What is Proteomics?

Proteomics is the extensive study of proteomes, with a focus on protein composition, structure, functions, interactions, expression patterns, and modifications. Proteomics analysis can facilitate biomarker identification and monitoring, and aid in drug development by providing a comprehensive map of protein interactions associated with disease pathways. It is also increasingly used for early disease diagnosis, prognosis, and monitoring disease progression.

Importance of Proteomics Data in Life Science Research

Proteomics studies can provide a comprehensive understanding of the functional aspects of a biological system as protein expression varies over time in response to external as well as internal signals. Key points highlighting its importance include:

• Early Disease Detection and Diagnosis: Proteomics enables the non-invasive detection of diseases through blood and other bodily fluids. It identifies specific protein biomarkers for accurate diagnosis and monitoring.
• Precision Medicine: Proteomics facilitates personalized treatment plans by identifying unique protein signatures. This enhances tumor classification and therapy customization, particularly in cancer research.
• Drug Discovery and Development: Proteomics identifies novel drug targets and maps drug-protein interactions, streamlining drug development. It also provides insights into drug efficacy and safety.
• Understanding Drug Actions and Resistance: Proteomics analyzes how drugs interact with proteins and affect cellular pathways. This knowledge aids in overcoming drug resistance and improving therapy effectiveness.
• Novel Drug Target Identification: Proteomics explores less-mapped areas of the proteome to identify new drug targets. This supports the development of innovative therapeutic interventions.

Proteomics data can also be integrated with other omics data in order to comprehend biological systems more holistically.

Harmonized Proteomics Data

Researchers often struggle with integrating public data and in-house proteomics data due to differences in data formats, acquisition methods, and experimental designs across different sources. Harmonization guarantees that data from various sources is aligned to maintain a consistent format, making it easier to integrate and analyze. Harmonized proteomics datasets include standardized metadata, ensuring that all datasets have consistent and comprehensive descriptions, aiding in better understanding and comparison.  The data is structured to be readily accessible and usable for researchers, facilitating efficient workflows. Polly is an example of a platform that provides such harmonized proteomics data, making it easier for researchers to integrate and utilize diverse datasets.

Solutions and Services for Proteomics Data at Elucidata

Elucidata offers a suite of solutions and services designed to streamline and enhance the harmonization of proteomics data. Our offerings include:

• Data Harmonization: Elucidata’s data harmonization platform, Polly, is designed to standardize and streamline diverse datasets, ensuring consistency and quality. It can ingest proteomics datasets from public sources like PRIDE or CPTAC as well as your in-hose sources. Polly processes these datasets using an author-defined pipeline, and annotates them with metadata fields at the dataset, sample, and feature levels. The platform manages various data formats, including mzTab, mzIdentML, mzML, and SDRF, and converts them into a consistent Gene Cluster Format (GCT) for uniformity. This processed data is then stored in a queryable format, facilitating subsequent exploration and analysis. The harmonization process significantly reduces the effort required for data cleaning and preparation, allowing researchers to focus on deriving meaningful insights from the data​.
• Data Concierge: In-house proteomics datasets can be enhanced with AI-ready data from public sources like PRIDE and CPTAC using Elucidata’s data concierge services. Our experts can locate the required datasets in minutes by querying Polly’s metadata-annotated proteomics collection. We handle the heavy lifting, ensuring every relevant study includes essential information for your analysis, from data matrices to associated metadata and protein intensity tables.
• Data Management (In-house and Public Proteomics Data): Elucidata’s data importers automate data ingestion workflows from sources such as Electronic Lab Notebooks, Amazon S3 buckets, and Contract Research Organizations into Polly. Polly harmonizes these datasets to match your custom schema. You can also integrate multi-modal datasets into a central Atlas to discover hidden patterns and accelerate research breakthroughs. Terabytes of in-house and public proteomics data can be stored, managed, and analyzed on Polly's secure infrastructure.
• Custom Curation: Polly's harmonization engine provides precise metadata annotation at the dataset, sample, and feature levels. It customizes vocabulary and ontologies for metadata fields, cohorts, and schemas to meet your specific needs, minimizing manual annotation. Our human-in-the-loop AI approach integrates automated tools with expert curation to ensure high-quality metadata. AI algorithms standardize and recommend ontology terms, while human experts validate these terms and conduct thorough QA checks. Transparent methodologies and detailed QA/QC reports ensure the integrity of your data in the Atlas on Polly.
• Proteomics Data Analysis: On Polly, you can analyze and visualize harmonized proteomics data from both in-house and public databases using our pre-configured or custom applications. Furthermore, our experts can support you in leveraging proteomics data to discover biomarkers, identify differentially enriched proteins and pathways, perform functional enrichment analyses, and conduct comprehensive multi-omics analyses. We offer expertise in both horizontal and vertical multi-omics approaches, integrating proteomics with other complementary data types.

By offering cutting-edge tools and services, Elucidata empowers researchers to harness the full potential of proteomics data, driving innovation and breakthroughs in life sciences.
