Long noncoding RNAs (lncRNAs) are known to regulate the development and
progression of various cancers. However, few lncRNAs have been well characterized
in lung adenocarcinoma (LUAD). Here, we identified the expression profile of
lncRNAs and protein-coding genes via microarrays analysis of paired LUAD tissues
and adjacent non-tumor tissues from five female non-smokes with LUAD. A total of
498 lncRNAs and 1691 protein-coding genes were differentially expressed between
LUAD tissues and paired adjacent normal tissues. A novel lncRNA, LUAD transcript
1 (LUADT1), which is highly expressed in LUAD and correlates with T stage, was
characterized. Both in vitro and in vivo data showed that LUADT1 knockdown
significantly inhibited proliferation of LUAD cells and induced cell cycle arrest
at the G0-G1 phase. Further analysis indicated that LUADT1 may regulate cell
cycle progression by epigenetically inhibiting the expression of p27. RNA
immunoprecipitation and chromatin immunoprecipitation assays confirmed that
LUADT1 binds to SUZ12, a core component of polycomb repressive complex 2, and
mediates the trimethylation of H3K27 at the promoter region of p27. The negative
correlation between LUADT1 and p27 expression was confirmed in LUAD tissue
samples. These data suggested that a set of lncRNAs and protein-coding genes were
differentially expressed in LUAD. LUADT1 is an oncogenic lncRNA that regulates
LUAD progression, suggesting that dysregulated lncRNAs may serve as key
regulatory factors in LUAD progression.
