LRG1 is a secreted glycoprotein that is abundantly present in the microenvironment of many tumors, where it contributes to vascular dysfunction . The recombinant form of LRG1, produced in Sf9 Baculovirus cells, is a single, glycosylated polypeptide chain containing 321 amino acids and has a molecular mass of 35.4 kDa . This recombinant protein is expressed with a 6-amino acid His tag at the C-terminus and is purified using proprietary chromatographic techniques .
LRG1 plays a significant role in various physiological and pathological processes. It is constitutively expressed by hepatocytes and neutrophils, and its expression is induced in response to various inflammatory stimuli . LRG1 has been implicated in multiple human conditions, including cancer, diabetes, cardiovascular disease, neurological disease, and inflammatory disorders .
One of the key functions of LRG1 is its involvement in the TGFβ signaling pathway, where it acts as an upstream modifier . This pathway is crucial for regulating cell growth, differentiation, and immune responses. LRG1’s modulation of TGFβ signaling can lead to various effects on different cell types, including epithelial, immune, mesenchymal, and cancer cells .
LRG1 has been identified as a pathogenic factor in several diseases. It disrupts the cellular interactions required for the formation and maintenance of mature blood vessels, contributing to a highly hypoxic and immunosuppressive microenvironment . This vasculopathic role of LRG1 makes it a potential therapeutic target for diseases characterized by abnormal vascular function.
In cancer, LRG1 is present abundantly in the tumor microenvironment, where it impedes the delivery of therapeutics by contributing to vascular dysfunction . The development of antibody-drug conjugates (ADCs) targeting LRG1 has shown promise in improving the efficacy of cancer treatments .
Given its role in disease pathogenesis, LRG1 is being explored as a therapeutic target. Inhibition of LRG1 through gene deletion or function-blocking antibodies has been shown to attenuate disease progression in animal studies . This suggests that targeting LRG1 could be a viable strategy for treating various diseases, including cancer and inflammatory disorders.
