Aldehyde dehydrogenase 1 family member A1, also known as ALDH1A1 is an enzyme that in humans is encoded by the Aldh1A1 gene on chromosome 9. ALDH1A1 belongs to the aldehyde dehydrogenase family, which plays a role in alcohol metabolism. There are two major aldehyde dehydrogenase isozymes in the liver; cytosolic and mitochondrial. The ALDH1A1 gene encodes the cytosolic isozyme, and catalyzes the oxidation of retinaldehyde to retinoic acid. Studies have indicated that ALDH1A1 may also be involved in the regulation of the metabolic responses to high-fat diet. ALDH1A1 has been a well established marker of hematopoietic stem cells and progenitor cells. Recent studies also show that ALDH1A1 is an important cancer stem marker associated with tumor progression in cancers of the breast, prostate and lung. This antibody labels epithelial cells of the stomach, liver, kidney and thyroid, neural cells and stromal cells including endothelial cells. In tumors, it stains stromal cells as well as tumor cells in many types of cancers. ALDH1A1 can be used with CD34 to aid in the differentiation between solitary fibrous tumors, hemangiopericytoma, meningioma and synovial sarcomas.
