active and functional organ crosstalk between both compartments.

Abstract
IMPACT STATEMENT Three dimensional in vitro cell culture systems better reflect the native structural architecture of tissues and are attractive to investigate cancer cell sensitivity to drugs. We have developed and compared several metastatic melanoma (MM) models cultured as a monolayer (2D) and cocultured on three dimensional (3D) dermal equivalents with fibroblasts to better unravel factors modulating cell sensitivity to vemurafenib, a BRAF inhibitor. The heterotypic 3D melanoma model we have established summarizes paracrine signalization by stromal cells and type I collagen matrix, mimicking the natural microenvironment of cutaneous MM, and allows for the identification of potent sensitive melanoma cells to the drug. This model could be a powerful tool for predicting drug efficiency.

Abstract
Sugar-based surfactants present surface-active properties and relatively low cytotoxicity. They are often considered as safe alternatives to currently used surfactants in cosmetic industries. In this study, four sugar-based surfactants, each with an eight carbon alkyl chain bound to a glucose or a maltose headgroup through an amide linkage, were synthesized and compared to two standard surfactants. The cytotoxic and irritant effects of surfactants were evaluated using two biologically relevant models: 3D dermal model (mouse fibroblasts embedded in collagen gel) and reconstituted human epidermis (RHE, multi-layered human keratinocytes). Results show that three synthesized surfactants possess lower cytotoxicity compared to standard surfactants as demonstrated in the 3D dermal model. Moreover, the IC50s of surfactants against the 3D dermal model are higher than IC50s obtained with the 2D dermal model (monolayer mouse fibroblasts). Both synthesized and standard surfactants show no irritant effects after 48h of topical application on RHE. Throughout the study, we demonstrate the difficulty to link the physico-chemical properties of surfactants and their cytotoxicity in complex models. More importantly, our data suggest that, prior to in vivo tests, a complete understanding of surfactant cytotoxicity or irritancy potential requires a combination of cellular and tissue models.

Abstract
As transforming growth factor (TGF)-β inducible early gene-1 is highly expressed in skeletal muscle, the effect of TIEG1 gene deletion on the passive mechanical properties of slow and fast twitch muscle fibers was analyzed. Twenty five muscle fibers were harvested from soleus (Sol) and extensor digitorum longus (EDL) muscles from TIEG1-/- (N = 5) and control (N = 5) mice. Mechanical tests were performed on fibers and the dynamic and static stresses were measured. A viscoelastic Hill model of 3rd order was used to fit the experimental relaxation test data. In parallel, immunohistochemical analyses were performed on three serial transverse sections to detect the myosin isoforms within the slow and fast muscles. The percentage and the mean cross sectional area of each fiber type were calculated. These tests revealed a significant increase in the mechanical stress properties for the TIEG1-/- Sol fibers while a significant decrease appeared for the TIEG1-/- EDL fibers. Hill model tracked the shape of the experimental relaxation curve for both genotypes and both fiber types. Immunohistochemical results showed hypertrophy of all fiber types for TIEG1-/- muscles with an increase in the percentage of glycolytic fibers (IIX, and IIB) and a decrease of oxidative fibers (I, and IIA). This study has provided new insights into the role of TIEG1, known as KLF10, in the functional (SoltypeI: more resistant, EDLtypeIIB: less resistant) and morphological (glycolytic hypertrophy) properties of fast and slow twitch skeletal muscles. Further investigation at the cellular level will better reveal the role of the TIEG1 gene in skeletal muscle tissue.

Abstract
Surfactants derived from the biorefinery process can present interesting surface-active properties, low cytotoxicity, high biocompatibility and biodegradability. They are therefore considered as potential sustainable substitutes to currently used petroleum-based surfactants. To better understand and anticipate their performances, structure-property relationships need to be carefully investigated. For this reason, we applied a multidisciplinary approach to systematically explore the effect of subtle structural variations on both physico-chemical properties and biological effects. Four sugar-based surfactants, each with an eight carbon alkyl chain bound to a glucose or maltose head group by an amide linkage, were synthesized and evaluated together along with two commercially available standard surfactants. Physico-chemical properties including solubility, Krafft point, surface-tension lowering and critical micellar concentration (CMC) in water and biological medium were explored. Cytotoxicity evaluation by measuring proliferation index and metabolic activity against dermal fibroblasts showed that all surfactants studied may induce cell death at low concentrations (below their CMC). Results revealed significant differences in both physico-chemical properties and cytotoxic effects depending on molecule structural features, such as the position of the linkage on the sugar head-group, or the orientation of the amide linkage. Furthermore, the cytotoxic response increased with the reduction of surfactant CMC. This study underscores the relevance of a methodical and multidisciplinary approach that enables the consideration of surfactant solution properties when applied to biological materials. Overall, our results will contribute to a better understanding of the concomitant impact of surfactant structure at physico-chemical and biological levels.

