CRISPR/Cas9-induced disruption of Bodo saltans paraflagellar rod-2 gene reveals its importance for cell survival

Donna Huber on January 31, 2022

Developing transfection protocols for marine protists is an emerging field that will allow the functional characterization of protist genes and their roles in organism responses to the environment. We developed a CRISPR/Cas9 editing protocol for Bodo saltans, a free-living kinetoplastid with tolerance to both marine and freshwater conditions, and a close non-parasitic relative of trypanosomatids. …

A CRISPR/Cas9-riboswitch-Based Method for Downregulation of Gene Expression in Trypanosoma cruzi

Donna Huber on February 27, 2020

Few genetic tools were available to work with Trypanosoma cruzi until the recent introduction of the CRISPR/Cas9 technique for gene knockout, gene knock-in, gene complementation, and endogenous gene tagging. Riboswitches are naturally occurring self-cleaving RNAs (ribozymes) that can be ligand-activated. Results from our laboratory recently demonstrated the usefulness of the glmS ribozyme from Bacillus subtilis, which has been shown to …

Genome Editing by CRISPR/Cas9 in Trypanosoma cruzi

Donna Huber on March 15, 2019

The genetic manipulation of the human parasite Trypanosoma cruzi has been significantly improved since the implementation of the CRISPR/Cas9 system for genome editing in this organism. The system was initially used for gene knockout in T. cruzi, later on for endogenous gene tagging and more recently for gene complementation. Mutant cell lines obtained by CRISPR/Cas9 have been …
