Long non-coding RNAs (ncRNA) have recently been demonstrated to be expressed from a subset of enhancers and to be required for the distant regulation of gene expression. Several approaches to predict enhancers have been developed based on various chromatin marks and occupancy of enhancer-binding proteins. Despite the rapid advances in the field, no consensus how to define tissue specific enhanc...

Enhancers are short regulatory sequences bound by sequence-specific transcription factors and play a major role in the spatiotemporal specificity of gene expression patterns in development and disease. While it is now possible to identify enhancer regions genomewide in both cultured cells and primary tissues using epigenomic approaches, it has been more challenging to develop methods to underst...

Enhancers are cis-acting DNA elements that play critical roles in distal regulation of gene expression. Identifying enhancers is an important step for understanding distinct gene expression programs that may reflect normal and pathogenic cellular conditions. Experimental identification of enhancers is constrained by the set of conditions used in the experiment. This requires multiple experiment...

Enhancers are short DNA regulatory elements which play a vital role in gene expression. Due to their important roles genomics, several computational models have been proposed the literature for identification of enhancers and strengths using traditional machine learning algorithms, however, unable identify strength with reasonable accuracy because high non-linearity sequences. This article prop...

conclusions the most effective enhancer for aha and ha were liquid paraffin and glycerol, respectively. the most effective surfactant for both aha and ha was tween 80. the effects of the enhancers were increased by prolonging the exposure time. results after 1.5 and 12 hours, the maximum permeated amount of aha were 89.8 and 342.5 mg, respectively, which related to the formulations with liquid ...

An increasing number of healthy adolescents are consuming products that can enhance their cognitive performance in educational settings. Currently, the use of pharmaceuticals is the most widely discussed enhancement method in the literature, but new evidence suggests that other methods based on Transcranial Electrical Stimulation (tES) also have potential as cognitive enhancer. Just like pharma...

the aim of the present study was to investigate the influence and the mechanisms of cineoleand terpineol on the in-vitro transdermal delivery of huperzine a from microemulsions, andtheir potential synergistic effect on the permeation enhancement. the transdermal deliveryof huperzine a from microemulsions with different concentrations of cineole and terpineolthrough the rat abdominal skin was de...

many properties of chemicals depend on their stereochemistry. among these, the effects of stereoisomerism on percutaneous absorption of drugs are not well studied. we have previously shown that permeation of tretinoin and isotretinoin (two geometric isomers) through hydrophilic enhancers-treated rat skin is stereoselective. as, depending on their lipophilicity, penetration enhancers can change ...

In higher eukaryotes, transcriptional enhancers play critical roles in the integration of cellular signaling information, but apart from a few well-studied model enhancers, we lack a general picture of transcriptional information processing by most enhancers. Here we discuss recent studies that have provided fresh insights on information processing that occurs on enhancers, and propose that in ...
