Network Pharmacology: Harnessing STRING, STITCH, and Clustering for Cellular Biology
Investigating Potential Drug Targets for Non-small Cell Lung Cancer through STITCH Database Analysis
The aim of this study is to identify potential drug targets and repurposing opportunities by analyzing interactions between key proteins involved in non-small cell lung cancer (NSCLC) pathways, focusing on the inhibition of aberrant signaling in cancer therapy.
- Initial Hypothesis: Targeting key nodes in the Ras, PI3K-Akt, Cell Cycle, p53, and Retinoid signaling pathways may provide effective therapeutic strategies for NSCLC by inhibiting cancer cell proliferation and survival.
This document provides a structured approach to utilizing the STRING and STITCH APIs for retrieving protein-protein and chemical-protein interaction data, enriching the findings of your white paper on drug response assessment in lung cancer, particularly in the context of TP53 and RB1 pathways.

Leveraging STRING Database API Queries to Elucidate Sensitivity and Resistance Mechanisms in Cancer Cells
Understanding the molecular mechanisms underlying cancer cell sensitivity and resistance to targeted therapies is crucial for the development of effective treatments. Protein-protein interaction (PPI) networks provide valuable insights into these mechanisms. This study demonstrates the use of optimized STRING database API queries to investigate key proteins and pathways associated with sensitivity and resistance in cancer cells harboring specific genetic mutations. Five focused queries were designed to explore interactions involving Aurora kinases, CDK4/6, KIF11, the MDM2-TP53 axis, and the RAS-MEK-ERK signaling pathway. The results highlight critical interactions and pathways that may contribute to drug response, emphasizing the significance of integrating PPI data to uncover potential therapeutic targets and enhance our understanding of cancer biology.
