Fig. 1: Expression profile of lncRNA ANRIL is enhanced in CAD and induced by ox-LDL.

a RNA levels of ANRIL in PBMCs from CAD patients and healthy controls. b, c RNA levels of lncRNA ANRIL in HASMCs treated with ox-LDL, silenced and overexpressed ANRIL measured by qPCR b and FISH stating c. ANRIL in HA **P < 0.01. Antisense probe (AS) of ANRIL was used in FISH, whereas sense probe (S) was included as negative control. CAD, coronary artery disease; HASMC, human aortic smooth muscle cells; FISH, fluorescence in situ hybridization; ox-LDL, oxidized low-density lipoprotein.
