Tumor immune tolerance plays a critical role in tumor cell survival; the establishment of tumor immune tolerance is incompletely understood yet. Integrin alphavbeta6 (avb6) is involved in tumor growth and metastasis. This study aimed to observe the effect of avb6 on the development of tumor tolerance in colorectal cancer (CRC). In this study, 28 CRC(More)
OBJECTIVE To investigate the gene expression profile of human gastric adenocarcinoma by means of cDNA microarray and to analyze its biological significance. METHODS Paired tumor and non-tumor specimens from 18 cases of advanced gastric adenocarcinoma were studied. Total RNA was isolated and labeled by reverse transcription reaction with cy5 and cy3 for(More)
The development of a highly efficient and stereoselective methodology for the preparation of beta-hydroxy-alpha-amino acids is described. Nucleophilic addition of enolates of tricyclic iminolactones 1a and 1b to aldehydes in the presence of 6 equiv of lithium chloride in THF at -78 degrees C leads to aldol adducts in good yield (63-86%) and high(More)
T helper 2 (Th2) polarization is a major pathological feature in allergic diseases; its etiology is not fully understood. This study aims to elucidate the adjuvant effect of the microbial product-derived small peptides in the initiation of antigen-specific Th2 polarization. In this study, a clinical survey of patients with chronic rhinosinusitis (CRS) and(More)
OBJECTIVE Aberrant expression of immunoglobulin (Ig) by cancer cells has been documented in a number of malignant tumors but its biological significance is unclear. Cancer cells overexpress anti-apoptotic molecules such as Bcl-xL. The present study aimed to examine the role of expression of Ig light-chain Igk and Iglambda in maintaining the high levels of(More)
Interleukin (IL)-10 plays an important role in immune regulation in the intestine. Immune deregulation is suggested in the pathogenesis of inflammatory bowel disease (IBD). This study aims to elucidate the role of IL-23 in the suppression of IL-10 in the IBD intestinal mucosa. Surgically removed colon specimens were obtained from 16 IBD patients. The(More)
A new, efficient synthesis of sphingofungin F has been accomplished with 10.4% overall yield in 15 steps. The salient features of the synthesis are the utilization of methyl tricyclic iminolactone 3 for the asymmetric aldol reaction as a key step to introduce two desired stereogenic centers, one-pot reaction for the synthesis of omega-hydroxyketone from(More)
The dysfunction of peripheral immune tolerance plays an important role in the pathogenesis of allergic diseases. Recent reports indicate that micro RNA (miR)-98 is associated with the process of aberrant immune responses. This study aims to test a hypothesis that miR-98 is associated with the pathogenesis of airway allergy via interfering with the(More)
OBJECTIVE To detect and identify the potential specific serum biomarkers for diagnosis of papillary thyroid cancer. METHODS Samples of 35 patients with papillary thyroid carcinoma, 40 patients with benign thyroid nodule and 34 healthy individuals were analyzed using the SELDI-TOF ProteinChip System and bioinfomation technology to find the differential(More)
