Antagomirs, also known as anti-miRs, are a class of chemically engineered oligonucleotides designed to silence endogenous microRNAs (also known as miRNAs or miRs).[1][2][3]
Antagomirs are a kind of antisense oligonucleotide, as their sequence is complementary to their specific miRNA target. Their structure has modifications so as to make them more resistant to degradation. These include 2'-methoxy groups on the ribose sugar, backbones with phosphorothioate bonds, and cholesterol conjugation on the 3' end.[4]
