Downregulation of long noncoding RNA H19 rescues hippocampal neurons from apoptosis and oxidative stress by inhibiting IGF2 methylation in mice with streptozotocin-induced diabetes mellitus.

The diabetes mellitus (DM)-induced reduction of neurogenesis in the hippocampus is consequently accompanied by cognitive decline. The present study set out to define the critical role played by long noncoding RNA H19 (lncRNA H19) in the apoptosis of hippocampal neurons, as well as oxidative stress (OS) in streptozotocin (STZ)-induced DM mice through regulation of insulin-like growth factor 2 (IGF2) methylation. The expression of lncRNA H19 in the hippocampal neurons and surviving neurons were detected. Hipp...

Imaging of Community-acquired Pneumonia.

Community-acquired pneumonia refers to an acute infection of the lung in patients who did not meet any of the criteria for health care-acquired pneumonia, and is associated with at least some symptoms of acute infection, accompanied by the presence of an acute infiltrate on a chest radiograph. Chest radiography remains an important component of the evaluation of a patient with a suspicion of pneumonia, and is usually the first examination to be obtained. The diagnosis of community-acquired pneumonia is base...

Impact of Dysphagia Assessment and Management on Risk of Stroke-Associated Pneumonia: A Systematic Review.

microRNA-668 represses MTP18 to preserve mitochondrial dynamics in ischemic acute kidney injury.

The pathogenesis of ischemic diseases remains unclear. Here we demonstrate the induction of microRNA-668 (mir-668) in ischemic acute kidney injury (AKI) in human patients, mice, and renal tubular cells. The induction was HIF-1dependant as HIF-1-deficiency in cells and kidney proximal tubules attenuated mir-668 expression. We further identified a functional HIF-1 binding site in mir-668 gene promoter. Anti-mir-668 increased apoptosis in renal tubular cells and enhanced ischemic AKI in mice, whereas mir-668 m...

miR-122 removal in the liver activates imprinted microRNAs and enables more effective microRNA-mediated gene repression.

miR-122 is a highly expressed liver microRNA that is activated perinatally and aids in regulating cholesterol metabolism and promoting terminal differentiation of hepatocytes. Disrupting expression of miR-122 can re-activate embryo-expressed adult-silenced genes, ultimately leading to the development of hepatocellular carcinoma (HCC). Here we interrogate the liver transcriptome at various time points after genomic excision of miR-122 to determine the cellular consequences leading to oncogenesis. Loss of miR...

MicroRNA-34a targets sirtuin 1 and leads to diabetes-induced testicular apoptotic cell death.

Testicular apoptotic cell death (TACD) contributes to diabetes mellitus (DM)-induced male infertility. MicroRNA-34a (miR-34a) is a pro-apoptotic RNA that targets sirtuin 1 (SIRT1) which provides protection against complications of (DM). However, the specific role of miR-34a in (DM)-induced TACD is unknown. MiR-34a targets Sirt1 mRNA, resulting in apoptosis. However, whether or not SIRT1 is a major target of miR-34a in (DM)-induced TACD is unclear. The present study aimed to define the role of miR-34a/SIRT1...

Costunolide ameliorates lipoteichoic acid-induced acute lung injury via attenuating MAPK signaling pathway.

Lipoteichoic acid (LTA)-induced acute lung injury (ALI) is an experimental model for mimicking Gram-positive bacteria-induced pneumonia that is a refractory disease with lack of effective medicines. Here, we reported that costunolide, a sesquiterpene lactone, ameliorated LTA-induced ALI. Costunolide treatment reduced LTA-induced neutrophil lung infiltration, cytokine and chemokine production (TNF-α, IL-6 and KC), and pulmonary edema. In response to LTA challenge, treatment with costunolide resulted less iN...

Imbalanced Expression of IGF2 and PCSK4 is Associated with Overproduction of Big IGF2 in SFT with NICTH: A Pilot Study.

Non-islet cell tumor hypoglycemia (NICTH) is a rare but serious paraneoplastic syndrome associated with large tumors. The high molecular weight insulin-like growth factor (IGF) 2, known as "big" IGF2, is produced by culprit tumors and leads to severe hypoglycemia. The detailed mechanism of its production in NICTH, however, remains unclear.

MicroRNA-9 modified bone marrow-derived mesenchymal stem cells (BMSCs) repair severe acute pancreatitis (SAP) via inducing angiogenesis in rats.

