Quantitative Biology - Quantitative Methods - Abstract
The problem of RNA secondary structure design (also called inverse folding) is the following: given a target secondary structure, one aims to create a sequence that folds into, or is compatible with, a given structure. In several practical applications in biology, additional constraints must be taken into account, such as the presence/absence of regulatory motifs, either at a specific location or anywhere in the sequence. In this study, we investigate the design of RNA sequences from their targeted secondary structure, given these additional sequence constraints. To this purpose, we develop a general framework based on concepts of language theory, namely context-free grammars and finite automata. We efficiently combine a comprehensive set of constraints into a unifying context-free grammar of moderate size. From there, we use generic generic algorithms to perform a (weighted) random generation, or an exhaustive enumeration, of candidate sequences. The resulting method, whose complexity scales linearly with the length of the RNA, was implemented as a standalone program. The resulting software was embedded into a publicly available dedicated web server. The applicability demonstrated of the method on a concrete case study dedicated to Exon Splicing Enhancers, in which our approach was successfully used in the design of \emph{in vitro} experiments., Comment: ACM BCB 2013 - ACM Conference on Bioinformatics, Computational Biology and Biomedical Informatics (2013)

Quantitative Biology - Quantitative Methods ,Computer Science - Data Structures and Algorithms - Abstract
We present a general setting for structure-sequence comparison in a large class of RNA structures that unifies and generalizes a number of recent works on specific families on structures. Our approach is based on tree decomposition of structures and gives rises to a general parameterized algorithm, where the exponential part of the complexity depends on the family of structures. For each of the previously studied families, our algorithm has the same complexity as the specific algorithm that had been given before., Comment: (2012)

Computer Science - Discrete Mathematics - Abstract
Consider a class of decomposable combinatorial structures, using different types of atoms $\Atoms = \{\At_1,\ldots ,\At_{|{\Atoms}|}\}$. We address the random generation of such structures with respect to a size $n$ and a targeted distribution in $k$ of its \emph{distinguished} atoms. We consider two variations on this problem. In the first alternative, the targeted distribution is given by $k$ real numbers $\TargFreq_1, \ldots, \TargFreq_k$ such that $0 < \TargFreq_i < 1$ for all $i$ and $\TargFreq_1+\cdots+\TargFreq_k \leq 1$. We aim to generate random structures among the whole set of structures of a given size $n$, in such a way that the {\em expected} frequency of any distinguished atom $\At_i$ equals $\TargFreq_i$. We address this problem by weighting the atoms with a $k$-tuple $\Weights$ of real-valued weights, inducing a weighted distribution over the set of structures of size $n$. We first adapt the classical recursive random generation scheme into an algorithm taking $\bigO{n^{1+o(1)}+mn\log{n}}$ arithmetic operations to draw $m$ structures from the $\Weights$-weighted distribution. Secondly, we address the analytical computation of weights such that the targeted frequencies are achieved asymptotically, i. e. for large values of $n$. We derive systems of functional equations whose resolution gives an explicit relationship between $\Weights$ and $\TargFreq_1, \ldots, \TargFreq_k$. Lastly, we give an algorithm in $\bigO{k n^4}$ for the inverse problem, {\it i.e.} computing the frequencies associated with a given $k$-tuple $\Weights$ of weights, and an optimized version in $\bigO{k n^2}$ in the case of context-free languages. This allows for a heuristic resolution of the weights/frequencies relationship suitable for complex specifications. In the second alternative, the targeted distribution is given by a $k$ natural numbers $n_1, \ldots, n_k$ such that $n_1+\cdots+n_k+r=n$ where $r \geq 0$ is the number of undistinguished atoms. The structures must be generated uniformly among the set of structures of size $n$ that contain {\em exactly} $n_i$ atoms $\At_i$ ($1 \leq i \leq k$). We give a $\bigO{r^2\prod_{i=1}^k n_i^2 +m n k \log n}$ algorithm for generating $m$ structures, which simplifies into a $\bigO{r\prod_{i=1}^k n_i +m n}$ for regular specifications.

The U2AF heterodimer has been well studied for its role in defining functional 3' splice sites in pre-mRNA splicing, but many fundamental questions still remain unaddressed regarding the function of U2AF in mammalian genomes. Through genome-wide analysis of U2AF-RNA interactions, we report that U2AF has the capacity to directly define ~88% of functional 3' splice sites in the human genome, but numerous U2AF binding events also occur in intronic locations. Mechanistic dissection reveals that upstream intronic binding events interfere with the immediate downstream 3' splice site associated either with the alternative exon, to cause exon skipping, or with the competing constitutive exon, to induce exon inclusion. We further demonstrate partial functional impairment with leukemia-associated mutations in U2AF35, but not U2AF65, in regulated splicing. These findings reveal the genomic function and regulatory mechanism of U2AF in both normal and disease states.

