CDH2 and glioma: Further, a statistically significant increase in N-cadherin expression was observed in U87 glioma cells (p < 0.01) after treatment with GN/ExF (log2RQ = 0.39 ± 0.09812), rGO/ATS (log2RQ = 0.4 ± 0.09812), and rGO/TUD (log2RQ = 0.41 ± 0.09812), whereas in healthy Hs5 cells (p < 0.0001), it was observed only after rGO/ATS treatment (log2RQ = 0.64 ± 0.09322).
