• Title: Comparison of splicing in Weri-Rb cells and PPCs with splicing in the retina

  Research questions:

  • How preserved is the splicing between Weri-Rb cells and PPCs compared to the retina?
  • Optional: validation of splicing events with RT-PCR

  Description

  Inherited retinal diseases (IRDs) are the most common cause of blindness in adults. IRDs are often caused by variants that alter splicing. To identify splice altering variants in IRD patients, splice assays are used. At the moment, splice assays are performed in human embryonic kidney (HEK293T) cells. The problem is that splicing is a tissue specific process. To correctly identify effects of possibly splice altering variants on the retina we need a better model to test the splice assays. Possible options to replace the HEK293T cells with more retina like cells are Weri-Rb cells and photoreceptor precursor cells (PPCs). Weri-Rb cells are human retinoblastoma cells. Photoreceptor precursor cells are post-mitotic precursor cells which can differentiate into cones or rods.

  New long read sequencing techniques have brought new insights into transcriptomics. By comparing pacbio long read RNA sequencing data for retina, Weri-Rb cells and PPCs we want to identify splicing events that are preserved. If the splicing of the cells is similar to the splicing in the retina, the cells can be used to replace HEK293T cells in the study of splice assays. After identifying splicing event in silico, it is possible to validate the findings in the lab with RT-PCR.

• Title: Computational approach for drug repurposing

  Supervisors:

  Peter-Bram ‘t Hoen and colleagues

  Scope:

  The international rare disease research consortium (IRDiRC) set an ambitious goal for 2027: the development of 1000 novel therapies for patients with rare diseases, the majority of which for diseases without any current treatment options. Drug repurposing, the reuse of approved drugs for new indications, is a  key element in this strategy, because the clinical development trajectory is usually much shorter and the expenses for their development are lower. In this project, you will work on novel strategies to prioritize candidate drugs based on molecular -omics (RNA-seq, proteomics, metabolomics) data and knowledge on the similarity of symptoms. You will focus on diseases for which we have collected a lot of data, e.g. myotonic dystrophy and Koolen-de Vries syndrome. You will develop innovative approaches, for example using network inference methods and deep learning.

  Tasks:

  -You will create multimodal knowledge networks that combine information on disease symptoms, and molecular signatures of diseases and drugs and existing indications for these drugs.

  -You will utilize these knowledge networks for semisupervised learning and predicting drug repurposing candidates. You will explore the use deep learning frameworks like graph convolutional networks.

  Requirements:

  -Studying for a Master degree in Bioinformatics, Computer Sciences, Artificial Intelligence, Molecular Life Sciences or similar

  -Student should be available for at least 5 months

  -Basic R or python programming experience

  Offered:

  -An internship in a environment with a strong focus on computational method development and many collaborations with biomedical and clinical scientists

  -Experience of being embedded in a research group with related activities such as journal clubs and social events

  -Weekly and ad-hoc meetings with supervisors

  -Ample opportunities to present your work in internal and external meetings

• Title: Understanding and predicting the molecular basis of exon-skipping as a therapeutic approach for USH2A-associated disease

  Description

  The human protein usherin, encoded by the USH2A gene, is involved in hearing and vision as a member of the USH2 complex. This complex forms the stereociliary ankle link complex at the apical surface of the sensory cells of the inner ear, the cochlear hair cells, and is required for the proper formation of the developing hair bundles. In retina photoreceptors, the USH2 complex is present at the periciliary membrane and is thought to play a role in regulating intracellular protein transport.
   
