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]. The gene discussed is MAD2L2; the disease is cancer.
