Neurogenic locus notch homolog protein 1 mRNA (NOTCH1 mRNA) (NOTCH1 mRNA)

Neurogenic locus notch homolog protein 1 (NOTCH1) mRNA is the messenger RNA transcript that encodes the NOTCH1 receptor, a critical mediator of the Notch signaling pathway [1, 2]. This pathway plays a fundamental role in regulating cell fate decisions, including differentiation, proliferation, and apoptosis, during embryonic development and adult tissue homeostasis [1, 4]. In various malignancies, such as T-cell acute lymphoblastic leukemia (T-ALL) and chronic lymphocytic leukemia (CLL), NOTCH1 mRNA is often overexpressed or carries gain-of-function mutations that drive oncogenic signaling [5]. Targeting the mRNA directly using antisense oligonucleotides (ASOs) or small interfering RNAs (siRNAs) represents a therapeutic strategy to downregulate NOTCH1 protein levels and inhibit downstream signaling [3, 4]. For instance, the siRNA SYL116011 has been investigated for ocular conditions like glaucoma by modulating Notch-mediated pathways [3]. However, therapeutic application is complicated by the essential role of Notch signaling in normal tissues, particularly the gastrointestinal tract and hematopoietic system, leading to potential safety concerns like intestinal toxicity [5].

Drugs targeting NOTCH1 mRNA primarily utilize RNA interference (RNAi) or antisense-mediated degradation to reduce transcript levels. siRNAs like SYL116011 trigger the RISC complex to cleave the mRNA [3], while antisense oligonucleotides (ASOs) can induce RNase H-mediated cleavage or sterically block translation [4]. These mechanisms effectively lower the expression of the NOTCH1 receptor protein, thereby dampening the Notch signaling pathway in target cells [5].
