Insights

This study uses proteomic network analysis across seven cancers to identify key cancer pathways and regulators. It reveals conserved protein modules and validates new therapeutic targets like RSL1D1, DDX21, and SMC2.

Area of Science:

  • Proteomics
  • Systems Biology
  • Cancer Research

Background:

  • Global proteomic data from mass spectrometry (MS) can elucidate cancer functional models.
  • Integrative proteomic network analyses were performed on 687 cases across 7 cancer types.

Discussion:

  • Protein co-expression network analysis identified disease-associated pathways.
  • Comparison with transcriptome networks revealed proteome-specific cancer subnetworks.
  • Cross-cancer analysis identified conserved protein modules and central functional axes: ERAD and N-acetyltransferase activity.

Key Insights:

  • Developed interpretable network models of cancer proteomes.
  • Identified novel pan-cancer protein regulators (RSL1D1, DDX21, SMC2) for disease-associated pathways.
  • Experimental validation confirmed the role of predicted regulators in various cancer and fetal cells.

Outlook:

  • Proteomic network models offer potential for discovering oncogenic regulators.
  • This approach can elucidate cancer mechanisms and identify new therapeutic targets.
  • Further research can leverage these models for precision oncology.

Protein Networks

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,...

Protein-protein Interfaces02:04

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
