LINPS

LINPS provides pre-computed perturbation profiles of causal biological networks derived from drug-induced gene expression changes from the Library of Integrated Cellular Signatures across cancer cell lines.

Key Features:

• Data Integration and Pre-computation: Integrates large-scale drug perturbation gene expression datasets from the Library of Integrated Cellular Signatures and converts them into structured representations for downstream analysis.
• Network Perturbation Amplitudes Analysis: Applies network perturbation amplitudes analysis to quantify how drug treatments alter causal biological networks (CBNs).
• Cancer-cell Specific Profiles: Provides perturbation profiles specific to cancer cell lines, mapping drug-induced gene expression changes onto CBNs relevant to cancer biology.

Scientific Applications:

• Therapeutic Target Identification: Facilitates identification of candidate therapeutic targets by revealing nodes and pathways in CBNs affected by drug perturbations.
• Mechanistic Interpretation of Drug Effects: Enables mechanistic interpretation of drug effects at the network level using drug-induced gene expression changes.
• Prioritization of Treatment Strategies: Supports prioritization of drug repurposing or combination strategies by comparing perturbation amplitudes across CBNs in cancer cell lines.

Methodology:

Converts LINCS drug perturbation gene expression datasets into structured representations of causal biological networks, pre-computes perturbation profiles across cancer cell lines, and quantifies impacts using network perturbation amplitudes analysis.
