miR-187 is likely to be involved in many cancer-related processes and characteristics such as sensitivity to drugs, proliferation, apoptosis, invasion, and migration through its regulatory effects on its targets, namely FOXA2, CRMP1, MAD2L2, STOML2, BCL6, PTRF, CYP1B1, FGF9, MAPK12, MAPK7, Bcl-2, IGF-1R [55]. This evidence concerns the gene STOML2 and cancer.
