OBJECTIVE: The aim of the present work was to study the prevention of liver cancer angiogenesis via miR-126. For this purpose, experimentations were conducted. MATERIALS AND METHODS: The precursor sequence of miR-126 was amplified in the DNA of human liver cancer cell lines. We, therefore, constructed the overexpression and interference vectors of miR-126 in vitro; which were respectively transferred to liver cancer cells in the logarithmic phase and inoculated under both sides of the back skin of Balb/c-nu nude mice aged 4-6 weeks with 10 mu l (1 x 105) cell suspension...

OBJECTIVE: Janus kinase (JAK)- signal transducer and activator of transcription (STAT) signaling pathway participates in regulating cell proliferation, differentiation, and apoptosis, and related to lymphoma. Suppressors of cytokine signaling 3 (SOCS3) is a negative regulator of the JAK-STAT signaling pathway. SOCS3 reduction and miR-155 up-regulation are associated with lymphoma pathogenesis. Bioinformatics analysis showed the complementary binding site between miR-155 and SOCS3. This study aimed to investigate the role of miR-155 in regulating SOCS3/JAK-STAT signaling pathway and affecting diffuse large B cell lymphoma (DLBCL) cell proliferation and apoptosis...

OBJECTIVE: Glycogen Synthase Kinase-3β (GSK-3β) negatively regulates Wnt/β-catenin signaling pathway through degrading β-catenin protein. It plays an inhibitory role in various tumors, while the influence in the pathogenesis of renal carcinoma has not been elucidated. MicroRNA-155 (MiR-155) was found to be upregulated in renal carcinoma tissue. Bioinformatics analysis revealed the complementary binding site between miR-155 and 3'-UTR of GSK-3β. This study investigated the influence of miR-155 in regulating GSK-3β expression, Wnt/β-catenin signaling pathway activity, and renal carcinoma cell proliferation, invasion, and apoptosis...

Cognitive impairments are a prevalent and disabling non-motor complication of Parkinson's disease, but with variable expression and progression. The onset of serious cognitive decline occurs alongside substantial cholinergic denervation, but imprecision of previously available techniques for in vivo measurement of cholinergic degeneration limit their use as predictive cognitive biomarkers. However, recent developments in stereotactic mapping of the cholinergic basal forebrain have been found useful for predicting cognitive decline in prodromal stages of Alzheimer's disease...

Ovarian folliculogenesis is always of great interest in reproductive biology. However, the molecular mechanisms that control follicle development, particularly the early phase of follicle activation or recruitment, still remain poorly understood. In an attempt to decipher the gene networks and signaling pathways involved in such transition, we conducted a transcriptomic analysis (RNA-seq) on zebrafish primary growth (PG, stage I; inactive) and pre-vitellogenic (PV, stage II; activated) follicles. A total of 118 unique microRNAs (miRNAs) (11 down-regulated and 83 up-regulated during PG/PV transition) and 56711 unique messenger RNAs (mRNAs) (1839 down-regulated and 7243 up-regulated during PG/PV transition) were identified...

Thrombospondin-1 (THBS1) is an important mediator of corpus luteum (CL) regression. Highly induced during luteolysis, it acts as a natural anti-angiogenic, proapoptotic compound. THBS1 expression is regulated in bovine luteal endothelial cells (LECs) by fibroblast growth factor-2 (FGF2) and transforming growth factor-beta1 (TGFB1) acting in an opposite manner. In this study we sought to identify specific microRNAs (miRNAs) targeting THBS1 and investigate their possible involvement in FGF2 and TGFB1-mediated THBS1 expression...

BACKGROUND Poor transplant outcome was observed in donation after brain death followed by circulatory death (DBCD), since the donor organs suffered both cytokine storm of brain death and warm ischemia injury. MicroRNAs (miRNAs) have emerged as promising disease biomarkers, so we sought to establish a miRNA signature of porcine DBCD and verify the findings in human liver transplantation. MATERIAL AND METHODS MiRNA expression was determined with miRNA sequencing in 3 types of the porcine model of organ donation, including donation after brain death (DBD) group, donation after circulatory death (DCD) group, and DBCD group...

This study aimed to explore the role of MALAT1 in sepsis-induced cardiac inflammation and dysfunction. We constructed the rat sepsis models through cecal ligation and puncture (CLP). The cardiac function, including left ventricular peak pressure (LVPP), left ventricular end diastolic pressure (LVEDP) and maximum rate of rise/fall of left ventricle pressure (±dp/dtmax) as well as the contents of serum cardiac troponin I (CTn-I), creatine kinase (CK), and creative kinase isoenzyme MB (CK-MB) were detected after modeling...

AIMS: Esophageal squamous cell carcinoma (ESCC) is characterized by high prevalence and mortality worldwide, and it is very highly prevalent in China. ESCC is caused by various factors, including microRNAs (miRNAs) whose expression have been shown to play a major role in tumor generation. Single nucleotide polymorphisms (SNPs) in miRNAs could affect susceptibility to numerous cancers. This study aimed to evaluate the relationship between SNPs in miR-124 and ESCC risk in the Chinese Kazakh population...

This study investigates the protective effects of miR-431 against cerebral ischemia-reperfusion injury through the Rho/Rho-kinase signaling pathway. SD rats were randomly classified into normal, sham and model (middle cerebral artery occluded) groups. Rho expression and cerebral infarction were visualized by immunohischemistry and TTC staining, respectively. qRT-PCR and western blotting were used to measure mRNA and protein expression of miR-431 and Rho/Rho-kinase signaling pathway-related genes. Hippocampal neurons were extracted and assigned into normal, blank, negative control (NC), miR-431 mimics, miR-431 inhibitors, siRNA-Rho and miR-431 inhibitors + siRNA-Rho groups...

Gastric cancer ranks as the second leading cause of malignancy-related death worldwide, and always diagnosed at advanced stage. MicroRNA-222-3p (miR-222-3p) is aberrantly upregulated in various malignant tumors including gastric cancer, but its role and underlying molecular mechanisms in gastric cancer remain largely unknown. Helicobacter pylori (H. pylori) infection acts as a trigger in the development of gastric cancer, and increasing evidence suggests that H. pylori affects microRNA expression. In this study, gastric cancer tissue samples were divided into H...

Increasing evidence highlights the important role of XIST, a long non-coding RNA (lncRNA), in the regulation of multiple cancers. However, the underlying mechanism of XIST in human hepatocellular carcinoma (HCC) still remains to be explored. Herein, intended to investigate the functional role of XIST in HCC initiation and progression. We first detected that XIST was significantly upregulated in HCC tissues and associated with tumor size and vascular invasion. Gain- and loss-of-function of XIST further presented that XIST promoted the progression of HCC cells, including proliferation, migration, and invasion...

Long non-coding RNAs (lncRNAs) are emerging as important players in regulation of gene expression in higher eukaryotes. DDX5/p68 RNA helicase protein which is involved in splicing of precursor mRNAs also interacts with lncRNAs like, SRA and mrhl, to modulate gene expression. We performed RIP-seq analysis in HEK293T cells to identify the complete repertoire of DDX5/p68 interacting transcripts including 73 single exonic (SE) lncRNAs. The LOC284454 lncRNA is the second top hit of the list of SE lncRNAs which we have characterized in detail for its molecular features and cellular functions...
