RE1-silencing transcription factor mRNA 3′ untranslated region (REST mRNA 3′UTR)

The RE1-silencing transcription factor (REST) mRNA 3′ untranslated region (3′UTR) is a critical regulatory segment that controls the post-transcriptional expression of the REST protein, a master repressor of neuronal genes (Chong et al., 1995). REST, also known as the neuron-restrictive silencer factor (NRSF), plays a vital role in maintaining neuronal identity and protecting neurons from various stressors (Lu et al., 2014). The 3′UTR contains multiple microRNA response elements (MREs) that serve as binding sites for miRNAs such as miR-124, miR-9, and miR-153-3p, which regulate REST levels by inducing mRNA degradation or inhibiting translation (Rivera et al., 2023). Dysregulation of this 3′UTR-mediated control is linked to several neurodegenerative diseases, including Alzheimer's disease and amyotrophic lateral sclerosis (ALS), where altered REST levels contribute to neuronal loss (Wang et al., 2024). Additionally, the REST mRNA 3′UTR is involved in oncogenesis, particularly in brain tumors like glioblastoma, where REST can act as an oncogene (Jin et al., 2023). Therapeutic interventions targeting this region, such as miRNA mimics or antisense oligonucleotides, aim to modulate REST expression to restore cellular homeostasis. These RNA-based strategies represent a promising frontier for treating complex neurological and malignant conditions by fine-tuning the expression of this essential transcription factor.
