Stromal-derived factor-1alpha induces a non-canonical pathway to activate the endocrine-linked Tac1 gene in non-tumorigenic breast cells.

Abstract excerpt

The chemokine Stromal-derived factor-1alpha (SDF-1alpha) interacts with seven transmembrane (TM) G-protein-coupled receptor (GPR), CXCR4. SDF-1alpha is linked to inflammation, chemoattraction, cancer metastasis, and hematopoiesis. Tachykinin (Tac1) peptides bind seven transmembrane (TM), GPR and are involved in tumor promotion. SDF-1alpha regulates Tac1 expression in non-tumorigenic breast cells through a bimodal...
