Further analysis revealed that the lncRNA ADAMTS9-AS2 interacted with mRNAs related to both calcium function and cell junction function, highlighting the importance of both in AF men, and particularly those deficient in vitamin D. Taken together, these results suggest the lncRNAs AC007743.1, ADAMTS9-AS2, LINC01001, and PCA3 are regulated by supplementation and are important in AF men deficient in vitamin D. LINC01001 was the second-ranked central lncRNA in AF men. The gene discussed is LINC01001; the disease is atrial fibrillation.
