Area of Science:

• Immunology
• Oncology
• Genomics

Background:

• The tumor microenvironment (TME) significantly influences immune responses and cancer progression.
• Understanding cellular and molecular dynamics in the TME is crucial for effective cancer immunotherapies.
• Transcriptome analysis aids in predicting therapy response and monitoring treatment effects.

Purpose of the Study:

• To present a cost-effective protocol for microarray transcriptome analysis of tumors.
• To enable evaluation of immunotherapy responses by examining broad transcriptional changes.
• To offer an alternative to single-cell RNA sequencing for specific research needs.

Main Methods:

• Protocol development for processing tumors for microarray transcriptome analysis.
• Focus on analyzing broad transcriptional responses rather than single-cell details.
• Utilizing microarray technology for cost-effective gene expression profiling.

Main Results:

• The developed protocol is cost-effective for investigating broad transcriptional responses.
• Microarray analysis provides a viable method for evaluating therapy effects on tumors.
• This approach offers a practical alternative to more complex and expensive techniques.

Conclusions:

• Microarray transcriptome analysis is a valuable tool for studying immunotherapy responses.
• The presented protocol offers a cost-effective solution for broad transcriptional investigations in cancer research.
• This method facilitates a deeper understanding of the tumor microenvironment's role in therapy outcomes.
