Tumor tissues vary considerably in their microenvironment, and the existence of other cell types can influence the ability of the immune system to infiltrate and attack tumor cells. As promising new therapies evolve, there is an increasing need to identify cancer immunotherapy biomarkers to guide their appropriate application.
NGS can provide careful analysis of the cancer genome, and efficiently assess the tumor microenvironment as a real-time, highly sensitive monitor of immune marker expression in response to tumor growth or treatment. NGS analysis can be used to characterize the immune cell repertoire, identify various cell populations in the microenvironment, and comprehensively quantify gene expression of thousands of targets simultaneously.
RNA analysis may help to identify aspects of the tumor microenvironment that can influence the effectiveness of checkpoint immunotherapies, such as inductive and inhibitory cytokines, and local recruitment of other cell types that can inhibit the T-cell response.
Studies of epigenetic alterations in cancer, such as aberrant methylation and altered transcription factor binding, can provide insight into important tumorigenic pathways. NGS and microarray technologies can detect altered methylation and other epigenetic patterns in cancer.Learn More About Cancer Epigenetics
Cancer researchers need simple-to-use bioinformatics applications to gain insights from tumor microenvironment studies and other complex genomic data. BaseSpace Cohort Analyzer allows biologists and researchers to make important discoveries without specialized bioinformatics skills. The retrospective analysis of clinical trial data can help inform future cancer research and drug development programs.
