Non-STING mRNAs with partial complementarity

Non-STING mRNAs with partial complementarity refers to a class of messenger RNA (mRNA) transcripts that are unintentionally targeted by nucleic acid-based drugs, such as antisense oligonucleotides (ASOs) or small interfering RNAs (siRNAs), designed to modulate the STING (Stimulator of Interferon Genes) pathway. These off-target interactions occur when the therapeutic sequence shares sufficient homology with non-target mRNAs to trigger degradation or translational repression, often through RNase H recruitment or the RNA-induced silencing complex (RISC). In the development of STING-directed therapies for conditions like Aicardi-Goutières syndrome or systemic lupus erythematosus, minimizing these interactions is a critical safety priority. Bioinformatics screening and chemical modifications are employed to reduce the affinity for these partially complementary sequences and prevent unintended biological consequences. Consequently, this term describes a safety-related classification of transcripts rather than a therapeutic target.
