The Effect Of Mechanical Force On Gene Expression Of Human Bladder Smooth Muscle Cells, Christopher A. Callan Jun 2012

The Effect Of Mechanical Force On Gene Expression Of Human Bladder Smooth Muscle Cells, Christopher A. Callan

PCOM Biomedical Studies Student Scholarship

The purpose of this project is to define, at the molecular level, the process by which gene expression of the extracellular matrix is regulated by mechanical forces in the Human Bladder Smooth Muscle cells (BSMCs). The goal is to first localize several functionally distinct transmembrane proteins; Sarcoglycans (α, β, γ, δ and ε), cytoskeletal proteins Vimentin, and Desmin to verify their presence in the cultured BSMCs using fluorescent-labeled antibodies specific for each protein. The sarcoglycans are primarily responsible for transferring intracellular force generated by the interaction of actin and myosin while the extracellular proteins are responsible for linking the cells …

Down syndrome (DS) is caused by triplication of Human chromosome 21 (Hsa21) and associated with an array of deleterious phenotypes, including mental retardation, heart defects and immunodeficiency. Genome-wide expression patterns of uncultured peripheral blood cells are useful to understanding of DS-associated immune dysfunction. We used a Human Exon microarray to characterize gene expression in uncultured peripheral blood cells derived from DS individuals and age-matched controls from two age groups: neonate (N) and child (C). A total of 174 transcript clusters (gene-level) with eight located on Hsa21 in N group and 383 transcript clusters including 56 on Hsa21 in C group …
