BACKGROUND Cardiac hypertrophy and subsequent heart failure triggered by chronic hypertension represent major challenges for cardiovascular research. Beyond neurohormonal and myocyte signaling pathways, growing evidence suggests inflammatory signaling pathways as therapeutically targetable contributors to this process. We recently reported that microRNA-155 is a key mediator of cardiac inflamma...
OBJECTIVE This study was to screen for the miRNAs differently expressed in peripheral blood mononuclear cells (PBMC) of RA, to further identify the expression of miR-155 in RA PBMC and fibroblast-like synoviocytes (FLS), and to evaluate the function of miR-155 in RA-FLS. METHODS Microarray was used to screen for differentially expressed miRNAs in RA PBMC. miR-155 expression in PBMC and FLS of...
Cancer has been a major public health issue all over the world and cancer patients diagnosed at early stages have a comparatively favorable prognosis. The association between specific dysregulated expressed microRNA-155 (miRNA-155, miR-155) and tumorigenesis has been identified by numerous studies. However, perplexity and inconsistence arise from a wide range of studies due to heterogeneity. Th...
BACKGROUND A low dose injection of lipopolysaccharides (LPS) may induce pre-eclampsia-like symptoms in rats, and microRNA-155 (miR-155) is elevated in the placentas of patients with pre-eclampsia. Our goal was to investigate the association of miR-155 with pre-eclampsia and the pathways involved using human-trophoblast-derived cell line (HTR-8/SVneo) stimulated with LPS. METHODS We measured m...
OBJECTIVE Epstein-Barr virus (EBV)-encoded latent membrane protein (LMP1) can drive aberrant expression of miR-155 in nasopharyngeal carcinoma (NPC). In this study, we investigated the regulation of miR-155 expression over UBQLN1 and studied their effects on radio-sensitivity of NPC. MATERIALS AND METHODS MiR-155, LMP1 and ubiquilin-1 expression were measured in 40 cases of NPC cases. The reg...
We first investigated the difference in microRNA expression between normal NP cells and degenerative NP cells using gene chip. We have found that the expression of ERK1/2 was decreased with overexpression of miR-155 in normal nucleus pulposus cell. Expression of ERK1/2 was increased with inhibition of miR-155. Overexpression or inhibition of miR-155 had no effects on the expression level of mRN...
Accumulating evidence shows that mircroRNAs (miRNAs) play a vital role in tumorigenesis. miR-155 is one of the most multifunctional miRNAs whose overexpression has been found to be associated with different types of cancer including breast cancer. To further determine the potential involvement of miR-155 in breast cancer, we evaluated the expression levels of miR-155 by real-time PCR and correl...
MicroRNA is small non-coding RNA and can lead to translational repression or target degradation by base-pairing with complementary sequences of mRNA molecules. MicroRNA-155 (miR-155), one of the most studied microRNA, is the first one to be reported as oncogenic [1]. miR-155 is over expressed in a long list of both hematological and solid tumors and is of paramount importance in cancer diagnosi...
MicroRNAs (miRNAs) are a recently discovered class of small non-coding RNAs that regulate gene expression. miRNAs can contribute to cancer development and progression and are differentially expressed in normal tissue and cancer. In the present study, our aim was to investigate the expression of miR-155 in gastric cancer and to explore the mechanisms by which it influences gastric cancer cells. ...
The Drosophila kinesin-family protein Costal 2 (Cos2) and its mammalian ortholog Kif7 play dual roles in Hedgehog (Hh) signaling. In theabsenceofHh,Cos2andKif7 contribute toproteolytic processing and silencing of the Hh-regulated transcription factors, Drosophila Cubitus interruptus (Ci) andmammalianGli proteins. Cos2 andKif7 are also necessary for full activation of full-length Ci-155 and Gli ...
