Imaging Complexity: Visualizing Nature with Bioanalytical Chemistry

The understanding of complex biological processes in their spatial context is crucial to modern molecular medicine and requires innovations in bioanalytical technologies. Mass Spectrometry based spatial biology is revolutionizing fundamental and applied life science research. This implies that future diagnostics will no longer rely on a single molecule but require insight into the intricate biochemical interplay of molecular pathways across the omics.

As such, bioanalytical chemistry technologies in the “omics” arena play an increasingly important role in unraveling life’s complexity. Technological advances have increased methodological sensitivity, allowing researchers to acquire detailed molecular information of smaller and smaller samples imperative to understand cellular or subcellular chemistry. The biggest challenge is to put that concerted information in the context of the biological problem the samples originate from.

As a result, innovative molecular imaging technologies at the single cell level, have impacted both fundamental and translational biomedical research. Sensitive and selective molecular microscopes in modern spatial biology offer new insights in spatial and molecular complexity of cellular metabolism that contextualize cellular function in health and disease.

Imaging mass spectrometry has evolved to demonstrate it’s ability to visualize this almost inconceivable complexity. It’s capabilities of revealing contextual, local molecular information on the microscale aid researchers to provide fundamental insights into biological processes that will impact the future of personalized health and care.

Multi-Omics Integration to Define the Molecular Architecture of the Aging Brain

Brian Hoffmann is the Director of Protein Sciences and Mass Spectrometry Services at The Jackson Laboratory, where his lab utilizes state-of the-art mass spectrometry technologies to advance a variety of research areas, including research on the aging brain and Alzheimer’s Disease (AD). 

His presentation will focus on his collaborative research utilizing a combination of spatial lipidomics, proteomics, and transcriptomics to identify molecular mechanisms in the brain.  Through these high-resolution multi-scale approaches, they are able to investigate protein and lipid homeostasis in the aging and AD brain at the single cell level. 

In addition, the region of interest information collected from the spatial omics approaches is utilized to inform the specific neurons that are targeted for patch-proteomics experiments in which electrophysiology is coupled single neuron proteomes.  This approach was utilized to define single cell proteomic changes in aging and presymptomatic neurons of wild-type and AD mouse models across ages to identify molecular changes before onset of the symptomatic disease state.

Deciphering The Cellular and Molecular Basis of Axolotl Limb Regeneration Using Multimodal Imaging and Omics

The axolotl salamander (Ambystoma mexicanum) is one of the few vertebrates capable of regenerating complex structures, including an entire adult limb, following amputation. Unlike mammals, which respond to injury with scar formation, axolotls mount a highly coordinated regenerative response in which the remaining tissues are remodeled, and a new limb is rebuilt with remarkable fidelity. Understanding how this process is orchestrated across dozens of cell types through dynamic tissue reorganization demands approaches that can resolve molecular and cellular identity within their spatial tissue context.

This presentation highlights our use of single-cell transcriptomics, multiplexed RNA imaging, whole-mount tissue clearing, genetic reporter animals, and functional gene perturbation to map the cellular landscape of the regenerating limb. Through this integrative approach, we have identified candidate signaling pathways that mediate intercellular communication and are functionally required for regeneration to proceed.

These findings illustrate how multimodal imaging and omics strategies can unlock the complexity of regenerating tissues, with broader implications for understanding tissue repair across vertebrates.

Statistics, Machine Learning and AI for Interpreting Mass Spectrometry Imaging Experiments

Mass spectrometry imaging (MSI) characterizes the spatial distribution and molecular composition of tissues at high resolution. This technology is broadly applied in biological and clinical research, including disease diagnosis, prognosis, and drug delivery studies. Our lab aims to enable robust statistical analyses of high-dimensional MSI experiments with complex designs, improve interpretability of MSI datasets, and facilitate reproducible workflows for these applications. The open-source package Cardinal supports advanced functionalities for data preprocessing, for interpretation of MSI experiments with statistical, machine learning and AI algorithms, and for efficient handling of large datasets through out-of-memory data structures.

This presentation overviews the functionalities that we have recently added to Cardinal and its companion software packages. These include TIMSImaging for processing trapped ion mobility mass spectrometry imaging data; functionalities for statistical analysis of differentially abundant analytes in experiments with multiple biological replicates, conditions, and regions of interest; and Teardrop for co-registration of images from multiple complementary biomolecular modalities.

We demonstrate using several case studies that these developments increase the scope of analyses available to the research community through free and open source software, and hope that this will facilitate even broader adoption of MSI.

Professor, College of Engineering, and Faculty Fellow, Barnett Institute for Chemical and Biological Analysis, Northeastern University

From Protein Variation to Biological Functions

Biological functions are reflected in the natural variation of proteome configurations across individual cells. Single-cell proteomics methods may decode this variation and empower inference of biological mechanisms with minimal assumptions. This promise is beginning to be realized by sensitive and scalable mass spectrometry methods. I will discuss approaches that have allowed us to measure and interpret protein covariation in different biological systems, including primary macrophages and melanoma cells expressing markers for drug-resistance priming. The focus of the talk will be on conceptual innovations and data interpretation leading towards molecular mechanisms.

