Trang et al. and Ai et al. both reported that delivery of synthetic mimics of suppressor miRNAs in complex with a novel neutral lipid emulsion by blood stream was preferentially targeted to lung tumors and showed remarkable inhibition of tumors in a V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS)-driven mouse models of lung cancer [141,142]. This evidence concerns the gene KRAS and lung carcinoma.
