MPEG1 and colorectal carcinoma: Specifically, for the study of CRC, Maradonna and collaborators have chosen the Tg(mpeg1:eGFP) transgenic line [60], while Póvoa and colleagues have selected the Tg(mpeg1:mCherry-F) transgenic line and the Tg(mpeg1:mCherry-F; tnfa:eGFP-F), which also showcases TNFa positive cells in green fluorescence [52].
