- Affymetrix Rat Expression 230A Array (rae230a)
Description
Effect of type 1 diabetes (induced by streptozotocin 60 mg/kg) on lung gene expression. Wistar rats, male. At age 8 weeks control rats got IP buffer, diabetic rats got streptozotocin. At age 12 weeks animals were anesthetized and lungs removed. RNA was extracted with Trizol, and gene expression array analysis was performed using Affymetrix RAE 230A microarrays according to the directions from the manufacturer. Arrays were scanned using a Hewlett Packard Gene Array scanner, and analyzed with Affymetrix MAS 5.0 software. Expression levels reported are the output from the MAS software.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Vaccinia virus infection of mouse lungs produces a focal infection within the lung remaining at the large bronchi throughout the course of infection. Animals die of respiratory failure with little edema and few infiltrating immune cells. It is well established that poxviruses control the host immune system by encoding multiple host defense pathway antagonists.

- Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
Efforts to unravel the mechanisms underlying taste sensation (gustation) have largely focused on rodents. The first comprehensive database of gene expression in primate (Macaca fascicularis) taste buds is presented. This database provides a foundation for further studies in diverse aspects of taste biology. A taste bud gene expression database was generated using laser capture microdissection (LCM) of tissue freeze medium OTC embedded macaque tongue tissue blocks. We collected fungiform (FG) taste buds at the front of the tongue, circumvallate (CV) taste buds at the back of the tongue, as well as non-gustatory lingual epithelium (LE). Gene expression was also analyzed in the top and bottom portions of CV taste buds collected using LCM. Samples were collected from 10 animals - 7 female, 3 male.
Publication Title
Genome-wide analysis of gene expression in primate taste buds reveals links to diverse processes.

Description
BACKGROUND: Young age at portoenterostomy has been linked to improved outcome in biliary atresia, but pre-existing biological factors may influence the rate of disease progression. In this study, we aimed to determine whether molecular profiling of the liver identifies stages of disease at diagnosis. METHODS: We examined liver biopsies from 47 infants with biliary atresia enrolled in a prospective observational study. Biopsies were scored for inflammation and fibrosis, used for gene expression profiles, and tested for association with indicators of disease severity, response to surgery, and survival at 2 years. RESULTS: Fourteen of 47 livers displayed prominent features of inflammation (N=9) or fibrosis (N=5), with the remainder showing similar levels of both simultaneously. Differential profiling of gene expression of the 14 livers displayed a unique molecular signature containing 150 gene probes. Applying prediction analysis models, the probes classified 29 of the remaining 33 livers into inflammation or fibrosis. Molecular classification into the two groups was validated by the findings of increased hepatic population of lymphocyte subsets or tissue accumulation of matrix substrates. The groups had no association with traditional markers of liver injury or function, response to surgery, or complications of cirrhosis. However, infants with an inflammation signature were younger, while those with a fibrosis signature had decreased transplant-free survival. CONCLUSION: Molecular profiling at diagnosis of biliary atresia uncovers a signature of inflammation or fibrosis in most livers. This signature may relate to staging of disease at diagnosis and has implications to clinical outcomes.
