Abstract
BACKGROUND The miR-208 gene is one of the microRNAs now under active studies, and has been found to play significant roles in an array of cardiovascular diseases. Nevertheless, until now, no studies have examined the relationship between the susceptibility to ischemic stroke (IS) and genetic variations in miR-208. This study explored the association between the miR-208 polymorphisms (rs178642, rs8022522, and rs12894524) and the risk of IS. METHODS A total of 205 cases of IS and 211 control subjects were included. The SNPscans genotyping test was employed to determine the genotypes of the three polymorphisms. RESULTS Significant correlation was observed between rs8022522 polymorphism and risk of IS on the basis of analyses of genotypes, models and alleles (GA vs. GG: adjusted OR = 2.159, 95% CI: 1.052-4.430, P = 0. 036; AA vs. GG: adjusted OR = 5.154, 95% CI: 1.123-23.660, P = 0.035; dominant model: adjusted OR = 1.746, 95% CI, 1.075-2.838, P = 0.025; G vs. A: adjusted OR = 2.451, 95% CI: 1.374-4.370, P = 0.002). CONCLUSIONS The rs8022522 polymorphism of the miR-208 gene is significantly associated with an elevated risk of ischemic stroke in Chinese.

Abstract
Long non-coding RNAs (lncRNAs) regulate gene expression and play a significant role in cancer progression. Previously, downregulation of lncRNA MEG3 was shown to associate with poor clinical outcomes in melanoma patients. The basis for this association has not been described and the aims of this study were to identify a role for lncRNA MEG3 in melanoma and to describe its regulatory mechanism of action. RT-qPCR was used to detect lncRNA MEG3 expression in melanoma cells and tissues. Luciferase reporter assays were used to identify lncRNA MEG3 downstream targets. Melanoma cells were transfected with various expression vectors and these transfected cells were assessed for; migration, colony formation, proliferation, in vivo tumorigenesis, and metastatic potential. Melanoma cell lines were found to be sensitive to lncRNA MEG3 expression levels and overexpression was found to inhibit melanoma cell proliferation and invasion, both in vitro and in vivo. Luciferase reporter assays identified miR-208 and SOX4 as downstream targets of lncRNA MEG3. Overexpression of miR-208 and silencing of SOX4 rescued invasion and proliferation by cells that overexpressed lncRNA MEG3. Moreover, lncRNA MEG3 inhibited cancer stem cell differentiation and suppressed melanoma progression and metastasis through inhibition of miR-208 by SOX4.

Abstract
Healthy, premenopausal women have the advantage of female-specific cardiovascular protection compared to age-matched healthy men. However, pathologies such as obesity and Type 2 diabetes mellitus (T2DM) cause losing of this female-specific cardiovascular protection in young, obese and diabetic females. Molecular mechanisms underlying this loss of female-specific cardiovascular protection in young, obese and diabetic females are not clearly elucidated. This review takes a close look at the latest advances in our understanding of sex differences in adult cardiac gene expression patterns in health and disease. Based on the emerging data, this review proposes that female biased gene expression patterns in healthy adult hearts of human and pre-clinical models support the existence of active fetal gene program in healthy, premenopausal female heart compared to age-matched healthy male heart. However, the misalignment of gene expression pattern in this female-specific active cardiac fetal gene program caused by pathologies such as obesity and T2DM may contribute to the loss of female-specific cardiovascular protection in young, obese and diabetic females.

