Abstract

- Rare diseases are, despite their name, collectively common and millions of people are affected daily of conditions where treatment often is unavailable. Sulfatases are a large family of activating enzymes related to several of these diseases. Heritable genetic variations in sulfatases may lead to impaired activity and a reduced macromolecular breakdown within the lysosome, with several severe and lethal conditions as a consequence. While therapeutic options are scarce, treatment for some sulfatase deficiencies by recombinant enzyme replacement are available. However, such recombinant production of sulfatases suffers greatly from low product activity and yield, further limiting accessibility for patient groups. Here, we have addressed this problem by defining key-proteins necessary for active sulfatase secretion by comparison of CHO clones with different levels of production of active sulfatase. Quantitative transcriptomic analysis highlighted 14 key genes associated with sulfatase production, and experimental validation by co-expression improved the sulfatase enzyme activity by up to 150-fold. Furthermore, a correlation between product mRNA levels and sulfatase activity were observed and expression with lower activity promoters showed an increased in sulfatase activity. The workflow devised is general and we propose it to be useful for resolving bottlenecks in cellular machineries for improvement of cell factories for other biologics as well.
