Résumé :

Biology in VIN: Viral Biomarkers to Predict Response to Treatment I Summary Vulval intraepithelial neoplasia (VIN) is a condition of vulval skin that is often chronic in nature. The diagnosis is made histologically and can be delayed due to VINs variable clinical presentation. Frequently reported symptoms of pain and itching can be very distressing for patients. If left untreated, VIN has the potential to become malignant. The current standard treatment for VIN is surgical excision. However this approach is not ideal; it can be disfiguring and lead to significant psychosexual morbidity. There

Résumé :

This thesis investigates possible methods for dose reduction for one of the main contributors to medical x-ray dose, that of fluoroscopic examinations. Background information is provided on the subjects of radiation interaction mechanisms, radiation dose measures, and the health risk from medical x-rays. This illuminates a running theme of the thesis, namely the compromise between image quality and low patient dose. Possible dose reduction methods using both spatial and temporal image processing techniques are investigated. Edge detection is one of the most important sub-components of the spat

Résumé :

Circadian rhythms are present in all living organisms; daily oscillations of biological process from the expression of a gene to the number of times that an animal displays a given behaviour. The light/dark cycle is the primary cue that entrains these rhythms and the suprachiasmatic nuclei, within the hypothalamus are the central pacemaker which synchronises peripheral body clocks. Mice are useful circadian biology models and two peripheral circadian outputs were studied, locomotor activity and the rhythm of body temperature in a common inbred strain, the C57BL/6 mouse.

Résumé :

Soft tissue sarcomas (STS) comprise a heterogenenous group of greater than 50 malignancies of putative mesenchymal cell origin and as such they may arise in diverse tissue types in various anatomical locations throughout the whole body. Collectively they account for approximately 1% of all human malignancies yet have a spectrum of aggressive behaviours amongst their subtypes. They thus pose a particular challenge to manage and remain an under investigated group of cancers with no generally applicable new therapies in the past 40 years and an overall 5-year survival rate that remains stagnant a

Résumé :

Cancer cells preferentially metabolise glucose via aerobic glycolysis (the Warburg effect), which is less energy efficient in teens of ATP production compared to oxidative phosphorylation (OXPHOS). Mitochondrial DNA (mtDNA) encodes proteins of the electron transfer chain and is crucial for functional OXPHOS. MtDNA exists as multiple copies in cells and, often in cancer, there is co-existence of mutant and wild-type mtDNA. There is evidence for mitochondria to contribute towards the tumor biology of multiple myeloma (MM) and glioblastoma multiforme (GBM). The mtDNA from both these cancer types

Résumé :

Mice (30+-3 days old) were exposed to hypergravity (4G, one hour/day). Cross-sections of ankle extensor muscles stained immunohistochemically against slow myosin (MHC) determined if hypergravity affects the distribution of slow muscle fibers. Comparisons (ANOVA) between exposed and unexposed animals show hypergravity causes increases in slow fiber density in soleus after fourteen (p=0.049) and thirty day (p=0.Ol9) exposures. Therefore, loading may induce faster development of soleus through increased slow fiber density. Slow fibers increase in plantaris in males after seven (p=0.008) and in fe

Résumé :

North American Speyeria butterflies are a group whose species hypotheses are confounded by shared wing color patterns between sympatric populations of closely related recognized species due to a putatively recent origin in evolutionary time. Previous studies of this group and the closely related Palearctic genus Argynnis , suggest that Speyeria is monophyletic but derived from within Argynnis . Sampling in these studies has either involved few basal Speyeria species, or too few Argynnis species (Simonsen 2006, Simonsen et al. 2006).

Résumé :

Chronic myeloid leukaemia (CML) is a haematological malignancy that is identified by the presence of a fusion oncogene, BCR-ABL1, which is a constitutive tyrosine kinase. The discovery of tyrosine kinase inhibitors (TKIs) over that past decade has resulted in significantly improved survival rates and disease management in CML patients. However, a subpopulation of BCR-ABL1+ cells in the niche are found which exhibit stem cell-like features, such as self-renewal and quiescence. These CML stem cells (LSCs) are shown to be insensitive to TKI treatment and are capable of deriving the disease during

Résumé :

p53 is a tumour suppressor that is dysfunctional in most cancers. In some cancers, mutation of the TP53 gene results in expression of a mutant protein or loss of p53 expression, while in others wild-type p53 is retained but there is a defect in the mechanisms that allow for the activation of p53, including, but not limited to, upregulation of p53’s negative regulators (MDM2 and MDMX). Restoration of wild-type p53 function can lead to tumour regression and is therefore an attractive anti-cancer therapy. Several small molecule compounds that activate wild-type p53 have been described, and in thi

Colorectal cancer (CRC) is the second most prevalent cancer. Although not typically considered a hormonally responsive malignancy, oestrogens are linked to disease risk and survival. Here, it is hypothesised that oestrogen synthesis, via steroid sulphatase (STS) and 17β-hydroxysteroid dehydrogenases (HSD17β), is promoted in CRC leading to oestrogen-driven tumour proliferation. To identify potential novel treatment targets oestrogen metabolism was characterised in CRC.

Protein tyrosine phosphatases represent a family of signalling enzymes with emerging therapeutic potential.

Aberrant SHP2 signalling underlies the pathology of numerous developmental disorders such as Noonan and LEOPARD syndrome, and is a known driver of breast cancer and myeloproliferative disease.