Abstract
This article aimed to investigate the role of miR-208 in the apoptosis of myocardial tissues in acute myocardial infarction (AMI) mice. The AMI mouse model was constructed. Then, miR-208 expression in AMI mice was regulated by transfection. The mouse myocardial tissues were subject to hematoxylin-eosin (HE) staining, TUNEL assay, and immunofluorescence analysis. H9c2 cell transfection and hypoxia induction were then completed, and cell apoptosis and cytokine levels were tested. Additionally, RNA pull-down and dual luciferase reporter gene assays were conducted for exploring the relation of miR-208 with programmed cell death 4 (PDCD4). Additionally, fluorescence in situ hybridization (FISH) was conducted for investigating miR-208 and PDCD4 colocalization within H9c2 cells. AMI mice had severe damage, apoptosis, decreased miR-208 expression, increased IL-1β, IL-6, IL-8 levels, whereas reduced IL-10 level within myocardial tissues. H9c2 cells under hypoxia induction exhibited decreased miR-208 expression, promoted apoptosis, increased protein expression of Bax and cleaved-caspase-3, decreased protein expression of Bcl-2 and caspase-3, elevated IL-1β, IL-6, IL-8 levels and decreased IL-10 level. miR-208 upregulation alleviated the damage and apoptosis of myocardial tissues in AMI mice. AMI mice with miR-208 upregulation showed decreased expression of Bax and cleaved-caspase-3, increased expression of Bcl-2 and caspase-3, reduced levels of IL-1β, IL-6, IL-8, whereas an increased level of IL-10. miR-208 showed direct inhibition of PDCD4. PDCD4 and miR-208 were mainly co-expressed in the cytoplasm. The upregulated PDCD4 expression abolished miR-208's suppression of H9c2 cell apoptosis induced by hypoxia. Besides this, miR-208 inhibited myocardial tissue apoptosis in AMI mice by inhibiting PDCD4 expression.

Abstract
MicroRNAs (miRNAs) are strongly up-regulated under pathological stress and in a wide range of diseases. In recent years, miRNAs are under investigation for their potential use as biomarkers in cardiovascular diseases. We investigate whether specific cardio-miRNAs are overexpressed in heart samples from subjects deceased for acute myocardial infarction (AMI) or sudden cardiac death (SCD), and whether miRNA could help differentiate between them. Forty four cases of death due to cardiovascular disease were selected, respectively, 19 cases categorized as AMI and 25 as SCD. Eighteen cases of traumatic death without pathological cardiac involvement were selected as control. Immunohistochemical investigation was performed for CD15, IL-15, Cx43, MCP-1, tryptase, troponin C and troponin I. Reverse transcription and quantitative real-time PCR were performed for miR-1, miR-133, miR-208 and miR-499. In AMI group, stronger immunoreaction for the CD15, IL-15 and MCP-1 antibodies was detectable compared with SCD and control. Cx43 showed a negative reaction with respect to the other groups. Real-time PCR results showed a down-regulation of all miRNAs in the AMI group compared with SCD and control. The selected miRNAs presented high accuracy in discriminating SCD from AMI (miR-1 and miR-499) and AMI from control (miR-208) representing a potential aid for both clinicians and pathologists for differential diagnosis.

Abstract
BACKGROUND Heart chamber-specific mRNA expression patterns have been extensively studied, and dynamic changes have been reported in many cardiovascular diseases. MicroRNAs (miRNAs) are also important regulators of normal cardiac development and functions that generally suppress gene expression at the posttranscriptional level. Recent focus has been placed on circulating miRNAs as potential biomarkers for cardiac disorders. However, miRNA expression levels in human normal hearts have not been thoroughly studied, and chamber-specific miRNA expression signatures in particular remain unclear. METHODS AND RESULTS We performed miRNA deep sequencing on human paired left atria (LA) and ventricles (LV) under normal physiologic conditions. Among 438 miRNAs, miR-1 was the most abundant in both chambers, representing 21% of the miRNAs in LA and 26% in LV. A total of 25 miRNAs were differentially expressed between LA and LV; 14 were upregulated in LA, and 11 were highly expressed in LV. Notably, the miR-208 family in particular showed prominent chamber specificity; miR-208a-3p and miR-208a-5p were abundant in LA, whereas miR-208b-3p and miR-208b-5p were preferentially expressed in LV. Subsequent real-time polymerase chain reaction analysis validated the predominant expression of miR-208a in LA and miR-208b in LV. CONCLUSIONS Human atrial and ventricular tissues display characteristic miRNA expression signatures under physiological conditions. Notably, miR-208a and miR-208b show significant chamber-specificity as do their host genes, α-MHC and β-MHC, which are mainly expressed in the atria and ventricles, respectively. These findings might also serve to enhance our understanding of cardiac miRNAs and various heart diseases.

