摘　　要：Congenital heart disease(CHD)is the most common birth defect worldwide.Long non-coding RNAs(lncRNAs)have been implicated in many diseases.However,their involvement in CHD is not well understood.This study aimed to investigate the role of dysregulated lncRNAs in CHD.We used Gene Expression Omnibus data mining,bioinformatics analysis,and analysis of clinical tissue samples and observed that the novel lncRNA SAP30-2:1 with unknown function was significantly downregulated in damaged cardiac tissues from patients with CHD.Knockdown of lncRNA SAP30-2:1 inhibited the proliferation of human embryonic kidney and AC16 cells and decreased the expression of heart and neural crest derivatives expressed 2(HAND2).Moreover,lncRNA SAP30-2:1 was associated with HAND2 by RNA immunoprecipitation.Overall,these results suggest that lncRNA SAP30-2:1 may be involved in heart development through affecting cell proliferation via targeting HAND2 and may thus represent a novel therapeutic target for CHD.
