CCL4 and hepatocellular carcinoma: A similar study was performed in the case of CC chemokines by Jiang et al. [95] where the authors, with the use of ONCOMINE, GEPIA, UALCAN, STRING, WebGestalt, GeneMANIA, TRRUST, DAVID 6.8, LinkedOmics, TIMER, GSCALite, and Open Targets databases, revealed that the transcriptional levels of CCL5, CCL8, CCL11, CCL13, CCL15, CCL18, CCL20, CCL21, CCL25, CCL 26, CCL 27 and CCL28 in HCC tissues were significantly elevated, while CCL2, CCL3, CCL4, CCL14, CCL23 and CCL24 were significantly lowered.
