Project description:Bortezomib is a proteasome inhibitor used in severel different hematological malignancies. Resistance to this drug is still poorly understood. In order get more insight in the resistance mechanism, we developed several bortezomib resistant subclones of the CCRF-CEM T-ALL cell line. On these subclones comparative Genome hybridization (arrayCGH) for DNA copy number analysis gene expression and micro-RNA expression arrays were performed. We performed comparative Genome hybridization (arrayCGH) for DNA copy number analysis on four different bortezomib resistant subclones of the CCRF-CEM cell line. The resistant subclones were compared to the parental CCRF-CEM wildtype cell line and reference DNA.

Project description:Gastric cancer is the second most common cause of cancer death worldwide, but incidence and mortality rates show large variations across different countries. Variation in risk factors between different populations, including environmental and host factors influencing gastric cancer risk, have been reported but little is known about the biological differences between gastric cancers from different geographic locations. We set out to study genomic instability patterns of gastric cancers obtained from patients from United Kingdom (UK) and South Africa (SA). DNA was isolated from 67 gastric adenocarcinomas, 33 UK patients, 9 Caucasian SA patients and 25 native SA patients. Microsatellite instability and chromosomal instability were analyzed by PCR and microarray comparative genomic hybridization, respectively. Data was analyzed by supervised univariate and multivariate analyses as well as unsupervised hierarchical cluster analysis. Tumors from Caucasian and native SA patients showed significantly more microsatellite instable tumors (p<0.05). For the microsatellite stable tumors, geographical origin of the patients correlated with cluster membership, derived from unsupervised hierarchical cluster analysis (p=0.001). Several chromosomal alterations showed significantly different frequencies in tumors from UK patients and native SA patients, but not between UK patients and Caucasian SA patients and between native and Caucasian SA patients. In conclusion, gastric cancers from South African and UK patients show differences in genetic instability patterns, indicating possible different biological mechanisms underlying the disease. 67 gastric adenocarcinomas, 33 UK patients, 9 Caucasian SA patients and 25 native SA patients.

Project description:Bortezomib is a proteasome inhibitor used in severel different hematological malignancies. Resistance to this drug is still poorly understood. In order get more insight in the resistance mechanism, we developed several bortezomib resistant subclones of the THP-1 monocytic/macrophage cell line. On these subclones expression arrays were performed. We performed expression array three different bortezomib resistant subclones of the THP-1 cell line. The resistant subclones were spotted against the parental THP-1 wildtype cell line.
