To further investigate whether ADARB1 expression is associated with the chemosensitivity of glioma cells, we used Spearman’s rank correlation method to examine the correlation between ADARB1 expression and TMZ sensitivity (IC50) in 5 glioma cell lines (U343, Hs683, U251, U118, and T98G). The gene discussed is ADARB1; the disease is glioma.
