Abstract: Giardia lamblia is an important human pathogen that causes diarrhea and malnutrition. As a late-branching eukaryote, G. lamblia may have special mechanisms for regulating gene expression which differ from other eukaryotes. In this paper, the mechanisms that governing regulation of G. lamblia gene expression, such as promoters, transcription factors, transcriptional regulation, translation initiation and epigenetic mechanisms are summarized.

Key words: Giardia lamblia, Gene Expression, Regulation
