Figure 2. Expression levels of PER (period) and CRY (cryptochrome) family members in lung adenocarcinoma (LUAD) patients (GEPIA2), with the q-value cutoff set to 0.01. (A) mRNA expressions of PER1, PER2, PER3, CRY1, and CRY2 in LUAD (red) and normal lung tissues (green). The name of a cancer in green indicates that the mRNA expression of the gene in normal tissues was significantly higher than in cancer tissues. (B) mRNA expressions of PER1, PER2, PER3, CRY1, and CRY2 in LUAD (red) and normal lung tissues (gray). Red stars indicate significant differences in the data.
