چکیده

Alternative splicing is a key process in post-transcriptional regulation, by which several kinds of mature RNA can be obtained from the same premessenger RNA. The resulting combinatorial complexity contributes to biological diversity, especially in the case of the human immunode ciency virus HIV-1. Using a constraint programming approach, we develop a model of the alternative splicing regulation in HIV-1. Our model integrates di erent scales (single site vs. multiple sites), and thus allows us to exploit several types of experimental data available to us.

Il permet d'obtenir di érents ARN matures provenant du même ARN prémessager. La complexité combinatoire qui en résulte contribue à la diversité biologique. Ceci est particulièrement explicite au cours du cycle de vie du virus d'immunodé cience humaine de type 1 (VIH-1). En utilisant la programmation par contraintes, nous proposons un modèle de régulation de l'épissage alternatif de VIH-1. Ce dernier intègre di érentes échelles (un unique site d'épissage contre plusieurs sites d'épissage) et nous permet ainsi d'exploiter des données expérimentales de natures di érentes à notre disposition. Mots-clés : bioinformatique, biologie computationnelle, programmation par contraintes, modélisation, système hybride, épissage alternatif, VIH-1 Multi-site model of alternative splicing regulation 3

A New Compromise Decision-making Model based on TOPSIS and VIKOR for Solving Multi-objective Large-scale Programming Problems with a Block Angular Structure under Uncertainty

This paper proposes a compromise model, based on a new method, to solve the multi-objective large-scale linear programming (MOLSLP) problems with block angular structure involving fuzzy parameters. The problem involves fuzzy parameters in the objective functions and constraints. In this compromise programming method, two concepts are considered simultaneously. First of them is that the optimal ...

Multiscale Modeling of Alternative Splicing Regulation

Alternative splicing is a key process in post-transcriptional regulation, by which several kinds of mature RNA can be obtained from the same premessenger RNA. Using a constraint programming approach, we model the alternative splicing regulation at different scales (single site vs. multiple sites), thus exploiting different types of available experimental data.
