BAP1 and mesothelioma: Importantly, a correlation was found between BAP1 and INO80 expression in mesothelioma, and re-expression of BAP1 in H226 cells exhibiting low levels of INO80 fully rescued the INO80 levels, showing that the low INO80 expression level in H226 cells was due to a lack of BAP1-mediated INO80 stabilization49.
