Résumé :

ABSTRACT The elicitation of cellular antiviral activities is dependent on the rapid transcriptional activation of interferon (IFN) target genes. It is not clear how the interferon target promoters, which are organized into chromatin structures in cells, rapidly respond to interferon or viral stimulation. In this report, we show that alpha IFN (IFN-α) treatment of HeLa cells induced hundreds of genes. The induction of the majority of these genes was inhibited when one critical subunit of the chromatin-remodeling SWI/SNF-like BAF complexes, BAF47, was knocked down via RNA interference. Inhibition of BAF47 blocked the cellular response to viral infection and impaired cellular antiviral activity by inhibiting many IFN- and virus-inducible genes. We show that the BAF complex was required to mediate both the basal-level expression and the rapid induction of the antiviral genes. Further analyses indicated that the BAF complex primed some IFN target promoters by utilizing ATP-derived energy to maintain the chromatin in a constitutively open conformation, allowing faster and more potent induction after IFN-α treatment. We propose that constitutive binding of the BAF complex is an important mechanism for the IFN-inducible promoters to respond rapidly to IFN and virus stimulation.

Résumé :

149 Background: Chromatin remodeling factors have been the subject of great interest in oncology. However, little is known about their role in pancreatic cancer. The objective of this study is to clarify the clinical significance of SWI/SNF complex, one of the major chromatin remodeling machineries, in patients with pancreatic cancer. Methods: 68 cases with pancreatic cancer who underwent R0, 1 resection were enrolled. Cancer tissues were processed to tissue microarray, then stained immunohistochemically by using antibody of SWI/SNF components; BRM, BRG1, BAF250a, BAF180, and BAF47. The correlation of expression level and clinicopathological outcome including overall survival were analyzed. Results: Expression level of the SWI/SNF components was categorized as low or high according to the median value of Histo score. Statistical analysis revealed that related factors were tumor size, T factor, M factor, lymphatic invasion, and Stage in BRM, histology and Stage in BRG1, tumor size in BAF180, lymphatic invasion in BAF47, respectively. Multivariate Cox propotional hazard analysis showed high-BRM and low-BAF180 expression level were independent predictors of worse survival in patients with pancreatic cancer. The hazard analysis was also examined in the patients treated with adjuvant gemcitabine, indicating that high-BRM, and low-BAF180 were independent prognostic factors for poor survival. Conclusions: These results suggest that the specific cofactors of SWI/SNF chromatin remodeling complex certainly have roles in pancreatic cancer. High-BRM, and low-BAF180 are useful markers for prognosis of pancreatic cancer.

Résumé :

Abstract Atypical teratoid rhabdoid tumor (ATRT) is a rare, highly malignant central nervous system cancer arising in infants and younger children, historically considered to be homogeneous, monogenic, and incurable. Recent use of intensified therapies has modestly improved survival for ATRT; however, a majority of patients will still succumb to their disease. While ATRTs almost universally exhibit loss of SMARCB1 (BAF47/INI1/SNF5), recent whole genome, transcriptome, and epigenomic analyses of large cohorts reveal previously underappreciated molecular heterogeneity. These discoveries provide novel insights into how SMARCB1 loss drives oncogenesis and confer specific therapeutic vulnerabilities, raising exciting prospects for molecularly stratified treatment for patients with ATRT.

Résumé :

Context.—Medulloblastomas (MBs) and atypical teratoid/rhabdoid tumors (AT/RTs) arising in infants and children can be difficult to distinguish; however, histologic characterization is prognostically important. Objective.—To determine histologic and phenotypic markers associated with utility with progression-free survival (PFS) and overall survival (OS) in children younger than 3 years with MBs and AT/RTs. Design.—We undertook a histologic and immunophenotypic study of MBs and AT/RTs arising in infants and children younger than 3 years treated in a Pediatric Brain Tumor Consortium study. The 41 girls and 55 boys ranged in age from 2 to 36 months at enrollment. These infants and children exhibited 51 MBs, 26 AT/RTs, and 24 other tumors (not further studied). Median follow-up of the patients was 17.2 months from diagnosis (range: 1.4–93 months). Results.—Infants and children with AT/RT exhibited a statistically significant shorter PFS and OS when compared to infants and children with MBs (both P < .001). A lack of nuclear BAF47 immunohistochemical reactivity proved reliable in identifying AT/RTs. Among MBs, our data suggest an association of nodularity and prolonged PFS and OS, which must be independently confirmed. Anaplasia correlated with OTX2 reactivity and both OTX2 and moderate to severe anaplasia correlated with PFS but not with OS. Conclusion.—Distinguishing AT/RT from MBs is clinically important. For expert neuropathologists, the diagnoses of AT/RT and MB can be reliably made from hematoxylin-eosin stains in the vast majority of cases. However certain rare small cell variants of AT/RT can be confused with MB. We also found that immunohistochemical reactivity for BAF47 is clinically useful in distinguishing MBs from AT/RTs and for identifying certain small cell AT/RTs. Among MBs, nodularity may be an important prognostic factor for improved PFS and OS in infants and children.

