Cathepsin B mRNA (CTSB mRNA)

Cathepsin B mRNA (CTSB mRNA) is the transcript that encodes Cathepsin B, a member of the C1 family of lysosomal cysteine proteases [NCBI Gene, 2024]. This mRNA is essential for the production of the enzyme responsible for intracellular protein turnover, bone resorption, and the activation of various pro-enzymes [UniProt, P07858]. In many cancers, CTSB mRNA is significantly overexpressed, contributing to the secretion of Cathepsin B into the extracellular space where it degrades the basement membrane and facilitates tumor invasion and metastasis [PubMed, PMID: 15671246]. Additionally, CTSB mRNA levels are linked to neurodegenerative diseases like Alzheimer's, where the encoded protease is involved in the processing of amyloid precursor protein [PubMed, PMID: 16951359]. Therapeutic targeting of CTSB mRNA using RNA interference (siRNA) or antisense oligonucleotides (ASOs) aims to silence the gene expression at the pre-translational level, offering a potential strategy to inhibit tumor progression and neuroinflammation [PubMed, PMID: 15150595]. Current research focuses on improving the delivery and stability of these RNA-based therapeutics to minimize off-target effects and systemic toxicity. Monitoring CTSB mRNA levels serves as a potential biomarker for disease progression and therapeutic efficacy in clinical settings. Overall, it represents a high-value target for precision medicine in oncology and neurology.
