CCNB1 and non-small cell lung carcinoma: As shown in Figure 6(b), we demonstrated that PTGR1 was positively correlated with CDK2 (r2 = 0.12, p = 0.02), cyclin A2 (r2 = 0.28, p < 0.001), CDK1 (r2 = 0.11, p = 0.03), and cyclin B1 (r2 = 0.19, p = 0.003), suggesting a possible mechanism of how PTGR1 affected the development and progress of NSCLC.
