Figure 1. Pro-invasive factors within brain tumor microenvironment.

Figure 1

(A) Schematic illustration of brain tumor-favorable microenvironment. Hyaluronic acid (HA)-rich extracellular matrix (ECM) and pre-existing brain anatomy (e.g. white matter tract). (B) Illustration of three major components in HA metabolism. Transcriptomic analysis of Gene Expression Omnibus (GEO) data for three major HA metabolic genes between normal brain tissue and GBM tissue: HA receptors (CD44, RHAMM), HA Synthases (HAS1, HAS2, and HAS3), and Hyaluronidase (HYAL1, HYAL2, HYAL3, and HYAL4). The normalized gene expression ranging from 0 (no expression) and 1 (fully expression). Red bar indicates the statistical significance between normal and GBM tissue.
