TranscriptomicsMre11 suppresses replication stress and gene amplification proficiency
Gene amplification, copy-number increases of particular genes and surrounding genomic segments, promotes cancer progression and acquired therapy resistance. Thus, understanding genetic traits that confer gene amplification proficiency is important. The primary step for gene amplification is sponta...

TranscriptomicsHuman-specific gene ARHGAP11B promotes basal progenitor amplification and neocortex expansion
The evolutionary expansion of the human neocortex reflects increased amplification of basal progenitors in the subventricular zone, producing more neurons during fetal corticogenesis. Here, we analyze the transcriptomes of distinct progenitor subpopulations isolated by a novel approach from developi...

TranscriptomicsGenome position and gene amplification - expressional profiling of methotrexate resistant colonies
We investigated the influence of genome position on propensity to amplify. First, we integrated a mutant form of DHFR into different positions in the human genome, challenged cells with methotrexate and then studied the genomic alterations arising in drug resistant cells. We observed site specific d...

TranscriptomicsTranscription profiling of mouse samples to compare three amplification methods for nanogram amounts of total RNA
Two T7 based methods One round of Amplification (Affymetrix) and Two round of Amplification were compared to two Ribo-SPIA based systems, RiboSPIA and pico Ribo SPIA systems. Data for Pico-RiboSPIA are listed here. All Hybridisation were performed using Affymetrix Mouse 430-2 gene chips. Data were ...

TranscriptomicsLoss of DNA replication control is a potent initiator of gene amplification
Eukaryotic cells use numerous mechanisms to ensure that no segment of their DNA is re-replicated within a single cell cycle. Despite longstanding speculation that such tight regulation is needed to protect cells from genomic alterations, this notion has never been experimentally tested. Here we show...

TranscriptomicsQuantitative Mammalian Transcriptomics using Designed Primer-based Amplification
We describe a novel quantitative cDNA expression profiling strategy, involving amplification of the majority of mouse transcriptome using a defined set of 44 heptamer primers. The amplification protocol allows for efficient amplification from as low as 50pg of mRNA and did not alter the expression o...

TranscriptomicsGene amplification of the transcription factor DP1 and the CTNND1 in human lung cancer
The search for novel oncogenes is important because these could be the target of future specific anticancer therapies. In the present work, we report the identification of novel amplified genes in lung cancer. In order to find out novel amplified genes in lung cancer, we aligned the gene expression ...

TranscriptomicsIdentification of novel gene amplification events in breast cancer
To identify novel gene amplification events that may contribute to breast cancer progression, we examined copy number variation in 161 primary breast cancer samples using the Affymetrix 250K_Nsp and 250K_Sty microarrays or the Affymetrix SNP5.0 microarray. Affymetrix SNP arrays were performed accor...
