TUBB3 and hepatocellular carcinoma: When tested on Huh7 hepatocellular carcinoma (HCC) cells, the acetylpyrrole‐based hit compounds caused a definite morphological change, with increased βIII‐tubulin (TUBB3) expression, as previously observed with the BET chemical probe JQ1 in NUT midline carcinoma (Filippakopoulos et al., 2010) and breast cancer (Kanojia et al., 2020), respectively, and here reproduced in HCC, again with the use of JQ1.
