Kruppel-like factor 2 messenger RNA 3' untranslated region (KLF2 mRNA 3'-UTR) (KLF2 mRNA 3'-UTR)

The Kruppel-like factor 2 (KLF2) mRNA 3' untranslated region (3'-UTR) is a critical regulatory segment of the KLF2 transcript that controls the stability and translation of this essential transcription factor (Dekker et al., 2006, PMID: 16530936). KLF2 is primarily expressed in endothelial cells, where it exerts potent anti-inflammatory, anti-thrombotic, and vasoprotective effects by inducing the expression of genes such as endothelial nitric oxide synthase (eNOS) and thrombomodulin (Parmar et al., 2006, PMID: 16373676). The 3'-UTR contains binding sites for various microRNAs, most notably miR-92a, which negatively regulate KLF2 expression under conditions of disturbed blood flow or inflammation, contributing to the development of atherosclerosis (Loyer et al., 2014, PMID: 24403440). Therapeutic strategies targeting this region, such as microRNA inhibitors (antagomirs) like MRG-110, aim to block these inhibitory interactions to restore or enhance KLF2 levels (Abplanalp et al., 2020, PMID: 32513674). By stabilizing KLF2 mRNA and preventing its degradation, these interventions seek to improve vascular health and treat cardiovascular diseases (Wu et al., 2011, PMID: 21441548). This approach represents a novel method of modulating gene expression at the post-transcriptional level for therapeutic benefit.
