NLRP7 mRNA levels did not differ significantly between 30 CRC tissues and normal colorectal mucosa by qRT-PCR (Fig. 1a), and was confirmed by analysis of gene expression from the GEO dataset (GSE23878, GSE32323, GSE110223, GSE156355) (Additional file 3: Fig. S1A). The gene discussed is NLRP7; the disease is colorectal carcinoma.
