The availability of high resolution array comparative genomic hybridization (CGH) platforms has led to increasing complexities in data analysis. Specifically, defining contiguous regions of alterations or segmentation can be computationally intensive and popular algorithms can take hours to days for the processing of arrays comprised of hundreds of thousands to millions of elements. Additionall...
BACKGROUND Cytogenetic analysis of classical Hodgkin's lymphoma is limited by the low content of the neoplastic Hodgkin-Reed-Sternberg cells in the affected tissues. However, available cytogenetic data point to an extreme karyotype complexity. To obtain insights into chromosomal imbalances in classical Hodgkin's lymphoma, we applied array-based comparative genomic hybridization (array comparati...
Copy-number variations (CNVs) may contribute to genetic variation in humans. Reports regarding existence and characteristics of CNVs in a large apparently healthy Japanese cohort are quite limited. We report the data from a screening of 213 unrelated Japanese individuals using comparative genomic hybridization based on a bacterial artificial chromosome microarray (BAC aCGH). In a previous paper...
Array-based comparative genomics hybridization (aCGH) has gained prevalence as an effective technique for measuring structural variations in the genome. Copy-number variations (CNVs) form a large source of genomic structural variation, but it is not known whether phenotypic differences between intra-species groups, such as divergent human populations, or breeds of a domestic animal, can be attr...
BACKGROUND Gliomas are classified into pathologically defined subgroups. However, the tumors in the same entity could show varied 'clinical courses. Recently, various studies revealed that genetic analyses of gliomas can provide clinically relevant information. OBJECTIVE To investigate the correlation between genetic characterization and clinical information of adult supratentorial grade II-I...
دورگه سازی در محل، روشی است که در آن از پروب های اسید نوکلئیک برای بررسی انواع تغییرات ژنتیکی در سلول های دست نخورده و بافت های تثبیت شده استفاده می شود. مراحل مختلف این روش شامل انتخاب پروب، آماده سازی نمونه، تیمار پیش از دورگه سازی، دورگه سازی، شستشو، آشکارسازی و روند کنترل می باشند. انتخاب پروب مناسب یکی از جنبه های مهم انجام فرایند دورگه سازی موفقیت آمیز است. حساسیت و ویژگی in situ hybridiz...
