BACKGROUND Evidence suggests that the growth arrest and DNA damage-inducible gene 45 (Gadd45) is an effective indicator of poor prognosis or malignant potential in solid tumors. The purpose of this study was to determine the gene expression patterns and clinical relevance of Gadd45 in tumor specimens of non-small cell lung cancer (NSCLC) patients. (More)
Survivin is a member of the inhibitor of apoptosis (IAP) gene family known to be involved in resistance to chemo- and radiation therapy. We examined the potential of quantitative survivin mRNA expression to predict histopathologic tumor response and prognosis following neoadjuvant radiochemotherapy (cis-platinum, 5-FU, 36 Gy) in patients with(More)
BACKGROUND The purpose of this study was to evaluate the significance of human telomerase reverse transcriptase (hTERT) mRNA expression and telomerase activity as prognostic markers in non-small cell lung cancer (NSCLC). PATIENTS AND METHODS In a series of 69 curatively resected NSCLC specimens, telomerase activity was analyzed with the telomeric repeat(More)
Cancer of the papilla of Vater (CPV) has a significantly better outcome compared to pancreatic cancer (PC) after curative resection. Increasing evidence suggests that prognostic differences are influenced by a different tumor biology. Secreted protein acidic and rich in cystein (SPARC)/osteonectin is a multifunctional matricellular protein involved in(More)
BACKGROUND Little is known about the role of cyclooxygenase (COX)-2 in gastroesophageal reflux disease (GERD) and the development of Barrett's metaplasia. The objectives of this study were to further analyze COX-2 mRNA expression in patients with GERD compared to Barrett's esophagus (BE) and Barrett's cancer (BC). METHODS Tissue samples from 110 patients(More)
Rifampicin resistance (Rifr) mutations in the RNA polymerase β subunit (rpoB) gene exhibit pleiotropic phenotypes as a result of their effects on the transcription machinery in prokaryotes. However, the differences in the effects of the mutations on the physiology and metabolism of the bacteria remain unknown. In this study, we isolated seven Rifr mutations(More)
Bacillus velezensis is a heterotypic synonym of B. methylotrophicus, B. amyloliquefaciens subsp. plantarum, and Bacillus oryzicola, and has been used to control plant fungal diseases. In order to fully understand the genetic basis of antimicrobial capacities, we did a complete genome sequencing of the endophytic B. velezensis strain CC09. Genes tightly(More)
PURPOSE High expression of cyclooxygenase-2 (COX-2) was shown to inhibit chemotherapy- and radiotherapy-induced apoptosis. We analyzed the association of COX-2 mRNA and protein expression with histomorphologic response to neoadjuvant radiochemotherapy in esophageal cancer. EXPERIMENTAL DESIGN Fifty-two patients with resectable esophageal cancers (cT2-4,(More)
