Abstract

Lung cancer is the leading cause of cancer related deaths worldwide. Nonsmall cell lung cancers (NSCLC), the most common histological type of lung cancer, are known to be less well characterized. Long noncoding RNAs are a new class of cancer regulators. Here, we aimed to investigate the effect of lncRNA PLIC11 in NSCLC progression. In our study, we found that PLIC11 was upregulated in lung cancer, particularly in metastatic lung cancer tissues. Overexpression of PLIC11 enhanced cell proliferation, migration, and metastasis in vitro and in vivo. Mechanically, PLIC11 could interact with YY1 and promote PIWIL4 expression by transcription activation. Therefore, PLIC11 upregulation is a potential indicator of aggressive lung cancer, Silencing of PLIC11 has great potential therapeutic strategy in NSCLC.
