Achieved biospecimens annotated with patient clinical characteristics are unique resources for translational research. However, RNA extracted from the achieved tissues is often degraded. RNA degradation can have a significant impact on the measure of transcript abundance that can lead to an increase...

Background Transgenic cattle carrying multiple genomic modifications have been produced by sequential gene targeting and serial rounds of somatic cell chromatin transfer (cloning). However, cloning efficiency tends to decline with the increase of rounds of cloning. It is possible that multiple round...

CDC25A is a critical target of checkpoint, and its overexpression is observed in various cancers. Here we demonstrate that in vivo levels of Cdc25A expression determine the efficiency of transformation and tumorigenesis. Transgenic expression of CDC25A in murine mammary glands cooperates with tumor...

Genomic integrity safeguards pluripotency in embryonic stem cells
It has been unclear whether ischemic stroke induces neurogenesis or neuronal DNA-rearrangements in the human neocortex. We show here that neither is the case, using immunohistochemistry, transcriptome-, genome- and ploidy-analyses, and determination of nuclear bomb test-derived 14C-concentration in ...

G-banding of human embryonic stem cells (hESC) has proved their predisposition to aneuploidy of chromosomes 12, 17 and X. Now, using array-based comparative genomic hybridization, we find that hESC also accumulate other recurrent chromosomal abnormalities, such as duplications of stemness genes, sub...

We compared the genomic integrity of human P493 cells grown in vitro with those recovered from xenografts of P493 cells. Keywords: single nucleotide polymorphism, array comparative genomic hybridization

The use of whole genome microarrays for monitoring mutagenised or otherwise engineered genetic derivatives is a potentially powerful tool for checking genomic integrity. Using comparative genomic hybridization of a number of unrelated, directed deletion mutants in Escherichia coli K-12 MG1655 we ide...
