Figure 2. Expression of ID family members in lung cancer in the GEPIA database.

(A) Expression profile of ID family members in lung cancer. Red trace, tumor samples; green trace, normal samples. (B) Boxplot results of the expression levels of ID family members in lung cancer. A t-test was used to compare the expression level differences between tumor and normal tissues (P < 0.01). Y-axis represents log₂(TPM+1). Red box, tumor samples; green box, normal samples. T, tumor; N, normal; LUAD, lung adenocarcinoma; LUSC, lung squamous cell carcinoma; ID, inhibitor of differentiation/DNA-binding.
