ABSTRACT Background: This study aims to identify genes with a high likelihood of genetic variation, significant expression differences, and prognostic implications in colorectal cancer (CRC) patients. The research also seeks to investigate the role and mechanisms of key genes in CRC through the analysis of health information data and a combination of ...

RNA polymerase II stalling promotes nucleosome occlusion and pTEFb recruitment to drive immortalization by Epstein-Barr virus [PDF]
Epstein-Barr virus (EBV) immortalizes resting B-cells and is a key etiologic agent in the development of numerous cancers. The essential EBV-encoded protein EBNA 2 activates the viral C promoter (Cp) producing a message of ~120 kb that is differentially ...

Abstract Recombinant adeno‐associated virus (rAAV) is a widely used delivery vehicle in gene therapy. A scalable production technology is essential for its wide clinical applications. We have taken a synthetic biology approach to generate HEK293‐based cell lines which harbor integrated genetic elements encoding essential AAV and adenoviral helper ...

Distinct modes of regulation by chromatin encoded through nucleosome positioning signals.
The detailed positions of nucleosomes profoundly impact gene regulation and are partly encoded by the genomic DNA sequence. However, less is known about the functional consequences of this encoding.

How does the chromatin fiber deal with topological constraints?
In the nuclei of eukaryotic cells, DNA is packaged through several levels of compaction in an orderly retrievable way that enables the correct regulation of gene expression. The functional dynamics of this assembly involves the unwinding of the so-called

Beyond Histones: Unveiling the Functional Roles of Protein Acetylation in Prokaryotes and Eukaryotes
ABSTRACT Lysine acetylation plays a crucial role in cellular processes and is found across various evolutionary organisms. Recent advancements in proteomic techniques revealed the presence of acetylation in thousands of non‐histone proteins. Here, we conducted extensive meta‐analysis of 48 acetylomes spanning diverse organisms, including archaea ...
