Human TREX2 adenoviral particles

The TREX2 gene encodes a 3'-5' exonuclease that plays a crucial role in DNA repair and maintenance. As a member of the DEDDh exonuclease family, TREX2 is involved in processing mispaired or damaged DNA ends, thereby ensuring genomic stability. It is highly conserved across species and expressed in a variety of tissues, highlighting its important biological significance. Studies have shown that TREX2 is involved in error-free DNA repair pathways such as base excision repair (BER) and mismatch repair (MMR), and may regulate immune responses by regulating nucleic acid metabolism. Dysregulation of TREX2 has been associated with genomic instability, autoimmune diseases, and cancer, making it a potential therapeutic target.

Human TREX2 adenoviral particles are genetically engineered viral vectors designed to efficiently deliver the TREX2 gene to target cells for research or therapeutic purposes. These particles take advantage of the high transduction efficiency and broad tropism of adenoviruses to enable stable gene expression in both dividing and non-dividing cells. The adenoviral backbone is modified to ensure safety, usually by deleting essential viral genes (e.g., E1/E3) to prevent replication while maintaining high levels of transgene expression. Human TREX2 adenoviral particles are valuable tools for studying the role of TREX2 in DNA repair, cellular senescence, and cancer biology.
