May 18, 2018 · Triple-negative breast cancer (TNBC) is a highly metastatic subtype of breast cancer that has limited therapeutic options. Thus, developing novel treatments for metastatic TNBC is an urgent need. Polymer Solubility and Solubility Parameter Solubility parameters were initially developed to guide solvent selection in the paint and coatings industry. Today, they are widely used in in many other fields to predict miscibility and solubility of polymers, chemical resistance, and permeation rates.

Heat shock protein 70 is a molecular chaperone that, without ATP, can bind denatured proteins and maintain their solubility, while ATP hydrolysis is required to facilitate folding of nascent or denatured proteins (O'Brien et al, 1996; Ohno et al, 2004). If nascent or denatured polypeptides cannot be folded successfully, they must be degraded by ...
