• For Instance, according to the data published by Centers for Disease Control and Prevention, an estimated 129 million people in the U.S. have at least 1 major chronic disease (eg, heart disease, cancer, diabetes, obesity, hypertension) as defined by the U.S. Department of Health and Human Services. An increasing proportion of people in America are dealing with multiple chronic conditions; 42% have 2 or more, and 12% have at least 5.

Restraints:

Difficulties in Expressing Post-Translational Modifications could constrain the Market

The inability to achieve appropriate post-translational modifications (PTMs), such as glycosylation, phosphorylation, or disulfide bond formation, which are essential for the biological activity, stability, and function of many therapeutic proteins, is a significant obstacle in protein production. These changes are frequently impossible for prokaryotic systems, such as E. coli, which results in proteins that are unstable or inert.

• Counterbalance Statements: Using eukaryotic expression systems, consisting of yeast or mammalian cells, which have the cellular machinery to do intricate PTMs, is the answer. Furthermore, scientists can alter less complex hosts to resemble eukaryotic PTMs thanks to developments in synthetic biology and genetic engineering, which enhances the caliber and functionality of the proteins that are expressed.

Opportunities & Trends:

Future Market Opportunities can be Revealed by the Growing Interest in Precision and Personalized Medicine
