In the current research, a higher level of PTGR1 was expressed in NSCLC than in the normal lung tissues by using data mining of four separate lung cancer microarray datasets (Beer Lung, Okayama Lung, Garber Lung, and Hou Lung) in the Oncomine database and qRT-PCR assay. Here, PTGR1 is linked to non-small cell lung carcinoma.
