The role of microRNAs in adipocyte differentiation

null

《医学前沿（英文）》 2013年第7卷第2期页码 223-230 doi: 10.1007/s11684-013-0252-8

摘要：

Adipocytes differentiate from mesenchymal stem cells (MSCs) in a process known as adipogenesis. The programme of adipogenesis is regulated by the sequential activation of transcription factors and several signaling pathways. There is growing evidence indicating that a class of small non-coding single-stranded RNAs known as “microRNAs (miRNAs)” also are involved in this process. In this review, we summarize the biology and functional mechanisms of miRNAs in adipocyte differentiation. In addition, we further discuss the miRNAs profiling, the miRNAs function and miRNAs target prediction in the adipogenesis.

摘要： Cold stress is an environmental factor affecting plant development and production. Recently, microRNAs (miRNAs) have been found to be involved in several plant processes such as growth regulation and stress responses. Although miRNAs and their targets have been identified in several banana species, their participation during cold accumulation in banana remains unknown. In this study, two small RNA libraries were generated from micropropagated plantlets of grown at normal and low temperature (5°C). A total of 69 known miRNAs and 32 putative novel miRNAs were detected in the libraries by Solexa sequencing. Sixty-four cold-inducible miRNAs were identified through differentially expressed miRNAs analysis. Among 43 miRNAs belonging to 26 conserved miRNA families with altered expression, 18 were upregulated and 25 downregulated under cold stress. Of 21 putative novel miRNAs with altered expression, four were downregulated and 17 upregulated. Furthermore, eight miRNAs were validated by stem-loop qRT-PCR and their dynamic differential expression was analyzed. In addition, 393 target genes of 58 identified cold-responsive miRNAs were predicted and categorized by function. These results provide important information for further characterization and functional analysis of cold-responsive miRNAs in banana.

Circulating microRNAs in cardiovascular diseases: from biomarkers to therapeutic targets

null

《医学前沿（英文）》 2014年第8卷第4期页码 404-418 doi: 10.1007/s11684-014-0379-2

摘要：

microRNAs (miRNAs) are a class of conserved, short, non-coding RNAs that have important and potent capacities to regulate gene expression at the posttranscriptional level. In the past several years, the aberrant expressions of miRNAs in the cardiovascular system have been widely reported, and the crucial roles of some special miRNAs in heart development and pathophysiology of various cardiovascular diseases have been gradually recognized. Recently, it was discovered that miRNAs are presented in peripheral circulation abundantly and stably. This has raised the possibility of using circulating miRNAs as biomarkers for diseases. Furthermore, some studies demonstrated that circulating miRNAs may serve as novel extracellular communicators of cell-cell communication. These discoveries not only reveal the functions of circulating miRNAs in cardiovascular system but also inform the development of miRNAs therapeutic strategies. In this review, we discuss the potential roles of circulating miRNAs in a variety of cardiovascular diseases from biomarkers to therapeutic targets to clearly understand the roles of circulating miRNAs in cardiovascular system.

MicroRNAs and lung cancers: from pathogenesis to clinical implications

null

《医学前沿（英文）》 2012年第6卷第2期页码 134-155 doi: 10.1007/s11684-012-0188-4

摘要：

Lung cancer is the leading cause of cancer-related deaths in the US and worldwide. Better understanding of the disease is warranted for improvement in clinical management. Here we summarize the functions of small-RNA-based, posttranscriptional gene regulators, i.e. microRNAs, in the pathogenesis of lung cancers. We discuss the microRNAs that play oncogenic as well as tumor suppressive roles. We also touch on the value of microRNAs as markers for diagnosis, prognosis and the promising field of microRNA-based novel therapies for lung cancers.

MicroRNAs and their roles in osteoclast differentiation

Zhuying Xia, Chao Chen, Peng Chen, Hui Xie, Xianghang Luo

《医学前沿（英文）》 2011年第5卷第4期页码 414-419 doi: 10.1007/s11684-011-0168-0

摘要： Osteoclasts, which are derived from monocyte-macrophage precursors, are exclusive bone resorption cells. Limited evidence indicates that a class of small non-coding single-stranded RNAs known as “microRNAs” (miRNAs) is also involved in bone resorption. Although various miRNAs regulate cell proliferation and differentiation, few miRNAs have been reported to play a key role in the regulation of osteoclast differentiation. In this short review, the biology and functional mechanisms of miRNAs in osteoclastogenesis are summarized. The profiling, function, and target prediction of miRNAs are discussed as well.

MicroRNAs and hepatitis viruses

《医学前沿（英文）》 2009年第3卷第3期页码 265-270 doi: 10.1007/s11684-009-0055-0

摘要： MicroRNAs (miRNAs) are a class of small RNA molecules. They play a pivotal role in diverse domains such as infection, tumorigenesis, and immune reaction. As key regulators of most genes’ expression, they react at posttranscriptional level. It is increasingly clear that miRNAs are necessary for physiological and pathological processes. In the past few years, investigators gradually brought the concept of miRNA into studies of viral infection, including hepatitis viruses. The hepatitis B and C viruses are common causes of liver disease worldwide. It is very difficult to cure chronic hepatitis due to drug resistance during antivirus therapy. Elucidating the mechanisms of virus-host interactions in hepatitis B and C is very important in diagnosis, prognosis, and therapy. This article reviews the current knowledge of viral hepatitis (B and C type) at the level of miRNA and tries to outline areas of potential studies.

Loss of monocarboxylate transporter 1 aggravates white matter injury after experimental subarachnoid hemorrhage in rats

《医学前沿（英文）》 2021年第15卷第6期页码 887-902 doi: 10.1007/s11684-021-0879-9

摘要： Monocarboxylic acid transporter 1 (MCT1) maintains axonal function by transferring lactic acid from oligodendrocytes to axons. Subarachnoid hemorrhage (SAH) induces white matter injury, but the involvement of MCT1 is unclear. In this study, the SAH model of adult male Sprague-Dawley rats was used to explore the role of MCT1 in white matter injury after SAH. At 48 h after SAH, oligodendrocyte MCT1 was significantly reduced, and the exogenous overexpression of MCT1 significantly improved white matter integrity and long-term cognitive function. Motor training after SAH significantly increased the number of ITPR2⁺SOX10⁺ oligodendrocytes and upregulated the level of MCT1, which was positively correlated with the behavioral ability of rats. In addition, miR-29b and miR-124 levels were significantly increased in SAH rats compared with non-SAH rats. Further intervention experiments showed that miR-29b and miR-124 could negatively regulate the level of MCT1. This study confirmed that the loss of MCT1 may be one of the mechanisms of white matter damage after SAH and may be caused by the negative regulation of miR-29b and miR-124. MCT1 may be involved in the neurological improvement of rehabilitation training after SAH.
