Activation of CD40 is essential for thymus-dependent humoral immune responses and rescuing B cells from apoptosis. Many of the effects of CD40 are believed to be achieved through altered gene expression. In addition to Bcl-x, a known CD40-regulated antiapoptotic molecule, we identified a related antiapoptotic molecule, A1/Bfl-1, as a CD40-inducible gene.(More)
Two hundred thirty-seven expressed sequence tags (ESTs) of Brassica napus were generated by single-run partial sequencing of 197 random root cDNA clones. A computer search of these root ESTs revealed that 21 ESTs show significant similarity to the protein-coding sequences in the existing data bases, including five stress- or defense-related genes and four(More)
In A549 human lung adenocarcinoma cells, we found that TNF-alpha and several commonly used chemotherapeutic agents upregulated the expression of Bcl-x and/or Bfl-1/A1 through an NF-kappaB-dependent pathway. While parental A549 cells were resistant to the cytotoxic effects of both TNF-alpha and chemotherapy agents, NF-kappaB-blocked A549 cells were(More)
Hepatitis B virus (HBV) prophylaxis is necessary to prevent de novo hepatitis B infection from HbcAb-positive donors. However, which protocol is more effective is somewhat controversial. Also, it is uncertain whether it is necessary to administer HBV prophylaxis for HbsAb-positive recipients. This study attempted to determine whether it is necessary to(More)
A pepper esterase gene (PepEST) that is highly expressed during an incompatible interaction between pepper (Capsicum annuum) and the anthracnose fungus Colletotrichum gloeosporioides has been previously cloned. Glutathione-S-transferase-tagged recombinant PepEST protein expressed in Escherichia coli showed substrate specificity for p-nitrophenyl esters.(More)
The majority of congenital adrenal hyperplasia (CAH) cases arise from mutations in the steroid 21-hydroxylase (CYP21) gene. Without reliance on HLA gene linkage analysis, we have developed primers for differential polymerase chain reaction (PCR) amplification of the CYP21 gene and the non-functional CYP21P gene. Using the amplification created restriction(More)
DNA amplification systems are powerful technologies with the potential to impact a wide range of diagnostic applications. In this study we explored the feasibility and limitations of a modified ligase chain reaction (Gap-LCR) in detection and discrimination of DNAs that differ by a single base. LCR is a DNA amplification technology based on the ligation of(More)
Stool samples of 817 children (grades 4-6) from 3 primary schools, were collected and examined by the antiformin-ether concentration technique. Results showed no cases of Fasciolopsis were found from Liu-Ying primary school (Liu-Ying Hsiang), but infection rates of this fluke were found to be 13.0% and 3.5% for Ho-Chien and Tung-Hsing primary schools(More)
Haemodialysis patients are at higher risk of developing active tuberculosis (TB) infection. However, tuberculin skin tests (TST) have limitations and the diagnostic usefulness of interferon-γ-release assays (IGRAs) remains unclear in immunocompromised hosts including haemodialysis patients. Haemodialysis patients were enrolled from a dialysis centre in(More)