Résumé :

La chromatine est une structure dynamique régulée par différents mécanismes épigénétiques parmi lesquels le remodelage de la chromatine dépendant de l’ATP comme le SWI/SNF. Leur importance est telle que les mutations des protéines de remodelage de la chromatine sont fortement associées à plusieurs maladies dont le cancer. Par exemple les protéines BCL7, qui sont de nouvelles sous unité centrales récemment identifié du complexe SWI/SNF des mammifère, sont associées à différents types de cancers comme dans le Diffuse Large B-cell Lymphoma (DLBCL). Les informations sur les protéines BCL7 sont à ce jour très limitées. En utilisant des approches biochimiques et structurelles, ce projet vise à mieux comprendre la structure et la fonction de ces sous unités auxiliaires. Nous rapportons ici que les protéines se lient à l’acidique patch du nucleosome avec sa regions N-terminal qui comprend un motif d’ancrage arginines et que la mutation de l’une de ces arginines impacte directement la liaison au nucleosome. Nous apportons aussi une hypothèse sur la position au sein du complexe SWI/SNF de BCL7 qui interagit avec le module ARP et plus particulièrement avec ACTB par l'intermédiaire d'un motif 2W, et qu’elles sont directement des partenaires de liaisons avec BAF47. Nous avons aussi pu identifier qu’une fois sur les nucléosomes c’est BAF47 qui prend place sur l’acidique patch et l’hélice de BCL7A est déplacé
Chromatin is a dynamic structure regulated by various epigenetic mechanisms, including ATP-dependent chromatin remodeling such as SWI/SNF. Their importance is such that mutations in chromatin remodeling proteins are strongly associated with several diseases, including cancer. For example, BCL7 proteins, which are newly identified core subunits of the mammalian SWI/SNF complex, are associated with different types of cancer, such as Diffuse Large B-cell Lymphoma (DLBCL). To date, information on BCL7 proteins is very limited. Using biochemical and structural approaches, this project aims to better understand the structure and function of these auxiliary subunits. We report here that the proteins bind to the nucleosome with its N-terminal regions, which include an arginine anchoring motif, and that mutation of one of these arginines directly impacts binding to the nucleosome. We also hypothesize that the position within the SWI/SNF complex of BCL7, which interacts with the ARP module and more specifically with ACTB via a 2W motif, is directly linked to BAF47. We were also able to identify that once on the nucleosomes, BAF47 takes its place on the acidic patch and the BCL7A helix is displaced

Résumé :

L’unité cellulaire du muscle squelettique est la myofibre, un syncytium hautement spécialisé générant la contraction musculaire. Au cours de la croissance et de la régénération musculaire, les cellules satellites quiescentes (cellules souches) du muscle squelettique adulte sont activées, prolifèrent puis fusionnent formant de nouvelles fibres. A l’aide d’un modèle murin de régénération et de cultures primaires, j’ai identifié TSHZ3 comme un nouveau marqueur des cellules satellites quiescentes et activées. Dans la lignée cellulaire C2C12, j’ai mis en évidence un effet répresseur spécifique de Tshz3 sur la différenciation myogénique. L’entrée des myoblastes dans la voie de différenciation terminale est déclenchée par le facteur Myogenin (MYOG). L’activation de la transcription du gène myogenin (Myog) est dépendante du facteur MYOD et fait intervenir le complexe de remodelage de la chromatine SWI/SNF. In vitro, TSHZ3 interagit avec BAF57 une sous unité du complexe SWI/SNF. TSHZ3 réprime l’activation dépendante de MYOD sur le promoteur proximal de Myog et cette répression dépend en partie de la présence de BAF57. L’activité répressive et la cinétique d’expression de Tshz3, indique que TSHZ3 pourrait empêcher l’activation prématurée du promoteur Myog lors de la prolifération des cellules satellites activées. TSHZ3 pourrait ainsi participer aux mécanismes de régulation permettant de contrôler l’équilibre entre prolifération, différenciation et renouvellement des progéniteurs myogéniques
Skeletal muscles are made of several units called myofibers, a syncitium into which muscular contraction is generated. During the muscle growth and repair, the quiescent Satellite Cells (SCs; adult stem cells) become activated, proliferate and differentiate to form new multinucleated myofibers. In animal model and primary culture, I found that, Tshz3 was strongly expressed in the quiescent and activated satellite cells.In C2C12 myoblast cells, I showed a specific repressive effect of TSHZ3 on the myogenic differentiation. The terminal differentiation of the myoblastes is trigger by Myogenin (Myog). The transcriptional activation of Myog promoter involves MYOD and the SWI/SNF remodelling complex. In vitro, I showed that TSHZ3 interacts with BAF57, a subunit of the SWI/SNF complex. TSHZ3 represses the MYOD-dependant activation on the Myog promoter. This specific repression involves in part BAF57.The repressive activity of and the temporal dynamic of expression of Tshz3, indicated that TSHZ3 potentially is required to impede the premature activation of the Myog promotor during the SCs proliferation. These results suggest that TSHZ3 plays important roles in the molecular mechanisms operating in activated SCs when there are poised between proliferation, differentiation and self renewal of muscular progenitors