  Mutations in USH2A either lead to Usher syndrome, a both genetically and clinically heterogeneous condition characterized by progressive vision loss as a consequence of retinitis pigmentosa combined with sensorineural congenital hearing impairment, or to non-syndromic retinitis pigmentosa. The hearing impairment can be partially compensated by fitting of hearing aids or cochlear implants. Although, for the loss of vision currently no treatment options exist.
   
  dr. Erwin van Wijk's group at the department of Otorhinolaryngology focuses on unraveling the pathogenic mechanisms underlying Usher syndrome and developing genetic therapies for this condition. One of their successful approaches consists of an RNA-based antisense oligonucleotide (AON) therapy which induces the in frame skipping of a mutated exon during the process of pre-mRNA splicing. The 3D-structure of the resulting protein indicates that a well-chosen exon-skip can result in a functional, albeit slightly shortened protein. The first AON for USH2A-associated disease is currently being evaluated in a phase 1/2 clinical trial.
   
  In this internship, you will be studying and identifying the requirements for a successful exon-skipping approach. You will take into account the available information on, amongst others,  protein type, domain content, 3D-structure, exon-boundaries, splice modulating factors, evolutionary conservation, and protein-protein interactions. The goal is to generate a bio-informatic pipeline which enables the prediction of successful targets for the development of exon-skipping therapies.

• Title: Combining complexome profiling data and protein homology to discover apicomplexan protein function

  Project Description

  Apicomplexans are a phylum of unicellular eukaryotic parasites. Members of this phylum include Plasmodium and Toxoplasma, which are responsible for the deadly diseases malaria and toxoplasmosis. These species have a complex life cycle, consisting of multiple life stages. Our current understanding of the molecular functioning of these organisms is lacking. The aim of this project is to discover the function of genes and proteins in Plasmodium and Toxoplasma species.

  During this project, the student will attempt to assign functions to unannotated proteins, by employing a systematic and multi-faceted bioinformatics approach, combining orthogonal data sources. The
  student will employ a combination of bioinformatics approaches to predict protein function.
  Firstly, existing homology detection software will be used to systematically determine homology between proteins from the Plasmodium, Toxoplasma and human proteomes. Secondly, a collection of
  publicly available complexome profiles fromToxoplasma and Plasmodium will be analyzed. Complexome profiling is a new ‘omics approach that comprehensively interrogates the entire protein complex composition and protein interactions within a sample. This new type of data will be analyzed using specialized software developed at the CMBI, to identify possible protein interactors and associated protein complexes. The results from these approaches will then be integrated to robustly assign putative functions to as of yet
  unannotated proteins, in both Plasmodium and Toxoplasma.

  By assigning functions to uncharacterized proteins, this project will increase our knowledge on the molecular functioning of these parasites, their complex life cycle and their pathogenicity. An increased understanding of the molecular functioning of these organisms will inform and aid research efforts to combat malaria as well as toxoplasmosis. Additionally, proteins whose functions are uncovered in this project will be novel candidates in the effort to identify potential drug targets. 

  During this project the student will get the chance to gain general experience in the analysis and processing of data, in a preferred programming language. Additionally, the student will get to know and apply multiple methods central to bioinformatics. These tools will be applied to gain insight in the functioning and pathogenicity of complex and interesting species that are a threat to global health. 

  Programming skills: An ambition to work with large datasets is required and basic programming skills are preferred.

• Title: Detecting intron retention and exon skipping events in NA12878

  Description:

  Alternative splicing plays a major role in proteomic diversity (Liu et al., 2017). Long-read transcriptomics technology has allowed for the detection of many novel transcript structures, among which intron retention and exon skipping. These events have been found extensively in various forms of cancer, for example (Dvinge & Bradley, 2015). However, intron retention events are widespread and occur in normal biological settings to regulate gene expression (Braunschweig et al., n.d.; Wong, Au, Ritchie, & Rasko, 2016). We would like to know whether we can detect these events on the protein level and what possible (effect of) IR/ES occurs in healthy cells, using the well-studied cell line NA12878.

  Outline steps:

  1. Literature review.
  2. Use data available for NA12878 and/or other long read datasets with paired proteomics data.
  3. Identify intron retention and exon skipping events on the transcriptome level.
  4. Create customized search dictionary to be able to identify these events.
  5. Quantify events/identify patterns or associations with other genes, and interpret biological/medical significance.
  6. Write up.

