Posted by & filed under Part 14: METALS, Treatment.

Chaperones such as phenylbutyrate and curcumin can be used to treat conditions with misfolded proteins such as ATP7 in Wilson Disease.

Hepatology. 2009 Dec;50(6):1783-95.

Phenylbutyrate also has other pharmacological effects, such as HDAC inhibition,  ↓ stability of HSC70 mRNA leading to ↓ degradation of ΔF508 CFTR, ↑ PPARG activation, isoprenylation inhibition, and ↓ methylation. These properties render it an attractive compound for the treatment of other genetic conditions such as cystic fibrosis and thalassemias.
