Finally, when examining the role of chemerin in specific cell types of NSCLC, in a group of patients with NSCLC with adenocarcinoma, the expression of retinoic acid receptor responder 2 (RARRES2; chemerin) was identified as a marker for overall and progression-free survival in a seven-gene signature, with increased chemerin levels correlating with improved survival [44]. The gene discussed is RARRES2; the disease is adenocarcinoma.
