title: High resolution two-dimensional protein gel evidence of differential gene expression during Entamoeba encystation.
abstract: As an initial step of investigation into the regulatory mechanisms of encystation in Entamoeba, we compared the protein profiles of newly formed cysts and trophozoites of E. invadens using high resolution two-dimensional PAGE and digitized video image analysis of silver stained gels. A total of 155 proteins unique to trophozoites and a total of 72 proteins unique to cysts were detected. Five of the most prominent cyst specific proteins were identified as candidates for further study. These results imply that extensive changes in gene expression accompany the progression of this parasite through its life cycle.
