KRT18 and hepatocellular carcinoma: It has been found that during HBx-induced-HCC many cellular cytoskeletal genes such as microtubule genes tubulinb 2, tubulinb 3, tubulinb 6, keratin 8 (K-8) and keratin 18 (K-18), acting1 (Actg1) and intermediate filament genes periplakin were dysregulated, As it has been documented that these genes were closely clustered and up regulated in liver tissues [70].
