Inflammation plays an essential role in vascular pathologies, including those associated with sepsis and atherosclerosis. Identifying negative regulators of inflammatory signaling pathways may provide novel therapeutic targets for these diseases. In this issue of the JCI, Sun et al. show that in endothelial cells, microRNA-18 1b (miR-18 1b) plays a vital role in controlling inflammation by targ...

P27Kip1, also known as Cyclin-dependent kinase inhibitor 1B, is an important check-point protein in the cell cycle. It has been identified that although as a tumor suppressor, P27Kip1 is expressed in different cancer cell types, which shows the therapeutic potential in tumor genesis. In this study, we examined the upstream regulatory mechanism of P27Kip1 at the microRNA (miRNA) level in gastric...

Hepatocellular carcinoma (HCC) is the leading cause of cancer related death worldwide. The number of deaths is proportional to the global incidence, which highlights the aggressive tumor biology and lack of effective therapies. Dysregulation of microRNAs has been implicated in carcinogenesis and progression of liver cancer. Here, we identified that miR-1258 was significantly downregulated in HC...

MicroRNAs (miRNAs) are known to play a part in regulating important cellular processes. They generally perform their regulatory function through their binding with mRNAs, ultimately leading to a repression of target protein expression levels. However, their roles in cellular processes are poorly understood due to the limited understanding of their specific cellular targets. Aberrant levels of m...

Hematopoiesis depends on a tightly controlled balance of selfrenewal, proliferation, cell death and differentiation. Although the disturbance of this equilibrium creates a predisposition to leukemogenesis, targeted manipulation or modulation can in turn lead to therapeutic advances. In addition to chromosomal aberrations and frequently mutated genes such as NPM1 and FLT3, dysregulation of micro...

abstract        background and objective: various cellular factors affect the process of hiv activity. one of these cellular factors are structures known as microrn that are expected to be involved in controlling hiv replication and infectivity. the expression of one or a set of them may represent the patient's clinical conditions. in this study,  the expression of mir-29a and mir-29b invo...

Abstract Introduction Vasoplegic syndrome (VS) is one of the most common unexpected complications following cardiothoracic surgery, approaching a 25% mortality rate. No standardized methods for diagnosing VS are available. A biomarker valuable tool in all fields medicine, especially cardiovascular disease when patient has to undergo invasive surgery as on-pump CABG. MicroRNAs (miRNAs) have been...

The HJ-1B satellite, which was launched on September 6, 2008, is one of the small ones placed in the constellation for disaster prediction and monitoring. HJ-1B imagery was simulated in this paper, which contains fires of various sizes and temperatures in a wide range of terrestrial biomes and climates, including RED, NIR, MIR and TIR channels. Based on the MODIS version 4 contextual algorithm ...

Hematopoietic-specific miR-142 is a critical regulator of various blood cell lineages including CD4 dendritic cells and platelet biogenesis in megakaryocytes. Furthermore, we recently reported that miR-142 is required in order to maintain the biconcave shape of erythrocytes, their structural resilience and lifespan, through a mechanism that involves actin filament homeostasis. Here, we used a m...
