In addition, 327 genes that showed correlated expression with TGM2 (Pearson correlation coefficient ≥ 0.3) in the GC cohort from the TCGA (Stomach adenocarcinoma (TCGA, Firehose Legacy, n = 478)) (Table S3) were highly enriched in gene sets associated with inflammation, including IMMUNE_RESPONSE, INFLAMMATORY_RESPONSE and INNATE_IMMUNE_RESPONSE (Table S4), when analyzed with the DAVID bioinformatic resources (http://david.abcc.ncifcrf.gov)21. Here, TGM2 is linked to gastric cancer.
