Abstract (sommario):
Mitochondrial disorders comprise a large group of heterogeneous disorders which are characterized by impairments in the cellular energy production. One of the great challenges of mitochondrial disease is the variety of clinical features present in patients. Mitochondrial disorders affect more than one organ leading to complex multisystem dysfunctions. Tissues, in which the metabolic demand is higher, such as skeletal muscle, neurons, liver or heart are typically affected. Mutations in both mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) often lead to mitochondrial disorders. Although mtDNA en

Abstract (sommario):
In tuberculosis (TB), matrix metalloproteinases (MMPs) have a major role in tissue destruction and cavitation. The composition of each extracellular matrix (ECM) gives specificity to tissues and is important in control of local immune responses by acting as a “molecular postcode”. Hence, it is likely to have important implications in TB. During central nervous system (CNS) infection, the effect of TB on blood-brain barrier (BBB) function is unknown. I hypothesised that the ECM environment may determine the MMP response during innate immune activation in pulmonary and CNS TB. I aimed to investi

Abstract (sommario):
Accidental exposure to arsine (AsH₃) is possible in the semiconductor industry, metal mining, painting and herbicide preparation. First symptoms include intravascular hemolysis and dark red urine (hematuria), followed by abdominal pain, jaundice, and anemia. Exposure to AsH₃ is fatal in up to 25% of the reported human cases, usually caused by acute oliguric renal failure. The mechanism of AsH₃ toxicity in the kidney is unknown and was studied in vitro using established cell lines, primary cells, and isolated kidney. The hypothesis was that AsH₃ cause renal toxicity by its conversion to arsenit

Abstract (sommario):
Mass-spectrometry based proteomics has become an indispensable tool for molecular biology and clinical research because of its ability to identify and quantify thousands of proteins. When combined with laser capture microdissection (LCM), MS-based proteomics may be used to investigate disease-associated changes in the proteome of specific tissue regions or cell populations. Such specificity is essential because different anatomical regions often have distinct and diverse functions and may behave differently under pathological conditions. However, the number of proteins that may be identified a

Abstract (sommario):
Glucocorticoids have diverse physiological functions: they affect central nervous system function, intermediary metabolism and restore homeostasis after stress. Secretion of glucocorticoids is regulated by the hypothalamic-pituitary-adrenal (HPA) axis; negative feedback at the hypothalamus and pituitary suppresses glucocorticoid secretion while the hippocampus exerts additional control over HPA axis activity. Glucocorticoids exert most of their actions, including negative feedback, via the glucocorticoid receptor (GR). The glucocorticoid sensitivity of a given cell/tissue is dependent on the l

The phenotypic variability in human populations is partly the result of gene polymorphisms and differential gene expression. Studying the variability of gene expression across human populations is essential to understanding the molecular basis for diversity. However, key issues remain unanswered with respect to human expression variability. For example, the role of gene methylation in expression variability is uncertain, nor is it clear what role tissue-specific factors may have. Moreover, the contribution that expression variability has in aging and development is unknown. Here we classified

Abstract (sommario):
Macroautophagy is a degradative system that cells employ to degrade proteins, lipids, pathogens or whole organelles. Dysfunctional autophagy has been implicated in diseases ranging from cancer to neurodegeneration. Animal models lacking macroautophagy fail to preserve a functional liver or central nervous system, supporting the importance of autophagy in maintaining the health of these tissues. However, it is unclear why this degradative pathway is critical in maintaining homeostasis. All macroautophagic cargo are sequestered by the multilamellar organelle called the autophagosome. The

碩士<br>國立清華大學<br>生命科學系<br>90<br>Ataxia-telangiectasia (A-T) is a recessive genetic disease that progressively and degenerately affects a startling variety of body systems. Several epidemiological studies have found that patients with A-T heterozygotes tend to have higher risk to develop epithelial carcinoma, especially breast carcinomas. Although tumorigenic mechanisms to explainthe occurance of tissue specificity is not clear, the gene responsible for A-T (ataxia-telangiectasia mutated;ATM) has been identified recently, and it is believed that ATM plays a key role In tumor suppression this dis

Abstract (sommario):
Alongside with the drought, soil salinity is one the major environmental constraints that reduces crop growth and yield worldwide. According to recent reports, salinity stress is costing agricultural sector over US $27.3 billion per annum in lost revenues; which also aggravates the global food security. Improving salinity tolerance is a challenging task that requires understanding key physiological traits in naturally salt tolerant plant species. Halophytes are salt loving plants and they have very diverse array of physiological and biochemical mechanisms to encounter salinity stress. Therefor

Abstract (sommario):
Soil salinity is predicted to become more severe and widespread adding more challenges for sustainable crops production worldwide. Salinity stress tolerance is a complex trait, both physiologically and genetically, and halophytes represent a rich resource for understanding different strategies used by plants to cope with saline condition. While many previous studies explored various physiological and genetic aspects of salinity tolerance in halophytes, most of them were focused on annual species. However, this knowledge is hardly applicable to perennial crops that need to maintain capability o

碩士<br>國立陽明大學<br>生物化學研究所<br>89<br>Abstract The covalent modification of DNA provides a direct and powerful mechanism to regulate gene expression. DNA methylation in eukaryotes involves addition of a methyl group to the carbon 5 position of the cytosine ring. This reaction is catalyzed by DNA methyltransferase in the context of the sequence 5’-CG-3’, which is also referred to as a CpG dinucleotide. It’s the most common eukaryotic DNA modification and is one of the many epigenetic mechanism. This special DNA marking has been closely associated with controlling the expression of houseke

碩士<br>國立海洋大學<br>食品科學系<br>87<br>Zinc concentrations in most tissues of animals and fishes were around 10~50 ppm; however, those in the digestive tract tissue of common carp were found to be extraordinarily high, being 300-500 ppm. It is also known that the nuclei/cell debris fraction was the major fraction responsible for these high concentration of zinc. In order to survey the specificity and affinity of zinc binding substance(s) in the digestive tissue of common carp, 65Zn was added to the Debris Fraction. Binding increased linearly with increase amounts of 65Zn. The Debris Fraction in the di
