In primary human aortic valve interstitial cells, qRT-PCR after nuclear/cytoplasmic fractionation and FISH showed that circHIPK3 is primarily cytoplasmic. Functional experiments in AVICs indicated that circHIPK3 inhibited the osteogenic response.
Noncoding RNA regulates the expression of Krm1 and Dkk2 to synergistically affect aortic valve lesions.
