Autism is a neurodevelopmental disorder with unknown etiology, affecting about 1 in 110 children in the US. Here, we show that developmental exposure to anti-brain Abs impaired mouse social behaviors. BTBR mice, a mouse strain with high serum anti-brain Abs and behaviors that resemble autism, have more activated splenic B cells, CD4+ T cells (Th1, Th2 and Th17 subsets), and CD4+ T cells with expression of Vb6 chains than B6 mice (the control H-2 identical strain). Elevated numbers of activated (CD25+) CD4+Vb6+ cells also were detected in thymic preparations. All of the immunological and behavioral parameters of BTBR mice were …
Genetic And Non-Genetic Factors That Cause Inter-Individual Variations In Cyp2a13 Gene Expression, Hong Wu
Genetic And Non-Genetic Factors That Cause Inter-Individual Variations In Cyp2a13 Gene Expression, Hong Wu
Legacy Theses & Dissertations (2009 - 2024)
The overall goal of this dissertation is to investigate the mechanisms underlying the large interindividual variations in susceptibility to lung carcinogenesis. We focused on CYP2A13, a respiratory tract-specifically expressed enzyme, which is the most efficient P450 towards bioactivation of a tobacco-related carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). The expression level of CYP2A13 varies substantially among human lung samples. Our central hypothesis is that CYP2A13 expression level is affected by both genetic regulators and non-genetic factors. The specific aims are 1) to identify the mechanisms underlying the decreased allelic expression of a CYP2A13 allele (7520C>G); 2) to identify frequent single-nucleotide polymorphisms (SNPs), associated …