This paper presents some first results on how to perform uniform random walks (where every trace has the same probability to occur) in very large models. The models considered here are described in a succinct way as a set of communicating reactive modules. The method relies upon techniques for counting and drawing uniformly at random words in regular languages. Each module is considered as an automaton defining such a language. It is shown how it is possible to combine local uniform drawings of traces, and to obtain some global uniform random sampling, without construction of the global model.

Certain families of combinatorial objects admit recursive descriptions in terms of generating trees: each node of the tree corresponds to an object, and the branch leading to the node encodes the choices made in the construction of the object. Generating trees lead to a fast computation of enumeration sequences (sometimes, to explicit formulae as well) and provide efficient random generation algorithms. We investigate the links between the structural properties of the rewriting rules defining such trees and the rationality, algebraicity, or transcendence of the corresponding generating function., Comment: This article corresponds, up to minor typo corrections, to the article submitted to Discrete Mathematics (Elsevier) in Nov. 1999, and published in its vol. 246(1-3), March 2002, pp. 29-55

This article proposes to use an RNA graph similarity metric, based on the MCES resolution problem, to compare the occurrences of specific complex motifs in RNA graphs, according to their context represented as subgraph. We rely on a new modeling by graphs of these contexts, at two different levels of granularity, and obtain a classification of these graphs, which is consistent with the RNA 3D structure. RNA many non-translational functions, as a ribozyme, riboswitch, or ribosome, require complex structures. Those are composed of a rigid skeleton, a set of canonical interactions called the secondary structure. Decades of experimental and theoretical work have produced precise thermodynamic parameters and efficient algorithms to predict, from sequence, the secondary structure of RNA molecules. On top of the skeleton, the nucleotides form an intricate network of interactions that are not captured by present thermodynamic models. This network has been shown to be composed of modular motifs, that are linked to function, and have been leveraged for better prediction and design. A peculiar subclass of complex structural motifs are those connecting RNA regions far away in the secondary structure. They are crucial to predict since they determine the global shape of the molecule, therefore important for the function. In this paper, we show by using our graph approach that the context is important for the formation of conserved complex structural motifs. We furthermore show that a natural classification of structural variants of the motifs emerges from their context. We explore the cases of three known motif families and we exhibit their experimentally emerging classification., LIPIcs, Vol. 190, 19th International Symposium on Experimental Algorithms (SEA 2021), pages 19:1-19:18

National audience; RNA structure design methods have grown in complexity to cover an increasing scope of application. Recent approaches combine an initial random generation with a local optimization step, and consider both a user-specified secondary structure and sets of mandatory and forbidden substrings. Although these additional constraints lead to better design results, they may interfere with the local optimization phase. Indeed, forbidden substrings may disrupt the connectivity of their underlying search space, a key property for the success of the local search. A naive connectivity test would explore the whole graph of candidate sequences, leading to an exponential time connectivity test. In this work, we propose two partial algorithms based on compact graph structures-the De Bruijn graphs and the Aho-Corasick automaton-allowing the detection of disconnectivity in time independent from the length of RNA sequence. Tested on random instances, our tests were able to detect the disconnectivity with sensitivity ranging between 35% and 55%, motivating further research.

International audience; Systems biology studies biological networks and the relations between them. Among the various types of biological networks, we focus on metabolic pathways and gene neighboring networks, respectively modeled by directed and undirected graphs. We attempt to identify maximal sets of consecutive metabolic reactions catalyzed by products of neighboring genes. The approach proposed here is HNet, a non-exhaustive exact method that is capable to take into account (i) skipped genes and/or reactions and (ii) metabolic pathways containing cycles. HNet relies on a previously described graph reduction method and on trail finding in a directed graph by performing path finding in its line graph. A trail is a path that can contain repeated vertices, but not repeated arcs. HNet is used to analyze the genomes and metabolic networks of 50 prokaryotic species in order to gain insight into metabolic pathway evolution.

