SPARC (Secreted protein, acidic, cysteine-rich) is a glycoprotein that binds to collagen type I and other proteins in the extracellular matrix. It is involved in normal tissue remodeling as it regulates the deposition of extracellular matrix, and also plays a role in neoplastic transformation. It modulates interactions between tumoral cells and the peri-tumoral stroma. Homozygous mutations in SPARC give rise to severe bone fragility in humans. SPARC negatively regulates glucose metabolism in hepatocellular carcinoma (HCC). Overexpression of SPARC inhibited glucose uptake and lactate product through downregulation of key enzymes of glucose metabolism.
