Genomic Study of RNA Polymerase II and III SNAPc-Bound Promoters Reveals a Gene Transcribed by Both Enzymes and a Broad Use of Common Activators

David Paul Roger Romascano, Nouria Hernandez

SNAP(c) is one of a few basal transcription factors used by both RNA polymerase (pol) II and pol III. To define the set of active SNAP(c)-dependent promoters in human cells, we have localized genome-wide four SNAP(c) subunits, GTF2B (TFIIB), BRF2, pol II, ...

Nanopore sensing is a single-molecule technique that allows to probe the nano-bio-world with accuracy. It is a non-invasive technique, which means that the molecule of interest does not need to be labeled to be detected by the nanopore. Most of the studies ...

Genomics and transcriptomics of the Mycobacterium tuberculosis complex

Swapna Uplekar

The goal of eliminating tuberculosis (TB) by 2050 depends on the development of improved TB diagnostics, drugs and vaccines. Advances in these areas require a deep understanding of the disease and its causative agent, Mycobacterium tuberculosis (M. tb). My ...

Widespread occurrence of non-canonical transcription termination by human RNA polymerase III

Human RNA polymerase (Pol) III-transcribed genes are thought to share a simple termination signal constituted by four or more consecutive thymidine residues in the coding DNA strand, just downstream of the RNA 3'-end sequence. We found that a large set of ...

In Vivo Studies on the Control of Gene Expression and Protein Degradation

Karolina Bojkowska

Cellular homeostasis is maintained by tightly regulated gene networks, controlled notably at the levels of transcription, mRNA processing, and protein post-translational modification and turnover. This thesis focuses on two of these regulatory steps, namel ...

The Interplay between Cytidine Deaminases, HIV and Domesticated Genetic Parasites

"There is more virus in us than us in us". John Coffin's famous sentence illustrates that particular nucleic acid sequences related to exogenous viruses, called retrotransposons, constitute almost half of the human genome and largely exceeds the amount of ...

Chromatin remodeling through histone posttranslational modifications (PTMs) and DNA methylation has recently been implicated in cognitive functions, but the mechanisms involved in such epigenetic regulation remain poorly understood. Here, we show that prot ...

The human SPT20-containing SAGA complex plays a direct role in the regulation of endoplasmic reticulum stress-induced genes

One of the central questions in eukaryotic transcription is how activators can transmit their signal to stimulate gene expression in the context of chromatin. The multisubunit SAGA coactivator complex has both histone acetyltransferase and deubiquitination ...

The Myc trilogy: lord of RNA polymerases

Cancer cells have a raised cellular metabolism, including increased protein biosynthesis. Three new studies now show that the oncoprotein Myc, known to drive cell division, also enhances ribosomal RNA synthesis by RNA polymerase I in addition to controllin ...

Since the advent of microarrays, vast amounts of gene expression data have been generated. However, these microarray data fail to reveal the transcription regulatory mechanisms that underlie differential gene expression, because the identity of the respons ...
