Figure 4. NIH supported research focused on exRNA and exosomes as cancer biomarkers. An advanced text search for (“extracellular RNA” OR exosome OR exRNA OR oncosome) AND cancer AND biomarker was performed on NIH RePORTER (https://projectreporter.nih.gov/reporter.cfm) on 9 May 2020. The text search was limited to project abstracts, project title, and project terms, and was focused on new awards only (excluding subprojects), funded by any NIH Institute or Center from 2010-2020. The search returned 138 projects, which are summarized in Figures 4A and B. A: NIH funded projects were grouped by general funding types; B: NIH funded projects were grouped by general cancer type and the number of projects focused on each cancer type are shown. Projects that did not specify cancer type were grouped together as non-specific cancer
