A second suture was placed around the right bronchus and pulled tightly to tie off the right lung lobes. The right lung lobes were removed and placed in RNAlater, and the left lung infused under hydrostatic pressure (~30 cm) with neutral buffered formalin. Samples placed in RNAlater were incubated overnight at 4°C and frozen the next day at < 70°C. agent: Air Control treatment repeat: 5 units of treatment repeat: day/wk treatment duration: 5, Units of Duration: day treatment time: 6 units of treatment time: hr/day vehicle for chemical: Air route of exposure: inhalation dose or concentration: 0ppm

RT_0_5d_201_Lung_ACO2_RSTSRP805_Rat_Rat230_2_RSTSRP805_2: Female rats (F344/NCrl) were exposed to chloroprene (CAS 126-99-8) by whole-body inhalation exposure at 0, 5, 30, 90, or 200 ppm. Exposures were performed for 6 hr/day, 5 days per week. The animals were sacrified at 5 days or 19 days (15 exposure days) post initiation of exposure. The right lung was excised and gene expression microarray analysis was performed using Affymetrix Rat 230_2 arrays.