Severe acute pancreatitis (SAP) is an acute abdominal disease characterized by pancreatic necrosis and systemic disease. In a previous study, we showed that bone marrow-derived mesenchymal stem cells (BMSCs) can reduce SAP by secreting microRNA (miR)-9; however, the underlying mechanism remains unclear. The present study investigated the mechanism underlying BMSC-induced pancreatic regeneration.

MicroRNA-146a protects against LPS-induced organ damage by inhibiting Notch1 in macrophage.

MicroRNA-146a is a well-studied microRNA participating in immune and inflammatory diseases, but its role in sepsis has not been investigated. Here in our study, we found increased level of microRNA-146a in macrophage stimulated by lipopolysaccharide. In addition, the mRNA level of Notch1 was also increased. Up-regulation of microRNA-146a by miR-146a-mimic alleviated inflammatory responses of macrophage, for the levels of IL-1β, IL-6 and CCL-2 were decreased, and the activation of NF-κB signaling was inhib...

Disruption of the Igf2 gene alters hepatic lipid homeostasis and gene expression in the newborn mouse.

Newborns with intrauterine growth-restriction are at increased risk of mortality and life-long co-morbidities. Insulin-like growth factor-II (IGF2) deficiency in humans as well as in mice leads to intrauterine growth restriction and decreased neonatal glycogen stores. The present study aims to further characterize the metabolic and transcriptional consequences of Igf2 deficiency in the newborn. We found that, despite being born significantly smaller than their wild-type (Igf2) littermates, brain size was pr...

Our aim was to determine the association of several common H19-IGF2 variants and IRF in a cohort of elderly healthy individuals. The study involved 675 individuals >65 years of age, 184 with type 2 diabetes mellitus (T2DM), and 105 with IRF (estimated glomerular filtration rate [eGFR]

MicroRNA-126 attenuates cell apoptosis by targeting TRAF7 in acute myeloid leukemia cells.

Acute myeloid leukemia (AML) has only about 30%-40% five years survival rate due to the leukemia stem-like cells (LSCs) with self-renewal and differentiation ability. To address the novel therapeutic targets in LSCs, we investigated the roles of miRNA-126 and TRAF7 in AML.

Potential Role of Gr-1+ CD8+ T Lymphocytes as a Source of Interferon-γ and M1/M2 Polarization during the Acute Phase of Murine Legionella pneumophila Pneumonia.

In this study, we analyzed interferon (IFN)-γ-producing cells and M1/M2 macrophage polarization in Legionella pneumophila pneumonia following anti-Gr-1 antibody treatment. Anti-Gr-1 treatment induced an M1-to-M2 shift of macrophage subtypes in the lungs and weakly in the peripheral blood, which was associated with increased mortality in legionella-infected mice. CD8+ T lymphocytes and natural killer cells were the dominant sources of IFN-γ in the acute phase, and anti-Gr-1 treatment reduced the number of ...

Molecular mechanism of Notch signaling with special emphasis on microRNAs: Implications for glioma.

Glioma is the most aggressive primary brain tumor and is notorious for resistance to chemoradiotherapy. Although its associated mechanisms are still not completely understood, Notch signaling, an evolutionarily conserved pathway, appears to be the key processes involved. Nevertheless, its mechanisms are sophisticated, due to a variety of targets and signal pathways, especially microRNA. MicroRNAs, which are small noncoding regulatory RNA molecules, have been proposed as one of the key mechanisms in glioma p...

Inhibition of SIRT1 by microRNA-9, the key point in process of LPS-induced severe inflammation.

Severe inflammation may lead to multiple organs dysfunction syndrome, which has a high mortality. MicroRNA is found participated in this process. In this study we developed a lipopolysaccharide-induced inflammation cell model on macrophages and a lipopolysaccharide-induced inflammation mouse model. It was found that during inflammation, microRNA-9 was increased, accompanied with the up-regulation of pro-inflammatory cytokines and anti-inflammatory cytokines. Down-regulation of microRNA-9 inhibited the up-re...

Estrogen receptor-beta is a potential target for triple negative breast cancer treatment.

Triple Negative breast cancer (TNBC) is a subtype of breast cancer that lacks the expression of estrogen receptor (ER), progesterone receptor, and human epidermal growth factor receptor 2. TNBC accounts for 15-20% of all breast cancer cases but accounts for over 50% of mortality. We propose that Estrogen receptor-beta (ERβ) and IGF2 play a significant role in the pathogenesis of TNBCs, and could be important targets for future therapy. Tissue microarrays (TMAs) from over 250 TNBC patients' were analyzed fo...
