A workflow for annotating the knowledge gaps in metabolic reconstructions using known and hypothetical reactions

Vassily Hatzimanikatis, Meriç Ataman, Jasmin Maria Hafner, Homa Mohammadi Peyhani, Evangelia Vagena, Noushin Hadadi, Anush Chiappino-Pepe

Advances in medicine and biotechnology rely on a deep understanding of biological processes. Despite the increasingly available types and amounts of omics data, significant knowledge gaps remain, with current approaches to identify and curate missing annot ...

NICEdrug.ch, a workflow for rational drug design and systems-level analysis of drug metabolism

Vassily Hatzimanikatis, Jasmin Maria Hafner, Homa Mohammadi Peyhani, Noushin Hadadi, Anush Chiappino-Pepe

The discovery of a drug requires over a decade of intensive research and financial investments – and still has a high risk of failure. To reduce this burden, we developed the NICEdrug.ch resource, which incorporates 250,000 bioactive molecules, and studied ...

Mechanistic insights into bacterial metabolic reprogramming from omics-integrated genome-scale models

Noushin Hadadi, Vikash Kumar Pandey, Anush Chiappino-Pepe, Merten Morales, Florence Mehl

Understanding the adaptive responses of individual bacterial strains is crucial for microbiome engineering approaches that introduce new functionalities into complex microbiomes, such as xenobiotic compound metabolism for soil bioremediation. Adaptation re ...

Functional and Computational Genomics Reveal Unprecedented Flexibility in Stage-Specific Toxoplasma Metabolism

Vassily Hatzimanikatis, Anush Chiappino-Pepe, Matteo Lunghi, Damien Lionel Nicolas, Aarti Krishnan, Dominique Soldati-Favre

To survive and proliferate in diverse host environments with varying nutrient availability, the obligate intracellular parasite Toxoplasma gondii reprograms its metabolism. We have generated and curated a genome-scale metabolic model (iTgo) for the fast-re ...

Genome-Scale Identification of Essential Metabolic Processes for Targeting the Plasmodium Liver Stage

Vassily Hatzimanikatis, Vikash Kumar Pandey, Anush Chiappino-Pepe, Dominique Soldati-Favre

Plasmodium gene functions in mosquito and liver stages remain poorly characterized due to limitations in the throughput of phenotyping at these stages. To fill this gap, we followed more than 1,300 barcoded P. berghei mutants through the life cycle. We dis ...

Analysis of cellular and drug action mechanisms in the malaria parasites using systems biology approaches

Anush Chiappino-Pepe

Malaria puts at risk of infection half of the world population and still kills around half a million people every year. The rapid and worrisome rise of drug-resistant malaria parasites hinders the treatment of malaria and calls for a global collaboration t ...

Bioenergetics-based modeling of Plasmodium falciparum metabolism reveals its essential genes, nutritional requirements, and thermodynamic bottlenecks

Vassily Hatzimanikatis, Meriç Ataman, Stepan Tymoshenko, Dominique Soldati-Favre, Anush Chiappino-Pepe

Novel antimalarial therapies are urgently needed for the fight against drug-resistant para- sites. The metabolism of malaria parasites in infected cells is an attractive source of drug targets but is rather complex. Computational methods can handle this co ...

Integration of Metabolic, Regulatory and Signaling Networks Towards Analysis of Perturbation and Dynamic Responses

Vassily Hatzimanikatis, Meriç Ataman, Vikash Kumar Pandey, Anush Chiappino-Pepe

The expanding generation of dynamic biological data requires approaches that integrate and analyze information from different types of cellular processes –metabolism, regulation, and signaling–, and ultimately increase our insights into the cell behavior u ...