Large Scale AI-Assisted Knowledge Integration for Protein Biology

Discovery in biomedicine requires interpreting experiments in the context of prior knowledge and existing data on the function of proteins and other biomolecules. However, this process is fundamentally limited by the fact that the large body of existing data and published knowledge is fragmented such that it cannot be readily used in an actionable form by scientists.

Through examples from our recent work, we introduce the key components of a technical framework that could overcome these issues. First artificial intelligence-based data annotation and machine reading, coupled to semantic technologies leveraging bio-ontologies enable large-scale data integration across literature and structured databases.

From this unified knowledge base, predictive and explanatory models of protein function and cellular behavior can be assembled that allow interpreting novel experimental observations and proposing hypotheses to be validated experimentally.

These technologies enable a cycle between experimentation and data interpretation in which human scientists can leverage machine-assisted data integration and interpretation to accelerate discovery.

Accelerating Drug Discovery Via Geometric and Generative AI

AI for drug discovery is an emerging field that aims to computationally design new proteins or molecules with desired properties. Traditional experimental approaches to drug discovery are time-consuming and labor-intensive, due to the large combinatorial search space of molecule and protein structures.

In this talk, I will describe how to accelerate drug discovery via novel generative and geometric deep learning methods. First, I will introduce junction tree variational autoencoder (JT-VAE), a generative model for molecular graphs. Inspired by probabilistic graphical models, JT-VAE leverages the low tree-width of molecular graphs and represents a molecule as a junction tree of chemical motifs.

Second, I will present Neural Euler’s Rotation Equation (NERE), an equivariant rotation prediction network inspired by rigid-body dynamics. Based on NERE, they developed an unsupervised binding energy prediction method that estimates the likelihood of a protein complex via SE(3) denoising score matching.

Lastly, I will demonstrate how these algorithmic innovations make real-world impacts on drug discovery. Through collaboration with biologists in wet labs, they successfully designed new antibiotics to fight against antimicrobial resistance and new antibodies with potential for cancer immunotherapy.

Understanding What Therapeutic Drugs Really Do

Almost all drugs act on proteins, are proteins, make or degrade proteins and it has been known since the days of Paracelsus that drugs exert their effects in a dose-dependent fashion. The molecular processes leading to a drug-induced change in cellular phenotype can be roughly divided into: i) target binding, ii) pathway engagement, and iii) cellular reprogramming to arrive at a new viable state or cell death, together forming the mechanism of action (MoA) of a drug. Today, quantitative mass spectrometry is the most comprehensive approach for the proteome-wide characterization of drugs on all three levels because of its unique ability to assay thousands of proteins and their post-translational modifications in complex cellular backgrounds in parallel.

In this presentation, I will introduce the proteome-wide decryptT, decryptM and decryptE technologies that measure target deconvolution, pathway engagement and cellular reprogramming in a fully dose-dependent fashion respectively. Based on the analysis of >3,000 drugs including small molecules and antibodies, examples for drug characterization at all three levels will be discussed, particularly focusing on unexpected or even surprising findings. These include drug repurposing opportunities for kinase inhibitors, the long elusive MoA or Rituximab or the loss of T-cell receptor components in T-cells in response to HDAC inhibitors.

We have developed CurveCurator to put proteome-wide dose-response measurements on a solid statistical foundation and deposited the millions of dose-response curves and derived cellular EC50 values obtained into proteomicsdb.org for FAIR data sharing and mining by the scientific community. Examples for how the data may be used will be highlighted by ascribing new functions to proteins and phosphorylation sites based on their consistent responses to drugs that target known proteins, signaling pathways or cellular machines. We expect that the various implementations of the general “decrypt” approach will become a standard in drug discovery and pharmacology.

Roger Aebersold

Dr. Rudolph Aebersold

Head, Department of Biology
Institute of Molecular System Biology ETH Zurich, Zurich, Switzerland

Lecture: SWATH-MS: Principles, current state and new developments

Bio

Ruedi Aebersold is one of the pioneers in the field of proteomics. He is known for developing a series of methods that have found wide application in analytical protein chemistry and proteomics like a new class of reagents termed Isotope Coded Affinity Tag (ICAT) reagents used in quantitative mass spectrometry. Professor Aebersold and his team of researchers use the protein profiles determined by this method to differentiate cells in different states, such as noncancerous versus cancerous cells, and to systematically study how cells respond to external stimuli. These “snapshot” profiles indicate which cells contain abnormal levels of certain proteins. This is expected to lead to new diagnostic markers for disease and to a more complete understanding of the biochemical processes that control and constitute cell physiology.

Professor Aebersold serves on the Scientific Advisory Committees of numerous academic and private sector research organizations and is a member of several editorial boards in the fields of protein science, genomics, and proteomics.

He is a native of Switzerland and obtained his PhD in Cellular Biology at the Biocenter of the University of Basel in 1983. Since that time, he is a faculty member of the Universities of Washington and British Columbia, until 2000, when he co-founded the Institute for Systems Biology in Seattle. In 2004, he accepted a position as full professor at the Institute of Biotechnology at the Swiss Federal Institute of Technology (ETH) in Zurich, where in January 2005, his research group became the first integral part of the newly founded Institute of Molecular Systems Biology.
