RASSF1 and malignant mesothelioma: Concordantly, transfection of the plasmid encoding wild type RASSF1A in malignant mesothelioma H28 cell line and lung epithelial A549 (Additional file 1: Figure S2F), decreased significantly not only TNT-1 formation, but also their length and intracellular transfers of mitochondria, compared to the cells transfected with the control plasmid (Fig. 2J-N and Additional file 1: Figure S2E).
