DAGLA and hepatocellular carcinoma: To further elucidate the molecular mechanism by which the DAGLA/2-AG axis participates in HCC progression, we comprehensively analysed the overlap among the 1619 DEGs (fold change ≥2, P < 0.05) of RNA-seq, 2207 DEGs (fold change ≥ 2, P < 0.05) between HCC and nontumor tissues and 4524 DAGLA-correlated genes (R ≥ 0.3 and P < 0.05) from the TCGA database.