Little is known about BALF1, including whether BALF1 is pro- or anti-apoptotic. Interactions between BHRF1 and cellular BCL-2 homologues have not been fully characterised, but previous studies have focused on BIM as a key binding partner.

Wnt/β-catenin signalling plays a central role in the regulation of multicelluar organism development and in the maintenance of tissue homeostasis in adults.

TIGAR (TP53-induced glycolysis and apoptosis regulator) functions to promote antioxidant defence, with a loss of TIGAR associated with a defect in a cell’s ability to control reactive oxygen species (ROS) and resultant oxidative damage. TIGAR can function as a fructose-2,6-bisphosphatase, lowering the levels of fructose-2,6- bisphosphate, which is an activator of phosphofructokinase-1. As a consequence, TIGAR activity results in a dampening of the glycolytic pathway and, by enhancing the pentose phosphate pathway, increases cellular antioxidant capacity by promoting the generation of NADPH and

Résumé :

The overall aims of the studies were to obtain objective measures of oral precancerous lesions based upon studies of the cell cycle and to investigate these parameters as possible prognostic indicators with regard to malignant transformation of these lesions. The majority of the precancerous lesions in the present study were dysplastic. These are the lesions which cause the greatest concern clinically with regard to malignant transformation. The first part of the study investigated the S-phase, growth fraction and the relationship of these to each other and with the degree of dysplasia with th

Résumé :

Dendritic cells (DCs) are potent antigen presenting cells and are crucially involved in the induction of the adaptive immune response. Multiple DC subsets exist in the body at rest and during inflammation with unique tissue origins and development. The main function of DCs is the uptake of antigen from the peripheral tissue by endocytosis, and the transfer of this antigen to T cells within the lymph nodes (LNs) to generate an immune response against the antigen. Given the potency of the potential T cell response, DCs are an attractive cell type for therapeutic use in contexts such as cancer. O

Résumé :

Cancer Chemotherapy treatment involves the administration of drugs to patients, these drugs mainly work by interacting with the cell cycle or inhibiting DNA synthesis. Unfortunately, the toxicity of these chemotherapy drugs is severe and can have serious side-effects on different tissues and organs of the body. In chemotherapy treatment about 85% of cancer patients exhibit some degree of liver or kidney damage. Therefore, the aim of this study was to investigate the cytotoxicity of some of the most commonly used chemotherapy drugs; Methotrexate (MTX), Etoposide, Cisplatin and Doxorubicin (DOX)

Résumé :

Clusterin (CLU) is a multifunctional glycoprotein widely expressed as two isoforms. One isoform, sCLU is secreted, cytoplasmic and anti-apoptotic, the other, nCLU, is nuclear and pro-apoptotic. Seven genes, DKK3, TIMP1, CADM1, AKAP12, KLF4, RNASET2 and CLU were identified to be candidate tumour suppressor genes in cervical neoplasia and subsequent validation led to an evaluation of the regulation and expression of CLU at three sites of squamous cancer: the oral cavity, cervix and nasopharynx. Down-regulation of CLU was demonstrated in nasopharyngeal cancer (NPC) and oral cancer and loss of one

Texte intégral

Résumé :

Kaposi’s sarcoma-associated herpesvirus (KSHV) is the causative agent of several human malignancies. Herpesviruses are known to modulate cellular pathways responsible for the recognition and repair of DNA lesions, collectively known as the DNA damage response (DDR). Here it is demonstrated that lytic reactivation of KSHV in B cells results in activation of the ATM and DNA-PK kinases that regulate the response to DNA double-strand breaks (DSBs). This DDR does not depend on amplification of viral DNA and results in phosphorylation of downstream proteins involved in DNA repair, cell cycle regulat

Résumé :

Cancer cells reprogram their metabolism to supply biosynthetic and bioenergetic demands of rapid proliferation. Microenvironmental changes, such as hypoxia, further influence tumour metabolism, driving malignancy. Recent identification of cancer-associated mutations in succinate dehydrogenase (SDH), fumarate hydratase and isocitrate dehydrogenase (IDH) have shown that genetic alterations can directly alter tumour cell metabolism, and may be required for malignant transformation. Mutations in these metabolic enzymes promote tumorigenesis by hijacking the adaptive response to hypoxia. Understand

Résumé :

Primary malignant bone tumours are rare cancers that are characterised by different genetic and epigenetic alterations. A functional epigenomic approach was combined with the Illumina HumanHT-12.v4-BeadChip expression microarray in three Ewing Sarcoma (ES) cell lines to identify genome-wide functional methylation changes in these cells and ES primary samples. This study revealed eight frequently methylated genes in ES patients’ samples, where NPTX2 and PHF11 promoter methylation was associated with poor patient prognosis. The second methylation study involved genome-wide DNA methylation profil

Résumé :

CMV CD8+T-cell memory-inflation can occupy up to 50% of the total CD8+ T cell pool. Studies using an MHC class I immunevasion-deleted strain revealed novel peptide-epitopes across the virus genome both in-frame and translated in a non-canonical manner. This study functionally and phenotypically characterised CD8+T-cells responding to these CMV-derived epitopes with age. They were found to be frequent component of the in vivo repertoire dedicated towards HCMV during latency. A HLA-Cw*0702-restricted immunodominant CD8+T-cell response that accumulated within elderly donors was identified to reac
