Abstract: Lactose is a special component of milk and is closely related to milk yield. The factors of influencing lactose synthesis are extensive. The paper reviews the related genes and cell signaling pathways, including glucose transporters, intracellular catalytic lactose synthesis enzymes, hormones (insulin, prolactin, growth hormone, leptin, glucocorticoid ), cell factors(IGF-Ⅰ,IGF-Ⅱ,EGF) and its main cell signal transduction pathway.

Key words: lactose; glucose transporters; insulin-like growth factor; growth hormone; prolactin; cell signal pathways
