Long non-coding (lnc) RNAs serve a multitude of functions in cells. NEAT1 RNA is a highly abundant 4 kb lncRNA in nuclei, and coincides with paraspeckles, nuclear domains that control sequestration of paraspeckle proteins. We examined NEAT1 RNA levels and its function in 3T3-L1 cells during differentiation to adipocytes. Levels of NEAT1 transcript, measured by RT-PCR, fluctuated in a temporal m...
OBJECTIVE Breast cancer (BC) is one of the most common cancers in females. Abnormal proliferation and metastasis are key reasons that cause mortality in BC patients. More and more evidence showed that lncRNA played an important role in the BC development, but the mechanism was not well established. PATIENTS AND METHODS The expression of lncRNA NEAT1 was detected in 40 BC patients by qRT-PCR t...
A number of studies have revealed that nuclear paraspeckle assembly transcript 1 (NEAT1), a long noncoding RNA (lncRNA), was aberrantly regulated in various cancers. High NEAT1 expression was associated with a poor prognosis and an increased risk of lymph node metastasis (LNM) in cancer patients. This meta-analysis was conducted to identify the potential value of NEAT1 as a biomarker for cancer...
The altered expression of long non-coding RNAs (lncRNAs) is often related to carcinogenesis, metastasis and resistance to radiation or chemotherapy. In the current study, cDNA microarray analysis found that NEAT1 expression was reduced in nasopharyngeal carcinoma (NPC) patients and that it regulated NPC progression. However, the detailed mechanisms of NEAT1 in NPC were unclear. NEAT1 repressed ...
Neat1 is a non-protein-coding RNA that serves as an architectural component of the nuclear bodies known as paraspeckles. Although cell-based studies indicate that Neat1 is a crucial regulator of gene expression, its physiological relevance remains unclear. Here, we find that Neat1 knockout (KO) mice stochastically fail to become pregnant despite normal ovulation. Unilateral transplantation of w...

Nuclear paraspeckles are built co-transcriptionally around a long non-coding RNA, NEAT1. Here we report that transfected 20-mer phosphorothioate-modified (PS) antisense oligonucleotides (ASOs) can recruit paraspeckle proteins to form morphologically normal and apparently functional paraspeckle-like structures containing no NEAT1 RNA. PS-ASOs can associate with paraspeckle proteins, including P5...
Despite their abundance, the molecular functions of long non-coding RNAs in mammalian nervous systems remain poorly understood. Here we show that the long non-coding RNA, NEAT1, directly modulates neuronal excitability and is associated with pathological seizure states. Specifically, NEAT1 is dynamically regulated by neuronal activity in vitro and in vivo, binds epilepsy-associated potassium ch...
Recently, the long non-coding RNA (lncRNA) NEAT1 has been identified as an oncogenic gene in multiple cancer types and elevated expression of NEAT1 was tightly linked to tumorigenesis and cancer progression. However, the molecular basis for this observation has not been characterized in progression of non-small cell lung cancer (NSCLC). In our studies, we identified NEAT1 was highly expressed i...
Background This study aims to evaluate the diagnostic value of nuclear-enriched abundant transcript 1 (NEAT1) expression in peripheral blood mononuclear cells (PBMCs) for the early diagnosis of sepsis. Methods A total of 59 patients with sepsis, 52 noninfectious SIRS patients, and 56 healthy controls were recruited fort this study. The levels of NEAT1 expression in PBMCs were measured using q...
