Western blot analysis reveals that nerve growth factor protein levels in the explanted, failing human heart are greater than 250% of those in normal donor hearts; in one failing heart the levels of nerve growth factor are greater than 500% of those in normal controls. The bands representing nerve growth factor migrated at approximately 146 kD,* the molecular weight for nerve growth factor.