Abstract
Recent studies have pointed out the preventive role of beetroot extracts against cancers and their cytotoxic activity on cancer cells. Among many different natural compounds, these extracts contained betanin and its stereoisomer isobetanin, which belongs to the betalain group of highly bioavailable antioxidants. However, a precise identification of the molecules responsible for this tumor-inhibitory effect was still required. We isolated a betanin/isobetanin concentrate from fresh beetroots, corresponding to the highest purified betanin extract used for studying anticancer activities of these molecules. The cytotoxicity of this betanin-enriched extract was then characterized on cancer and normal cells and we highlighted the death signalling pathways involved. Betanin/isobetanin concentrate significantly decreased cancer cell proliferation and viability. Particularly in MCF-7-treated cells, the expressions of apoptosis-related proteins (Bad, TRAILR4, FAS, p53) were strongly increased and the mitochondrial membrane potential was altered, demonstrating the involvement of both intrinsic and extrinsic apoptotic pathways. Autophagosome vesicles in MCF-7-treated cells were observed, also suggesting autophagic cell death upon betanin/isobetanin treatment. Importantly, the betanin-enriched extract had no obvious effect towards normal cell lines. Our data bring new insight to consider the betanin/isobetanin mix as therapeutic anticancer compound, alone or in combination with classical chemotherapeutic drugs, especially in functional p53 tumors.

Abstract
Epidermal Growth Factor Receptor (EGFR) is an important target of anticancer therapy. Nowadays, the search for new molecules inhibiting this receptor is turning toward natural substances. One of the most promising natural compounds that have shown an anti-EGFR activity is curcumin, a polyphenol found in turmeric. Its effect on the receptor kinase activity and on the receptor autophosphorylation has been already described, but the mechanism of how curcumin interacts with EGFR is not fully elucidated. We demonstrate that the mode of action of curcumin is dual. This polyphenol is able to inhibit directly but partially the enzymatic activity of the EGFR intracellular domain. The present work shows that curcumin also influences the cell membrane environment of EGFR. Using biomimetic membrane models, we show that curcumin insertion into the lipid bilayer leads to its rigidification. Single particle tracking analyses performed in the membrane of A431 cancer cells confirmed that this effect of curcumin on the membrane slows down the receptor diffusion. This is likely to affect the receptor dimerization and, in turn, its activation.

Since a few years, the acoustic sensing of whole cell is the focus of increasing interest for monitoring the cytoskeletal cellular response to morphological modulators. We aimed at illustrating the potentialities of the quartz crystal microbalance with dissipation (QCM-D) technique for the real-time detection of the earliest morphological changes that occur at the cell-substrate interface during programmed cell death. Human breast cancer cells (MCF-7) grown on serum protein-coated gold sensors were placed in dynamic conditions under a continuous medium flow. The mass and viscoelasticity changes of the cells were tracked by monitoring the frequency and dissipation shifts during the first 4h of cell exposure to staurosporine, a well-known apoptosis inducer. We have identified a QCM-D signature characteristic of morphological modifications and cell detachment from the sensing surface that are related to the pro-apoptotic treatment. In particular, for low staurosporine doses below 1 µM, we showed that recording the dissipation shift allows to detect an early cell response which is undetectable after the same duration by the classical analytical techniques in cell biology. Furthermore, this sensing method allows quantifying the efficiency of the drug effect in less than 4h without requiring labeling and without interfering in the system, thus preventing any loss of information. In the actual context of targeted cancer therapy development, we believe that these results bring new insights in favor of the use of the non invasive QCM-D technique for quickly probing the cancer cell sensitivity to death inducer drugs.

Abstract
In the context of rapid development of nanoparticles (NPs) for industrial applications, the question of their toxicity and biological effects must be considered. In this work, we have assessed the influence of titanium dioxide NPs on the adhesion and spreading of MC-3T3 pre-osteoblasts by using a cell subclone that does not produce its own extracellular matrix. Petri dishes were coated with the important adhesion protein fibronectin (Fn). By incubating these Fn-coated surfaces with different amounts of TiO(2) NPs, we have shown that the adhesion of pre-osteoblasts is disturbed, with an important decrease in the number of adherent cells (from 40 to 75% depending upon the concentration and type of NPs). Petri-dish surfaces were analyzed with environmental scanning electron microscropy (ESEM), with images showing that TiO(2) NP aggregates are bound to the layer of adsorbed Fn molecules. The cells cultured on these Fn/NP surfaces adopted an irregular shape and an aberrant organization of actin cytoskeleton, as revealed by fluorescence microscopy. Most importantly, these results, taken together, have revealed that the actin cytoskeleton forms abnormal aggregates, even on top of the nucleus, that coincide with the presence of large aggregates of NPs on top of cells. On the basis of these observations, we propose that some Fn molecules are able to desorb from the Petri dish surface to coat TiO(2) NPs. Fn/NP complexes are not attached firmly enough on the surface to allow for normal cell adhesion/spreading and the development of tense actin fibers. These results stress the paramount need for the assessment of the toxicology of NPs, with special attention to their interactions with biomolecules.

