Abstract:

Folate deficiency, a prevalent vitamin deficiency in America, can stem from environmental and/or genetic causes. The most common inborn error of folate metabolism is deficiency of methylenetetrahydrofolate reductase (MTHFR), which catalyzes the reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate. Severe MTHFR deficiency results in hyperhomocysteinemia and homocystinuria; patients present with developmental delay, and various neurological and vascular disorders. This thesis describes three mutations identified in the MTHFR locus in patients with severe deficiency: 1025T&rarr

Abstract:

The relationship between colorectal cancer (CRC) and folate metabolism is complex. Dietary folate, depending on the timing and dose, may either prevent or enhance tumour initiation and/or growth, and polymorphisms in the genes encoding folate-metabolising enzymes may also modulate risk. In this thesis, the Apcmin/+ mouse model of CRC was used to investigate the effect of nutritional and genetic disturbances in folate metabolism on tumourigenesis and to examine various mechanisms.<br>The reduced folate carrier I (RFC1) is responsible for the cellular uptake and intestinal absorption of folate,

Abstract:

Methylenetetrahydrofolate reductase (MTHFR) synthesizes 5-methyltetrahydrofolate, a methyl donor for conversion of homocysteine to methionine. A common thermolabile variant causes mild MTHFR deficiency, induces mild hyperhomocysteinemia when plasma folate levels are low and increases risk for neural tube defects (NTD) and pregnancy loss. To increase our understanding of Mthfr regulation, the 5' and 3' regions of the mouse cDNA and gene were characterized. These studies revealed two major promoters, an internal coding exon in the 5'UTR, alternative transcriptional and translational start sites

Abstract:

Hyperhomocysteinemia is a risk factor for cardiovascular disease and stroke. Nutritional and/or genetic disruptions in homocysteine metabolism can cause hyperhomocysteinemia. Mild methylenetetrahydrofolate reductase (MTHFR) deficiency due to the 677C → T mutation in the MTHFR gene is the most common genetic cause of hyperhomocysteinemia. The 677C → T variant is associated with an increased risk for neural tube defects, pregnancy complications, schizophrenia and Down syndrome, and with a decreased risk for colon cancer and leukemia. This variant is also a potential risk factor for vas

Abstract:

Epidemiological evidence linking dietary folate deficiency and risk for colorectal cancer is conflicting. Studies using animal models indicate that timing, dose and presence of pre-malignant lesions will influence whether folate deficiency prevents or promotes tumor formation. In this thesis a new model of spontaneous tumor formation due to long-term dietary folate deficiency alone, in non-transgenic mice and without carcinogen induction, is developed. The mechanisms by which folate deficiency might influence cancer risk are also examined.<br>BALB/c mice, with or without a null allele in a key

Abstract:

Epigenetics is a field of molecular biology that copes with the study of gene function regulation without variations in DNA structure or nucleotide sequences. Among the main epigenetic phenomema in eukaryotic cells there are DNA methylation and post-traslational mechanisms among which the major are histone methylation and acetylation. Epigenetic changes are potentially reversible phenomena that are controlled also by nutritional factors as the methyl-donors involved in the folate cycle. Plasma levels of B vitamins, among which “in primis” plasma folate concentrations, are implicated in epig

Abstract:

Hyperhomocysteinemia, a condition of elevated blood homocysteine level, is an independent risk factor for cardiovascular diseases. Folic acid can effectively reduce blood homocysteine levels. Recent studies have shown that hyperhomocysteinemia is also associated with liver disorders. However, the underlying mechanisms remain unclear. The general objective of my study was to investigate the biochemical and molecular mechanisms of homocysteine-induced liver injury and abnormal lipid metabolism. Hyperhomocysteinemia was induced in Sprague-Dawley rats by feeding a high-methionine diet for 4 weeks.
