BACKGROUND: This study aimed at exploring the effect of microRNA-129-5p (miR-129-5p) targeting high mobility group box-1 (HMGB1)-receptor for advanced glycation end-products (RAGE) signaling pathway on the revascularization in a collagenase-induced intracerebral hemorrhage (ICH) rat model. METHODS: OX26-pGFAP-IL, an immunoliposome expressing miR-129-5p was constructed. The collagenase-induced ICH rat models were successfully established by 96 Sprague Dawley (SD) rats, which were categorized into the sham group, ICH group, miR-129-5p group, negative control (NC) group, ethyl pyruvate (EP, an inhibitor of HMGB1) group and N-benzyl-4-chloro-N-cyclohe-xylbenzamide (FPS-ZM1, a RAGE receptor antagonist) group...

UCP2 maps nearby the lod score peak of STR1-stroke QTL in the SHRSP rat strain. We explored the potential contribution of UCP2 to the high-salt diet (JD)-dependent increased stroke susceptibility of SHRSP. Male SHRSP, SHRSR, two reciprocal SHRSR/SHRSP-STR1/QTL stroke congenic lines received JD for 4 weeks to detect brain UCP2 gene/protein modulation as compared with regular diet (RD). Brains were also analyzed for NF-κB protein expression, oxidative stress level and UCP2-targeted microRNAs expression level...

Microglia seed the embryonic neuro-epithelium, expand and actively sculpt neuronal circuits in the developing central nervous system, but eventually adopt relative quiescence and ramified morphology in the adult. Here, we probed the impact of post-transcriptional control by microRNAs (miRNAs) on microglial performance during development and adulthood by generating mice lacking microglial Dicer expression at these distinct stages. Conditional Dicer ablation in adult microglia revealed that miRNAs were required to limit microglial responses to challenge...

Erythropoietin (EPO) is an erythropoiesis stimulating growth factor and hormone. EPO has been widely used in the treatment of chronic renal failure, cancer, and chemotherapy-related anemia for three decades. However, many clinical trials showed that EPO treatment may be associated with tumorigenesis and cancer progression. EPO is able to cross blood-brain barriers, and this may lead to an increased possibility of central nervous system tumors such as glioblastoma. Indeed, EPO promotes glioblastoma growth and invasion in animal studies...

BACKGROUND: Brain metastasis (BM) is associated with poor prognosis in patients with non-small cell lung cancer (NSCLC). Recent studies demonstrated that microRNA-330-3p (miR-330-3p) was involved in NSCLC brain metastasis (BM). However, the exact parts played by miR-330-3p in BM of NSCLC remain unknown. Discovery and development of biomarkers and elucidation of the mechanism underlying BM in NSCLC is critical for effective prophylactic interventions. Here, we evaluated the expression and biological effects of miR-330-3p in NSCLC cells and explored the underlying mechanism of miR-330-3p in promoting cell migration and invasion in NSCLC...

Hypoxic-ischemic brain injury (HIBI) results in death or long-term neurologic impairment in both adults and children. In this study, we investigated the effects of microRNA-132 (miR-132) dysregulation on oxygen-glucose deprivation (OGD)-induced apoptosis in fetal rat hippocampal neurons, in order to reveal the therapeutic potential of miR-132 on HIBI. MiR-132 dysregulation was induced prior to OGD exposure by transfection of primary fetal rat hippocampal neurons with miR-132 mimic or miR-132 inhibitor. The effects of miR-132 overexpression and suppression on OGD-stimulated hippocampal neurons were evaluated by detection of cell viability, apoptotic cells rate, and the expression of apoptosis-related proteins...

Glioma is the most common form of primary malignant tumor that occurs in the central nervous system. The underlying molecular mechanism of the carcinogenesis and progression of glioma remains to be elucidated. It is well‑established that microRNAs (miRs) are associated with the regulation of glioma initiation and progression, and may represent a novel effective therapeutic strategy for the treatment of glioma. In the present study, the expression, roles and molecular mechanisms of miR‑205 in glioma were investigated...

Gliomas are the most common primary central nervous system tumors and account for approximately 80% of malignant brain tumors. MicroRNAs (miRNAs) are a class of small non-coding, regulatory RNA molecules that mediate the expression levels of specific proteins. As a member of the miRNA family, miR-543 plays a tumor suppressive or an oncogenic role in different types of tumors. However, the expression and role of miR-543 in glioma remain unknown. In the present study, the expression level of miR-543 in glioma cell lines and tissues was investigated...

