Experimental factors	Aorta root cryosections (8μm thickness) with the presence of aorta valve cups were prepared by freezing microtome.
Experimental features	For immunohistochemistry analysis, aorta roots were dealt with using specific antibodies against TNF-α, ICAM-1, VCAM-1 and MOMA-2, respectively; For NANA analysis, cryosections were subjected to ligation with FTSC; For LC-MS/MS analysis, NANA was released from aorta by acid hydrolysis and then quantified by LC-MS/MS with precursor to product ion transition of m/z 308.1→86.7.
Data source location	Institute of atherosclerosis, Taishan Medical University, Tai’an, China.
Data accessibility	Data are presented in this article.