  Requirements:

  • Master in computational biology, bioinformatics or similar.
  • Basic programming skills (python preferred), knowledge of Linux command line.
  • Solid statistical knowledge.
  • Prior experience handling large datasets preferred.
  • 6 months or longer available for internship.

• Title: Exploiting Plasmodium genome variation to understand immune evasion, antigenic diversity and to develop better vaccines.

  Plasmodium genomes are being sequenced at a high rate (e.g.https://www.malariagen.net/projects/pf3k), and data can be exploited to better understand the sequence variation. Specific question that we want to answer are: Which proteins do show the highest level of variation and is this variation linked to whether they are e.g. immunogenic, expressed in specific stages in the Plasmodium developmental stage, are exposed to the outside of the cell or are encoded on specific regions of the chromosome. The project combines the gathering of relevant data (e.g. about immunogenicity, or about developmental stage dependent expression of the protein), the analysis of the relationships between those data and the critical thinking about causal relationships versus correlations.

• Title: Analysis of microbiomes obtained with molecular inversion probe (smMIP) next gen seq and design of novel smMIPS to identify human microbiome compositions.

  The metagenomes of bacterial species living in and on humans have uncovered a new angle to predicting and understanding human health and disease.
  Single molecule Molecular Inversion Probes (smMIPS) allow us to derive the composition of a metagenome at unprecendented phylogenetic depth at affordable costs, facilitating large scale analyses. Design of smMIPS for large numbers of genomes, using conserved sequences for the probes, and analysis of the results requires understanding of the experimental techniques that are being used, programming skills and biological knowledge to interpret the results: typical skills of a bioinformatician. In the project the student would first analyze the data that we have already obtained about human metagenomes, using in-house developed software, and would then go on to design new smMIPS to increase the number of species and strains that we can obtain.
   
  Programming skills: An ambition to work with large sequence datasets is required and basic programming skills (e.g. python) are strongly preferred.

• Title: Deconvolution of gene expression data from synovial biopsies of rheumatoid arthritis patients

  Description

  Analysis of gene expression in bulk tissues using RNA sequencing provides important information to understand the processes involved in disease development and progression. However, many tissues are heterogeneous and contain a mix of different cell types. This makes it difficult to identify gene expression levels specific for various cell type, since the expression level of each individual gene can differ between cell types. Disease development and progression or the response to drug therapy is often accompanied by changes in cell composition. For example, an increase of malignant cells and tumor infiltrating cells compared with surrounding cells is an indicator of tumor growth and of the clinical outcome for patients. Thus, the cellular composition of a tissue is important for the understanding of many biological processes.
  Rheumatoid arthritis (RA) is a disease characterized by inflammation of multiple joints, which, if not treated, leads to irreversible joint damage. During joint inflammation cells from the immune system infiltrate in the synovial membrane, leading to the formation of so-called pannus tissue. Synovial biopsies taken from the inflamed joints of RA patients are mainly composed of synovial fibroblasts, macrophages, neutrophils, and lymphocytes. Using publicly available RNAseq datasets, as well as single-cell sequencing data, you will elucidate the constituent cell types and their proportions in synovial biopsies from RA patients by computational deconvolution of gene expression data. Deconvolution is the identification of properties and the relative abundance of components from a mixture. This project will be carried out at the Department of Biomolecular Chemistry in close collaboration with the Centre for Molecular and Biomolecular Informatics with supervision from both departments.

• Title: Building a metagenomics pipeline for analysis of human microbiome sequencing data.

  Background

  The world around us is teeming with microscopic life. The natural habitat of these so-called microbiota, for example in the human intestines or on the skin, is called the microbiome. These bacterial consortia are currently analyzed mostly by sequencing-based approaches, either by marker gene sequencing (MGS) metataxonomics, or by whole-genome sequencing (WGS) shotgun metagenomics. The advantage of WGS over MGS is that it provides insight into gene and metabolic function potential of a microbiome because all free DNA in a sample is sequenced, whereas MGS focuses on one gene only (usually the 16S rRNA gene).

