MUC1 is a multifunctional cell surface glycoprotein that modulates cell adhesion, protects mucosa from infection and enzymatic attack, lubricates cell surfaces, participates in multiple signal-transduction pathways and is overexpressed by many tumors. MUC1 levels change dynamically in various cellular contexts. The primary mechanism for controlling MUC1 expression appears to be transcriptional through a complex combination of often overlapping regulatory motifs that control both tissue specificity and overall rate of transcription. This review will summarize the current knowledge of the factors known to control MUC1 transcriptional regulation, including cytokines, steroid hormones and the growth factors they stimulate, as well as suggest how this information may be exploited in the future to control MUC1 expression in specific biological contexts.
