Tumor necrosis factor alpha-induced protein 2 mRNA 3′-untranslated region (TNFAIP2 mRNA 3′-UTR) (TNFAIP2 mRNA 3′-UTR)

Tumor necrosis factor alpha-induced protein 2 (TNFAIP2) mRNA 3′-untranslated region (3′-UTR) is a critical regulatory segment of the TNFAIP2 transcript, which encodes a protein also known as B94 or M-Sec. This region serves as a hub for post-transcriptional control, containing binding sites for various microRNAs (miRNAs) such as miR-184, miR-155, and miR-146b-3p, which modulate mRNA stability and translational efficiency. Genetic polymorphisms within the 3′-UTR, most notably the rs8126 single nucleotide polymorphism (SNP), have been significantly associated with susceptibility to and prognosis of several malignancies, including head and neck squamous cell carcinoma, esophageal cancer, and gastric cancer. TNFAIP2 itself is a primary response gene induced by TNF-alpha and is involved in diverse cellular processes such as inflammation, angiogenesis, and the formation of tunneling nanotubes (TNTs) for intercellular communication. In oncology, high expression of TNFAIP2 is often linked to increased cell motility, invasion, and resistance to chemotherapeutic agents like cisplatin. Consequently, the TNFAIP2 mRNA 3′-UTR is being explored as a therapeutic target for RNA-based interventions, including antisense oligonucleotides (ASOs) and miRNA mimics, designed to suppress its oncogenic functions and sensitize tumor cells to treatment.

B94 mRNA 3′-UTRM-Sec mRNA 3′-UTRTNFAIP2 3′-UTRTumor necrosis factor alpha-induced protein 2 3′-untranslated region

The TNFAIP2 mRNA 3′-UTR is targeted by microRNAs and antisense agents to induce mRNA degradation or inhibit translation, thereby reducing the expression of the TNFAIP2 protein and its downstream oncogenic and inflammatory signaling.
