Transcriptome Analysis of Encystation in Entamoeba invadens
Encystation is an essential differentiation process for the completion of the life cycle of a group of intestinal protozoa including Entamoeba histolytica, the causative agent of intestinal and extraintestinal amebiasis. However, regulation of gene expression during encystation is poorly understood. To comprehensively understand the process at the molecular level, the transcriptomic profiles of...
متن کاملChitin synthase in encysting Entamoeba invadens.
Although the cyst wall of Entamoeba invadens contains chitin, synthesis of this structural polymer during encystation has not been described before. Here we report that conditions which stimulate encystation of the parasite lead to increased chitin synthase (ChS) activity, measured by incorporation of [3H]GlcNAc ([3H]N-acetylglucosamine) from UDP-GlcNAc. The radiolabelled product was precipitab...
متن کاملImmunocytochemical Reactions in the Brittle-Star: Ophiocomina Nigra after Immunization
Submit Manuscript | http://medcraveonline.com system. Immunocytochemical positive reactions were observed in 1973 in the sea star Asterina gibbosa (Asterid, Echinoderm) after injections of various proteins [1]. It seemed interesting to look for similar reactions in the Ophuirid: Ophiocomina nigra (another echinoderm) which possesses also an axial organ. The sea star axial organ, an ancestral ly...
متن کاملIsolation of Ribosomes from Cysts of Entamoeba Invadens
A reproducible method for the preparation of 75S ribosomes from cysts of Entamoeba invadens is presented. The method depends on the inactivation of the cyst's ribonuclease by high levels of Bentonite. The ribosomes are found to be extremely sensitive to ribonuclease, and to be stabilized by the addition of manganous and calcium ions to the magnesium customarily employed. Reasons are given for e...
متن کاملActin, RhoA, and Rab11 Participation during Encystment in Entamoeba invadens
In the genus Entamoeba, actin reorganization is necessary for cyst differentiation; however, its role is still unknown. The aim of this work was to investigate the role of actin and encystation-related proteins during Entamoeba invadens encystation. Studied proteins were actin, RhoA, a small GTPase involved through its effectors in the rearrangement of the actin cytoskeleton; Rab11, a protein i...
