Prof. Burton B. Yang gave an academic report entitled "Methods to study circular RNA functions" and introduced the research by his team in recent years. Also he explained the regulatory role and mechanism of micro RNA and circ-foxo3 in tumor development and angiogenesis. In addition, Prof. Yang specifically pointed out that only when the amount of CIRC RNA reached a certain level can it play the function of micro RNA sponge in the discussion.
 
   
   
In this academic exchange activity, Prof. Yan not only brought cutting-edge international academic knowledge for teachers and students, but also communicated them with more rigorous scientific attitude and encourage them to think critically in scientific research to modify, supplement and perfect their research programs.
