Caspase-3 messenger RNA 3' untranslated region (CASP3 mRNA 3'UTR) (CASP3 mRNA 3'UTR)

The Caspase-3 messenger RNA 3' untranslated region (CASP3 mRNA 3'UTR) is a critical regulatory segment of the CASP3 transcript that governs the expression of the executioner caspase-3 protein (UniProt P42574). This region contains multiple binding sites for microRNAs (miRNAs) and RNA-binding proteins, which collectively modulate mRNA stability and translation efficiency (NCBI Gene ID: 836). In many cancers, overexpression of oncogenic miRNAs like miR-21 targets this 3'UTR to suppress Caspase-3 production, thereby facilitating apoptosis evasion and chemoresistance (Zhu et al., 2008, Cell Research; PMID: 18443608). Conversely, in neurodegenerative conditions or acute injuries like stroke, the dysregulation of this region can lead to pathological overexpression of Caspase-3, driving excessive cell death (PubMed: 21471066). Therapeutic strategies targeting the CASP3 mRNA 3'UTR include the use of antisense oligonucleotides (ASOs) or miRNA mimics to either restore or inhibit Caspase-3 levels depending on the disease context (NCBI PMC: PMC3921586). While promising, these approaches face challenges such as ensuring tissue-specific delivery and minimizing off-target effects on other mRNA transcripts that share similar regulatory sequences (Nature Reviews Drug Discovery, 2020).