International audience; The wealth of the combinatorics of nucleotide base pairs enables RNA molecules to assemble into sophisticated interaction networks, which are used to create complex 3D substructures. These interaction networks are essential to shape the 3D architecture of the molecule, and also to provide the key elements to carry molecular functions such as protein or lig-and binding. They are made of organised sets of long-range tertiary interactions which connect distinct secondary structure elements in 3D structures. Here, we present a de novo data-driven approach to extract automatically from large data sets of full RNA 3D structures the recurrent interaction networks (RINs). Our methodology enables us for the first time to detect the interaction networks connecting distinct components of the RNA structure, highlighting their diversity and conservation through non-related functional RNAs. We use a graphical model to perform pairwise comparisons of all RNA structures available and to extract RINs and modules. Our analysis yields a complete catalog of RNA 3D structures available in the Protein Data Bank and reveals the intricate hierarchical organization of the RNA interaction networks and modules. We assembled our results in an online database (http://carnaval.lri.fr) which will be regularly updated. Within the site, a tool allows users with a novel RNA structure to detect automatically whether the novel structure contains previously observed RINs.

National audience; Le problème du design consiste à concevoir une ou des séquences d’ARN qui vont, dans un modèleénergétique, se replier en une structure cible. Les algorithmes déjà existants dans le domaine negèrent pour la plupart pas l’ajout au problème des contraintes de séquence, c’est-à-dire l’interdictionou l’obligation d’utiliser certains motifs.Zhou et al. (2013) ont proposé un algorithme qui utilise de la génération aléatoire dans un langageformel conditionné par un automate fini qui gère les contraintes de motifs interdits/imposés et unegrammaire non contextuelle qui gère les contraintes imposées par la structure recherchée.On propose ici de se baser sur cet algorithme en y ajoutant des optimisations permettant de réduiresa complexité. Ce travail soulève également des questions ouvertes sur la construction efficace d’unautomate (quasi) minimal, ainsi que l’incorporation de contraintes supplémentaires garantissant lerepliement des séquences engendrées vers une structure cible à l’exclusion de tout autre repliement.

National audience; Aligning macromolecules such as proteins, DNAs and RNAs in order to reveal, or conversely exploit, their functional homology is a classic challenge in bioinformatics, with farreaching applications in structure modelling and genome annotations. In the specific context of complex RNAs, featuring pseudoknots, multiple interactions and noncanonical base pairs, multiple algorithmic solutions and tools have been proposed for the structure/sequence alignment problem. However, such tools are seldom used in practice, due in part to their extreme computational demands, and because of their inability to support general types of structures. Recently, a general parameterized algorithm based on tree decomposition of the query structure has been designed by Rinaudo et al. We present an implementation of the algorithm within a tool named LiCoRNA. We compare it against stateoftheart algorithms. We show that it both gracefully specializes into a practical algorithm for simple classes pseudoknot, and offers a general solution for complex pseudoknots, which are explicitly outofreach of competing softwares.

National audience; L’analyse d'expériences bioinformatiques comprend la comparaison des nouveaux résultats obtenus auxdonnées existantes. Durant ces trente dernières années, les scientifiques ont du faire face à une avalanche dedonnées, de différents types, et présentes dans une multitude de bases de données publiques. L’accès auxdonnées publiques se fait par l’interrogation de portails (tels que le portail Entrez du NCBI) au moyen demots clés. Cependant, deux requêtes très similaires peuvent fournir des ensembles de réponses différentsconduisant l’utilisateur à devoir tester différentes reformulations de ses requêtes (termes synonymes,variantes orthographiques, abréviations).... Les résultats obtenus doivent ensuite être filtrés, comparés... Enoutre, chaque ensemble de résultats est classé par le portail (en utilisant le nombre d'occurrences du mot-clédans chaque résultat). Cependant, lorsque plusieurs reformulations sont considérées, il n'est pas simple deproduire un classement triant par ordre de pertinence l'ensemble des résultats recueillis séparément, d'autantque ces résultats peuvent être fournis par centaines.Dans cette démonstration, nous présentons ConQuR-Bio (http://conqur-bio.lri.fr) qui permet auxutilisateurs d'interroger les bases de données publiques du NCBI tout en générant automatiquement toutes lesreformulations possibles et fournit des réponses triées en utilisant des techniques de consensus de classement(ou agrégation de classements). Notre démonstration montrera l’intérêt de notre approche pour des requêtesbiomédicales, lors de la recherche de gènes issus d’EntrezGene et impliqués dans des maladies.

National audience; We try to characterize the evolutionary origin of the enzymatic repertoire of different fungal groups. The characteristics for each of the groups studied are determined through the application of data mining method on enzyme profiles previously determined by comparative genomics. Through the presentation of results for taxonomic groups Agaricomycetes and Pezizomycota, we show that the application of supervised learning methods is effective in extracting information from phylogenetic profiles. We extract specific enzyme activities combinations for each taxonomic groups covered by our analysis. Our approach also enables us to highlight the existence of probable horizontal gene transfers.
