OBJECTIVES To investigate the expression and distribution of glycoprotein 340 (gp340), a secretory glycoprotein, in normal human sinus mucosa and inflammatory sinus mucosa and evaluate the possible effects of gp340 on the development of chronic sinusitis. Glycoprotein 340 was identified as a key element in the innate host defense mechanism on many mucosal surfaces and is directly involved in de...
PURPOSE To determine the effects of proinflammatory cytokines on differential gene expression profiles in the human corneal endothelium (HCE), by using a cDNA expression array. METHODS A human cDNA expression array technology was used to study the simultaneous expression of HCE incubated with interleukin (IL)-1alpha and tumor necrosis factor-(TNF)-alpha. Gene-specific semiquantitative reverse...
PURPOSE To determine the effects of transforming growth factor (TGF)-beta2 on immune-response-related gene expression profiles in the stimulated human corneal endothelium (HCE). METHODS A human complementary DNA (cDNA) expression array analysis was used to investigate the effects of TGF-beta2 on cultured HCE incubated with interleukin (IL)-1alpha and tumor necrosis factor (TNF)-alpha. Gene-sp...
Swine hepatitis E virus (HEV) was detected by a semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR) in liver tissue and feces but not in skeletal muscle, pancreas, or heart from pigs experimentally infected intravenously with swine hepatitis E virus (swine HEV). Homogenates of liver tissue and suspensions of feces prepared from swine HEV-infected pigs were inoculated intra...
Park, Keerang, JohnA. Olschowka, LindaA. Richardson, Crescence Bookstein, Eugene B. Chang, and James E. Melvin. Expression of multiple Na1/H1 exchanger isoforms in rat parotid acinar and ductal cells. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G470–G478, 1999.— Several members of the Na1/H1 exchanger gene family (NHE1, NHE2, NHE3, and NHE4) with unique functional properties have bee...
Several members of the Na+/H+exchanger gene family (NHE1, NHE2, NHE3, and NHE4) with unique functional properties have been cloned from rat epithelial tissues. The present study examined the molecular and pharmacological properties of Na+/H+exchange in rat parotid salivary gland cells. In acinar cells superfused with a physiological salt solution (145 mM Na+), Na+/H+exchanger activity was inhib...
We previously described a selective bile duct ligation model to elucidate the process of hepatic fibrogenesis in children with biliary atresia or intrahepatic biliary stenosis. Using this model, we identified changes in the expression of alpha smooth muscle actin (α-SMA) both in the obstructed parenchyma and in the hepatic parenchyma adjacent to the obstruction. However, the expression profiles...
The article describes a polymerase chain reaction (PCR) based method for semiquantitative assessment of mRNA expression for chemotactic cytokines in the lower respiratory tract cells. Cytokine mRNA was detected using PCR preceded by reverse transcription of mRNA into cDNA. The procedures of RNA extraction and of reverse transcription-PCR assay are described in the first part of the article. The...
PURPOSE The AKT/PKB kinase controls many of the intracellular processes that are dysregulated in human cancer, including the suppression of apoptosis and anoikis and the induction of cell cycle progression. Three isoforms of AKT have been identified: AKT-1, -2, and -3. Selective up-regulation of AKT-3 RNA expression has been reported in hormone-independent breast and prostate cancer cell lines ...
