Figure 1. GNPNAT1 transcription level in LUAD. (A) The forest plot shows GNPNAT1 expression level meta-analysis of LUAD tumor tissues and normal tissues in five different LUAD cohorts (LCE). (B) The box plot shows GNPNAT1 mRNA expression levels of LUAD tumor tissues and normal tissues in the TCGA (GEPIA) datasets. (C) The box plot shows GNPNAT1 mRNA expression levels of LUAD tumor tissues and normal tissues in the Garber Lung, Okayama Lung, Selamat Lung, and Hou Lung datasets (Oncomine), respectively.
