In summary, exosomal LINC00461 has a sponge effect on miR-15a/16, affecting the expression of downstream genes such as CABIN1 mRNA, VEGFA, and BCL2, and forming a ceRNA regulatory network centered on LINC00461-miR-15a/16, thereby influencing MM proliferation, invasion, and apoptosis. The gene discussed is VEGFA; the disease is Miyoshi myopathy.