Abstract
There is a bundle of proofs suggesting that some industrial nanoparticles (NPs) can provoke diseases and pollute the environment durably. However, these issues still remain controversial. In the biomedical field, TiO(2) NPs were recently proposed to serve as fillers in polymeric materials to improve bone prostheses and scaffolds. Submicrometer TiO(2) particles could also result from wear debris of prostheses. Thus, it appears to be of the highest importance to elucidate the effects of well-characterized TiO(2) NPs on the behaviour of osteoblasts. In this work, we have measured the toxicity of anatase TiO(2) NPs with two different cell types, on L929 fibroblasts and for the first time on MC-3T3 pre-osteoblasts, with the aim to determine the level of cellular toxicity and inflammation. Our results clearly show that these NPs provoke different dose-response effects, with the pre-osteoblasts being much more sensitive than fibroblasts. Furthermore, we observed that anatase TiO(2) NPs had no effect on cell adhesion. By contrast, both cell types had their morphology and LDH release modified in the presence of NPs. Their DNA was also found to be fragmented as analyzed by quantifying the sub-G1 cell population with flow cytometry. By measuring the production of IL-6 and TNF-α proinflammatory cytokines, we have shown that TNF-α was never produced and that MC-3T3 cells were secreting IL-6. Most importantly, our results highlight the necessity of evaluating the toxicity of prostheses wear debris, and of NP coatings of medical implants, to determine if they can possibly provoke inflammation and inhibit bone reconstruction.

Abstract
The surface of an implant device can be modified by immobilizing biological molecules on it to improve its integration into the host tissue. We have previously demonstrated that enzymatically tailored plant pectins are promising nanocoatings for biomaterials. This study investigates whether a coating of modified hairy region (rhamnogalacturonan-I) from apple pectin (MHR-alpha) which has anti-adhesive properties can inhibit the generation of inflammatory mediators by lipopolysaccharide (LPS)-activated macrophages. For that purpose, J774.2 murine macrophages were cultured for 24h on MHR-alpha-coated Petri dishes and tissue culture polystyrene controls, with and without LPS. Cell morphology, cell growth, nitrite and TNF-alpha secretion were studied. The results indicate that MHR-alpha coating inhibits the LPS-induced activation of macrophages.

Abstract
There is evidence that the shape of cells and their contact with a matrix direct the growth and the differentiation of both normal and cancer cells. Cells in 3D culture resemble the in vivo situation more closely than do those in conventional 2D cultures. We have studied the interactions and functions of B16F10 mouse melanoma cells, which spread and grow well on tissue culture polystyrene (tPS), when they were made to aggregate on cellulose-coated Petri dishes (CEL). This aggregation of melanoma cells on CEL was Ca2+ dependent and mediated by N-cadherins. The levels of N-cadherin and beta-catenin transcripts in cells cultured on CEL and tPS were similar, but those on CEL contained less beta-catenin protein. Immunoprecipitation and immunostaining showed that both N-cadherins and beta-catenins were present at the membranes of cells on CEL. Cells proliferated significantly more slowly after 48 h on CEL and the cellulose coating caused most of them to arrest in G1. We also compared the melanin contents and tyrosinase activity of cells on CEL and controls grown on tPS. Melanogenesis was induced in cells aggregated on CEL. A cellulose substrate thus appears to be an outstanding tool for studying cell-cell interactions and cell functions in 3D cultures.

Abstract
p53-Related genes, p73 and p63, encode 2 classes of proteins, TA-p73/p63 and DeltaN-p73/p63. TA-p73/p63 demonstrate p53-like properties including gene transactivation and cell death promotion, whereas DeltaN-p73/p63 lack these p53-like functions. Although p53-deficient cancer cells are often less responsive to chemotherapy, they are not completely drug resistant, suggesting that other apoptotic pathways are at work. Here, we compared for the first time to our knowledge p73 and p63 activation in various breast cancer (BC) cell lines after Adriamycin (ADR) treatment, an agent considered as mandatory in breast cancer chemotherapy. Our study was carried out using 1 p53-proficient BC cell line (MCF7 cells) and 3 BC cell lines deficient in p53 response (MCF7/ADR(IGR), MDA-MB157 and T47D) after ADR-induced genotoxic stress. We report that in cells with no p53 response after ADR treatment, TAp73, but not TAp63 or DeltaN-p73/p63, may replace p53 in triggering not only apoptosis but also cell cycle arrest or DNA repair effectors such as p21, GADD45, 14-3-3sigma and p53R2. We also demonstrate that TAp73 siRNA inhibits the accumulation of TAp73 in response to ADR treatment in MDA-MB157 cells and confers protection against ADR. ADR-induced downregulation of the DeltaNp73 isoform in the T47D cell line with nonfunctional mutant p53 further supports anti-apoptotic function of the isoform antagonistic to both p53 and TA-p73/p63. Exogenous TAp73 and DeltaNp73 overexpression in p53-response-deficient cell lines further confirms these results. cDNA microarray techniques demonstrated that the cellular response induced by p73 during ADR treatment could involve specific genes.

