Project description:Human astrovirus infection is known to disrupt intestinal barrier function by increasing barrier permeabilty. However, the exact cellular mechanism(s) involved is unknown. We used microarrays to detail the global gene expression changes occuring during astrovirus infection and identify necessary cellular pathways for astrovirus pathogenesis.
Project description:The cellular response to astrovirus infection is not well defined. We used single cell RNA sequencing (scRNA-seq) to determine cellular response to astrovirus early or late in infection.
Project description:Frozen tissue specimens from primary breast tumors were collected under approved protocols and profiled using Affymetrix U133 series expression microarrays. This cohort was assembled at the National University Hospital (NUH), Singapore in 2003, and profiled at the Genome Institute of Singapore, Microarray and Expression Genomics Lab. Dr. Lance D. Miller (Wake Forest University School of medicine) directed the profiling work. A publication describing the generation of these data is not yet available. However, these data can be used alongside other Affymetrix breast tumour data sets to form large meta-cohorts for breast cancer research, as was done in Lasham et. al. J Natl Cancer Inst. 2012 Jan 18;104(2):133-146.
