Toll-like receptor 9 (TLR9) gene deletion-mediated fracture healing in type II diabetic osteoporosis associates with inhibition of the nuclear factor-kappa B (NF-κB) signaling pathway.

Diabetes is characterized by increased fracture risk. Evidence from studies is lacking for anti-fracture strategies in diabetes. Our microarray analyses predicted association of Toll-like receptor 9 (TLR9) with both diabetes and osteoporosis, which was the focus of this work in a murine model of type II diabetic osteoporosis (T2DOP).

SOC Estimation of Lithium-Ion Battery for Electric Vehicle Based on Deep Multilayer Perceptron.

The state of charge (SOC) is one of the main indexes of the lithium-ion battery, which affects the practice range of new energy vehicles and the safety of the battery. Nevertheless, the value of SOC cannot be measured directly. At present, the algorithm for estimating the state of charge is not very satisfactory.

MALAT1-mediated recruitment of the histone methyltransferase EZH2 to the microRNA-22 promoter leads to cardiomyocyte apoptosis in diabetic cardiomyopathy.

Diabetic patients often have a heightened risk of cardiomyopathy, even in the absence of traditional risk factors such as hypertension and atherosclerotic coronary artery disease. Diabetic cardiomyopathy is characterized by a typical cardiomyopathy specific to diabetes, the pathogenesis of which has yet to be fully elucidated. As a well-documented oncogenic long noncoding RNA (lncRNA), metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has been implicated in a variety of pathological processes, including diabetic complications.

Construction and Comprehensive Analysis of Dysregulated Long Noncoding RNA-Associated Competing Endogenous RNA Network in Moyamoya Disease.

Background: Moyamoya disease (MMD) is a rare cerebrovascular disease characterized by chronic progressive stenosis or occlusion of the bilateral internal carotid artery (ICA), the anterior cerebral artery (ACA), and the middle cerebral artery (MCA). MMD is secondary to the formation of an abnormal vascular network at the base of the skull. However, the etiology and pathogenesis of MMD remain poorly understood.

Linc-OIP5 in the breast cancer cells regulates angiogenesis of human umbilical vein endothelial cells through YAP1/Notch/NRP1 signaling circuit at a tumor microenvironment.

Background: LincRNAs have been revealed to be tightly associated with various tumorigeneses and cancer development, but the roles of specific lincRNA on tumor-related angiogenesis was hardly studied. Here, we aimed to investigate whether linc-OIP5 in breast cancer cells affects the angiogenesis of HUVECs and whether the linc-OIP5 regulations are involved in angiogenesis-related Notch and Hippo signaling pathways.

Methods: A trans-well system co-cultured HUVECs with linc-OIP5 knockdown breast cancer cell MDA-MB-231 was utilized to study the proliferation, migration and tube formation abilities of HUVECs and alterations of related signaling indicators in breast cancer cells and their conditioned medium through a series of cell and molecular experiments.

Overexpression of SDF-1 activates the NF-κB pathway to induce epithelial to mesenchymal transition and cancer stem cell-like phenotypes of breast cancer cells.

The formation of EMT and EMT-induced CSC-like phenotype is crucial for the metastasis of tumor cells. The stromal cell-derived factor-1 (SDF-1) is upregulated in various human carcinomas, which is closely associated with proliferation, migration, invasion and prognosis of malignancies. However, limited attention has been directed towards the effect of SDF-1 on epithelial to mesenchymal transition (EMT) or cancer stem cell (CSC)-like phenotype formation in breast cancer cells and the related mechanism.

HGF expression induced by HIF-1α promote the proliferation and tube formation of endothelial progenitor cells.

Hypoxia-inducible factor-1α (HIF-1α) and hepatocyte growth factor (HGF) play important roles in postnatal neovascularization. However, the interaction of these two pathways is not fully understood. The present study utilized CoCl(2) treated-endothelial progenitor cells (EPCs) (EPCs exposure to CoCl(2) are under mimic hypoxia) to examine the expressions of HIF-1α and HGF and futher to assess whether or not the inhibitor (2-methoxyestradiol [2ME2]) of HIF-1α decrease the HGF expression.

Synthetic liver X receptor agonist T0901317 attenuates high glucose-induced oxidative stress, mitochondrial damage and apoptosis in cardiomyocytes.

The aim of the present study was to investigate the protective effects of T0901317 (T0), a potent agonist of liver X receptors (LXRs), on high glucose-induced oxidative stress and apoptosis in H9c2 cardiac cells. Exposure of H9c2 cells to high glucose alone, not only caused a significant increase in apoptosis and reactive oxygen species (ROS) generation, but also led to a decrease in mitochondrial membrane potential (ΔΨm), release of cytochrome c, decrease in Bcl-2, increase in Bax expression and the activation of caspase-3, caspase-9, poly (ADP-ribose) polymerase (PARP) and nuclear factor (NF)-κB. However, pretreatment with T0 effectively decreased apoptosis, reduced the levels of ROS, abrogated ΔΨm, inhibited cytochrome c release and NF-κB activation, increased Bcl-2 and decreased Bax expression.
