Proteomics

7.2K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Protein Networks

3.9K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Area of Science:

  • Clinical proteomics
  • Bioinformatics
  • Medical imaging analysis

Background:

  • Proteomics is vital for clinical research, but applying proteomic data is difficult.
  • Deep learning (DL) on mass spectrometry-red, green, and blue (MS-RGB) images can improve analysis, but current models miss key features.

Purpose of the Study:

  • To develop an advanced deep learning framework, ProteoNet, for enhanced analysis of MS-RGB data.
  • To improve the accuracy and efficiency of clinical proteomics data interpretation.

Main Methods:

  • Developed ProteoNet, a deep learning framework integrating semantic partitioning, adaptive average pooling, and weighted factors into a Convolutional Neural Network (CNN).
  • Implemented a direct conversion method for transforming mass spectrometry (MS) data into MS-RGB image formats.
  • Tested ProteoNet on proteomics data from urine, blood, and tissue samples for liver, kidney, and thyroid diseases.

Main Results:

  • ProteoNet demonstrated superior accuracy compared to existing models in analyzing MS-RGB data from various clinical samples.
  • The framework successfully extracts subtle, crucial features from MS-RGB data, leading to improved analytical performance.
  • ProteoNet showed compatibility with diverse CNN architectures, including MobileNetV2, indicating scalability.

Conclusions:

  • ProteoNet offers a significant advancement in the clinical application of proteomics by refining MS-RGB data analysis.
  • The framework's accuracy, efficiency, and scalability highlight its potential for widespread clinical adoption.
  • ProteoNet facilitates a seamless workflow from MS data to actionable insights for disease diagnosis and research.