  Challenge

  MGS is relatively cheap and data analysis is straight-forward, and it is still the standard in the field. In contrast, WGS is relatively expensive and very computational intensive. Nevertheless, more and more WGS datasets are being generated, as WGS is slowly becoming more affordable. At the CMBI, we currently lack a dedicated pipeline for analysis of metagenomics data. In order for us to be prepared for future projects we want to invest now in setting-up a WGS analysis pipeline.

  Project description

  A plethora of tools is currently available for analysis of WGS data. With these existing tools the student will have to build an analysis pipeline for metagenomics data. This means that the student will first have to study in-depth the different options available. Thereafter, a combination of tools will be used to build a comprehensive pipeline. Note that there is no need for the students to write bioinformatics tools or algorithms themselves. Depending on preferences and needs, this pipeline can in time be expanded with other tools and functionalities. Therefore, documentation (e.g. GitHub), portability (e.g. Docker or Jupyter) and structured programming is important in this project. Also, from a QC point-of-view the monitoring and detailed reporting of all pipeline steps is crucial. In final phase of the project, the student will validate his/her pipeline with available metagenomics datasets of different human microbiome niches, as reported in high-quality literature studies. In conclusion, we offer a lot of diversity and challenges for a highly motivated and enthusiastic student, in a flexible, supportive and professional academic environment.

• Title: In silico validation of a novel smMIP-based sequencing method for microbiome profiling.

  Background

  The world around us is teeming with microscopic life. The natural habitat of these so-called microbiota, for example in the human intestines or on the skin, is called the microbiome. These bacterial consortia are currently analyzed mostly by sequencing-based approaches, either by marker gene sequencing (MGS) metataxonomics, or by whole-genome sequencing (WGS) shotgun metagenomics. Recently, a novel molecular / sequencing method called smMIP was developed for profiling of genes with a very high sensitivity. Within the Radboudumc, this smMIP method, for single-molecule molecular inversion probe, is currently being adapted for in-depth and high resolution profiling of microbiota.

  Challenge

  Recent studies show that smMIP is highly sensitive method for profiling of genes or RNA transcripts. However, its application for studying microbiomes has not been explored yet. Multiple departments within the Radboudumc are currently working together on application and validation of smMIP for microbiota profiling (i.e. dept. of Biochemistry, CMBI Bioinformatics and Dermatology). Pilot sequencing data has been generated, but several other important validations are yet to be performed, one of these is an extensive in silico validation.

  Project description

  The student will be working with a panel of smMIPs that is designed to target the vaginal microbiome, which is developed in our institute. Using existing smMIP analysis software we want to perform an in silico validation on a published metagenome data set of vaginome samples, to see if theoretical smMIP profiles match those microbiota profiles as found by metagenome analysis of the same data. As metagenomics is not trivial, the student will be working closely together with another student who will be fully dedicated on building an analysis pipeline for metagenomics data. Furthermore, the smMIP software is not build for the here intended purpose of in silico profiling of metagenome sequencing reads, therefore asking creativity from the student in adapting the smMIP bioinformatics tool to our specific needs. In parallel, another pilot study will be performed in which 16S vaginome profiles are compared to those retrieved by the smMIP approach. In conclusion, we offer a lot of diversity and challenges for a highly motivated and enthusiastic student, in a flexible, supportive and professional academic environment.

• Title: Improving HOPE by comparing Variant Effect Predictions

  Description

  HOPE is our own in-house server for the prediction of mutational effects. This server is specifically aimed at the medical scientist and produces a report that is clear and understandable for everyone without a background in structural bioinformatics. HOPE has been running for several years and is being used by researchers all over the world. In order to keep this server up to date we perform small tests in which we select mutations that were described in high-end journals such as The American Journal of Human Genetics and Nature Genetics. We compare the effect predictions made in these article with those made by our HOPE server (and eventually also with predictions made by other widely-used automatic online servers). The results should be used to improve the predictions made by HOPE.

