The roles of long non-coding RNAs (lncRNAs), a class of long non-protein-coding RNAs, in the tumorigenesis of ovarian epithelial cells remain unknown. In this study, we discovered that the expression of long intergenic non-coding RNA 1088 (LINC01088) was clearly reduced in benign epithelial ovarian tumor tissues compared to matched normal ovarian tissues. This was shown by global cDNA gene chip scanning and real-time qPCR, and validated in 42 clinical specimens. Furthermore, we found that LINC01088 inhibited the growth of ovarian cancer xenografts in nude mice...

Osteosarcoma (OS) is the most common type of primary malignant bone tumor and mainly occurs in children and adolescent. Because of its early migration and invasion, OS has a poor prognosis. It has been reported that mircoRNAs (miRNAs) play a crucial role in the occurrence and development of multiple tumors. In this study, we identified the aberrant-expression of miR-143-3p in osteosarcoma and examined the role of miR-143-3p in OS development. Further, we searched the miR-143-3p target gene and verified its accuracy by luciferase experiments...

Binge drinking is commonly associated with high risk of cardiovascular diseases although the underlying mechanism remains elusive. Advances in genomics and genetics have indicated a number of alcohol-responsive genes in alcohol drinking behavior and alcoholic organ injury. Recent findings revealed a dramatic rise in mircoRNA-10a (miR-10a) and miR-21 levels with binge drinking (Beech et al., 2014). Given the increased knowledge in the past decade on the role of non-coding RNAs in the regulation of cardiovascular function, the identification of novel microRNA and underlying cellular mechanisms in alcoholism and alcoholic organ complication suggests therapeutic promises for the interventions against alcoholic complications...

Emerging studies have focused on the essential role of long non‑coding RNAs (lncRNAs) in cervical carcinogenesis. A recent study has indicated that nuclear paraspeckle assembly transcript 1 (NEAT1) is highly expressed in the human cervical tissue. However, whether NEAT1 is involved in cervical cancer remains to be elucidated. Reverse transcription‑quantitative polymerase chain reaction results demonstrated that the expression of NEAT1 was higher in cervical cancer cells/tissues compared with that in normal human keratinocytes/tissues...

Hyperglycemia-induced stress in the brain of patients with diabetes triggers the disruption of blood-brain barrier (BBB), leading to diverse neurological diseases including stroke and dementia. Recently, the role of microRNA becomes an interest in the research for deciphering the mechanism of brain endothelial cell damage under hyperglycemia. Therefore, we investigated whether mircoRNA Let7A (miR-Let7A) controls the damage of brain endothelial (bEnd.3) cells against high glucose condition. Cell viability, cell death marker expressions (p-53, Bax, and cleaved poly ADP-ribose polymerase), the loss of tight junction proteins (ZO-1 and claudin-5), proinflammatory response (interleukin-6, tumor necrosis factor-α), inducible nitric oxide synthase, and nitrite production were confirmed using MTT, reverse transcription-PCR, quantitative-PCR, Western blotting, immunofluorescence, and Griess reagent assay...

Krüppel-like Factor 4 (KLF4), a target gene of miR-145, can negatively regulate lung fibrosis. However, the potential role of KLF4 and miR-145 in hepatic stellate cells (HSCs) activation or in hepatic fibrosis keeps unclear. This study aims to characterize miR-145 and KLF4 in activated HSCs and liver cirrhotic, and the underlying molecular basis. miR-145 was significantly up-regulated, while KLF4 was dramatically down-regulated during the activation of rat primary HSCs and TGF-βtreated HSCs. Furthermore, miR-145 mimics induced and inhibition of miR-145 reduced α-SMA and COL-I expression in primary HSCs...

Diabetes initially induces distal axonal damage of peripheral nerves, but molecular mechanisms that mediate axonal injury are not fully understood. MircoRNAs (miRNAs) regulate axonal growth. We found that diabetic db/db mice exhibited substantial upregulation of miR-29c in dorsal root ganglia (DRG) neurons, sciatic nerve, and foot pad tissues. Bioinformatic analysis revealed PRKCI, a gene that encodes a member of the protein kinase C (PKC) iota, as a putative target for miR-29c. Western blot analysis showed that diabetic mice exhibited a considerable reduction of PRKCI protein levels in sciatic nerve tissues and DRG neurons...

Although previous studies suggested that microRNA-506-3p (miR-506-3p) was frequently downregulated, and functioned as a tumor suppressor in several cancers, the biological role and intrinsic regulatory mechanisms of miR-506-3p in non-small cell lung cancer (NSCLC) remain elusive. The present study found miR-506-3p expression was downregulated in advanced NSCLC tissues and cell lines. The expression of miR-506-3p in NSCLC was inversely correlated with larger tumor size, advanced TNM stage and lymph node metastasis...

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a progressive syndrome with a high incidence and mortality rate. Apoptosis is a very important pathological feature of ALI. Recently, more and more researches on mircoRNAs are involved in the regulation of proliferation and apoptosis of cancer cells. However, the functions of microRNAs in ALI remain unknown. In this study, PCR array and qRT-PCR were used to investigate microRNA profiles and miR-181a regulates apoptosis induced by LPS. Then, we predict the potential target gene of miR-181a is BCL-2 by bioinformatics methods, and validate it using luciferase reporter gene assays...

Invadopodia formation and extracellular matrix degradation are key events during cancer cell invasion, yet little is known about mechanisms mediating these processes. Here, we report that Rab40b plays a key role in mediating invadopodia function during breast cancer cell invasion. We also identify Tks5 (also known as SH3PXD2A), a known Src kinase substrate, as a new Rab40b effector protein and show that Tks5 functions as a tether that mediates Rab40b-dependent targeting of transport vesicles containing MMP2 and MMP9 to the extending invadopodia...

Although increasing evidence demonstrated that deregulation of mircoRNA-503 (miRNA-503) contributes to tumorigenesis, little is known about the biological role and intrinsic regulatory mechanisms of miR-503 in prostate cancer (PCa). In present study, we found that miR-503 was significantly downregulated in advanced PCa tissues and cell lines. Downregulation of miR-503 was strongly associated with aggressive clinical-pathological features and poor prognosis in PCa patients. Ectopic expression of miR-503 significantly inhibited tumor cells growth, cell migration and invasion in vitro and in vivo...
