RASSF1 and mesothelioma: The analysis of the different native lung epithelial and mesothelioma cell lines, as the analysis of lung and mesothelial cells upon RASSF1A silencing, or conversely re-expression pointed out the preferential formation of TNT-1 in RASSF1A-depleted cells, compared to cells with normal RASSF1A expression (Fig. 2).
