IMPDH2 and lung cancer: Finally, the overall survival probability was calculated for the 30 patients with primary lung carcinoma who developed BM using IMPDH1 and IMPDH2 expression in the lung cancer tissue (high vs. low expression median cutoff values were 144.72 and 162.75, respectively), and for IMPDH1 and IMPDH2 very high vs. very low expression (1st and 3rd quartiles cutoff values: 116.19 and 185.31, and 114.86 and 210.74, respectively) (Figures S5N–S5P and 5H).
