Nuclear Factor Y (NF-Y) Modulates Encystation in Entamoeba via Stage-Specific Expression of the NF-YB and NF-YC Subunits

Abstract

The human parasite Entamoeba histolytica is an important pathogen with significant global impact and is a leading cause of parasitic death in humans. Since only the cyst form can be transmitted, blocking encystation would prevent new infections, making the encystation pathway an attractive target for the development of new drugs. Identification of the genetic signals and transcriptional regulatory networks that control encystation would be an important advance in understanding the developmental cascade. We show that the Entamoeba NF-Y complex plays a crucial role in regulating the encystation process in Entamoeba .
