Role of gamma-giardin in ventral disc formation of Giardia lamblia.

ABSTRACT:

Background

Giardia lamblia, a protozoan pathogen causing diarrheal outbreaks, has characteristic cytoskeletal structures including eight flagella, a median body and a ventral disc. Gamma-giardin is a unique component protein of the cytoskeleton of this protozoan.

Results

Through comparative proteomic analysis between different stages of the cell cycle, G. lamblia γ-giardin (Glγ-giardin) was identified as an upregulated protein in the G2-phase. Increased Glγ-giardin expression in G2 was confirmed by western blot and real-time polymerase chain reaction analyses. Knockdown of this protein using a morpholino affected the formation of ventral discs, especially the microribbons of the discs, but exerted little effect on the binding ability of G. lamblia. The number of cells with f
