We examined the relationship among the multidrug resistance (MDR1) gene product P-glycoprotein (P-gp), ulcerative colitis, and immune status under ulcerative colitis. MDR1 P-gp expression and interleukin-8 levels in ulcerative colitis were determined using immunohistochemistry and a double-antibody sandwich avidin-biotin complex-enzyme-linked immunosorbent assay, respectively. ... more
In the struggle for life, the capacity of microorganisms to synthesize and secrete toxic compounds (inhibiting competitors) plays an important role in successful survival of these species. This ability must come together with the capability of being unaffected by these same compounds. Several mechanisms are thought to avoid the toxic effects. One of them is toxin extrusion from the ... more
This study aimed to analyze the spectrum and drug resistance of bacteria isolated from burn patients to provide a reference for rational clinical use of antibiotics. Up to 1914 bacterial strain specimens isolated from burn patients admitted to hospital between 2001 and 2010 were subjected to resistance monitoring by using the K-B paper disk method. Retrospective analysis was performed on ... more
We investigated the effect of autophagy on drug resistance of multiple myeloma (MM) to doxorubicin (DOX). A DOX-resistant MM cell line (RPMI8226/DOX) was developed by progressively increasing the DOX concentration gradient. The drug resistance index was determined using the MTT method. Transmission electron microscopy, anti-light chain 3-fluorescein isothiocyanate immunofluorescence, and ... more
Single nucleotide polymorphisms at codons 167, 198, and 200 in the β-tubulin isotype 1 gene have been associated with benzimidazole resistance. Until now, the only mutation observed in Ancylostoma caninum was at codon 200 of this gene. However, the standardized methodologies used to detect mutations in this species are faulty. The objective of this study was to standardize a ... more
Construction of a human Fab phage display library from antibody repertoires of osteosarcoma patients
Osteosarcoma is the commonest type of primary malignant bone tumor, frequently found in adolescents at sites of rapid bone growth. Despite current management protocols, up to half of the patients succumb to this disease. Moreover, there is no well-characterized molecular marker for diagnosis and prognosis. Since phage display methodology allows the selection of human antibody fragments with ... more
Osteochondroma is a cartilage capped benign tumor developing mainly at the juxta-epiphyseal region of long bones. The rate of malignant transformation, mainly into chondrosarcoma, is estimated to be less than 1-3%. Transformation into osteosarcoma is very rare and has been reported only thirteen times. There is little information on treatment and outcome. We report the case of a secondary ... more
We conducted a comprehensive study to investigate the role of genes involved in metabolic and transport pathways in response to chemotherapy and clinical outcome of osteosarcoma patients. Genotyping of seven gene polymorphisms was performed on a 384-well plate format on the Sequenom MassARRAY platform in 162 patients with osteosarcoma. We studied the correlation of the seven gene ... more
We investigated the association between vascular endothelial growth factor (VEGF) gene +1612G/A, -634C/G, and +936G/C and the clinical outcome of osteosarcoma. Genomic DNA was isolated from blood samples, and 3 VEGF gene polymorphisms (+1612G/A, -634C/G, and +936G/C) were analyzed using polymerase chain reaction-restriction fragment length polymorphism. Of the 194 patients, 82 patients ( ... more
In this study, we investigated the association between a RECQL genetic polymorphism and osteosarcoma in a Chinese population. We selected rs820196 in the RECQL5 gene and genotyped 185 patients with osteosarcoma and 201 age- and gender-matched non-cancer controls. We found that the CC genotype was more frequent in the osteosarcoma group compared to the control group (P = ... more
