Computational Prediction of Intronic microRNA Targets using Host Gene Expression Reveals Novel Regulatory Mechanisms

Approximately half of known human miRNAs are located in the introns of protein coding genes. Some of these intronic miRNAs are only expressed when their host gene is and, as such, their steady state expression levels are highly correlated with those of the host gene's mRNA. Recently host gene expression levels have been used to predict the targets of intronic miRNAs by identifying other mRNAs that they have consistent negative correlation with. This is a potentially powerful approach because it allows a large number of expression profiling studies to be used but needs refinement because mRNAs can be targeted by multiple miRNAs and not all intronic miRNAs are co-expressed with their host genes

Functional crosstalk between histone H2B ubiquitylation and H2A modifications and variants

Ubiquitylation of H2B is associated with transcription and regulation of chromatin structure. Here, the authors perform an unbiased screen to identify the role of chromatin modifications on ubiquitylation of H2BK120 and characterize the crosstalk between H2BK120ub and H2A modifications and variants
