IGF2 adenovirus

The insulin-like growth factor 2 (IGF2) gene encodes a peptide hormone critical for fetal growth, cell proliferation, and tissue development. As a member of the insulin-like growth factor family, IGF2 shares a similar structure to insulin and plays a key role in regulating metabolism, particularly during the embryonic stage. It is primarily expressed during pregnancy, promoting placental and fetal growth by binding to the IGF1 receptor (IGF1R) and the insulin receptor (IR). Dysregulation of IGF2 is associated with a variety of diseases, including Beckwith-Wiedemann syndrome (characterized by overgrowth) and certain cancers, where its overexpression can promote tumor progression.

The IGF2 adenovirus is a recombinant viral vector designed to deliver the IGF2 gene to target cells, leveraging the high transduction efficiency and broad tissue tropism of adenovirus. Adenovirus vectors are favored in gene therapy because they can infect both dividing and non-dividing cells, ensuring stable transgene expression. Designed to overexpress IGF2 in specific tissues, the IGF2 adenovirus has potential applications in treating conditions such as muscle atrophy, cardiac regeneration, and diabetic ulcers. Preclinical studies have demonstrated its effectiveness in enhancing tissue repair and modulating metabolic pathways.