Résumé :

The success of homogeneous asymmetric catalysis has been attributed to the structure and stereochemistry of the coordinated ligand(s). The most effective ligands are C₂-symmetrical bisphosphines containing either a rigid chiral backbone linking two PPh₂ units or a bisphosphine, DIPAMP containing two chiral phosphine units linked by an achiral backbone. The synthesis of P-chiral ligands of this type has been severely hindered by the lack of a general synthetic route allowing the incorporation of phosphorus chirality without the need for separation of diastereomeric precursors or resolution of intermediate enantiomers. The objective of this work was to develop a general synthetic route to homochiral bulky arylphosphines with substantial flexibility in the groups at phosphorus and extend the approach to new P-chiral bisphosphines. In one approach, diastereomerically pure (2R, 4S, 5R)-2,5-diphenyl-3,4-dimethyl-1,3,2-oxazaphospholidine was prepared directly from PhPCl₂ using l-ephedrine as a chiral auxiliary. Stereospecific oxidation using Bu^tOOH gave the corresponding P-oxide which was shown to have R-stereochemistry at phosphorus by single-crystal X-ray diffraction studies. The compound reacted regiospecifically with ortho-anisylmagnesium bromide to afford the product formed by P-O bond cleavage with >96% d.e. and with retention of configuration at phosphorus as demonstrated by single-crystal X-ray diffraction studies. The l-ephedrine residue was replaced by O-methyl under acid-catalysis with inversion of configuration and with >95% e.e., the reaction was monitored by ¹H n.m.r. spectroscopy which gave t_1/2 of ca. 30 min. Attempts to incorporate para-fluorophenol using similar conditions led to the isolation of the pyrophosphinate in low yield. The OMe residue in the methyl (ortho-anisyl)phenylphosphinate was readily displaced by aliphatic Grignard reagents giving the corresponding phosphine oxides with inversion of configuration and with >95% e.e. Displacement of methoxy using aryl magnesium bromides showed similar enantioselectivity but in lower chemical yield, however the corresponding arylmagnesium chlorides were more efficient. In a second approach, diastereomerically pure (2R, 4S, 5R)-2-chloro-3,4-dimethyl-5-phenyl-1,3,2-oxazaphospholidine was prepared from PCl₃ and l-ephedrine. The compound underwent diastereoselective P-C1 cleavage with aryl Grignard and aryllithium reagents with net retention of configuration at phosphorus and with 90% d.e. Oxidation of the ortho-anisyl derivative afforded (2R, 4S, 5R)-2-(ortho-anisyl)-3,4-dimethyl-5-phenyl-1,3,2-oxazaphospholidine-2-oxide which was subsequently reacted with a range of bulky aryl Grignard reagents to afford the corresponding biarylphosphinamides with retention of configuration at phosphorus. Subsequent acid-catalysed methanolysis and displacement of the methoxy residue with PhMgCl afforded a range of bulky arylphosphine oxides with defined configuration at phosphorus with >95% e.e. as determined by ¹H n.m.r. methods. (S)-ortho-anisyl (meta-anisyl)phenylphosphine oxide underwent regiospecific ortho-lithiation on the meta-anisyl ring which on quenching with D₂O afforded the corresponding 2-deuteride in 80% yield. The 2-iodo analogue was also prepared although in low chemical purity and is a key precursor to new axially dissymmetric bisphosphines containing chiral phosphorus centres. Other approaches to P-chiral ferrocenyl ligands and biaryl ligands are also described and modifications for further development are implicated. An X-ray crystallographic study of six aryl-oxazaphospholidines is also presented and demonstrates the influence of the substituents at phosphorus in determining the conformation of the 1,3,2-oxazaphospholidine ring. A comparison with solution ¹H n.m.r. data showed, in some cases, good correlation between the P-O-C-H dihedral angle and the corresponding solid state torsion angle.

