Cluster size determines internal structure of transcription factories in human cells
Massimiliano Semeraro, Giuseppe Negro, Giada Forte +4
Transcription is a fundamental cellular process, and the first step of gene expression. In human cells, it depends on the binding to chromatin of various proteins, including RNA po…

Modelling transcriptional silencing and its coupling to 3D genome organisation
Massimiliano Semeraro, Giuseppe Negro, Davide Marenduzzo +1
Timely up- or down-regulation of gene expression is crucial for cellular differentiation and function. While gene upregulation via transcriptional activators has been extensively i…

A unified-field theory of genome organization and gene regulation
Giuseppe Negro, Massimiliano Semeraro, Perter R Cook +1
Our aim is to predict how often genic and non-genic promoters fire within a cell. We first review a parsimonious pan-genomic model for genome organization and gene regulation, wher…