The intrinsic ability of neurogenesis after stroke has been proven weak, which results in insufficient repair of injury in the nerve system. Recent studies suggest multiple microRNAs (miRNAs) are involved in the neuroremodeling process. Targeted miRNAs delivery for amplification of neurogenesis is promising in promoting the prognosis after ischemia. Here, we showed that modified exosomes, with rabies virus glycoprotein (RVG) fused to exosomal protein lysosome-associated membrane glycoprotein 2b (Lamp2b), could efficiently deliver miR-124 to the infarct site...

Glioma accounts for the majority of primary malignant brain tumors in adults and is highly aggressive. Although various therapeutic approaches have been applied, outcomes of glioma treatment remain poor. MicroRNAs are a class of small noncoding RNAs that function as regulators of gene expression. Accumulating evidence shows that microRNAs are associated with tumorigenesis and tumor progression. In this study, we found that miR-105 is significantly downregulated in glioma tissues and glioma cell lines. We identified suppressor of Zeste 12 homolog as a novel direct target of miR-105 and showed that suppressor of Zeste 12 homolog protein levels were inversely correlated with the levels of miR-105 expression in clinical specimens...

MicroRNAs are small non-coding RNAs that modulate gene expression post-transcriptionally. Discovered more than 15 years ago, their functions start to be unraveled. Increasing evidence points to an important functional role of microRNAs in brain development. In particular, miRNAs have recently been established to play a vital role in the mechanisms underlying the infantile rise in gonadotropin-releasing hormone (GnRH) production by neurons in the hypothalamus, a phenomenon necessary for the onset of puberty in mammals...

There is a need for diagnostic biomarkers of epilepsy and status epilepticus to support clinical examination, electroencephalography and neuroimaging. Extracellular microRNAs may be potentially ideal biomarkers since some are expressed uniquely within specific brain regions and cell types. Cerebrospinal fluid offers a source of microRNA biomarkers with the advantage of being in close contact with the target tissue and sites of pathology. Here we profiled microRNA levels in cerebrospinal fluid from patients with temporal lobe epilepsy or status epilepticus, and compared findings to matched controls...

Several lines of evidence indicate that microRNAs (miRNAs) modulate tolerance to the analgesic effects of morphine via regulation of pain-related genes, making dysregulation of miRNA levels a clinical target for controlling opioid tolerance. However, the precise mechanisms by which miRNAs regulate opioid tolerance are unclear. In the present study, we noted that the miR-375 level was downregulated but the expression of Janus kinase 2 (JAK2) was upregulated in mouse dorsal root ganglia (DRG) following chronic morphine treatment...

ETHNOPHARMACOLOGICAL RELEVANCE: The discovery of many tissue-specific cancer stem cells (CSCs) continues to attract scientific attention. These CSCs are considered to be associated with chemo- and radio-resistance, and consequently, failure of conventional anticancer therapies. The recent demonstration of several microRNAs as enhancers of tumorigenicity via modulation of epithelial-mesenchymal transition and cancer stemness, makes them putative novel therapeutic target in oncology. Antrodia cinnamomea is a Chinese traditional medicine with several biological functions including anti-inflammation, antioxidant, and cancer prevention...

MicroRNAs are small non-coding RNAs that play crucial roles in the regulation of gene expression and protein synthesis during brain development. MiR-3099 is highly expressed throughout embryogenesis, especially in the developing central nervous system. Moreover, miR-3099 is also expressed at a higher level in differentiating neurons in vitro, suggesting that it is a potential regulator during neuronal cell development. This study aimed to predict the target genes of miR-3099 via in-silico analysis using four independent prediction algorithms (miRDB, miRanda, TargetScan, and DIANA-micro-T-CDS) with emphasis on target genes related to brain development and function...

Trans-resveratrol (tRESV), a polyphenol with antioxidant properties, is common in many food sources, hence easily accessible for study as a maternal dietary supplement in perinatal asphyxia (PA). Hypoxic-ischemic encephalopathy secondary to PA affects especially vulnerable brain areas such as hippocampus and is a leading cause of neonatal morbidity. The purpose of this study is to identify new epigenetic mechanisms of brain inflammation and injury related to PA and to explore the benefit of tRESV enriched maternal diet...
