Full textBiological screens test large sets of experimental conditions with respect to their specific biological effect on living systems. Technical and computational progresses have made it possible to perform such screens at a large scale - up to hundreds of thousands of experiments. Live cell imaging is an excellent tool to study in detail the consequences of chemical perturbation on a given biological process. However, the analysis of live cell screens demands the combination of robust computer vision methods, efficient statistical methods for the detection of significant effects and robust procedures for quality control. This thesis addresses these challenges by developing analytical methods for the analysis of High Throughput time-lapse microscopy screening data. The developed frameworks are applied to publicly available HCS data, demonstrating their applicability and the benefits of HCS data remining. The first multivariate workflow for the study of single cell motility in such large-scale data is detailed in Chapter 2. Chapter 3 presents this workflow application to previously published data, and the development of a new distance for drug target inference by in silico comparisons of parallel siRNA and drug screens. Finally, chapter 4 presents a complete methodological pipeline for performing HT time-lapse screens in Environmental Toxicology

Full textCurrently, chemical safety assessment mostly relies on results obtained in in vivo studies performed in laboratory animals. However, these studies are costly in term of time, money and animals used and therefore not adapted for the evaluation of thousands of compounds. In order to rapidly screen compounds for their potential toxicity and prioritize them for further testing, alternative solutions are envisioned such as in vitro assays and computational predictive models. The objective of this thesis is to evaluate how the public data from ToxCast and ToxRefDB can allow the construction of this type of models in order to predict in vivo effects induced by compounds, only based on their chemical structure. To do so, after data pre-processing, we first focus on the prediction of in vitro bioactivity from chemical structure and then on the prediction of in vivo effects from in vitro bioactivity data. For the in vitro bioactivity prediction, we build and test various models based on compounds’ chemical structure descriptors. Since learning data are highly imbalanced in favor of non-toxic compounds, we test a data augmentation technique and show that it improves models’ performances. We also perform a largescale study to predict hundreds of in vitro assays from ToxCast and show that the stacked generalization ensemble method leads to reliable models when used on their applicability domain. For the in vivo effects prediction, we evaluate the link between results from in vitro assays targeting pathways known to induce endocrine effects and in vivo effects observed in endocrine organs during longterm studies. We highlight that, unexpectedly, these assays are not predictive of the in vivo effects, which raises the crucial question of the relevance of in vitro assays. We thus hypothesize that the selection of assays able to predict in vivo effects should be based on complementary information such as, in particular, mechanistic data

Full textThe traditional paradigm for human risk assessment of chemicals relies heavily on studies in laboratory animals. However, in vivo studies are lengthy, costly, raise ethical concerns and are not considered fully relevant to human physiology. In response, regulators are encouraging the adoption of non-animal alternatives for risk assessment based on human cell cultures. As part of this shift, several New Approach Methods (NAMs) are being developed to replace animal testing. In addition, a framework known as Next Generation Risk Assessment (NGRA) is being established to integrate these new methods into chemical risk assessment. This thesis focuses on one NAM, an in vitro cell morphological profiling assay called Cell Painting. This assay generates detailed images of cells exposed to chemical treatments. Morphological features are extracted from the cell images to generate profiles that describe the average cell morphology at a given compound concentration. The morphological profiles were applied in two key areas. The first application aimed to predict the acute oral toxicity of chemical compounds in rats using a read-across approach with a K-nearest neighbor classifier. The results demonstrated that morphological profiles could offer valuable insights for predicting oral acute toxicity. Unlike chemical structure-based read-across methods, which are confined to the chemical space of compounds with known toxicity, Cell Painting profiles can explore new chemical spaces. Additionally, combining Cell Painting morphological profiles with chemical structure information was shown to improve the accuracy of toxicity prediction. The second application used morphological profiles to determine an in vitro point of departure (POD), the concentration at which a morphological change begins to occur. Various methods for determining in vitro POD were compared. Toxicokinetic models were then used to extrapolate an Administered Equivalent Dose (AED), from the POD. These AEDs were then compared with established in vivo dose levels such as the No Observed Adverse Effect Level (NOAEL), and the Acceptable Daily Intake (ADI). The results showed that most of the AEDs were within a 10-fold range of the known in vivo doses. These findings provide a baseline for benchmarking alternative methods to determine the POD using different techniques, cell lines, or assays, and to extrapolate in vivo doses using different toxicokinetic models. These two applications have demonstrated the potential of Cell Painting in toxicology. Further research is needed to explore different cell lines and machine learning algorithms for image analysis. Combining Cell Painting results across different cell systems, along with results from other in vitro assays using a weight of evidence approach, could lead to a more comprehensive assessment of chemical risks. Currently, these two applications can assist in early-stage toxicology to select candidates with better toxicological profiles. Additionally, Cell Painting could play a role in Next Generation Risk Assessment (NGRA) by generating hypotheses about potential acute oral toxicity and providing initial estimates of safe in vivo doses

Full textPattern discovery is an important field of Knowledge Discovery in Databases.This work deals with the extraction of minimal emerging patterns. We propose a new efficientmethod which allows to extract the minimal emerging patterns with or without constraint ofsupport ; unlike existing methods that typically extract the most supported minimal emergentpatterns, at the risk of missing interesting but less supported patterns. Moreover, our methodtakes into account the absence of attribute that brings a new interesting knowledge.Considering the rules associated with emerging patterns highly supported as prototype rules,we have experimentally shown that this set of rules has good confidence on the covered objectsbut unfortunately does not cover a significant part of the objects ; which is a disavadntagefor their use in classification. We propose a prototype-based selection method that improvesthe coverage of the set of the prototype rules without a significative loss on their confidence.We apply our prototype-based selection method to a chemical data relating to the aquaticenvironment : Aquatox. In a classification context, it allows chemists to better explain theclassification of molecules, which, without this method of selection, would be predicted by theuse of a default rule
