Unveiling novel susceptibility genes and drug targets for basal cell carcinoma by a cross-tissue transcriptome-wide
1Department of Pharmacy, Eye & ENT Hospital, Fudan University, Shanghai, China.
Objective:
To identify novel susceptibility genes and drug targets for basal cell carcinoma (BCC).
Methods:
We performed a transcriptome-wide association study (TWAS) to identified the susceptibility genes and potential drug targets for BCC. The cross-tissue TWAS was conducted to discover the candidate genes for BCC. Functional Summary-based Imputation (FUSION) analysis was used to validate these genes in the single tissues. Multimarker Analysis of Genomic Annotation (MAGMA) was employed to further screen candidate genes. Summary data-based Mendelian randomization (SMR) and colocalization analyses were applied to infer causal relationships between candidate genes and BCC. The expression pattern of the identified genes in single-cell types was also investigated. Function, pathway enrichment and disease connection analyses were performed to understand the biological implication of identified genes. Additionally, druggability of the identified genes was evaluated to discover potential candidate drugs for BCC.
Results:
Ninety-five genes were identified by cross-tissue TWAS analysis. Among them, 24 genes were confirmed by FUSION and MAGMA methods. Ten genes were further confirmed by SMR and colocalization analyses. Three genes were replicated by using another GWAS data. The potential interacting gene networks constructed with these identified genes were mainly involved in viral life cycle-HIV-1, GABAergic synapse, nicotine addiction, ether lipid metabolism, and mineral absorption pathways. AN-9 and amooranin might be candidate drugs for BCC.
Conclusions:
We have identified 10 susceptibility genes associated with BCC risk, which might deepen our comprehension of BCC pathogenesis and illuminating new avenues for therapeutic and preventive drug development.
Insights
This study identified 10 novel genes linked to basal cell carcinoma (BCC) risk, offering new therapeutic targets for this common skin cancer. These findings advance understanding of BCC development and potential drug discovery.
Area of Science:
- Genetics
- Oncology
- Pharmacology
Background:
- Basal cell carcinoma (BCC) is the most common human cancer, yet its genetic underpinnings and therapeutic targets remain incompletely understood.
- Identifying novel susceptibility genes and actionable drug targets is crucial for improving BCC management.
Purpose of the Study:
- To discover new genes associated with BCC susceptibility.
- To identify potential drug targets for BCC treatment.
Main Methods:
- A cross-tissue transcriptome-wide association study (TWAS) was performed to identify candidate BCC susceptibility genes.
- Functional Summary-based Imputation (FUSION), Multimarker Analysis of Genomic Annotation (MAGMA), Summary data-based Mendelian randomization (SMR), and colocalization analyses were used for gene validation and causal inference.
- Gene expression patterns, pathway enrichment, and druggability assessments were conducted to understand biological implications and identify potential therapeutic agents.
Main Results:
- Ninety-five candidate genes were initially identified, with 10 ultimately confirmed through multiple analytical methods and replication using independent GWAS data.
- Identified gene networks implicate pathways such as viral life cycle, GABAergic synapse, and lipid metabolism in BCC pathogenesis.
- AN-9 and amooranin emerged as potential therapeutic candidates for BCC.
Conclusions:
- Ten novel susceptibility genes associated with BCC risk were identified, enhancing comprehension of BCC pathogenesis.
- These findings open new avenues for developing targeted therapies and preventive strategies for basal cell carcinoma.
