Task: Answer Verification
Input (English): Question: Does glycyrretinic acid block cardiac sodium channels expressed in Xenopus oocytes?
Answer: GA blocked cardiac sodium currents, particularly late I(Na.) Our findings might help to understand the traditional use of licorice in the treatment of cardiovascular disorders, because reduction of sodium currents (particularly late I(Na)) would be expected to provide protection from Na(+)-induced Ca(2+) overload and cell damage.
Output (English): yes
