COMPOSITIONS AND METHODS OF USING TYROSINE KINASE INHIBITORS

摘要

The present invention provides compositions and methods of inhibiting tyrosine phosphorylation. In one aspect, a composition includes comprising a low-dosage tyrosine kinase inhibitor, where the low-dosage tyrosine kinase inhibitor decreases tyrosine phosphorylation. In another aspect, a method is described for treating cardiovascular disease or condition associated with a RASopathy having aberrant protein tyrosine phosphorylation. Methods for treating congenital heart disease associated with Noonan or Noonan syndrome with multiple lentigines and decreasing aberrant levels of Protein Zero-Related (PZR) tyrosyl phosphorylation are also described.
