Both trimellitic anhydride (TMA), a small molecular weight chemical, and ovalbumin (OVA), a reference protein allergen, cause asthma with eosinophilia. To test the hypothesis that different allergens elicit symptoms of asthma via different effector pathways, gene expression was compared in lungs of Balb/c mice sensitized with either TMA or OVA, followed by(More)
Cryptosporidiosis is caused by an obligate intracellular parasite that has eluded global transcriptional or proteomic analysis of the intracellular developmental stages. The transcript abundance for 3,302 genes (87%) of the Cryptosporidium parvum protein coding genome was elucidated over a 72 hr infection within HCT8 cells using Real Time-PCR. The parasite(More)
The role of TNFalpha in regulating apoptotic signaling was investigated during subacute, low-dose (5.0 mg/kg) dimethylnitrosamine (DMN)-induced hepatotoxicity. In TNFalpha receptor (TNFR) intact (wild-type, WT) mice following 4 and 7 DMN exposures, hepatic transcripts for TNFalpha and TNFR-1 were elevated as compared to vehicle controls. DMN hepatotoxicity(More)
Tumor necrosis factor-alpha (TNF-alpha), a crucial mediator in sepsis, elicits multiple biologic effects, including intravascular thrombosis and circulatory shock. TNF-alpha exerts its biologic effects through two distinct cell surface receptors, TNF-R1 and TNF-R2. The pathophysiologic interaction between TNF-alpha and nitric oxide (NO) in glomerular(More)
The impact of Cryptosporidium parvum infection on host cell gene expression was investigated by microarray analysis with an in vitro model using human ileocecal HCT-8 adenocarcinoma cells. We found changes in 333 (2.6%) transcripts at at least two of the five (6, 12, 24, 48, and 72 h) postinfection time points. Fifty-one of the regulated genes were(More)
The enteric immune system of swine protects against infectious and noninfectious environmental insults and discriminates ingested nutrients, food, and commensal microflora from pathogenic agents. The molecular and cellular elements of the immune system have been selected over evolutionary time in response to the specific environment of pigs. Thus, models of(More)

The molecular and cellular elements of the immune system have been selected over evolutionary time in response to the specific environment of pigs. Thus, models of immune function(More)
The size of the poly(A) segment of poly(A)+RNA extracted from hepatocytes isolated from 4- to 30-month-old rats was determined using polyacrylamide-agarose gel electrophoresis. The average size of the poly(A) segment isolated from newly synthesized poly(A)+RNA was 150 nucleotides, and the average size of the poly(A) segment isolated from the steady state(More)
The effect of age on several messenger RNAs coding for non-specific immune factors were determined in liver RNA isolated from 6-, 12-, 24-, 29- and 37-month-old male Fischer Rats. The levels of complement factors C3 and C4, complement protein factor B, and alpha 1-acid glycoprotein were determined by dot blot hybridization using cDNA probes. All four mRNAs(More)
