Abstract
Recently, long non-coding RNAs (lncRNAs) are considered as critical regulators in pathogenesis progression of cerebral ischemia. In present study, lncRNA-small nucleolar RNA host gene 14 (SNHG14) was found upregulated in middle cerebral artery occlusion/reperfusion (MCAO/R) treated brain tissues and oxygen-glucose deprivation and reoxygenation (OGD/R) treated PC-12 cells. Interference of SNHG14 by shRNA vector enhanced neuron survival and suppressed inflammation in response to OGD/R insult. SNHG14 positively regulated the expression of Rho-associated coiled-coil-containing protein kinase 1 (ROCK1) via acting as a sponge of microRNA (miR)-136–5p. SNHG14 promoted neurological impairment and inflammatory response through elevating the expression of ROCK1 while decreasing miR-136–5p level in OGD/R induced damage. Collectively, we illustrated that SNHG14 could be a novel strategy for treatment ischemia stoke.

Yes-associated protein (Yap), a regulator of cellular apoptosis, has been demonstrated to be involved in cerebral ischemia–reperfusion (IR) injury through poorly defined mechanisms. The present study aimed to explore the role of Yap in regulating cerebral IR injury in vitro, with a focus on mitochondrial fission and ROCK1/F-actin pathways. Our data demonstrated that Yap was actually downregulated in N2a cells after cerebral hypoxia-reoxygenation (HR) injury, and that lower expression of Yap was ...

Abstract Sulfasalazine (SF) promotes remyelination and improves the outcome of multiple sclerosis (MS) patients. However, the underlining mechanism remains elusive. Here, we examined whether SF blocks microglia switching to a pro-inflammatory M1-like phenotype through a competing endogenous RNA (ceRNA) effects in cuprizone-induced demyelination. The microglia reprogramming effects of SF in the mice model of cuprizone-induced demyelination was measured by histological, immunohistochemical and mol...

Notch signaling plays an emerging role in the regulation of immune cell development and function during inflammatory response. Activation of the ras homolog gene family, member A (RhoA)/Rho-associated protein kinase (ROCK) pathway promotes leukocyte accumulation in tissue injury. However, it remains unknown whether Notch signaling regulates RhoA/ROCK-mediated immune responses in liver ischemia and reperfusion injury (IRI). This study investigated intracellular signaling pathways regulated by Not...

Stroke is one of the leading causes of mortality and disability worldwide. Uncovering the cellular and molecular pathophysiological processes in stroke have been a top priority. Long non-coding (lnc) RNAs play critical roles in different kinds of diseases. In recent years, a bulk of aberrantly expressed lncRNAs have been screened out in ischemic stroke patients or ischemia insulted animals using new technologies such as RNA-seq, deep sequencing, and microarrays. Nine specific lncRNAs, antisense ...

Abstract Renal ischemia-reperfusion injury (IRI) is a leading cause of acute kidney injury (AKI) resulting in an abrupt deterioration of kidney function. CXC chemokine ligand 16 (CXCL16) contributes significantly to the pathogenesis of renal injury. However, the signaling pathway mechanisms of CXCL16 in IRI-induced AKI remains obscured. In this study, we examined the role of the CXCL16/ Rho Associated Coiled-Coil Containing Protein Kinase-1 (ROCK1) signaling pathway in AKI induced by IRI. In viv...

Abstract Background Spinal cord ischemia is a serious injury that threatens human health and life. Furthermore, it was widely accepted that miR-136 was mediated in the spinal injury, while whether it regulated neurocytes apoptosis in I/R-induced spinal cord injury remains unclear. Methods Spinal cord ischemia injury (SCII) rats were induced by clamping the nontraumatic vascular clip on the abdominal aorta. Real-time PCR was conducted to determine the mRNA expression, and western blot was carried...

Abstract Activated microglia cells (MCs) are able to release a large amount of inflammatory cytokines after ischemic stroke, which exacerbates neuron damage. In this study, we explored the functional involvement of long non-coding RNA (lncRNA) SNHG14 and its potential regulatory mechanism in the activation of MCs. The mouse model of middle cerebral artery occlusion (MCAO) and microglia cell model of oxygen/glucose deprivation (OGD) were made. The expression of SNHG14, miR-145-5p and PLA2G4A prot...

Here, we aimed to investigate the effects of lncRNA LOC366613 (LOC366613) on cerebral I/R injury, as well as its possible mechanism. Transient middle cerebral artery occlusion (MCAO) was used to establish a mouse model of cerebral I/R, and the PC12 cell line was used to establish an in vitro oxygen-glucose deprivation (OGD) injury model.

Cerebral ischemia-reperfusion (CI/R) injury is a serious central nervous system disease. Propofol (PPF) exerts a neuroprotective effect in CI/R injury; the underlying cause is still unclear. Here, we cultured mouse hippocampal neuron (HT22 cells) in oxygen-glucose deprivation/reoxygenation (OGD/R) conditions to mimic CI/R injury in vitro. PPF treatment promoted cell viability and reduced apoptotic cells in the OGD/R-treated HT22 cells, which was effectively abrogated by SNHG14 overexpression. Mo...

Acute kidney injury (AKI) is a complex syndrome with an abrupt decrease of kidney function, which is associated with high morbidity and mortality. Sepsis is the common cause of AKI. Mounting evidence has demonstrated that long non-coding RNAs (lncRNAs) play critical roles in the development and progression of sepsis-induced AKI. In this study, we aimed to illustrate the function and mechanism of lncRNA SNHG14 in lipopolysaccharide (LPS)-induced AKI. We found that SNHG14 was highly expressed in t...

Cerebral ischaemia/reperfusion (I/R) injury-induced irreversible brain injury is a major cause of mortality and functional impairment in ageing people. Gastrodin (GAS), derived from the traditional Chinese herbal medicine Tianma, has been reported to inhibit the progression of stroke, but the mechanism whereby GAS modulates the progression of cerebral I/R remains unclear. The middle cerebral artery occlusion method was used as a model of I/R in vivo. Rats were pretreated with GAS by intraperiton...

Abstract Osteoarthritis (OA) is the joint pain and dysfunction syndrome caused by severe joint degeneration. The overproduced inflammatory mediators contribute greatly to OA development. It is reported that long non-coding RNA (lncRNA) takes part in many inflammatory diseases. Here, we mainly explored the function of lncRNA SNHG14 in OA process and its specific mechanisms. An OA rat model was induced by destabilizing the medial meniscus (DMM) and IL-1β (5 ng/ml) was used to mediate an OA cell mo...