• Title: Integrative Modelling of peptide:MHC class II complexes

  Upon the cleavage of proteins into short peptides, some interact with MHC molecules and are delivered to the cell surface via the MHC molecule to be presented to the immune cells. If a foreign peptide is presented by the MHC molecule the adaptive immune response will be triggered. The main determinant step of this antigen presentation is the binding of the peptide and the MHC molecule. Deciphering the mechanism underlying peptide:MHC interactions is valuable in designing vaccines for infectious diseases, cancer immunotherapy and understanding the cause to autoimmune diseases. Three-dimensional (3D) structures of peptide:MHC complexes provide fundamental insights of interaction specificities, binding affinities and sensitivity to mutations.
  Complementary to experimental methods, modelling provides a valuable tool for generating 3D models of peptide:MHC complexes.

  Existing computational research methods are mostly effective for MHC class I but not for MHC class II. The modelling of peptide:MHCII is crucial and there are few experiments on this type of interaction compared to peptide:MHCI interactions. MHC class II molecules interact with exogenous peptides and show different type of interaction, mainly due to MHC II molecule’s intrinsic different binding groove. With its open peptide-binding cleft it tends to interact with longer peptides and also it has more and different anchor pockets.

  We have developed a framework for the modelling of peptide:MHC class I complexes in our lab so far. The internship project will consist of setting up the computational framework to do 3D modelling of peptide:MHCII complexes which would allow us to produce large quantities of structures, that can be used for further analysis, crucial for vaccines development. Following to the modelling of peptide:MHCII complexes, there is room to extend the project  in scoring the models to select high-quality models to spot the specifity of immune responses

  The student will have the opportunities to:

  • Learn to perform homology modelling
  • Learn the basics of biophysics used for loop modelling
  • Learn Git and GitHub
  • Contribute to extend our modelling framework to peptide:MHC class II complexes

• Title: Protein Protein Contact Predictions

  Description

  Proteins can hardly ever function on their own. Many proteins are found in homo- and heteromeric complexes, and many others are found in a transient complex at least once during their lifecycle. Interactions made by these proteins can be disturbed by mutations, which often lead a non-functional protein complex and eventually a disease. Therefore, it would be interesting to predict the effects of mutations that occur on protein surfaces. However, information about interacting residues on surfaces is still scarce and only a few protein protein interaction servers exist.

  
  In collaboration with a research group in Amsterdam, we have linked their PPI-prediction server SERENDIP to a script that visualizes the predictions in a YASARA scene. A possible student project would be to test and analyse these predictions.

• Title: Consensus Variant Effect Prediction

  In order to correctly treat patients, it is beneficial to understand the molecular base of their disease or syndrome. Mutations that occur in the coding sequence of proteins might have effect on ligand binding, membrane anchoring, general stability/folding, interactions with other proteins, etc. Nowadays, several online servers that can analyse these effects exist. One of them is our own HOPE server, a server that can analyse the protein structure in detail and will provide an extensive report readable for the medical scientist. Other predictions servers often provide a result that contains only a binair answer (damaging or not), or a value (0 to 10). HOPE's results could be strengthened by combining its textual report with a consensus prediction that would be a combination of these other servers.

• Title: Timing and localization of gene expression in the DM1 locus to advance our understanding of the brain phenotype of myotonic dystrophy

  Our aim is to obtain a deeper understanding of the expression of the genes in the DM1 locus (Fig. 1), the DMPK and DM1-AS transcripts in particular, during brain development, their regional expression patterns in the brain and their expression levels in different cell types present in the brain. These expression patterns can then subsequently be related to the brain abnormalities observed in DM1. In analogy to published work on DMD3, you will be using public large-scale gene expression resources from human and mice, including the Allen Brain Atlas, the FANTOM5 study and the 10x genomics mouse brain single cell dataset. You will be analyzing, comparing and interpreting the expression signatures present in these different resources.
  
  Programming skills: An ambition to work with large datasets is required and basic programming skills (R, python) are strongly preferred.
