Bachet and coworkers examined miRNA expression profiles in murine NIH3T3 cells expressing either human wild-type KIT, hemizygous KIT mutants del 557–558 (D6) or del 564–581 (D54), heterozygous KIT mutants wild-type/D6 or wild-type/D54 and, for validation purposes, in human GIST samples [104]. This evidence concerns the gene KIT and gastrointestinal stromal tumor.
