Epigenetics Drug

Epigenetics & Drug Response

Discipline: Epigenetic Pharmacology | Tools Used: 4 | Servers: 3

Description

Link epigenetics to drug response: gene regulation, variant effects, drug interactions, and expression.

Tools Used

• get_overlap_region from ensembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl
• get_vep_hgvs from ensembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/12/Origene-Ensembl
• get_drug_interactions_by_drug_name from fda-drug-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/14/Origene-FDADrug
• get_gene_expression_across_cancers from tcga-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/11/Origene-TCGA

Workflow

1. Get regulatory overlap
2. Predict variant effects
3. Check drug interactions
4. Analyze gene expression

Test Case

Input

{
    "region": "7:140753336-140753436",
    "drug": "vemurafenib",
    "gene": "BRAF"
}

Expected Steps

1. Get regulatory overlap
2. Predict variant effects
3. Check drug interactions
4. Analyze gene expression

Usage Example

Note: Replace <YOUR_SCP_HUB_API_KEY> with your own SCP Hub API Key. You can obtain one from the SCP Platform.
