Published Data

Technology: Knockout of sialidase and pro-apoptotic genes in Chinese hamster ovary cells.

Journal: Metabolic Engineering

IF: 8.829

Published: 2019

Results: The authors used a CRISPR/cas9-mediated large deletion approach to knock out three sialidase genes (Neu1, 2, and 3) in the recombinant Chinese hamster ovary (rCHO) cell line that produces recombinant human erythropoietin. The results indicate that knockout of sialidase and pro-apoptotic genes in rCHO cells is a useful tool for generating large amounts of sialylated glycoproteins in fed-batch mode.

Here are some of the results shown in this article:

Applications

Cancer immunotherapy: By modifying the glycan structures on the surface of cancer cells, researchers make these cells more recognizable to the immune system. This enhances the immune system's ability to target and destroy cancer cells.
Vaccine development: By manipulating the glycan structures on the surface of pathogenic microbes or viruses, researchers can create attenuated strains for vaccine development. This gene knockout-based approach enhances the immune response and improves the efficacy of vaccines.
Stem cell therapies: Modifying the glycan profiles on the surface of stem cells improves their ability to integrate into host tissues and avoid immune rejection. This is particularly relevant in regenerative medicine and tissue engineering.
Drug target identification: Gene knockout-based glycoengineering aids in the identification of cell surface glycoproteins that serve as drug targets. By selectively modifying the glycans on cell surfaces, researchers investigate how changes in glycan structures affect the function and interactions of specific proteins. This leads to the discovery of new drug targets and the development of targeted therapies.
