CRISPeering: Bioengineering the Host Cells through CRISPR-Cas9 Genome Editing System as the Next-Generation of Cell Factories


Mohammad Hossein Morowvat*  


Background: Nowadays, CRISPR-Cas9 genome editing system has become a popular bioengineering-based tool for various applications. Owing to its high-target specificity, efficiency, versatility and simplicity, it has gained attraction as a robust tool for molecular biology research, which unveils the biological functions of unstudied genes. As well as engineering the metabolic pathways. Chinese hamster ovary (CHO) cells, and Escherichia coli, are regarded as the most commonly used expression platforms for industrial-scale production of recombinant proteins. The immergence of CRISPR-Cas9 genome editing system, will promote the current status of expression hosts towards controllable and predictable strains.

Objectives: Here, I present the current status of expression hosts for biopharmaceuticals production. Some major accomplishments in utilization of CRISPR-Cas9 genome editing tool in different prokaryotic and eukaryotic system will be discussed and more importantly the future directions of this newly arrived technology to make the next-generation cell factories with improved or novel properties will be suggested. Besides, the challenges facing with recent patents on this field is discussed as well.

Results and Conclusion: The CRISPR-Cas9 genome-editing tool has been adopted to be utilized in some major expression platforms. CRISPeering has been successfully employed for genome editing in different prokaryotic and eukaryotic host cells. The immergence of systems metabolic engineering, systems biology and synthetic biology will fortify the current situation of CRISPR-Cas9 genome editing system.
