B-cell translocation gene 2 mRNA 3' untranslated region (BTG2 mRNA 3'UTR)

The B-cell translocation gene 2 (BTG2) mRNA 3' untranslated region (3'UTR) is a critical regulatory segment of the BTG2 transcript, which encodes a potent tumor suppressor protein involved in cell cycle arrest and apoptosis (Mao et al., 2015, PubMed: 26169101). This region contains multiple binding sites for microRNAs (miRNAs) and RNA-binding proteins that dictate the stability and translational efficiency of the BTG2 message (Mayr, 2017, PubMed: 29101116). In various malignancies, oncogenic miRNAs such as miR-21 or miR-130b frequently target the BTG2 3'UTR to silence its expression, thereby promoting cell proliferation and invasion (Liu et al., 2016, PubMed: 27167194; Zhao et al., 2020, PubMed: 32319659). Consequently, the BTG2 mRNA 3'UTR is an emerging target for therapeutic intervention, where strategies like antisense oligonucleotides or antagomirs are explored to prevent miRNA binding and restore tumor suppressor activity. Understanding the complex regulatory network centered on this 3'UTR is essential for developing precision medicines aimed at reversing the silencing of key growth-inhibitory genes in cancer.
