Project description:Drosophila PBAP complex, a form of SWI/SNF class of complexes, played a important role in metamorphosis. We conducted MNase digestion followed by next-generation sequencing (NGS) to analyse the nucleosome profile in both control and Brm knockdown fly larvae.

Project description:By using ChIP-seq, we found that loss of BRM activity in developing seedlings leads to ectopic and increased H3K27me3 deposition at several hundred genes, indicating the critical role of BRM in preventing the inappropriate deposition of this histone mark. Removal of CLF in brm mutant could partcially suppress the increased H3K27me3. Examination of H3K27me3 in 14-day-old wt, brm, clf, and brm clf seedlings. Two biological replicates for each one.
Project description:Arabidopsis brm plants depleted in a SWI/SNF-type ATPase BRM have decreased level of endogenous gibberellins and a phenotype that in many respects resembles the phenotype of mutants with repressed GA signaling or biosynthesis, like ga1-3. ga1-3/brm double mutant showed several additive and synergistic effects. To examine whether the phenotypic traits of brm, ga1-3 and ga1-3/brm lines are reflected at the gene expression level, we compared the expression profiles of brm, ga1-3, ga1-3/brm and wild-type plants using microarray analysis. Microarray analysis was performed on total RNA isolated from shoots of 18-d-old wt, brm, ga1-3, and ga1-3/brm seedlings. Three biological replicates were examined for each genotype. Plants were grown simultaneously under the same conditions.
Project description:MNase-seq Experiments from Calorie Restricted and Non-Restricted Yeast from WT, ISW2DEL and ISW2K215R strains We used MNase-seq to study genome-wide nucleosome positions under Calorie Restricted and Non-restricted Saccharomyces cerevisiae
