Stromal cell-derived factor 1 (CXCL12) messenger RNA (CXCL12 mRNA)

Stromal cell-derived factor 1 (SDF-1), also known as CXCL12, is a potent chemoattractant cytokine belonging to the CXC chemokine family (UniProt P48061). The CXCL12 mRNA serves as the template for the synthesis of this protein, which plays a critical role in various biological processes including hematopoiesis, vascularization, and the homing of hematopoietic stem cells to the bone marrow. In therapeutic contexts, CXCL12 mRNA is being investigated as a tool for regenerative medicine, where modified mRNA (modRNA) is delivered to ischemic tissues, such as the heart after a myocardial infarction, to transiently express the protein and recruit reparative cells (Zangi et al., 2013). Conversely, silencing CXCL12 mRNA using RNA interference (RNAi) is a strategy explored in oncology to disrupt the CXCL12/CXCR4 signaling axis, which is frequently hijacked by cancer cells to promote survival, angiogenesis, and metastasis (PubMed: 25608577). The dual role of the encoded protein in both tissue repair and disease progression necessitates precise control over mRNA delivery and expression levels. Because the CXCL12/CXCR4 axis is also involved in HIV entry and inflammatory diseases, modulating its mRNA levels offers a versatile approach to treating a wide range of conditions. Current research focuses on optimizing the stability and delivery of these mRNA-based agents to ensure efficacy while minimizing potential side effects like unwanted inflammation or tumor promotion.
