We then confirmed that mRNA expression of PMEPA1 was higher in tumour than normal tissue in TCGA and GEO database GDS2947 n = 32 P = 0.001 (Figure 1B), GSE31737 n = 40 P < 0.0001 (Figure 1C), GSE41329 n = 10 P = 0.0039 (Figure 1D), GSE32323 n = 17 P = 0.0002 (Figure 1E) and TCGA n = 32 P < 0.001 (Figure 1F), and all the data were from the paired samples. The gene discussed is PMEPA1; the disease is neoplasm.
