LEPR and neoplasm: As shown in Figure 2, the expression of leptin receptors, including LEPR (Figure 2A, 1.61 vs. 1.13, and p = 0.046), LEPROT (Figure 2B, 1.42 vs. 1.04, and p = 0.002), LEPROTL1 (Figure 2C, 1.31 vs.1.10, and p = 0.036), were elevated in CP tumor tissue compared to normal brain tissue.
