Calcineurin/NFAT Signaling Modulates Pulmonary Artery Smooth Muscle Cell Proliferation, Migration and Apoptosis in Monocrotaline-Induced Pulmonary Arterial Hypertension Rats.
Pulmonary arterial hypertension (PAH) is a severe and debilitating disease characterized by remodeling of the pulmonary vessels, which is driven by excessive proliferation and migration and apoptosis resistance in pulmonary artery smooth muscle cells (PASMCs). The calcineurin (CaN)/nuclear factor of activated T-cells (NFAT) signaling pathway is the most important downstream signaling pathway of store-operated Ca2+ entry (SOCE), which is increased in PAH. CaN/NFAT has been reported to contribute to abnormal proliferation in chronic hypoxia (CH)-induced PAH. However, the effect of CaN/NFAT signaling on PASMC proliferation, migration and apoptosis in monocrotaline (MCT)-induced PAH remains unclear. ⋯ Our results demonstrate that CaN/NFAT signaling is activated and involved in the modulation of PASMC proliferation, migration and apoptosis in MCT-induced PAH.

lncRNA TUG1-Mediated Mir-142-3p Downregulation Contributes to Metastasis and the Epithelial-to-Mesenchymal Transition of Hepatocellular Carcinoma by Targeting ZEB1.
MicroRNA-142-3p (miR-142-3p) is dysregulated in many malignancies and may function as a tumor suppressor or oncogene in tumorigenesis and tumor development. However, few studies have investigated the clinical significance and biological function of miR-142-3p in hepatocellular carcinoma (HCC). ⋯ The results of this study suggest that the TUG1/miR-142-3p/ ZEB1 axis contributes to the formation of malignant behaviors in HCC.

Propofol Alters Long Non-Coding RNA Profiles in the Neonatal Mouse Hippocampus: Implication of Novel Mechanisms in Anesthetic-Induced Developmental Neurotoxicity.
Propofol induces acute neurotoxicity (e.g., neuroapoptosis) followed by impairment of long-term memory and learning in animals. However, underlying mechanisms remain largely unknown. Long non-coding RNAs (lncRNAs) are found to participate in various pathological processes. We hypothesized that lncRNA profile and the associated signaling pathways were altered, and these changes might be related to the neurotoxicity observed in the neonatal mouse hippocampus following propofol exposure. ⋯ This novel report emphasizes that propofol alters profiles of lncRNAs, mRNAs, and their cooperative signaling network, which provides novel insights into molecular mechanisms of anesthetic-induced developmental neurodegeneration and preventive targets against the neurotoxicity.

Ganoderic Acid A Protects Rat H9c2 Cardiomyocytes from Hypoxia-Induced Injury via Up-Regulating miR-182-5p.
Ganoderic acid A (GAA) isolated from Ganoderma lucidum, shows various benefit activities, such as anti-tumor activity, anti-HIV activity and hepatoprotective activity. However, the potential effects of GAA on hypoxia-induced injury of cardiomyocytes are still unclear. In this study, we aimed to reveal the effects of GAA on hypoxic-induced H9c2 cell injury, as well as potential underlying molecular mechanisms. ⋯ GAA protected rat H9c2 cardiomyocytes from hypoxia-induced injury might via up-regulating miR-182-5p, down-regulating PTEN and then activating PI3K/AKT signaling pathway.

Berberine Exerts a Protective Effect on Gut-Vascular Barrier via the Modulation of the Wnt/Beta-Catenin Signaling Pathway During Sepsis.
The gut-vascular barrier (GVB) has recently been depicted to dampen the bacterial invasion of the bloodstream. The intestinal mucosa is a tissue rich in small vessels including capillaries. In this study, the protective effect of berberine on GVB in small bowel mucosa was investigated. ⋯ Berberine exerted a protective effect on GVB function in sepsis, which was strictly related to the modulation of the Wnt/beta-catenin signaling pathway.
