HMMR and cancer: Upon examining the expression levels of 2 additional HA receptors, RHAMM (encoded by the Hmmr gene) and LYVE-1 (encoded by the Lyve1 gene), we found that LYVE-1 expression was also elevated in mesenchymal cancer cells, whereas RHAMM expression was slightly higher in epithelial cancer cells (Supplemental Figure 6J).