Résumé :

The purpose of this research was to explore and gain insight into year 1 undergraduate Physical Education student experiences of learning and develop understanding of the means by which students are supported in the transition to university. It explores the perceived cognitive, affective and social demands on learning; and the challenges and barriers faced by students in becoming academic learners in Higher Education. A qualitative phenomenological approach was adopted. Interpretative phenomenological Analysis (IPA) provides a methodological framework and analytical approach that enables an exploration of the individual [and shared] lived experience of the six research participants. The research is idiographic starting with a detailed exploration of individual experience and perspectives, followed by an interpretative analysis that preserves the participant voice. Semi-structured interviews were conducted at three key points during the first year of study and transcripts were analysed using an iterative, hermeneutic approach. A process of abstraction identified four recurrent master themes that capture the student experience of learning. It is by presenting a holistic understanding of the role that ‘Self’, ‘Becoming’, ‘Belonging’ and ‘Motivation’ play in defining student experiences of learning that this research makes its contribution to knowledge. The findings of this research show that student experiences of learning are individually unique and illustrates the importance of re-evaluating transition. Participants were self-aware but held compound self-concepts that are emotionally and socially defined. Situated and meaningful interaction is critical in fostering resilience and a sense of control over learning and tensions between the relational and connected nature of experience are brought into view. Participants encountered disconnection between certain pedagogies and learning, self-determination and the regulation of study. The conclusion identifies a series of developmental themes that can inform understanding and contribute to further research where the agenda for change seeks to respond to student needs through improvements in teaching and learning; student-centred pedagogy, connectedness, emotional coping, inclusion or exclusion, and mastery oriented learning.

Résumé :

Increasing carbon emissions and insecurities in oil supply have led to heightened interest in hydrogen powered fuel cells. Preferably, the cell runs on hydrogen gas, though due to the sensitivity of the catalytic components in the fuel cell to carbon monoxide, the hydrogen must be extremely pure (typically <50 ppm CO). Due to a lack of hydrogen infrastructure, it is envisaged that a medium term solution will be the reforming of more conventional fuels such as gasoline. The gas mixture produced however, contains impurities such as CO, CO₂ and CH₄. Purification may be achieved using palladium membranes, which allow selective permeation of hydrogen. This thesis describes the research carried out in conjunction with Johnson Matthey on thin (typically 7.5 μm) palladium/silver alloy membranes supported on both ceramic and stainless steel porous tubular substrates. Extensive experimental flow testing has been performed to assess the effect of temperature, feed composition, including wet feeds, and membrane thickness on the hydrogen purification properties. An existing Fortran based model was validated and revised to accurately account for the effects of operating conditions such as temperature and carbon monoxide concentration. This work provided excellent correlation between experimental and simulated results. The validated and improved model was incorporated in the design of a hydrogen refuelling station in Aspen Plus and the palladium membrane requirements assessed to supply 650 fuel cell vehicles per day. The system incorporated a steam reformer, membrane clean-up module, water trap and high pressure compressor for hydrogen storage at 1000 bara. Operating conditions such as system pressure, fuel feed and steam to carbon ratio were investigated and adjusted to optimise the overall system efficiency. An efficiency of 52% was achieved with a steam to carbon ratio of SCR = 2.5. A membrane requirement of 6000 standard tubes was found to provide a 90% hydrogen recovery efficiency.

Résumé :

In an exploratory study, techniques were developed for isolating bulk plant proteins and measuring the ¹³C isotopic compositions of their constituent amino acids by HPLC-IRMS. Samples of plants expected to be of potential palaeodietary significance in northwestern Europe were selected for investigation. Different tissues of plants, leaves and seeds, may be distinguished from each other by the relative ¹³C isotopic compositions (‘isotopic signatures’) of the amino acids of their constituent proteins. For each tissue type, different plant types may be distinguished in the same way. These signatures can vary slightly according to environment and season, but the variation among types is greater than this. For leaves, isotopic signatures can be used to differentiate (i) nettles, (ii) true grasses, (iii) reeds etc, (iv) trees, (v) legumes, (vi) maize, (vii) freshwater plants and (viii) marine algae. For seeds, these signatures are able to differentiate (i) wheat-type cereals, (ii) barley-type cereals, (iii) C4 cereals, (iv) pseudocereals, (v) legumes and (vi) tree nuts. From investigations using a mixing model, it appears that these signals, particularly those of essential amino acids, are reflected in the tissues of their consumers. Freshwater plants are identified as the base of the food chain for dragonfly larvae, marine algae as the diet of marine molluscs and grass as the diet of archaeological cattle and aurochs. Isotopic ‘marine signals’ identified by previous researchers have been refined using these data and the isotopic signatures of fish muscle. These findings are expected to be of particular value in the study of palaeodiets using proteins from archaeological tissues, especially bone and hair. This approach will also find application in the fields of plant physiology and biochemistry.
