PTGR1 and neoplasm: As shown in Supplementary Figure 1, in Supplementary Material available online at http://dx.doi.org/10.1155/2016/5230642, PTGR1 was significantly increased in tumor tissues (n = 10, p = 0.0346) compared with the paired adjacent tissues (n = 10), which showed that consistent overexpression of PTGR1 in NSCLC tumors indicated that PTGR1 played a potential role in the carcinogenesis of the lung.