Abstract
Prostate cancer (PC) is a prevalent cancer in aged men. Curcumin is an active ingredient that has been extracted from the rhizome of the plant Curcuma longa. Recently, a potential of Curcumin against PC has been reported in PC, whereas the underlying molecular mechanisms are not completely understood. Here, we studied the effects of low-dose Curcumin on PC cell growth. Curcumin (from 0.2 to 0.8 μmol/l) dose-dependently inhibited the proliferation of PC cells, without affecting cell apoptosis. Further analyses showed that Curcumin dose-dependently increased a cell cycle suppressor CDKN1A at protein levels, but not mRNA levels, in PC cells, suggesting that Curcumin may regulate the translation of CDKN1A, as well as a possible involvement of miRNA intervention. From all CDKN1A-3'-UTR-binding miRNAs, we found that miR-208 was specifically inhibited in PC cells dose-dependently by Curcumin. Moreover, miR-208 was found to bind CDKN1A to suppress its expression. In a loss-of-function experiment, PC cells that overexpressed miR-208 failed to decrease cell proliferation in response to Curcumin. Together, these data suggest that Curcumin inhibits growth of PC via miR-208-mediated CDKN1A activation.

Abstract
Several clinical observations have demonstrated a link between heart rate and anxiety or panic disorders. In these patients, β-adrenergic receptor function was altered. This prompted us to investigate whether the β-adrenergic receptor agonist isoproterenol, at a dose that stimulates peripheral β-adrenergic system but has no effects at the central nervous system, can induce anxiety-like behavior in rats. Moreover, some possible messengers involved in the peripheral to brain communication were investigated. Our results showed that isoproterenol (5 mg kg(-1) i.p.) increased heart rate, evoked anxiety-like behavior, did not result in motor impairments and increased extracellular vesicle content in the blood. Plasma corticosterone level was unmodified as well as vesicular Hsp70 content. Vesicular miR-208 was also unmodified indicating a source of increased extracellular vesicles different from cardiomyocytes. We can hypothesize that peripheral extracellular vesicles might contribute to the β-adrenergic receptor-evoked anxiety-like behavior, acting as peripheral signals in modulating the mental state.

Abstract
Cardiotoxicity is one of the major safety concerns in drug development. Therefore, detecting and monitoring cardiotoxicity throughout preclinical and clinical studies is important for pharmaceutical companies. The present study was conducted in order to explore a plasma miRNA biomarker for cardiotoxicity in rats. As organ specificity is an important factor for a biomarker, we analyzed the miRNA microarray dataset in 55 organs/tissues in normal male rats. Based on this analysis, 5 miRNAs consisting of miR-208 (heart-specific), miR-1, miR-133a, miR-133b (heart and skeletal muscle-specific) and miR-206 (skeletal muscle-specific) were selected. Next, we evaluated the usefulness of those 5 miRNAs as circulating biomarkers in rats administered with single-dose isoproterenol or doxorubicin. Plasma miR-208 was consistently increased through 24 h after dosing in rats administered with isoproterenol, whereas plasma concentrations of cardiac troponin (cTn) showed transient elevation. In contrast, the plasma levels of miR-1, miR-133a, miR-133a and miR-206 were elevated after treatment with doxorubicin, probably as a result of skeletal muscle toxicity. Additionally, the plasma miR-208 level was elevated even after repeat-dose administration (once daily for 7 days) of isoproterenol under which the pathological condition proceeded to the sub-chronic phase such as fibrosis. Thus, our data suggest that miR-208 is a promising plasma biomarker for cardiotoxicity in rats. Monitoring of plasma miR-208 levels in rats may lead to more accurate evaluation of cardiotoxicity in preclinical studies.
