Abstract:
The adenovirus E1A gene is known to be autoregulated at the level of transcription. Autoregulation was found to be mediated by products of the E1A 13S mRNA, which induced a fivefold increase in E1A transcription rate. Deletion analysis suggested that the autoregulation did not require any specific sequence in the E1A transcriptional control region. This conclusion was reinforced by the demonstration that a cellular alpha-globin gene substituted for the E1A gene on the adenovirus chromosome was also positively regulated by E1A gene products.

Abstract:
HNF-4α (hepatocyte nuclear factor-4α) is required for tissue-specific expression of many of the hepatic, pancreatic, enteric and renal traits. Heterozygous HNF-4α mutants are inflicted by MODY-1 (maturity onset diabetes of the young type-1). HNF-4α expression is reported here to be negatively autoregulated by HNF-4α1 and to be activated by dominant-negative HNF-4α1. Deletion and chromatin immunoprecipitation analysis indicated that negative autoregulation by HNF-4α1 was mediated by its association with the TATA-less HNF-4α core promoter enriched in Sp1, but lacking DR-1 response elements.

Abstract:
Simultaneous resistance to an array of drugs with different cytotoxic activities is a property of Saccharomyces cerevisiae, in which the protein Pdr3p has recently been shown to play a role as a transcriptional regulator. We provide evidence that the yeast PDR3 gene, which encodes a zinc finger transcription factor implicated in certain drug resistance phenomena, is under positive autoregulation by Pdr3p. DNase I footprinting analyses using bacterially expressed Pdr3p showed specific recognition by this protein of at least two upstream activating sequences in the PDR3 promoter. The use of lacZ

Abstract:
The Drosophila homeotic gene Ultrabithorax (Ubx) encodes transcriptional regulatory proteins (UBX) that specify thoracic and abdominal segmental identities. Ubx autoregulation was examined by manipulating UBX levels, both genetically and with an inducible transgene, and monitoring the effect of these manipulations on the expression of Ubx and Ubx-lacZ reporter genes. Positive autoregulation by Ubx is restricted to the visceral mesoderm, while in other tissues Ubx negatively autoregulates. In some cases, negative autoregulation stabilizes UBX levels, while in others it modulates the spatial and

Abstract:
Transcriptional repression of E-cadherin, characteristic of epithelial to mesenchymal transition, is often found also during tumor cell invasion. At metastases, migratory fibroblasts sometimes revert to an epithelial phenotype, by a process involving regulation of the E-cadherin–β-catenin complex. We investigated the molecular basis of this regulation, using human colon cancer cells with aberrantly activated β-catenin signaling. Sparse cultures mimicked invasive tumor cells, displaying low levels of E-cadherin due to transcriptional repression of E-cadherin by Slug. Slug was induced by β-caten

Abstract:
Plant embryogenesis is an intriguing developmental process that is controlled by many genes. AGAMOUS Like 15 (AGL15) is a MADS-domain transcriptional regulator that accumulates preferentially during this stage. However, at the onset of this work it was unknown which genes are regulated by AGL15 or how AGL15 is regulated. This dissertation is part of the ongoing effort to understand the biological roles of AGL15. To decipher how AGL15 functions during plant development, a chromatin immunoprecipitation (ChIP) approach was adapted to obtain DNA fragments that are directly bound by AGL15 in vivo.

Le virus d’Epstein-Barr (EBV) est un herpèsvirus humain qui infecte 90% de la population, mais l’infection est, le plus souvent, asymptomatique. Après infection, le virus établit une latence virale caractérisée par l’expression restreinte de gènes viraux, appelés gènes de latence permettant au virus de persister tout au long de la vie. On définit trois latences virales (I, II et III) selon le profil d’expression des gènes de latence codant les antigènes EBNAs (-1, -2, -3 et -LP) et les protéines membranaires LMPs (-1 et -2).

The methods that fueled the microscale revolution (top-down design/fabrication, combined with application of forces large enough to overpower stochasticity) constitute an approach that will not scale down to nanoscale systems. In contrast, in nanotechnology, we strive to embrace nature’s quite different paradigms to create functional systems, such as self-assembly to create structures, exploiting stochasticity, rather than overwhelming it, in order to create deterministic, yet highly adaptable, behavior.

Deep Mutational Scanning (DMS) approaches help elucidate sequence-function-phenotype relationships in proteins, which ultimately improves our understanding of residue (or nucleotide)-specific contributions to protein function and organismal fitness. Such comprehensive knowledge finds use in reliable prediction of consequences of mutations, as well as in protein design and engineering. We have investigated the molecular mechanisms of how mutations at surface exposed sites, away from the active sites in a model protein, CcdB produce drastic defects on the protein’s activity and organismal phenot

We built and simulated the regulatory interactions that determine organ specificity using an extension of hybrid Petri nets as implemented in Cell Illustrator.