Abstract
As the antimitotic agent vincristine (VCR) has been reported to induce a weak p53 response in some studies, we hypothesised that p73 and p63, the recently described p53 homologues, may replace p53 in triggering apoptosis or cell cycle arrest effectors in VCR-treated cell lines. To address this issue, we measured p53, p73 and p63 mRNA and protein levels in two VCR-treated breast cancer cell lines, one p53-proficient (MCF7) and the other p53-deficient (MDA-MB157). We found an increase of p53 mRNA and protein levels in VCR-treated MCF7 cells, while, as expected, no p53 protein was detected in VCR-treated MDA-MB157 cells. Surprisingly, the p73 mRNA and protein expression levels decreased in both cell lines during VCR treatment, whereas p63 protein levels remained unchanged. In both cell lines, up-regulations of the canonical p53-target genes, such as p21 and GADD45, were consistently observed. We conclude that, in response to VCR treatment: (1) p53 is markedly induced in MCF7 cells, with the same extent than after DNA damaging drugs treatments; and (2) p63 is not involved, while p73 expression is down-regulated regardless of the p53 status of the cell lines. Our results therefore suggest the involvement of a fourth member of the p53 gene family, or the use of another pathway able to trigger canonical p53-target genes in response to VCR in p53-deficient cells.

Abstract
P73, a p53-homologue gene, has been studied for its possible role in head and neck squamous epithelium (HNSE) differentiation and carcinogenesis. P73 RNA and protein were analysed in 50 biopsies, including well- and moderately-differentiated carcinomas, and 21 matched normal adjacent tissues. P73 immunohistochemical analyses revealed intense p73 nuclear staining in basal and parabasal cells of normal squamous epithelium, in contrast with complete absence of staining in the more superficial cell layers. Moderately-differentiated carcinomas demonstrated homogeneous and diffuse staining in all tumour cells, while only basal cells were stained in well-differentiated carcinomas as in normal tissue. No correlation was observed between p73 and p53 protein expression. Immunostaining for p63, another p53-related protein previously described as being involved in HNSE morphogenesis and overexpressed in head and neck squamous cell carcinomas (HNSCC), was found to be similar to p73 labelling in carcinomas, but spread to the more differentiated layers in normal epithelium. Biallelic expression of p73 was found in tumours as well as in matched normal tissues. Comparison of p73 transcript levels between tumours and normal tissues showed decreased mRNA expression in 5/17 (30%) tumours independently of the differentiation status. Mutation and loss of heterozygosity analyses of the p73 gene revealed wild type status and no deletion. Our results strongly suggest that: (i) p73 is associated with homeostasis and control of differentiation of head and neck squamous epithelium probably in concert with p53 and p63; (ii) down-regulation of p73 expression could participate in HNSE carcinogenesis.

Abstract
The p73 gene is a p53 homologue located at 1p36-33, a region submitted to deletions in breast cancer (BC) and putatively imprinted. To study whether p73 was associated with breast carcinogenesis, loss of heterozygosity (LOH), allele expression and transcript levels were assessed in 59 BC, including 39 BC presenting no inflammatory symptoms (NBC) and 20 inflammatory BC (IBC). IBC is a rare but aggressive form of cancer with a very poor prognosis. Normal breast epithelium (BE) and lymphocytes from patients were used as controls. StyI polymorphism generating GC and/or AT alleles was used to select 22 heterozygous patients. p73 LOH was significantly higher in IBC than in NBC [five of eight cases (62%) versus two of 14 cases (14%); Fisher's exact test, P=0.05]. p73 was biallelically expressed in all BE. In contrast, 12 of 16 (75%) BC were monoallelically expressed, showing that allele silencing was significantly associated with breast carcinogenesis (P=0.012), AT being the preferential silent allele (10 out of 12 tumours). p73 mRNA levels in NBC and IBC were two- and threefold lower than in BE, respectively, suggesting that decreased expression could be related to tumour aggressiveness. In conclusion, LOH, allele silencing and decreased expression of the p73 gene may play a role in breast carcinogenesis.
