HDAC6 and colorectal carcinoma: In models of chronic constriction injury (CCI), several regulators have been identified: the C‐type lectin domain containing 7A (Clec7a) (regulated by Levo‐tetrahydropalmatine [l‐THP] in a dose‐dependent manner) [134, 135], histone deacetylase 6 (HDAC6) (inhibited by ACY‐1215) [136], and the Keap1/Nrf‐2/p62 pathway (augmented by carvacrol [CRC] [137] and paeoniflorin [PF]) [138].
