Gene Expression Patterns and Gene Copy Number Changes in Dermatofibrosarcoma Protuberans

Gene expression patterns and gene copy number changes in dermatofibrosarcoma protuberans.

Dermatofibrosarcoma protuberans (DFSP) is an aggressive spindle cell neoplasm. It is associated with the chromosomal translocation, t(17:22), which fuses the COL1A1 and PDGFbeta genes. We determined the characteristic gene expression profile of DFSP and characterized DNA copy number changes in DFSP by array-based comparative genomic hybridization (array CGH). Fresh frozen and formalin-fixed, pa...

Copy number variants, diseases and gene expression.

Copy number variation (CNV) has recently gained considerable interest as a source of genetic variation likely to play a role in phenotypic diversity and evolution. Much effort has been put into the identification and mapping of regions that vary in copy number among seemingly normal individuals in humans and a number of model organisms, using bioinformatics or hybridization-based methods. These...

Dermatofibrosarcoma Protuberans in Childhood

Dermatofibrosarcoma protuberans.

Overview The NCCN Non-Melanoma Skin Cancer Panel has developed these guidelines outlining the treatment of dermatofibrosarcoma protuberans (DFSP) to supplement their other guidelines (NCCN Clinical Practice Guidelines in Oncology [NCCN Guidelines] for Basal Cell and Squamous Cell Skin Cancers and Merkel Cell Carcinoma; to view the most recent version of these guidelines, visit the NCCN Web site...

Influence of gene copy number on self-regulated gene expression.

Using an analytically solvable stochastic model, we study the properties of a simple genetic circuit consisting of multiple copies of a self-regulating gene. We analyse how the variation in gene copy number and the mutations changing the auto-regulation strength affect the steady-state distribution of protein concentration. We predict that one-reporter assay, an experimental method where the ex...
