Project description:We hypothesize that gene expression in the CBs of these two strains of mice are divergent thus contributing to the disparity in the phenotypes. More specifically, (1) genes related to CB function are expressed less in the A/J mice compared to DBA/2J mice; (2) gene expression levels of morphogenic and trophic factors of the CB maybe significantly lower in the A/J mice than the DBA/2J mice. In order to test these hypotheses, we utilized microarray analysis to examine transcriptional differences between CBs of both strains of mice. Keywords: comparative expression profiling

More specifically, (1) genes related to CB function are expressed less in the A/J mice compared to DBA/2J mice; (2) gene expression levels of morphogenic and trophic factors of the CB maybe significantly lower in the A/J mice than the DBA/2J mice. In order to test these hypotheses, we utilized microarray analysis to examine transcriptional differences between CBs of both strains of mice. Experiment Overall Design: . This study utilizes microarray analysis to test these hypotheses. Three sets of CBs were harvested from both strains. RNA was isolated and used for global gene expression profiling (Affymetrix Mouse 430 2.0 array). Statistically significant gene expression was determined as a minimum 6 counts of 9 pairwise comparisons, minimum 1.5-fold change, and p < 0.05.
Project description:We hypothesize that gene expression in the aging lungs of these two strains of mice are divergent thus contributing to the disparity in the phenotypes. More specifically, (1) Aging DBA/2J mice compared to aging C57BL/6 mice are known to be accelerated in their lung physiology and morphometry; (2) C57BL/6J are known to have longer natural longevity than DBA/2J mice. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between aging lungs of both strains of mice.
