Gene Expression: Dialing Up the Frequency
Cells often respond to external signals by altering their gene expression. The external signaling information is transduced and typically encoded in concentrations of relevant transcription factors. A recent study demonstrates that, by encoding this information in the frequency with which genes 'see' a transcription factor, the expression of hundreds of genes can be modulated in a linearly prop...
متن کاملGene Expression: Sizing It All Up
Genomic architecture appears to be a largely unexplored component of gene expression. That architecture can be related to chromatin domains, transposable element neighborhoods, epigenetic modifications of the genome, and more. Although surely not the end of the story, we are learning that when it comes to gene expression, size is also important. We have been surprised to find that certain patte...
متن کاملNeuronal activity up-regulates astroglial gene expression.
Neuronal gene expression is known to be modulated by functional activity. This modulation is thought to play a key role in determining the differentiation of developing neurons and regulating the operation of mature neurons. Here we describe a regulation of astroglial gene expression by neuronal activity. We report that intense neuronal activity (electrically induced seizures) in rat hippocampu...
متن کاملBias from excluding Households without Telephones in Random Digit Dialing Surveys: Follow Up
I. INTRODUCTION The purpose of this paper is to investigate potential bias resulting from undercoverage of RDD sampling frames. Our method is to compare estimates of a variety of characteristics for households sampled by Random Digit Dialing (RDD) methods and those contacted in person as part of an area probability sample. A large number of surveys are conducted using RDD samples, and are restr...
متن کاملExtremely low frequency-pulsed electromagnetic fields affect proangiogenic-related gene expression in retinal pigment epithelial cells
Objective(s): It is known that extremely low frequency-pulsed electromagnetic fields (ELF-PEMF) influence multiple cellular and molecular processes. Retinal pigment epithelial (RPE) cells have a significant part in the emergence and pathophysiology of several ocular disorders, such as neovascularization. This study assessed the impact of ELF-PEMF on the proangiogenic features of RPE cells. Mate...
