In addition to VCAN and ACAN, an average of 4.3‐fold increase was detected in 14 sites across fibulin‐2 (FBLN2), a glycoprotein known to be involved in stabilizing the VCAN and ACAN network for growth and metastasis of tumor (Olin et al, 2001; Baird et al, 2013; Fig 3D and Appendix Table S1). The gene discussed is VCAN; the disease is neoplasm.
